In accordance with factory products catalog and current information about shale shaker, we mainly can speculate that the main developing tendency for this kind of solids control equipment will be:

(1) deepening working theory research of shale shaker, including reasonable device type, particle movement rule of screen surface, Through screening mechanism and study on the influence of various factors.

(2) refining shaker screen, accelerate the development of screen mesh (80 mesh), ultra-fine mesh (over 200 mesh).

In recent years, the new products in the market focus on screen mesh and most of them are ultra-fine shale shakers. At the same time, in order to make single screen meets the requirements of ultra-fine mesh, new shale shakers usually have double layers. The upper screen is generally 10 to 6 meshes and the lower layer screen has over 200 meshes. To meet the processing requirements, the screen area generally is large, some shale shakers have more than 300 meshes.

(3) keep improving the control and regulatory mechanism of shale shaker. The performance of new shale shakers (including screen box slope angle) are adjustable, and some of them can conveniently adjust the excitation frequency.

(4) to further improve the reliability of the machine and its spare parts, especially the life span of shale shaker screen.

Why Use Solids Control System?

From the long-term drilling practice, solid phase content in the mud and the properties of these solids and type is a key problem for the drilling speed and downhole safety. For this reason, solids control system is widely used in drilling in order to adjust the element of mud.

Knowing the harm of dispersed mud is essential to take proper measures and use proper solids control equipment to solve the problems. When the solid phase content is too high in dispersed mud, and particles are too small, harmful performances are as follows:

(1) When mud solid phase content is of high proportion, ROP decreases and the service life of the drill bit is shorten, and then drilling rate declines.

(2) The large number of cuttings and sand in mud is not easy to remove, mud cake of high permeability, high fluid loss, so that particles of mud filtrate invasion and fine clay oil, gas, destroyed the penetration layer on production and production capacity.

(3) the mud cake thickness, loose texture, high friction coefficient, high fluid loss, cause the formation of expansion, shrinkage, spalling collapse, causing tripping in card, easy happening adhesion sticking and hole collapse drill.

(4) the cementing quality is not good.

(5) The drill bit, drill equipment and mechanical equipment wear, serious early scrapped, the drilling can not be carried out smoothly.

(6) data is not accurate, sand hybrid, electric logging is not smooth, logging data is not accurate.

(7) the mud performance is not stable, high viscosity, shear stress, not good fluidity, easy happening clay contamination and chemical pollution.

(8) waste water, mud treatment agent and a large number of raw materials, the cost and raise the cost of drilling mud.

In a word, to reduce cost, raise efficiency as well as protect the environment, it is necessary to use drilling waste management and oil drilling mud equipment.

Solids Phase and Solids Control System

When it comes to solids control system, solid phase should be mentioned. The solid phase of drilling indicates the solid elements contained in mud, the percentage for volume or mass is the drilling fluid solids content we usually say.

Drilling solid, according to their functions, can be divided into two categories: the useful and harmful solid phase. Because of liquid solid content, particle size and the cost of drilling have essential relationship, drilling fluid solids control appears to be very important in drilling engineering.

The mud solids control is to remove harmful solid mud in the solid phase and preserve useful solid prase. In order to meet the requirements of drilling technology on mud properties. Usually the mud solids control refers to solids control, mud solids control system is generic term all the mud solids control equipment. Modern mud solids control is an important means of modern drilling, for it directly affects the safety, quality, fast drilling and protection of important factors of oil and gas reservoirs, it is also an important symbol of drilling into the scientific stage.

Specifically, the mud solids control has the following functions: prevent oil and gas channel blocking, damage, reduce the drilling torque and friction, reduce the annular suction pressure fluctuations, reduce the possibility of differential pressure sticking, improving drilling speed, prolong the life of the bit, reduce equipment wear, improve the life of wearing parts of the mud circulation system, increasing borehole stability.

In addition, using drilling mud system such as mud tank and mud shaker will improve the underground conduit conditions, reduce environmental pollution, maintain the performance and adjust the mud, reduce drilling costs.

Brightway shale shaker starting and running

Shale shaker has been preset at the factory for most drilling conditions of G-force. After installing the device to adjust the number of screens and screen box angle. Typically, the sieve box amplitude adjustment is not necessary.

Adjust the shaker

Remove the plate from the regulator on the red safety pin (put on both sides of the pin are removed); using the side of the hand wheel adjustment screen box angle, the other side also raised the same angle; when transferred to the desired screen box angle, re-plugged insurance sales, insurance sales must ensure that both sides of the hole the same location.

Usually the drilling conditions, the mud shaker operates in the vertical angle should be between 2 degrees so that the liquid pool just close to the end of the end of the second screen. When the drilling fluid is returned from the bottom of the solid phase more, larger flow containing clay or invoked when a large angle upward, vibrating sieve can increase the amount of the solid phase more dry. But also accelerated the screen wear. Usually happens when the liquid pool close to the end of the end of the second screen, the chip has been fully dry off.

Shaker Screen clogging

If the screen is mounted on the sieve, waste cloth or cloth gloves are available in a circular motion to wipe the screen surface. If the screen has been unloaded, the available high-pressure air or high pressure water blown from below.

Brine fluid can sometimes result in a wire screen appears on the deposition of calcium, the calcium as the thickness of the wire increases, the mesh will be blocked, this often leads to run pulp. Usually steam to clean deposition of calcium.

Covering the wire screen mesh on the other drilling fluid additives or chemicals used to dilute acidic solvent. The water and the acidic solvent ratio of 5:1 was mixed well to clean the screen. Note: Acidic solvents harmful to the skin and eyes, if splashed on the skin, eyes or clothing can be rinsed with water.

The overall configuration of solid control system Part 1

Solid control system is composed of a number of solid-phase clearance equipment, drilling fluid tanks and ancillary equipment and other components. Section has been discussed before solid-phase clearance equipment selection and matching.

1 The system processes

Solid control system, including the drilling waste management from the wellhead to the drilling system circulating pump suction of the process of full facilities. System is placed in the ground mode type I,] and L type three. Drilling fluid from the well head back out secretly by elevated aqueduct or pipe into shale shaker for first grade purification, and then again into the drilling fluid desander desilter and drilling fluid centrifuge second, third and four purification, according to the above, the purification process of the fourth level, the media should be treated desilter underflow or overflow. Such as the application in addition to gas, shall determine the installation position above, in general, should be based on the size of the rig and the level of purification required, the third choice, four purification equipment.

2 System structure type

Tank system for solid removal devices are placed in tanks, in order to ensure the smooth wellhead back out of the injection fluid shale shaker, shale shaker must be based on the inlet height, and height to determine the drilling rig base tank height dimension, but also have to rig level determines the amount of drilling fluid systems.

3 Auxiliary equipment selection

Mud agitator function is to maintain fluid performance stable, and therefore must be fluid discharged from the impeller agitator in the tank to make up the suspended solid phase velocity greater than the downward settling velocity, and thus the impeller diameter and rotational speed of the stirrer given work volume is certain. Working volume mixer to stir the drilling fluid circulation is called the cycle time time time. According to the information abroad, the cycle time is generally 30-90s. In the solid control system, shale shaker placed solid control unit fluids such needs settling tank, so take the maximum cycle time, while the other storage tanks and drilling mud pump tank should take the minimum to ensure drilling performance and stability. Cycle time of 60s is usually taken as the basis for setting the number of agitators
