Vacuum degasser

The solid control system also has some horizontal vacuum degasser equipped, its working principle is to use vacuum suction fluid, separated by the thin film after turbulent gas pumped by the vacuum pump. However, this horizontal vacuum degasser need to reprovision a pump spray unit, so that the degassed fluid pumped from the vacuum processing chamber. 

Vacuum Degasser installation

(1) Drilling site requirements as long as no obvious tilt can be.

(2) inlet and outlet pipes, vacuum pumping line connections should be sealed and reliable.

(3) before the start of inlet and outlet pipes should end while immersed in the drilling fluid.

(4) Before the start of the first inlet hose on the vacuum pump and water pipe connected, stop for 3-5 minutes, and so filled with water after the pump is started again. At the same time, turn on the gas-water separator plugs, to the gas-water separator was filled with water until the water overflows from the overflow port stop and spin on the plugs. Start should check the motor rotation direction is correct.

(5) Vacuum control valve on the adjusting screw in place has been adjusted at the factory, do not casually adjusted.

Vacuum Degasser maintenance

(1) Vacuum degasser mud tank cover should be cleaned once a week, in order to avoid clogged gas channel.

(2) After use, the rotor should be washed and vacuum tank suction pipe, cut off the power, remove as the hole blocking plate to check parts for damage, and remove foreign objects inside the tank, rinse the tank wall and the rotor.

(3) After each using, the cleaning work should be carried out to ensure the re-use deaerator with good performance.

(4) Operating ambient temperature higher than 300C, the always see vacuum gauge, when the vacuum is less than 0.3 KPa, the water temperature should be maintained within the vacuum pump does not exceed 450C.

(5) For winter using, to promptly release the gas-water separator and pump the water to prevent cracking.

(6) Every month, available to the spindle bearing grease gun filled with sodium based grease filling volume 200ml.

Solids Control Structure and working principle

Solid control system consists of a set of storage tanks and drilling fluid solids control drilling fluid used to remove harmful solid phase composed of a group of devices, storage tanks and solid control of drilling fluid circulation tank with reserve tank is divided into two parts. Ground drilling fluid circulating tank as part of a cycle, the tank surface mounted shaker, vacuum degasser, desander desilter, centrifuges and other equipment for the purification of fluids. Reserve tank is based on the need for preparation of drilling conditions different properties of the drilling fluid, or storage may be used for different drilling conditions of the drilling fluid.


Drilling fluid purification process in the system


1, First purification


Ie mud treatment at the shaker. Preparation of a good drilling fluid under the action of the pump into the bottom of the well, and carry drilling cuttings back to the surface through the wellhead elevated tube into the mud  shaker, the drilling fluid screening out large debris.


2, Second purification


When drilling a gas dip when, through the role of the vacuum degasser will purge gas drilling fluid, thereby restoring the fluid density, fluid viscosity stable.


3, third purification


Two purified fluid supply pump enters through desander Desander, drilling fluid 40 - 60μm or more tiny harmful solid phase is separated desander li.


4, Fourth purification


Three purified by drilling into the supply pump desilter , drilling fluid 15 - 40μm above the tiny harmful solid phase desilter li be isolated.


5, Fifth purification


Four purified by centrifuge feed pump drilling fluid into the centrifuge, the centrifuge will be drilling in 5 - 15μm tiny particles separated.

Liner shaker

The Liner shaker motor using two two separately driven eccentric shaft , in order to obtain a straight line shapes . Avoid the use of high-precision gear rotor forced the two excitation linking practices , so that the structure is greatly simplified.

In the ideal case ,such as the system of two identical motor characteristics , the fulcrum of the stiffness and damping are equal, nor phase exists at startup , two eccentric block synchronization reversal, can achieve linear vibration type . But in fact, because the two are not identical , and start the motor characteristics and other reasons , the two eccentric operation , it is not strictly maintain the relative position shown in Figure 2-9 , when the two eccentric centrifugal force can not be generated by Figure 2-9 superposition manner and offset to produce an unbalanced force , so that the whole screen box spring on the support movement and generate additional swing. It is due to this move and swing. Also the two eccentric automatically follow each other until they reach reverse synchronous rotation . This process is called self- synchronization process. 

The shale shaker is a important equipment in the solid control equipment.Because two asynchronous motor for rotating the normal synchronization process, a sudden stop a willfully motor power.this motor sometimes can not stop turning , it is still a long term with negative 2-axis synchronous rotation . Then sieve pinch inevitable swing , is no longer a stable linear vibration . This is because a q mJ power from the motor shaft , which can be obtained during the vibration part of the energy to overcome the friction torque shaft , but its speed - fixed somewhat reduced, which necessarily and m: between emergence phase angle A. , The question arose AF force . So, still get to follow the surface of the long-term autocorrelation synchronous rotation . If the motor after a power failure during vibration energy can not be obtained in overcoming the friction torque shaft , the motor will slow down gradually . And stops rotating . 

Brightway Design, installation location away from the mud shaker centroid distance, its main purpose is to make the sieve on the swing axis moment of inertia is small, that is to take reduced, Increasing j. Measures to improve the running stability.

Drilling Mud Desander and Desilter

Desanderand Desilter: Desander desilter are made with a hydrocyclone and a cyclone underflow handling and recycling of drilling fluids shale shaker small fine mesh composed. Drilling desander 30-90μm used to remove solid particles; desilter used to remove the 10-30μm solid particles. Carve cyclone and the cyclone particle size D50 is not only related to the size of the structure, but also with the drilling fluid density, density and pressure of the liquid inlet.Drilling desander shale shaker should be used as the second stage solid phase after removal of some equipment, and desilter should be used as the third stage solid-phase removal equipment.

In order to meet the requirements of handling all of the drilling fluid , drilling fluid and desilter desander must be made ​​up of several components cyclone cone . In order to ensure normal operation cyclone . Inlet pressure must be maintained at 0.25 --- 0.35MPa this range. Desilter swirl cone because many long pipeline , the inlet pressure should be whichever is greater ; drilling desander less due to cyclone cones , pipe sections, the inlet pressure is due , whichever is smaller . Inlet pressure depends on the size drilling sand pump matching is reasonable, therefore drilling sand pump selection is critical, usually 40mH2O drilling sand pump head around with the drilling fluid displacement and division desander mud is equal to the amount of the calibration process , you can meet the requirements. 

Meanwhile, in the selection of drilling fluids and desilter desander must take into consideration the maximum displacement of drilling pump , with its reach a reasonable match . Both devices use the time , no strict restrictions , usually in shallow stratigraphic drilling and soft formations , drilling cuttings large particles content is high, the two must be used simultaneously ; at drilling depth strata and hard strata , if with fine mesh shaker can be used directly in addition to handle drilling mud , which have little impact on the quality of drilling fluid purification , and very 
economical.

In the end,Welcome everyone to visit the professional manufacturer which is the leading company for the solids control equipment in china.
