的第一级泥浆处理设备，它的组成部分主要有： Drilling fluid vibrating screen is the first-level mud processing equipment of solid control system . Its components are as follows:
的处理压力，平时调节阀门处于关闭状态。 The mud returns from the wellhead and is guided through the pipeline to the mud shaker logging tank. The mud tank acts as a buffer to allow the mud to flow into the screen uniformly. There is an adjusting valve below the logging tank. When it is large, you can open the adjustment valve as appropriate, and let a part directly flow into the mud tank to reduce the processing pressure of the drilling fluid shaker . The adjustment valve is usually closed.
The mud is buffered into the screen installed on the screen box by the logging tank to remove solid phase particles larger than the screen mesh number. The screen box is used as the carrier of the mud vibrating screen. The mud purification process is performed here. The carrier of the vibration motor connected above the screen box excites the beam. The vibration motor installed on the excitation beam generates excitation force to drive the screen The vibration of the box, so as to achieve the purpose of purifying the mud.
在整套固控系统中有着重要的作用，是关系到整套系统能否正常运转的关键，振动筛的正常运转给其他的固控设备在后面的处理中减轻了危害。 The drilling fluid vibrating screen plays an important role in the entire solid control system and is the key to the normal operation of the entire system. The normal operation of the vibrating screen reduces the harm to other solid control equipment in the subsequent processing.Read More »
连续振动，如果钻井液振动筛没有振动，就不能清除钻屑。 When the drilling fluid is circulating, the drilling fluid shaker must be continuously vibrated. If the drilling fluid shaker is not vibrating, the cuttings cannot be removed.
1. The drilling fluid must flow through most of the screen area. If the drilling fluid can only cover 1/4 ~ 1/3 of the screen, it means that the number of screens used is too large;
2. The holes on the screen must be repaired or replaced. The holes on the flat screen can be blocked. Install the screen in accordance with the installation procedure provided by the manufacturer. When drilling fluid flows through the screen mesh, the cuttings will Cannot be separated
3. The screen must be replaced as soon as possible. 停止运行，这样就会降低钻井液中固相的清除数量； When the drilling fluid shaker is stopped during replacement, the amount of solid phase removal in the drilling fluid will be reduced;
4. Before starting to replace the screen, put the tools and prepare a new screen. If conditions permit, you can equip an assistant;
5. If possible, it is best to replace the screen when receiving a single root. In some emergency situations, the drilling project may stop the pump (or reduce the pump speed) and stop drilling when the screen is changed;
6. In order to improve the service life of the screen under no tension, each component of the screen tension system must be guaranteed.
7. Inspect the operating environment of the drilling fluid vibration screen isolation element and the supporting parts of the screen. If damage or excessive fatigue occurs, it should be replaced in time;
8. Do not add water directly in the liquid storage tank or the drilling fluid shaker screen. Water can only be added to the next level process;
9. Unless the loop returns, the entire process must pass Read More »
，形成合理、高效的固控流程，可以清除钻井液中的有害固相，保留有用固相，满足钻井工艺对钻井液性能的要求。 Drilling fluid solid phase control (abbreviated as solid control) system is to control harmful solid phase particles in drilling fluid. By scientifically arranging solid control equipment , a reasonable and efficient solid control process can be removed to remove harmful solid phases in drilling fluid Retain useful solid phase to meet drilling fluid performance requirements.
The deep well drilling fluid solid control system uses five levels of solid control. The solid control process is as follows:
First-level solid control-remove large particles. The drilling fluid returned through the bottomhole circulation contains larger cuttings. The drilling fluid enters the vibrating screen through the connection pipe from the wellhead to the 1 # tank. The vibrating screen is used to screen out the cuttings with a particle size greater than 74 μm. First-level solid control.
Secondary solids control-remove gas. The vacuum degasser is a special drilling fluid processing equipment used to remove the gas invading the drilling fluid during the drilling process. It can quickly and effectively remove the gas (including air) contained in the drilling fluid. The degasser is useful for recovering the drilling fluid. It plays an important role in preventing the occurrence of potential blowout and well collapse danger.
Three-level solid control-remove larger particles. 中，除砂器将钻井液较大的砂粒(粒度44μm～74μm)分离出来，完成除砂过程，即为三级固控。 The drilling fluid that has been processed by the vibrating screen enters into the sand remover . The sand remover separates the larger sand particles (grain size 44μm ～ 74μm) of the drilling fluid, and completes the sand removal process, that is, three-level solid control.
Four-level solid control-remove small particles. The drilling fluid treated by the sand remover enters into the desilter, and the small mud particles (grain size 15μm ～ 44μm) of the drilling fluid are separated by the desilter, and the desilting process is completed, which is the four-level solid control.
Five-level solid control-remove smaller particles. The drilling fluid treated by the desilter enters the centrifuge. The centrifuge separates the smaller sand (grain size 2μm ～ 15μm) of the drilling fluid, and completes the centrifugation process, which is the five-level solid control.
All of the five-level solid control are mainly used for complex well conditions and demanding well conditions. In actual use, according to the needs of drilling operations,
Adopt one or more levels of solid control processes. 后的钻井液固相含量，可以完全达到国内钻井作业对钻井液质量的要求。 The solid phase content of drilling fluid after five-level solid control equipment can fully meet the drilling fluid quality requirements of domestic drilling operations.
、除砂除泥器的关键，了解旋流器的分类详情能够更好的选择泥浆处理设备。 Cyclone is the key to solid control equipment cleaners and sand and mud removal devices. Knowing the classification details of cyclones can better choose mud treatment equipment.
Cyclones can be divided into three types: sand remover, desilter and micro cyclone according to their diameter.
1. Sand remover: A cyclone with a diameter of 150 ~ 300mm is called a sand remover. Its ability to handle drilling fluid is generally not less than 20 ~ 120mm³ / h when the input pressure is 0.2Mpa. A normal sand remover can remove approximately 95% of cuttings larger than 74μm and 50% of cuttings larger than 44 microns. When selecting a sand remover, its allowable processing capacity should be 1.25 times the maximum displacement when drilling.
。 2. Desilter: A cyclone with a diameter of 100 ~ 150mm is called a desilter . When the input pressure is 0.25Mpa, its processing capacity is not less than 10 ~ 15m³ / h. Under normal working conditions, the sand remover can remove 95% of cuttings larger than 44 microns and 50% of cuttings larger than 15 microns. The allowable capacity of the desilter should be 1.25 to 1.5 times the maximum displacement when drilling.
：直径为50mm的旋流器称为微型旋流器。 3. Micro cyclone : A cyclone with a diameter of 50mm is called a micro cyclone. Its processing capacity is not less than 5m3 / h when the input pressure is 0.25Mpa. Separated particles range from 7 to 25 microns. Mainly used in non-heavy drilling fluids to remove ultrafine particles
