Mud cleaner is secondary and tertiary of drilling mud solids control equipment, it is the cyclone desanding and desilting cyclone and underflow vibrating screen, three to one. Mud cleaner structure is compact, small footprint area, powerful, is to secondary and tertiary drilling mud solids control equipment the ideal choice for efficient cleaner. Mud cleaner by the sewage pump, cyclone desander, vibrating screen, connect the hose assembly. Mud cleaner use purpose is to reduce useless solid content in slurry, maintain the good performance of mud, and reduce the emissions of waste pulp, thus saving the pulping water and pulp material. Through several drilling mud material consumption statistics contrast can be seen that under the condition of the coal measures strata and the construction of the same aperture, correctly understand how to use mud cleaner, can further improve the mud property, decrease the cost of mud.
The field construction of the machine is equipped with corresponding mud purification equipment, to make all sorts of equipment can give full play to its due effect, must also have a complete and reasonable use of technology, namely, how to use mud cleaner. Mud purification equipment on how to use mud cleaner should pay attention to the following aspects.
How to use mud cleaner:
1, before the start of preparation
1) Check the fastening cover and all the fixed part;
2) Check whether the pipeline fixed, each row of the sand mouth was clear;
3) Check the wear condition of drilling fluid shale shaker sieve, replace when necessary;
4) dial eccentric shaft by hand for a week, should be flexible shine;
2, first start drilling fluid shale shaker, then start drilling sand pump;
3, through the gate to adjust working pressure (drilling fluid desander: 0.2-0.35 MPa, desilter: 0.32 MPa).
4, stop drilling sand pump, open the channel backflow mouth, river mouths, prevent mud loss.
Considerations on how to use mud cleaner:
1. The use of the polyurethane cyclone temperature greater than 80 ℃, the lowest not less than 30 ℃.
2. The cyclone feeding solid particles in the biggest be less than 1/10 of the feed mouth narrow edge width, such as more coarse particle should screen out in advance;
3. Often visited sand pump feed, equipment, hydrocyclone grit mouth is abnormal, and so on and so forth.
Maintenance fit how to use mud cleaner:
1, clean the vortex tube after the usage and remove the bottom block sand;
2, cleaning sieve and timely replacement of the damaged screen;
3, the eccentric shaft bearing lubrication and maintenance once a week;
In recent years, the development of solids control equipment in China soon, but there is a great gap compared with abroad. So the development of complete varieties and specifications, reliable performance, suitable for different drilling requirements of form a complete set of solids control equipment is still the top priority. At present, many units are listing how to use mud cleaner as an important part of drilling mud technology. However, some companies are still paying no attention to how to use mud cleaner and the promotion management work is not in place. As to promote the use of solids control equipment, we should continue to focus on how to strengthen management use mud cleaner. Knowing how to use mud cleaner reasonably, do a good job using the statistical analysis to optimize improvement, give full play to the role of the solids control equipment, production of drilling able to implement efficient, safe and economic.
