Oilfield Drilling Fluids Solids Control Can Make Economic and Environmental Benefits

Jan 14, 2014

Drilling fluids, usually, contains a lot of suspension and colloid. It can be classified into water-based, oil-based mud and hybrid-type mud. In drilling processing, drilling fluids cools, lubricates, and supports the bit and drilling assembly. Besides, the drilling fluids containing barite and floccule can be effective in the balance of formation pressure avoiding well kick and blowout.

During drilling operations, especially in complexly deep well drilling project, drilling bits will inevitably encounter stratum, air layer or underground spring which will dramatically damage the drilling bits, thus hindering drilling processing, and cause downhole accident which will generate security threat. That is reason why drilling fluids is absolutely necessary in the whole drilling project. 
 

Solids Control System
 

But drilling fluids is expensive since it will result in a large abundant drilling cost, so we need to use the drilling fluids for recycling. The solids control equipment are the necessary devices for drilling fluids purification and configuration.

The Function of Solids Control Equipment

In drilling operation, drilling fluids will be injected into formation through drilling pipe, and pumped out with drilling cuttings. Due to the fact that drilling fluids exerts highly destructive effect on environment and costs highly, the solids control equipment emerged as an indispensable devices to purify and circulate drilling fluids in order to increase drilling efficiency and reduce environment pollution.

Oilfield drilling solids control system, or called drilling fluids circulation system is one of the important compositions in the whole drilling rig system. It mainly consists of drilling fluids shale shaker, vacuum degasser, desander, desilter, mud cleaner, and decanter centrifuge. All these solids control equipment serve as a series of sifter in varying shape and sizes, and drilling fluids will be purified by repeatedly going through the layers of filters.

In China oil drilling mud solids control industry, KOSUN is a leader and expert. KOSUN is capable of providing customers with such four series as oil & gas drilling solids control equipment, drilling centrifuge, drilling waste treatment equipment and drilling security equipment, including 25 categories of products, and can also customize packaged design and matching products of oil & gas drilling rigs for drilling contractors. The products provided by KOSUN are extensively used in oil & gas drilling and workover, coalbed methane drilling, shale gas drilling, water well, geothermal well drilling, trenchless horizontal directional crossing projects, mine gravel staged treatment, tailings treatment, rive dredging works, municipal environment-friendly sewage treatment, industrial wastewater treatment, fruit juice purification, waste oil recovery, purification treatment, etc.
