How to adjust drilling fluid process parameter ?

The three main categories of drilling fluids are water based mud (which can be dispersed and none dispersed), none aqueous mud, usually called oil based mud, and gaseous drilling fluid, in which a wide range of gases can be used.
The main functions of drilling fluids include providing hydrostatic pressure to prevent formation fluids from entering into the well bore, clean during drilling, carrying out drill cuttings and suspending the drill cuttings while drilling is paused and the drilling assembly is brought in and out of the hole. The drilling fluid used for a particular job is selected to avoid formation damage and to limit corrosion.
Solid control mainly control drilling fluid used in oilfield. The details are drilling fluid is a fluid used to drill boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes.
Adjusting drilling process parameter and control drilling mud displacement：
The mud displacement should accord to geology condition to control. Controlling the mud displacement is the key of avoiding risk mud in drilling, if it has no risk mud condition when drill the pilot hole, then the probability of ground risk mud condition is less when chambering and back to drag, so after completing the pilot hole, if it balanced with two sides pressure of unearthed point. So in order to reach the purpose, mud displacement must accord the geology to reasonable control.
To achieve effective solids control, there are several steps that should be taken. To start, obtain an effective, dependable, and durable solids control system. Ensure that the solids control system acquired is; hydraulically balanced; is capable of making both a scalp cut and a fine cut; and has sufficient drilling fluid mixing and re-circulating capacity. Do not by-pass the shale shaker or other solid control equipment while drilling. Use the smallest mesh screen possible on the linear motion shale shaker; this will change from formation to formation and will require operators to maintain a variety of screens on hand. Always maintain an adequate inventory of recommended spare parts and screens. Last and not least, a good oilfield solids control system is only effective when you certify and assign rig personnel to be responsible for equipment operation and maintenance. By employing each of these steps, operators can be achieve improved rig performance, improved rates of penetration, reduce waste disposal costs, and reduce mud costs.
KOSUN is specialized in drilling fluid solids control equipment manufacturing in China since 1992.After more 20 years of development and reserach design and manufacturing,KOSUN has been highly experienced in full ranges of solids control equipment including shale shaker, drilling fluids cleaner,vacuum degasser, desilter and drilling mud decanter centrifuge which will ensures mud recycling and achieve mud circulation.
