Description

Plugging agent Composite plugging agent (plugging while drilling) is made from nature polymer based composite, it can be used in well drilling. Because it swells when meets with water, so it has the capacity of plugging, it also has strong adhesive ability, compared with traditional plugging agent, it can be used more expediently, it can combine with all mud system to plug the thief zone and protect low-pressure production zone (oil, nature gas, water, etc.). Physicochemical Properties Appearance: offwhite powder Water content: <*4% PH: **9 Characteristics: It can plug small openings and micro-fractures quickly, used well. It can quickly form a nonpenetrative shielding zone which has certain intensity to stop the liquid and solid phase in the treatment fluid from invading the accumulation layer, protect the accumulation from damage, then we also can get rid of the shielding zone by anti-perforation. It can observably reduce the filtration of the mud, and no influence for the rheology behavior of the mud, also have excellent heat resistence. It can�t be effected by electrolyte pollution, innocuous and harnless. Use-method: Prevention of leakage: **2% Formation sealing of small openings and micro-fracture in sand bed and protection of accumulation : **4% Formation sealing of serious thief zone: **6% Packing: Weave bag outside and plastic bag inside. *5kg/bag allowable error *1% Products should be placed in cool dry place, not exposed in the sun, in order to prevent damage of packing and moisture.
