Technology characteristics: Taking on the effective layer flow rheological model, it possesses high displacement efficiency, thin cement sheath, high compressive strength and toughness, and the impact resistance.
Application situation: It has been widely used in deep and super-deep well cementing without centralizers in Tarim oilfield, Tahe oilfield, northeastern and westernSichuanprovince. Most of the cementing is beyond 6000 meters deep with the maximum depth of 8408meters. The overall distinct rate in evaluation is 73%.
