The shielding temporary plugging agent is composed of rigid particles, fiber materials and softening particles. It is deformable, easy to flow, can quickly form a shielding layer, stable performance, and has a certain strength, can withstand a certain pressure, can minimize the damage of killing fluid to the gas reservoir, and the repair pressure recovery is not less than 95% of the original pressure. The preparation of shielding temporary plugging agent is simple, the effect is obvious, and the pressure is easy to recover after repair, which is conducive to the follow-up development of gas field.
In view of the problems of low formation pressure coefficient, serious water sensitivity, hot wash fluid leakage and polluted formation, shielding and temporary plugging technology is introduced to overcome the drawbacks of conventional well washing and long drainage time and decreased production. The technology is characterized by effective plugging and easy plugging removal.
