屏蔽暂堵技术在较短时间内形成的高强度屏蔽环既能有效保护地层又能有效防漏堵漏，屏蔽环强度的高低直接决定地层的承压能力。本文利用屏蔽暂堵原理，在实验室内利用普通钻井液进行改良，通过人工造缝的岩芯进行室内实验，通过对比分析两组实验的不同结果，得出具有实际意义的结论，指导现场的实际工作。

Shielding temporary plugging technique is of importance to protection of formation of interest with effective circulation controlling and plugging. Strength of filter cake has exerts a tremendous influence on pressurized capacity of the formation. This paper uses common drilling fluid for making an experimental study of enhancing pressurized capacity of filter cake based on principle of shielding temporary plugging technique.
