闭合酸压作为酸化和酸压结合的工艺，是指在大于地层破裂压力的情况下高排量注入酸液，然后在低于地层破裂压力的情况下注入酸液，溶蚀增加裂缝的宽度。本文主要对闭合酸压的原理、酸蚀裂缝的有效距离、导流能力以及闭合酸压的施工工艺进行论述。
閉閤痠壓作為痠化和痠壓結閤的工藝，是指在大于地層破裂壓力的情況下高排量註入痠液，然後在低于地層破裂壓力的情況下註入痠液，溶蝕增加裂縫的寬度。本文主要對閉閤痠壓的原理、痠蝕裂縫的有效距離、導流能力以及閉閤痠壓的施工工藝進行論述。

Closed acid fracturing refers to the process in which a large amount of acid is injected into the well when the operating pressure is larger than that of formation fracture,then the acid is injected to erode and extend cracks after the operating pressure is lower than that of formation fracture.This paper describes the acid etching,conductivity as well as principle and construction of closed acid fracturing.
