摘要
葵花岛构造沙河街组异常高压形成于东营组沉积末期。断层处于封闭状态是异常高压产生的首要条件，天然气持续不断的聚集是形成异常超压的主要因素，沉积物快速堆积、粘土矿物脱水和高温增压对形成异常高压都有一定的影响。
Overpressure in Shahejie formation of Kuihuadao structure was occurred in the end ofdeposition of Dongying formation. Closed faults were the first condition for occurrence ofoverpressure, and continuous accumulation of gas was the important factor for overpressure. And fast deposition of sediments, dehydration of clay minerals and heat pressureboosting also had some contribution to the abnormal formation pressure.
