摘　　要：本文对车西地区异常高压的成因机制进行了探讨,并采用测井资料等效深度法进行了地层压力预测。研究表明,该区异常高压主要受控于不均衡压实和有机质生烃两种因素。等效深度法预测的地层压力相对误差较小,能够较好地反映地层压力的连续变化特征,对车西地区异常高压油藏的勘探具有重要意义。The genetic mechanisms of the abnormal pressure in Chexi area were analyzed in details, and the formation pressure was predicted by equivalent depth method based on well loggings. The results show that the abnormal pressure is controlled by disequilibrium compaction and hydrocarbon generation. The formation pressure predicted by equivalent depth method has small relative error and can effectively reflect continuous varying characteristics of pressure, which has critical significance to the exploration of abnormal pressure oil in Chexi area.
