北塘凹陷断裂特征与油气分布规律
Analysis on the stochastic characteristic of the hydrauic conductivity of bottom stratum , beitang reservoir , tianjin city
北塘水库库底地层渗透系数的随机特性分析
With a differential accumulation analysis of the fault closeness and the difference of faulted reservoir in beitang depression , it is suggested that ( 1 ) an inactive fault in clastic sequence may mainly restrict hydrocarbon migration ; ( 2 ) undercompacted shales with overpressure can lead to strongly restricting hydrocarbon migration along faults ; ( 3 ) hydrocarbon segregation associated with fault traps more probably takes place in undercompacted zone with abnormal hydropressure
通过黄骅坳陷北塘凹陷断层的封闭性及断层油气藏差异聚集分析，表明断层在活动停止期主要起封闭作用，但在正常压实层序段仍有少量轻组分的烃类沿断层发生运移而引起差异聚集；而在欠压实带，异常高孔隙流体压力使断层在纵向上具有很强的封闭性。
