【摘要】 异常压力与油气的关系极为密切 ,研究一个盆地异常压力的特征、成因及主控因素 ,总结其与油气的内在关系 ,对于指导油气勘探具有重要的实际意义。本文在综合运用盆地中央坳陷的测井、地质资料 ,以及各工区的地震剖面 ,迭加速度谱等资料的基础上 ,预测该区的异常压力分布 ,弄清地层压力分布规律 ,分析油气成藏过程和动力机制 ,为盆地新区的进一步开发提供依据更多还原

【Abstract】 Abnormal pressure has an important relation with oil and gas. Studying a basin’s abnormal pressure charac-ter, cause of formation and main control factors and then summarizing the immane nce relation, it has an important practice meaning to guide oil and gas exploita tion. In this paper, on the base of the central depression logging, geolog-ical. data and seismic cross-section, stacking velocity and so on, forecast the abnorm al pressure distribution, understand the formation pressure distribute rules, a nalyze oil and gas form process and kinetic mechanism, this will provide hdpful direction for further exploitation in new basin zones.更多还原
