| 摘 要： | 根据区域构造演化和地层发育特征综合分析认为,由于石西地区石西11 井区J2x-K1q 段发育较低倾角、小断距断层及较高的泥地比值,造成了导油断裂在该井区J2x-K1q 段地层发育泥岩涂抹层形成断层封闭,阻止了下部油气沿该导油断裂运移至下盘高部位的石西11 井K1q 圈闭成藏,由该泥岩涂抹形成的断层封闭也同时阻止了油气向石西6 井同一盘上部层位K1q 圈闭的运移成藏。研究泥岩涂抹效应对研究区及类似地区的油气勘探有一定的帮助。

| Abstract: | Based on the regional structure evolvement and formation character, it is recognized that low dip and small break faults and high shale/stratum value exist in J2x-K1q in Wellblock SX11 in Shixi area, which are the mainly geological reasons resulting in close of the faults by developed shale daubing layers of J2x-K1q and restricting the hydrocarbon accumulation in SX11 well by migration of the lower oil-gas into higher positions (K1q) along the conductive faults. Also, such a close may control the migration of the lower oil-gas into K1q trap at the same wall in SX6 well. The research of fault closure formed by the shale daubing effect can help the researches of oil-gas exploration in studied area and similar areas. |
