摘要:
基底先存逆断层的后期反转控制苏北盆地海安凹陷形成地垒式构造样式,喜山期右旋扭张应力场的叠加改造,形成了多次凹、扭动型地垒的构造格局。构造控圈、控藏作用明显:基底的差异性沉降控制了古近系阜宁组二段烃源岩的演化差异;在沉积相主体控制下,同沉积二级断层影响阜宁组三段砂岩储层的分布发育;在晚期成藏的条件下,长期活动断层是油气运移有利通道;构造转换带是圈闭发育和油气成藏的有利区。
Abstract:
The late inversion of the basement pre-existing reverse faults controls the formation of a horst structural style in Haian Sag of Subei Basin. The superimposed transformation of right-lateral torsional stress field in the Himalayan period has formed a tectonic pattern of multiple concave and twisting horst. The tectonic controlling on the oil reservoir and trap is obvious:the differential subsidence of the basement controls the evolutionary differences of hydrocarbon source rocks in the second member of the Funing Formation in the Paleogene;under the control of the main body of sedimentary facies, the secondary faults of the same sedimentary affect the distribution and development of sandstone reservoirs in the third member of the Funing Formation;under the conditions of the late reservoir formation,the long-term active faults are favorable pathways for oil and gas migration;the structural transfer zone is a favorable area for traps developing and the hydrocarbon accumulation.
