东海西湖凹陷浙东中央背斜带中南部油气成藏规律与晚期剪切断层的关系探讨

摘要: 浙东中央背斜带中南部由于生储盖条件良好,加上处于生烃区内,使区内的圈闭均能形成油气藏。因此,浙东中央背斜带中南部的油气成藏规律就变成了油气藏的保存规律。由于浙东中央背斜带中南部油气藏的保存主要取决于晚期剪切断层,因此对晚期剪切断层的研究,确定晚期切断层对油气藏的破坏规律,就可基本解决浙东中央背斜带中南部的油气成藏规律。Abstract: The trap in the south and middle part of Zhedong Central Anticline Area all can form oil and gas accumulation because of the good condition of the source rocks,the reservoirs and the covers.And then,the pattern of oil and gas accumulation in the south and middle part of Zhedong Central Anticline Area becomes the pattern of oil and gas conservation.Because the oil and gas conservation was controlled by the late shear fault, the pattern of oil and gas accumlation in the south and middle part of Zhedong Central Anticline Area can be studied by analyzing how the oil and gas accumulation were destroyed by the late shear fault.
