摘要: 根据过井地震剖面上的前震旦系基底杂乱反射特征和下二叠统顶部的削截反射特征, 结合地质及有机地球化学分析资料, 探讨了巴什托普构造、油气藏的形成机制。该构造的形成定型期与深部的寒武一奥陶系、石炭系油气源油气运移在时空上相匹配, 从而形成了石炭系顶部的次生天然气藏和志留一泥盆系的原生油气藏。它们是这一地区今后油气勘探的重要对象。

Abstract: The forming mechanism of Bashituopu structure and oil/gas reservoir has been researched according to the disorder reflection characteristics of pre-Sinian basement in seismic profile across the well and cutting reflection characteristics of the top of Lower Permian, combirxing with geological and organic geochemical analysis data. It is considered that the forming time of Bachituopu structure matches oil and gas migration in deep Cambrian-Ordovician and Carboniferous. These formed the secondary natural gas reservoir in the top of Carboniferous and primary one of Silurian- Devonian, which are an important target for future oil and gas exploration in this area.
