二十世纪二十年代,地学工作者开始应用厚度法建地层厚度宝塔图,进行构造史反演。在一个油田,不同时期构造运动强度亦存在明显的平面差异。因此我们在对一个油气田的油气水分布规律进行研究时,应先对该区构造运动史、构造运动平面差异等进行充分研究,从而认清油气聚集规律。通常,构造运动较弱区,形成断裂较少,下部储层易形成较大规模油气圈闭;构造运动较强区,形成断裂较多,下部圈闭易被破坏,油气沿断层向上运移,形成次生油气藏。
In the 1920s, geoscientists began to apply the thickness method to build a pagoda map of the thickness of the stratum for the inversion of tectonic history. There is also a clear plane difference in the tectonic activity at different stages in an oilfield. Therefore, when studying the law of oil and gas distribution in an oil and gas field, we should fully study the history of tectonic movement and the difference of tectonic movement in this area so as to understand the law of hydrocarbon accumulation. In general, the tectonic movement is weaker with fewer faults and the lower reservoirs are likely to form large-scale hydrocarbon traps. For stronger tectonic movements, more faults are formed, the lower traps are easily destroyed, and the oil and gas migrate upward along faults. Formation of secondary reservoirs.
