断层封堵性分析在滚动勘探中的应用

Application of the Fault Sealing Characteristics to Rolling Prospecting

摘要: 断层封堵性分析是在这样一条假设下进行的，即断层本身在油气运移过程中既可能起通道作用，也可能起遮挡作用，仅在断层两盘储层相互接触时才起通道作用，储、盖层接触时才起遮挡作用．其分析方法是首先沿断层走向切两盘的断层面剖面图，然后再把两盘剖面迭合，断层封堵性就清楚了。本方法适用于复杂断块、断鼻、断层-岩性圈闭地区的断层封堵性分析．

Abstract: If a container rock is connected with other container rock in two fault walls, then both of them are communicating,if it is connected with the cap rock,then both are non-communicating. According to the above principle,it is beginning of job to analyze and plot a fault planes along fault strike, then both are joined, so the sealing or non -sealing is shown.
