断块区控制油气富集区─—复杂断块油田形成条件系列论文之五

Rich Pool,Controlled by Fault-Block-Group──Part 5 Forming Conditions of Complicated Fault-Block Oil Fields

“断块区控制油气富集区”是复杂断块油田上最重要的一条规律，它与“二、三级断层控制油气移聚”说的是同一条规律，是两种表达方式，只是有着重声、的不同。后者着重成因机制，前者着重对勘探开发的指导意义。文中阐述了“断块区控制油气富集区”的含义。指出这一规律使复杂断块油田的详探工作分异为寻找富集区和查明富集区两个任务和方法都不同的两个部分。指出了这一规律对寻找富集区，开发富集区的指导作用。

Rich pool is controlled by fault-block-group in complexly faulted oilfield.It is another expression of the rule: ' 2 ~ 3rd class faults play an important role in hydrocarbon migration and accumulation '. Such an expression is beneficial to application in practical work. It has been pointed out that detail exploration in complexly faulted oilfield included two parts: search for rich pool and examine geological condition of rich pool. They have different object and should use different method- In all these work, the relationship between rich pool and fault-block-group should be used as guidence. It can lead to high efficiency with less blindness in practical work.
