我国大多数油田已经进入高含水开发阶段。对于一些老岩层来说,由于开采初期没能做好油藏检测工作,不同层之间的注采关系十分混乱,以至于到了高含水阶段后,平面之间,层与层之间矛盾都在加剧。不同与以往的分析方法,从水驱砂岩油田小层注采关系入手,提出了关于小层关系对于油田开发的一理论方法,这套方法在部分油井得到利用,效果显著。 Most of our country’s oilfields have entered the high-water development stage. For some old rock formations, because of the inability to perform reservoir detection in the early stage of mining, the relationship between the injection and production of different layers is very confusing, so that after the high water-cut stage, the conflicts between the planes and between layers are Exacerbated. Different from the previous analysis methods, starting from the relationship between injection and production of small layers in waterflooding sandstone oilfield, a theoretical method about the relationship between small layers for oilfield development is put forward. The method has been applied in some oil wells and the effect is obvious.
