点状注水在窄小砂体油田上的应用

根据低渗透穿小砂体油田砂体规模小、分布零散、单井钻遇层数少、油层薄、厚度小等发育特点，提出了低渗透窄小砂体油田注采系统调整过程中，过分强调平面几何形态规则变化是不利的，不能完套用砂体大面积分布油田的调整方法，应依靠分砂体研究完善单砂体注采系统，采用不规则井点点状水，同时配合油水井工作制度配套调整，在实践中应并收到很好的效果，改善了窄小砂体薄差层油田开发效果，在同类油藏开发具有价值。

Application of Dotty Water Injection on Oil Field with Narrow Sand Body

Oil field with now permeable narrow sand body has the characteristic of small sand body, scattered distribution, less penetrated layer in single well and thin reservoir. This paper proposes that it is unfavorable to stress on areal geometric change in the injection production system adjustment process of low permeable narrow sand body oil field. Abnormal well point dotty water injection can be used with oil and water well working principle adjustment. Application has obtained a nice effect.
