低渗透油田一般砂体分布范围小,油层连续性差,井距过大时,水驱控制程度低,低渗油田的采收率与井网密度的关系密切。对于开发该类油田井网密度的选择,一般情况是首先选用低密度大井距的方式古井,然后再进行逐步的加密完善。为了确定低渗油田合理井网密度,笔者运用油藏数值模拟软件,进行了提高非均质低渗油田开发效果的机理研究。 Low permeability oilfield general distribution of sand body is small, poor continuity of the reservoir, well spacing is too large, the degree of waterflood control is low, low permeability oil field recovery and well density close. For the development of this type of oilfield well density selection, the general situation is the first choice of low density large well spacing ancient well, and then step by step encryption perfect. In order to determine the reasonable well density of low-permeability oilfield, the author uses reservoir numerical simulation software to study the mechanism of improving the development effect of heterogeneous low-permeability oilfield.
