The Influence of Intercalation on the Effect of Thick Reservoir Exploitation

本文研究了夹层对厚油层开发效果的影响。所谓夹层系指岩性致密、孔隙度小于１２％、渗透率小于０．０２０μｍ２的不渗透层或特低渗透层，它把厚油层分成多个独立的流动单元。本文从双河油田厚油层的特点出发，对如何利用夹层改善注水条件。

This paper studies the influence of intercalation on the effect of thick reservoir exploitation. An intercalation is a non-permeable or low permeable layer with its lithology dense; the porosity less than 12 % ; the permeability less than 0.020 μm 2 , and it divides thick reservoirs into a number of independent flow units. This paper, in view of the thick reservoir charecteristics of Shuanghe Oil Field, studies the way of improving flooding conditions and raising the effect of thick reservoir exploitation by means of intercalation
