大庆油田开发后期,曾起主力作用的厚油层中部和底部大部分已水淹或水洗,其挖潜能力减弱。但厚油层上部还存在1/3厚度的油层动用程度很差,这部分油层正是保持油田稳产、增加可采储量、油层挖潜的主要对象。

This technique can be described as follows:combine the fracturing technology and the chemical water shutoff technology, form artificial compartment in thick reservoir, change the water flood condition, and thus produce more oil from it. While conducting, the requirements for the pipe string technology are strict:the sticking distance must be short, the fracture must be located; the pipe string should not only meet the requirements of fracturing technology, but also of waiting-on water shutoff technology.
