低渗透油气藏改造技术研究进展

鉴于目前低渗透油气田已经成为我国石油工业稳定发展的重要资源,加快低渗透油气田的开发势在必行,低渗透油田最基本的特点就是流体渗透能力差、产能低,需要进行改造才能维持正常生产。本文主要总结了三大类改造增产技术:水力压裂技术、爆炸压裂技术和复合技术。分析了各类技术的优点、存在的问题以及该类技术的最新发展,最后对低渗透油藏的改造增产技术的发展趋势作了展望。

The stimulation technology development used for low permeability reservoir

The exploitation of low permeability reservoir will be faster and faster,because it is an important resource in oil industry of our countryside.The main character of the low permeability reservoir is low permeability and low productivity,so the improvement is need.In this paper,three kinds of stimulation technology are summarized,and there are hydraulic fracture,exploding fracture,and compound fracture technology.Their advantages,the open questions and the recent development are analyzed.At last,the prospect of stimulation technology for the low permeability reservoir is studied.
