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。
In view of the fact that low permeability oil and gas fields have become an important resource for the steady development of China’s oil industry, it is imperative to speed up the development of low permeability oil and gas fields. The most basic feature of low permeability oilfields is poor fluid infiltration capacity and low production capacity, which needs to be reformed to maintain normal production . This article summarizes the three major categories of transformation and stimulation technology: hydraulic fracturing technology, explosion and fracturing technology and composite technology. The advantages and disadvantages of all kinds of technologies are analyzed. The latest development of this kind of technologies is analyzed. Finally, the development trend of the technology of low permeability reservoirs is discussed.
