近几年来, 分层加砂压裂工艺在低渗透砂岩油气藏油井两层以上储层改造中, 得到了越来越多的重视和应用。结合腰滩油田腰9井应用情况, 阐述了该工艺适用条件及特点, 着重介绍了分层加砂压裂工艺原理和流程。应用表明该工艺能降低作业成本, 提高油井产能和效率, 值得推广应用。

In recent years, the separate layers sand fracturing technique have got more and more attention and application in the reformation of more than 2 layers of the low permeable sandstone oil and gas reservoir. This paper presents the applied conditions and characteristics of the technique, and emphatically introduces the principle and process flow of the separate layers sand fracturing technique by combining its application in Yao 9 well. The application shows that the technique can lower the operation cost, improve the oil well deliverability and efficiency, and is worth spreading.
