摘要
冀中地区大兴断块储层孔洞、裂缝发育,压裂酸化工作液滤失大,地层温度高,基质有效渗透率低、储层污染严重,储层增产改造难度较大。通过分析储层改造难点,提出了相应技术对策,开发了适用于高温裂缝性灰岩储层的酸液体系,提出了三维酸压优化设计技术。研究成果在兴9-4x实施后,增产效果显著。
In Daxing faulted block in Jizhong Area,vugs and fractures are very developed,acidizing or/and fracturing liquid leaks off seriously during operation,the reservoir temperature is high,effective permeability of matrix is low,damage is serious,and so stimulation treatment is very difficult.This paper puts forward a method,based on this understanding,to deal with these problems.A new kind of acidizing liquid suited to this fractured limestone gas reservoir with high temperature and optimizing design technology of acidizing and fracturing in three-dimensions are developed.The results of this study were successfully applied in Well Xing9-4X.
