摘要
从压裂裂缝与储层匹配性角度提出将酸压改造纳入油井的钻井、完井设计考虑中,根据海相碳酸盐岩储层的特殊性提出了以缝洞体识别为主的分段优化依据和原则以及以地震资料识别为主的缝洞体识别技术,并介绍了水平井分段改造主要使用的工具,通过分段酸压技术的系统研究在塔中号气田62-11H井进行了现场试验,改造后初期日产油量接近200 tPd,而产水量却下降到40 m3Pd,取得了很好的增油控水效果。
From the perspective of fracturing fracture and reservoir match acid pressure is proposed to transform into the well drilling and completion design consideration, is put forward according to the particularity of Marine carbonate reservoir section optimization basis is given priority to with joint body piercing recognition and principles as well as the seam is given priority to with seismic data to identify the body piercing identification technology, and introduced the main use of tools, horizontal well section reconstruction by piecewise acid fracturing technology system research gas field in the tower through the field test of 6211 h well after transforming oil production in the early days is close to 200 tPd, and the water rate is down to about 40 m3Pd, has obtained the good effect of oil increase water control.
