震荡压裂酸化技术在大斜度高温超深井的应用

Application of Tech about Oscillating Fracturing and Acidizing in the Well with High Angle Deviated,High Temperature,Super Depth

川东北地区气藏埋藏深度大,气藏压力温度较高,流体成分复杂,在大斜度、超深井中完成增产措施则进一步增大了施工难度。震荡压裂酸化技术在川东北地区成功运用,一定程度上沟通了气井底层深部渗流区域,增加泄油气面积、提高了单井产能。

Because of deep gas reservoir,high pressure and temperature,complex fluid composition in north-east area of Sichuan,it is more difficult to finish stimulate in high angle deviated and super deep hole.It communicates percolation region of deep part of bottom layer in gas well in a certain extent,and adds drainage area and improves productivity of single well because of successful application of oscillating fracture and acidizing tech in north east of Sichuan area.
