水平井技术在苏里格气田苏53区块的应用

The Application of Horizontal Well Technology in Su 53 Block of Sulige Gas Field

为了改善气田开发效果,提高采收率,针对苏里格气田直井生产暴露出单井控制储量低、气井产量低、压力下降快、稳产能力较差等一系列问题,在苏53区块开展水平井整体部署技术的研究和应用,取得了良好的效果。形成了水平井区筛选、水平井地质导向、钻井提速及储层改造等特色配套技术,目前水平井在苏53区块已达到规模实施阶段,日产气为临近直井的5~10倍,生产效果较好。该研究为实现水平井技术在苏里格低渗气藏的全面推广应用提供了技术保障。

In order to improve gas field development effect and recovery,according to the problems of low single well controlled reserves,low yield of Gas well,quick drop pressure and poor maintenance capability that exposed during the production of vertical well in Sulige Gas Field.The study and application of horizontal well Integral deployment technology was carried in Su 53 block,and achieved good results.Form the characteristics Supporting technologies such as: the horizontal well area screening,the horizontal well geosteering,well drilling speed acceleration and reservoir reconstruction.At present the horizontal well in Sue 53 block has already reached the scale implementation phase.The daily gas production is 5-10 times than near vertical wells,the production effect is good.This study provide technical support to the Sullige low permeability reservoir for the Comprehensive promotion application of horizontal well technology.
