为改善苏里格气田开发效果,提高区块采收率,达到降低开采成本、合理高效开发的目的,针对苏里格气田直井开发中存在的问题及水平井实施中的技术难点,开展了河流相沉积气藏水平井技术攻关与研究。现场实施4口水平井,完钻水平段平均长度为800 m,分段压裂后投产,日产气为邻近直井产量的5～10倍,生产效果较好。该研究为苏里格气田实现少井高效开发提供了良好的途径和科学依据。
In order to improve the development effect of Sulige gas field, improve the recovery rate of blocks, achieve the goal of reducing mining costs and develop reasonably and efficiently, in view of the problems existing in the development of vertical wells in Sulige gas field and technical difficulties in the implementation of horizontal wells, Research and Research on Horizontal Wells in Sedimentary Gas Reservoir. Four horizontal wells were drilled in the field. The average length of the horizontal drilling was 800 m. After the fracturing, it was put into operation and the daily production was 5 to 10 times of the output of the adjacent vertical well. The production effect was good. The study provides a good way and scientific basis for the Sulige gas field to realize the development of less efficient wells.
