摘要
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。
Research on horizontal well technology has been conducted for the gas reservoirs of fluvial facies in the Sulige gas field in coping with the problems occurred in vertical well development and horizontal well implementation in order to improve recovery factor and reduce production cost.4 horizontal wells with average horizontal section of 800m have been implemented and put into production after staged fracturing,with daily gas production 5 to 10 times of the adjacent vertical wells.This research has provided scientific basis for efficient development of the Sulige gas field with less wells.
