摘　　要：针对苏里格气田单井产量低、水平井开发无法达到预期效果等问题,运用苏里格地区水平井开发经验,在苏53区块开展水平井整体开发试验。利用数值模拟、地震反演、微地震裂缝监测等技术手段,进行油气富集区优选、整体部署、地质导向、压裂增产等关键技术研究。研究表明：开发区适合采用600 m×1 200 m不规则菱形井网开发,合理水平段长度为1 000~1 200m。目前区块天然气生产能力为20.0×108m3/a,水平井初期平均单井产气量超过8.0×104m3/d。研究成果对致密砂岩气藏水平井整体开发具有指导意义。The development of Sulige gas field is featured by low single- well gas production rate and unsatisfactory horizontal well performance. Considering development experiences by horizontal wells in Sulige,integrated development pilot test by horizontal well is implemented in Su53 block. Numerical simulation,seismic inversion,microseismic fracture monitoring and other methods are used to study the key technologies of enrichment region identification,geosteering,fracturing,etc. Research demonstrates that the optimum well employment is 600 × 1 200 m irregular diamond well pattern,and the optimum horizontal section length is 1 000- 1200 m. The present gas production capacity of this block is 20. 0 × 108m3/ a,and the average initial gas production rate of horizontal well exceeds 8. 0 × 104m3/ d. This research could provide references for integrated development of tight sandstone gas reservoirs by horizontal well.
