摘　　要：大牛地气田常规水平井加砂压裂工艺中,存在支撑剂回流、沉降、运移堆积的问题,影响压裂效果。为此,进行了纤维脉冲加砂压裂工艺的研究,经过室内评价、设计、施工参数优化,在该气田实施了先导试验,获得了6. 5×10~4m^3/d的无阻流量,与同层位地质显示接近的邻井相比,产量提高了15%左右,取得了较好的效果。In the sand fracturing process of conventional horizontal wells in the Daniudi Gasfield,there are some problems in the backflow,settlement,and migration and accumulation for proppants,which led to the unsatisfactory effects of fracturing in some gas wells.So it was carried out studies on the indoor evaluation,design,construction parameters,and backflow optimization for the fiber pulse sand fracturing.The pilot test was implemented in D66 well.After the fracturing,the unobstructed flow of 6.5×10 4 m 3/d was obtained in the D66 well.Compared with neighboring wells in similar geologic formation,a better result was achieved with an increased oil production of 15%.
