摘　　要：针对七个泉油田油藏埋深浅、渗透率低、地层温度低、压力系数低、储层水敏性强等地质特征 ,进行了油基压裂液的试验研究。提出了适合该油田的油基压裂液体系。采用该油基压裂液体系对七个泉油田3口井进行了压裂改造现场试验 ,显著提高了压裂改造有效率 ,取得了良好的增产效果。In consideration of some characters of smaller buried depth, low permeability, low temperature in formation, smaller pressure coefficient and strong water sensitivity in Qigequan oilfield reservoirs, an experimental study is performed by means of an oil based fracturing fluid and a suitable fracturing fluid system is proposed The fluid system is used in fracturing test on 3 wells in Qigequan oilfield, which shows that the effectiveness of fracturing stimulation is raised substantially and the effect of stimulation is excellent
