摘　　要：　针对安塞油田坪北区低孔隙度、特低渗透率、低含油饱和度、低压、低温、浅层低产岩性的油藏特点,优选出适应低温压裂液、裂缝支撑半径为160m、前置液为15%～20%、平均砂液比为35%～40%、加砂程序15%—25%—35%—45%—55%,压裂施工成功率为99.4%,充分挖掘了油层潜力,增产效果显著。According to some reservoir characteristics of Pingbei Area, such as low porosity, ultralow permeability, low oil saturation, low formation pressure, low temperature, low productivity and shallow buried depth, the lowtemperature hydro fracturing fluid has been researched, and with 160m fracturing proppant radius, 15%～20% concentration of spearhead fluid, 35%～40% average sand proportion, and 15%-25%-35%-45%-55% sand-added sequence. The hydro fracturing success ration is 99.4%. So the reservoir potential has been developed fully and a great effect of stimulation treatment acquired.
