| 摘 要： | 针对安塞油田长西区低孔隙度、特低渗透率、低含油饱和度和浅层低产的油藏特性,通过大量室内、现场试验研究,优选出适合的压裂施工参数,包括低温压裂液、裂缝支撑半径、前置液和砂液比。采用"深穿透、细分层、快排液"的矿场压裂方法,工艺成功率达99.4%,增产效果显著。

| Abstract: | Aiming at some reservoir characteristics of low porosity,extra-low permeability,low oil saturation,and low productivity as well as shallow depth in Changxi Area of Ansai Oilfield,through a large number of laboratory experiments and field tests,some suitable fracturing technology and operation parameters have been optimized,including low temperature fracturing fluids、propping fracture radius、pre-liquid and sand-fluid ratio. Adopting fracturing techniques of"deep-penetration、fine separate-layer and fast flowback",which has attained a success rate as high as 99.4%,the effects of increasing oil productions are apparent. |
