摘　　要：海拉尔地区布达特群油层岩芯资料获取困难、低压低渗等原因给压裂选层带来困难。对该类油层测试压力曲线类型及其反映的储层性质进行分析,结合近几年的压裂效果,总结出海拉尔布达特群油层压裂选层原则:若压力早期恢复速度大于0.05 MPa/h,应当进行压裂;否则,不宜进行。该方法对提高压裂成功率具有重要意义。The difficult of obtaining sand core and reasons of low porosity and low percolation formation in Budatequn oil layer of Hailarer region bring difficult for selecting fractured layer.Analyzing type of pressure testing curve and the reservoir property reflected by it and combing with fruits in these years,the principle for selecting fracture oil layer is summarized which is that if the rare of forepart build-up pressure is over 0.05MPa/h,the fracture operation is needed.
