摘要:
 为了提高低渗透砂岩储层压裂改造效果和节省费用支出，有必要在压裂前进行措施选层。收集了近百口低渗透砂岩储层压裂措施井压前地层测试资料，采用统计分析技术，提出了针对此类储层的压裂选层方法。该方法通过总结压前地层测试资料与压裂效果优劣的相关规律性，按照压裂效果从优到劣将地层测试曲线分为七大类型，并形成指导压裂选层的标准图版，同时针对不同类型指定对应的选层标准和原则，使用时仅依据目标井压前测试资料特征，就可以对其是否具备措施潜力做出预判性决策，2019年在二连油田乌兰花凹陷储层成功应用4井层，措施选层准确率100%。应用结果表明，该方法能够实现对所有低渗透砂岩储层压裂效果的有效预测，简单实用、可靠，通用性强。
Abstract:
In order to improve the fracturing effect of lowpermeability sandstone reservoir and save costs, the formation test data of nearly 100 fractured wells before fracturing in lowpermeability sandstone reservoir are collected, and the fracturing layer selection method for lowpermeability sandstone reservoir is proposed by using statistical analysis technology. By summarizing the correlation between prefracturing formation test data and fracturing effect, the formation test curve is divided into seven types according to the fracturing effect from good to bad, and a standard chart is formed to guide fracturing layer selection. For different types, the corresponding selection criteria and principles are specified. In addition, according to the characteristics of the prefracturing test data of the target well, the predictive decision is made on whether it has the potential of fracturing. In 2019, this method was successfully applied for 4 wells/layers in Wulanhua sag of Erlian Oilfield, and the accuracy rate of layer selection was 100%. This method has a good guidance for effective prediction of fracturing effect of all lowpermeability sandstone reservoirs.
