【摘要】：准确计算储层压裂改造体积有助于评估压裂效果及部署开发方案。针对微地震事件点分布边界不规则、储层压裂改造体积难以准确计算的问题,在前人研究的基础上,选用基于Delaunay三角形剖分的Alphashape方法,研发了基于微地震监测数据的储层压裂改造体积估算方法,并编写了算法程序,解决了利用微地震事件点估计不规则边界的问题,较为准确地计算出了储层压裂改造体积。利用该方法计算了砂砾岩体、泥页岩、致密砂岩等不同类型储层压裂改造体积,结果显示该方法具有较好的稳定性和适用性,能够适用于评价各类非常规储层压裂改造效果。
[Abstract]:Accurate calculation of reservoir fracturing volume is helpful to evaluate the fracturing effect and to deploy the development plan. Aiming at the problem that the distribution boundary of microseismic event points is irregular and the volume of reservoir fracturing reconstruction is difficult to calculate accurately, the Alphashape method based on Delaunay triangulation is selected on the basis of previous studies. A method for estimating reservoir fracturing volume based on microseismic monitoring data is developed, and an algorithm program is developed to solve the problem of estimating irregular boundary by using microseismic event points, and to calculate reservoir fracturing volume accurately. This method is used to calculate the fracturing volume of different types of reservoirs, such as gravel rock, shale and tight sandstone, etc. The results show that this method has good stability and applicability, and can be used to evaluate the fracturing effect of various unconventional reservoirs.
