通过压裂裂缝监测解释来预测储层产量

Prediction of Reservoir productivity by Monitoring and Interpreting Fracturing Fractures

水力压裂是油气井增产、注水井增注的一项重要技术措施[1]。水力压裂实时监测及解释技术是确保压裂施工取得理想效果的关键性手段,也是水力压裂技术的最新进展和发展趋势。压裂井裂缝参数是决定压裂效果最主要的因素,优选压裂参数可以提高效益,节约成本[2]。本文主要讲了通过地层闭合应力分析、施工摩阻分析和净压力拟合分析来进行进行裂缝参数解释,从而得出储层的产量预测。

The hydraulic fracturing is an important technical measure to increase production of oil and gas wells,augment injection in injection wells.The real-time monitoring and interpretation of hydraulic fracturing technology is not only a key means to ensure the fracturing effect,but also development trend of the hydraulic fracturing technology.Fracturing parameters of fractured wells are the most important factors to determine the fracturing effect;the preferred fracturing parameters can improve the efficiency and save cost.In this paper,fracture parameters were interpreted by the formation closure stress analysis,the construction friction Analysis and the net pressure fitting analysis,and then reservoir productivity was predicted.
