基于示功图探究抽油机井产量计算

Calculation of output of pumping well based on indicator diagram

多级压裂水平井开采技术既有水平井的优点,同时兼具人工压裂的开发长处,成为有效开发致密砂岩油藏的重要技术手段。本文基于不稳定渗流理论建立了多级压裂水平井试井模型,模型考虑了裂缝属性、裂缝间距和全段射孔的。选取一口多级压裂水平井进行试井分析,并通过对比微破裂影像资料证实级压裂水平井试井解释模型的正确性和实用性。

Multilevel fractured horizontal well mining technology integrates the development advantages of horizontal well and artificial fracturing,and has become an important technical means for the effective development of tight sandstone reservoir.Well test analysis is an important way to obtain reservoir and fracture parameters.Based on the unsteady seepage flow theory,a test model of multistage fracturing horizontal well fracture properties,crack spacing and intact considering perforation completion;well test analysis for a multistage fracturing horizontal well real side data,and micro fracture image data analysis and comparison,verify the correctness of the well test interpretation model of multistage fracturing horizontal well and practical.
