利用油藏产量递减曲线判别裂缝存在性及求取储层参数

Discrimination of Existance of Fractures and Evaluation of Reservoir Parameters by Using the Successive Decreasing Output Curves of NaturalFractured Reservoirs

本文采用天然裂缝油藏产量递减规律的数学模型，绘制成典型曲线；用其判别了天然裂缝的存在性；求得储层参数；为文东油田储层的性质提供了重要的依据，因此，本文对裂缝性油藏的预测以及生产管理具有一定的参考价值．

Typical curves were drawn by making use of the mathematical model of successive decreasingoutput curves of natural fractured reservoir The curves are used to discriminate the existance of natural fractures and evaluate the reservoir parameters,which provide important basis for the behaviors of Wendong Oilfield. It is of reference value for the prediction and management of fractured reservoirs.
