低孔低渗油藏压裂水平井产能预测

Productivity prediction of fractured horizontal wells in low porosity and low permeability reservoirs

压裂水平井的产能预测往往不同于常规水平井,本文通过油藏工程和数值模拟两种方法对压裂水平井的产能进行预测,考虑了裂缝长度和宽度对产能的影响,分析了水平井与直井的指标对比,为同类油藏水平井的产能预测提供参考依据。

The productivity prediction of fracturing horizontal wells is always different from the conventional horizontal wells.In this paper,two methods are used to predict the productivity of fractured horizontal wells:reservoir engineering and numericalsimulation. Considering the influence of fracture length and width on the productivity,this paper analyzes the index comparisonof horizontal wells and vertical wells and provides the basis for the productivity prediction of fractured horizontal wells in similarreservoirs.
