利用平面径向流公式预测油层自然产能的方法

A Method to Predict Natural Productivity in Oil Zones With the Plane Radial Flow Formula.

以平面径向流公式作为储层自然产能预测的理论基础。在此基础上 ,确定了影响储层自然产能的主要因素。根据大庆地区的实际特点 ,利用测井资料、试油资料建立了油相有效渗透率、地层原油粘度等影响储层自然产能基本参数的计算方法 ,从而形成了一套完善的平面径向流公式预测储层自然产能的技术。在生产中 ,应用这一技术评价大庆地区的探井产能 ,见到了良好的效果。

With the plane radial flow formula as the theoretical basis of natural reservoir productivity forecast, the main factors affecting the productivity are determined. A method to calculate main parameters,e.g.effective oil phase permeability, oil viscosity, etc.,that affect the productivity is worked out with log and production data from Daqing Oilfield, according to which a perfect productivity forecast technique is formed. And, this technique has been sucessfully used in evaluation of reservoir productivity in exploration wells.
