摘要
国内上报和动用探明储量中,砂砾岩油藏比例明显有所上升,准确地标定可采储量,为有效开发和及时评价提供依据,而目前还没有考虑砂砾岩油藏的特殊储层与渗流特征的采收率预测方法。通过调研砂砾岩油藏开发实例及相关资料,选取典型的胜利油田砂砾岩油藏,详细研究了砂砾岩油藏的渗流机理与开发特征,确定了影响砂砾岩油藏采收率大小的主控因素,建立了适于砂砾岩油藏采收率标定的计算方法。对类似砂砾岩油藏采收率的标定具有重要意义。
Among declared and producing reserves in China,the percentage of oil reserves in sand-gravel reservoirs increased significantly. Accurate calculation of recoverable reserves could provide a basis for effective development and timely evaluation of the reserves,however,there were no methods for predicting oil recovery in consideration of special formation and flowing features in sand-gravel reservoirs nowadays.The typical sand-gravel reservoirs in Shengli Oilfield were selected to study in detail the mechanism of fluid flow in porous medium and exploration characteristics,through investigating case histories and related materials of sand-gravel reservoirs.The major factors controlling the oil recovery of sand-gravel reservoirs were determined,and the recovery calculation methods were established for fitting the sand-gravel reservoirs.The study makes a great sense for calculating the recovery of analogous sand-gravel reservoirs.
