利用物质平衡方法和容积法，提出了计算高饱和压力、高油气比油藏注采比的计算方法，并对有关参数的确定进行了理论推导论证和经验总结。结合文东油田的开发实例进行了实际有效的计算和实际应用，计算结果更加准确合理地反映了文东油田目前开发的实际法采状况，实际应用效果明显，这种方法对油田开发政策的确定具有一定的指导意义。 By means of mass balance method and volumetric method, the calculation method of calculating the ratio of injection to production of high saturated pressure and high oil-gas ratio reservoirs is put forward, and the theoretic deduction and demonstration of relevant parameters are made and the experience is concluded. The actual and effective calculation and practical application are made according to the development examples of Wendong Oilfield. The calculation results more accurately and reasonably reflect the actual mining situation of Wudong oilfield. The actual application effect is obvious. This method determines the development policy of oilfield Has a certain guiding significance.
