动态相渗与水驱法联解动用储量在海上砂岩油田的应用

Application of Dynamic phase permeation and water flooding combined solution of produced reserves in offshore sandstone oilfield

通过油藏动态数据反算了相对渗透率曲线,结合甲型水驱特征曲线和实验相渗数据,得出了反求水驱地质储量的动态方法并对A油田的水驱地质储量进行计算。该方法既考虑了油田动态,还考虑了油田的油层渗流特征,是利用动态资料推算水驱地质储量方法的发展。同时,从油藏生产实际出发,动态相渗曲线能够更好地反映油藏的整体特性,能对油藏的含水上升规律和剩余油分布做出更好预测。

This paper calculates the relative permeability curve by the reservoir dynamic data,combines the characteristic curve of A water drive and the experimental seepage data,obtains the dynamic method of reverse water drive geological reserves,and calculates the water drive geological reserves of A oilfield.This method not only considers the oilfield dynamics,but also considers the seepage characteristics of the oil reservoir,which is the development of the method of estimating water drive geological reserves.At the same time,from the actual production of the reservoir,the dynamic phase permeability curve can better reflect the overall characteristics of the reservoir,and can better predict the law of water cut rise and the distribution of remaining oil.
