摘要
对目前广泛运用的童宪章水驱经验公式进行推导,在此基础上研究水驱特征曲线在矿场应用中存在的问题,对该经验公式进行修正,并提出计算水驱地质储量的新方法。根据中国3个油田共7个油藏的实际生产数据资料对提出的方法进行验证。结果表明:利用童宪章水驱经验公式预测的油藏最终采收率结果偏大,计算的水驱地质储量结果有误;利用修正后的方法计算的水驱地质储量更接近于用容积法计算的地质储量。
The water drive empirical formula proposed by TONG Xian-zhang was derived firstly, which is widely used cur- rently. The problems in the field application of water drive curves were studied. A new method for calculating water drive ge- ological reserves was developed. Actual production data of seven reservoirs in three oilfields were used to verify the new method. The results show that the reservoir ultimate recovery predicted by TONG Xian-zhang water drive empirical formula is on the high side, and the calculated water drive geological reserves have error. The water drive geological reserves calculated by the revised method are close to that calculated by volumetric method.
