摘要
天然或人工水驱油田水驱机制起主导作用后,所绘制的甲、乙型水驱特征曲线,其直线段出现的旱、晚、曲折和相关程度对不同油田情况各异。运用直线段及其变化或样板曲线,可以衡量容积法求得的地质储量的准确性,判别水驱状态、措施效果和预测最终采收率等重要生产指标,并可以指导同类型油田的开发。 将童氏水驱曲线分析法编制TX微机软件,只要输入有关数据,即可得到需要的水驱曲线和有关指标。本文以柴达木盆地L—5油田、克拉玛依油田和苏联几个大油田为例,进行了水驱曲线分析,作了较为详尽的比较和探讨。
The water drive performance curves of the first and second types can be drawn after the natural or artificial water drive mechanism prevails in an oil field. The time when the straight line starts, the tortuosity and correlativity for the straight line are different for various fields. The straight line and its changes, as well as type curves, can be used to consider the accuracy of geological reserves in place estimated with volumetrical method and some important performance terms, can be used to identify the state of water drive and the result of treatment, and to predict the ultimate recovery. They can also be used to guide the development for the same type of fields.A computer program of the Tong's analysis method of water drive performance curve was written on a TX microcomputer soft ware. T he required water drive curves and the resuitant performance indices can be obtained with the orogram when the relevant data are input into the computer. In this paper water drive curve analyses were performed for the L-5 field in Caidamu Basin, Karamay field and some large oil fields in USSR. The results were compared and discussed in delail.
