摘要： 在两种常规水驱特征 曲线的基础上,建立了一种新型广义水驱曲线,绘出了某对应的含水率与可采采出程度之间的关系图。结合生产数据,采用试凑法通过改变n的值,拟合出了曲线表达式,利用该表达式计算了新疆某区块可采储量,并对比了常规的甲、乙、丙、丁型水驱曲线计算结果;求出了该区块含水率与可采采出程度关系式。结果表明:应用新建立的广义水驱曲线预测该区块含水率.上升规律是可行的,且当n值为-0.051时预测效果最好。

Abstract: Based on two types of conventional log-log water drive characteristic curves, a new generalized water drive curve is built up, with its relation chart between water cut and reserves recovery percent corresponding to the characteristic curve. Integrated with actual production data, using cut and trial method to change n value, the simulated expression of such a curve is given, by which the recoverable reserves of a block in Xinjiang region are calculated, and compared with the calculated results by conventional I, II, II and IV types of water drive curves, presenting the expression of water cut vs. reserves recovery percent. The case study shows that it is feasible to predict the rising trend of water cut in this block using this new generalized water drive characteristic curve. When n=-0.051, the water cut prediction is the most accurate.

Key words: generalized water drive characteristic curve, water cut, recovery percent, oilfield development
