|
摘要
基于油藏工程方法和渗流力学理论,结合含水上升规律和产量递减规律,建立油田开发指标快速预测方法,幵编写指标计算程序。以平台寿命25 a为计算标准,分析不同原油黏度下的采收率与采液速度变化关系,研究海上油田平台寿命内的合理采液速度。研究结果表明:在平台寿命的25 a末,使油田综合含水刚好达到98%的采液速度为合理采液速度;绘制了不同原油黏度下的合理采液速度图版,原油黏度取值在0.5～50mPa·s内时,合理的采液速度为4.5%～12%;研究了渤海B油田采液情况,当前油田采液速度为8.4%,图版预测合理采液速度为9.5%,该图版可作为后续平台采液速度设计的基础。
Based on reservoir engineering method and seepage mechanics theory, combined with the law of water cut rising and the law of production decline, a fast prediction method for oil field development index was established,computing program was compiled. Based on the 25-year service life of offshore platform, the relation between the recovery ratio and the liquid withdraw rate of different oil viscosity was analyzed, the rational liquid withdraw rate based on the service life of offshore platform was studied. The results showed that, in the service life of offshore platform, the liquid withdraw rate which made the water content of the oil field to reach 98% was rational. The plate of rational liquid withdraw rate with different oil viscosity was drawn. When the value of the oil viscosity was taken from 0.5 to 50 mPa·s, the value of rational liquid withdraw rate was from 4.5% to 12%. The liquid withdraw rate of Bohai B oil field was studied, the current liquid withdraw rate was 8.4%, which was close to 9.5% of the rational liquid withdraw rate plate, the plate could be used as the basis of designing the liquid withdraw rate.
