摘要
利用J.J.Arps提出的3种产量递减公式,以及由此引申出的2种产量递减公式,对洼20区块进行产量递减回归,几种回归方程相关系数均大于0.8,回归结果接近生产实际情况。其中选取具有代表性的双曲线递减方式对油田的未来产量递减情况进行了预测。同时结合油田开发现状,提出了减缓产量递减的对策。
The three production decline formulas proposed by J. J. Arps and the extended two production decline formulas are applied to carry out the production decline regression in Wa 20 block in Dawa Oilfield. The correlation coefficients of several regression equations are all greater than 0.8, and the results are close to the actual production. Typical hyperbolic decline is selected to forecast the future production decline situation. Aimed at the status quo of the oilfield development, the countermeasure is put forward to slow the production decline.
