在石油开采中，已研究了一种用于确定过量产水产气机理的新方法，并得到了验证。以油藏水锥和水窜问题的系统数值模拟为基础，人们发现，驱替机理不同，WOR与时间及GOR与时间的双对数图表现出不同的特征，利用WOR或GOR对时间的导数可以判别油井是水锥还是气锥，是高渗层见水还是井底附近水窜。该方法对德克萨斯、加利福尼亚、墨西哥湾岸区和阿拉斯加油田的某些井进行了应用，利用实际生产数据图，确定产生问题的机理。结合油井测试和生产测井资料，利用该方法选择措施井，并对增产措施进行优化，可以加速投资的回收。
In oil exploration, a new method for determining the mechanism of gas production by overproducing water has been studied and validated. Based on the numerical simulation of the system of water coning and water channeling in reservoirs, it was found that the driving mechanism of double displacement was different between WOR and time and between GOR and time. Using WOR or GOR’s derivative of time It can be judged whether the oil well is water coning or gas coning, whether it is water seepage in the high permeable layer or water channeling near the bottom of the well. The method applies to some wells in Texas, California, the Gulf Coast, and the Alaskan field, using actual production data charts to identify the mechanics that cause the problem. Combined with well testing and production logging data, this method can be used to select wells and optimize the stimulation measures to speed up the recovery of investment.
