煤层气井高产水对排采产气的影响及改进方案研究

Study on the Effect of Hige-yield Water in CBM Well on Gas Discharge and Production

本文针对高河井田的实际工况,通过地质情况分析其影响产水的主要因素,采用差异性的地质选层和压裂工艺的调整来对新试井进行改进。改进后,有效控制了高产水井的数量,并降低了单井平均产水量,延长了其修井周期。

In this paper, according to the actual working conditions of Gaohe Mine Field, the main factors affecting water production are analyzed through geological conditions, and the new well test is improved by adopting the differential geological layer selection and the adjustment of fracturing technology. After improvement, the number of wells with high water production is effectively controlled, the average water production per well is reduced, and the workover cycle is prolonged.
