随着油田勘探领域的扩大,钻井完井作业中高温高压问题成为最突出的技术难题之一。实践证明,无论是在我国陆地还是海洋钻井完井作业中,都普遍存在着异常高温和高压的问题,且具有分布广、压力变化范围大的特点。石油公司为了寻找新的机遇,需要在更为恶劣的环境下钻井施工。本文主要介绍高压气井的特点以及井控方法。 With the expansion of oilfield exploration, the issue of high temperature and pressure in drilling and completion operations has become one of the most prominent technical problems. Practice has proved that no matter in China’s land or sea drilling and completion operations, there are widespread problems of abnormal high temperature and high pressure, and has a wide distribution, large pressure changes in the characteristics. In search of new opportunities, oil companies need to drill in more adverse conditions. This paper introduces the characteristics of high-pressure gas wells and well control methods.
