近年来,随着油田的深入开发,钻井工作量逐年加大,钻采难度逐年提高,为了实现提高钻速、降低成本、环保无污染等效果。各油田各大钻井公司纷纷突出以科技为核心的战略决策,大力发展常规钻井技术,不断应用以空气钻井、复合钻井技术等为先导的新技术,本文结合本人实际工作经验,介绍了国内一些油田常用的钻井技术及一些钻井新技术的前景展望。 In recent years, with the in-depth development of the oilfield, the workload of drilling has been increasing year by year, and the difficulty of drilling and mining has been increasing year by year. In order to achieve the effect of increasing the drilling speed, reducing the cost and avoiding environmental pollution, The major drilling companies in the oilfields have all made strategic decisions focusing on science and technology. They have made great efforts to develop conventional drilling technology and continuously apply new technologies led by air drilling and composite drilling technology. Based on their actual working experience, this paper introduces some domestic oilfields Commonly used drilling technology and some prospects of drilling new technology.
