地层孔隙压力作为一个地质参数在油气勘探、钻井工程及油气开发中占有十分重要的地位。如今的钻井区域已经由陆地转向海洋,由浅海转向深海发展。随着石油勘探开发进程的不断推进,钻井工程所面临的地质条件越来越复杂,就钻井工程而言,孔隙压力是实现快速、安全、经济钻进的一个必不可少的重要参数,如何综合利用各种信息在钻井之前准确预测,已成为钻井工程迫切需要解决的问题之一。本文依据大量的详实数据,将陵水LS25-3-1井在钻前与钻后的地层压力剖面图加以对比分析,有力地论述了该方法在实际生产实践中的可行性,为钻井提供可靠保障。
As a geological parameter, formation pore pressure plays a very important role in oil and gas exploration, drilling engineering and oil and gas development. Today’s drilling area has been turned from land to sea, from shallow water to deep sea development. With the continuous advancement of petroleum exploration and development, the geological conditions for drilling engineering are becoming more and more complicated. As far as drilling engineering is concerned, pore pressure is an indispensable and important parameter to realize rapid, safe and economical drilling. How to synthesize Predicting accurately before drilling using various information has become one of the urgent problems to be solved in drilling engineering. Based on a large amount of detailed data, this paper compares and analyzes the formation pressure profile of Lingshui LS25-3-1 well before drilling and drills, and discusses the feasibility of this method in actual production practice and provides a reliable Protection.
