摘　　要：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 an important role in oil and gas exploration, drilling engineering and oil and gas development. Today, the drilling area has turned to marine from land. With the development of petroleum exploration, drilling engineering geological conditions are more and more complex, how to integrate a variety of information to realize predrilling pressure prediction has become one of the problems to be solved urgently. In this paper, on the basis of detailed data, formation pressure profile charts of Lingshui LS25-3-1 well before and after drilling were compared, the feasibility of the method in the actual production was effectively proved, which could provide a reliable guarantee for drilling.
