| 摘 要： | 随着深水油气勘探开发的快速发展,因地质灾害而发生的石油钻井事故也不断增加。据统计深水钻井大约30%的花费用于解决安全事故,其中大部分用于因地质灾害而引起的安全事故。在钻探之前通过对设计井位进行井场及钻井工程地质灾害评估,找出潜在的危害钻井安全的地质因素,可以在很大程度上避免这类事故的发生。采用以油气勘探为目的的三维地震数据,经二维高分辨率处理,对尼日尔三角洲井场区及钻井过程中可能引起的工程地质灾害因素进行评估,这些因素包括海底滑坡、浅部断层、浅层气、天然气水合物、浅层高压水流、古河谷、泥穿刺与泥火山、异常高压等。研究结果表明,采用三维地震数据经二维高分辨率处理,可得到较为丰富的地质信息,可以满足深水井位对工程地质灾害评估的要求。

| Abstract: | With rapid deepwater oil and gas exploration and development,the accidents of drilling often occur because of geological hazard.According to statistics,30 percent cost of deepwater drilling has been spent on the accidents caused mostly by geological hazard.Actually,the accidents could be avoided through making a survey of well site prior to drilling to identify potential hazards.In this paper,well site engineering geohazard is studied through 3D seismic data for the purpose of oil and gas exploration,which ... |
