中国深水录井工程实践与发展方向探讨

Practice and developing trend of mud logging engineering indeep water of China

随着油气勘探向深水区迈进,深水录井担负着油气发现和工程监测两大任务。深水井的水深温度差异,隔水管和增压泵的使用特性等决定了深水录井的主要影响因素,为及时准确发现油气并全方位进行工程监测以保障钻井安全,在南海的自营深水钻探中,采用智能综合录井系统geoNEXT、FLAIR流体录井、Prevue实时压力录井、多种含油检测和岩样鉴定技术等组合,取得了良好的录井效果。基于多口井的自营深水录井实践,阐述了中国深水录井应形成具有深水特色的录井解释标准,同时应突破地面发展深水随钻录井技术,搭建井场与远程一体化平台等发展方向。

With oil and gas exploration moving to deep water,deep water mud logging is charged with two tasks of oil and gas discovery and engineering monitoring.There is temperature difference in water depth of deep water wells,the performances of risers and booster pumps determine the main factors in deep water mud logging.In order to timely and accurately discover oil and gas and comprehensively monitor engineering to ensure the drilling safety in self deep water drilling in South China Sea,a combination of intelligent comprehensive mud logging system of geoNEXT,FLAIR fluid logging,a variety of oil detection and rock sample identification technique was used and has achieved good mud logging results.Based on self deep water mud logging practice of multiple wells,the authors expounded the developing trend in China:deep water mud logging should break the ground,make deep water mud logging while drilling and establish the integration of the wellsite and remote platform.
