摘要
“十三五”期间,油气勘探开发向深层、超深层、非常规新领域发展,面临复杂的地质条件、恶劣的井筒状况等多重挑战,油气安全开发对井控工艺、装备及人员素质提出了更高的要求。为进一步减少溢流,以中国石油集团川庆钻探工程有限公司为例,系统分析了溢流防控难点,通过“全过程压实井控管理、全流程完善井控工艺、全面升级井控装备、全方位推进信息化建设、全面提升应急能力,有针对性的制定了“管理、工艺、装备、信息化、应急”五个方面的措施。结论认为:(1)深层、超深层油气勘探中的井控风险仍然严峻,深入开展地质工程一体化融合,是提高地层压力预测精度、降低溢流风险的重要举措;(2)数字化、信息化是溢流防控的重要发展方向,需加快推广应用;(3)井控装备的升级迭代是防范化解深井超深井井控风险的重要保障,井控装备逐步向自动化、智能化迈进是未来发展的重要趋势;(4)专业井控人才是溢流防控的关键,需持续培养“管理+现场”专业井控人才,注重班组和基层队伍的能岗匹配和能力提升。
Oil and gas exploitation during the 13th Five-Year Plan was confronted with challenges of complex geological conditions and terrible wellbore situations as it advanced towards some fresh domains of deep to ultra deep or unconven⁃tional reservoirs.Secure development puts forward higher requirements for all process,equipment and staffs of well control.So,taken PetroChina Chuanqing Drilling Engineering Company Limited as an example,some difficulties to prevent and control overflow were figured out.Then,countermeasures were made exclusively from five aspects of management,process,equipment,informatization and emergency response through"densifying all-around well control management,perfecting control technologies,upgrading control equipment,boosting overall informatization,and enhancing emergency response abili⁃ty".Results show that(i)there exist profound control risks in the exploration of deep to ultra-deep petroleum,and the ge⁃ology and engineering integration in depth is a fundamental measure to increase the accuracy to predict reservoir pressure while decrease overflow risks;(ii)the digital and information-oriented overflow prevention and control,as an essential de⁃velopment tendency,shall be expedited;(iii)both upgrading and iteration of the control equipment are able to ensure this prevention and keep away from certain risks in those deep to ultra-deep wells,and the gradual equipment automation and intelligentization is critical in the future;and(iv)professional control personals are the key to prevent and control overflow,and it is necessary to cultivate"management+on site"individuals in a row,and stress the post-skill assembly and ability promotion of base teams.
