中国石油“十三五”物探技术进展及“十四五”发展方向思考

Geophysical prospecting technology progress of PetroChina in the 13^(th) Five-Year Plan period and development direction consideration in the 14^(th) Five-Year Plan period

“十三五”期间,中国石油天然气股份有限公司(简称中国石油)根据日益复杂的油气勘探开发对象,分盆地、分领域制定物探技术政策,强化地震采集源头设计,严格过程管控,确保部署成效;开展老资料精细处理解释,挖掘资料潜力,瞄准生产瓶颈难题,强化科研攻关,提高解疑能力;强化分盆地、分领域技术研讨交流,加强物探地质复合型人才培养,提升人才素质和技术应用水平;强化基础工作,实施精益管理,促进有序稳健发展;发展完善了6类物探技术系列,形成19项关键技术,有力支撑了中国石油原油产量稳中有升、天然气业务快速发展。“十四五”油气勘探开发重心不断向深层—超深层、页岩油气,以及强复杂地表更复杂领域转移,提高难动用储量开发成效、提高老油气田采收率也面临技术挑战。为了满足新形势下油气勘探开发需求,针对八大重点领域,中国石油将按照集成推广、科研攻关、试验探索3个层次,发展高效、低成本、高精度物探技术,重点发展智能物探、深层地球物理勘探、油藏地球物理、井中地震等全新一代物探技术。

In 13^(th)Five-Year Plan period,PetroChina has made geophysical prospecting technology strategies for each oil basin and exploration domain according to the increasingly complicated exploration and development objectives.Seismic acquisition design was focused from the very beginning and process management was emphasized to ensure effective deployment.Fine processing and interpretation of existing seismic data were conducted to exploit potentials of the data.Aiming at bottleneck issues in production,scientific research was strengthened to improve problem-solving abilities.Technical discussions and workshops for individual basin and domain were encouraged,and training for interdisciplinary-talent of geophysics and geology was performed to enhance the quality of talent team and the level of technological application.The fundamental works were highlighted and lean management was implemented to facilitate a robust development.As a result,six categories of geophysical prospecting technology series have been developed and improved and 19 key technologies formed to strongly support the steady growth of oil production and rapid development of natural gas business of PetroChina.In the 14^(th)Five-Year Plan period,the focus of petroleum exploration and development will be continuously shifted to the deep/ultra-deep formations,shale oil&gas,very complex surface areas and more complicated domains.In addition,technology will face challenges in improving development effect of difficult-to-produce reserves and enhancing recovery of mature oilfields.To meet the demands of petroleum exploration development in the new environment,PetroChina will develop high-efficiency,low-cost and high-precision geophysical technology according to three levels of integrated promotion,scientific research,experiments and pilot test in the eight key domains,and give priority to new generation geophysical prospecting technologies,such as intelligent,deep-layer geophysical prospecting technology,reservoir geophysics and borehole seismic.
