科学探索井历程、成效及意义——纪念科学探索井项目实践30周年

History,achievements and significance of scientific exploration wells:For the 30^(th) anniversary of the “scientific exploration well” program

科学探索井项目(1986—2000年)开始实施至今已30年,回顾并总结其探索历程、勘探成效、管理经验等对指导陆上未来勘探的意义重大。科探井钻探的目的是立足勘探院(石油勘探开发科学研究院)地质研究新认识,在新盆地、新层系和新区开展科学探索,既解决重大基础地质问题,又追求突破发现。历经15年共钻井14口,其中台参1井、陕参1井发现了吐哈油田与靖边大气田,开启了西北侏罗系与鄂尔多斯盆地天然气大规模勘探的序幕,高科1井、酒参1井、沁参1井等获低产油气流,为日后获大发现打下基础,此外还储备了一批战略性领域和目标。在项目管理中,建立了"中国石油总部承担投资风险、以勘探院为主提出领域目标、油田承担钻探任务、勘探院监督"的运行模式,形成了"精雕细刻、精耕细作、深挖细找、点滴不漏"的管理细则,建立了科学合理的勘探程序。科学探索井的意义体现在将科研成果直接转化为生产力,引领并推动油气勘探取得战略性突破,并为中国石油实施风险勘探积累了宝贵经验。

Thirty years have past since the ＂scientific exploration well＂ program （1986-2000） was initiated in 1986. Review and summary of the exploration history, achievements and management experiences are significant for directing future onshore exploration. The program aimed to address critical and fundamental geological challenges and achieve breakthroughs through scientific exploration in new basins, new strata and new regions, on the basis of new geologic cognitions obtained by PetroChina Research Institute of Petrolenm Exploration ＆ Development （RIPED）. During 15 years of efforts, 14 wells were drilled, of which Well Taican 1 and Well Shaancan 1 contributed to the discovery of Tuha Oilfield and Jingbian giant gas field, opening the prelude to large-scale natural gas exploration in the Jurassic System in northwest China and the Ordos Basin. Several wells （e.g. Gaoke 1, Jiucan 1, and Qincan 1） produced low-yield oil and gas flows, laying the foundation for later large discoveries. Moreover, a series of strategic domains and targets have been ascertained. In program management, a scientific and rational exploration procedure has been established： the PetroChina headquarter assumes investment risks, RIPED proposes domains/targets, and oilfields undertake specific tasks under the supervision of RIPED, following the rules of ＂intensive and thorough explorations＂. The significance of the ＂scientific exploration well＂ program is manifested in transforming scientific achievements into productivity, guiding and driving oil and gas exploration to achieve strategic breakthroughs, and accumulating valuable experiences for PetroChina to carry out risk exploration.
