准噶尔盆地油气资源潜力与中国石化常规—非常规油气一体化勘探策略

Resource potential in Junggar Basin and SINOPEC’s integrated exploration strategy for conventional and unconventional petroleum

准噶尔盆地油气资源丰富,勘探潜力巨大,是我国油气增储上产的主战场之一。近年来中国石油在准噶尔盆地勘探不断取得重大突破,揭示了常规、非常规油气有序共生的分布格局。为进一步吸收邻区油气成果勘探开发经验和地质理论新认识,制定中国石化在准噶尔盆地的油气勘探策略,文章系统分析了准噶尔盆地油气资源潜力及分布特征,指出了目前资源评价中存在的对天然气和非常规油气资源不够重视的问题;通过梳理近年来盆地在多领域、多层系、多类型的重大油气勘探突破,结合中国石化矿权区油气地质条件和勘探实际,提出中国石化下一步在准噶尔盆地的重点突破方向及勘探策略。研究表明,准噶尔盆地目前已进入中下组合勘探为主的新时期,勘探思路也必须随之调整,必须坚持由早期的源外勘探转为源内及近(进)源勘探,由早期的常规油气勘探为主,转为常规—非常规油气并重;并就下一步如何尽快实现中国石化在准噶尔盆地的大突破、大发现和增储上产目标,提出进一步摸清资源家底、组建常规—非常规一体化攻关团队、加强地质—工程一体化联合攻关和加大风险勘探力度等4个方面的勘探策略。

The Junggar Basin is rich in oil and gas resources,with huge exploration potential,which is one of the main arenas of increasing oil and gas reserve and producing in China.In recent years,CNPC has made major breakthroughs in exploration in the Junggar Basin,revealing the orderly symbionic distribution pattern of conven-tional and conventional oil and gas.In order to further learn from the oil and gas achievements and exploration and development experience in neighboring areas and the new geological theories,for formulating SINOPEC’s oil and gas exploration strategy in the Junggar Basin,the potential and distribution characteristics of the oil and gas resources in the Junggar Basin are systematically analyzed in this paper and it is pointed out that no enough atten-tion is paid to natural gas and unconventional petroleum.The key breakthrough direction and exploration strategy of SINOPEC in the Junggar Basin are put forward in the paper after reviewing the major exploration breakthroughs in multiple fields,multiple strata,and multiple types in recent years and combining with the oil and gas geolo-gical conditions and exploration practice of SINOPEC’s mining rights area.The research reveals that the Junggar Basin has entered a new period of exploration dominated by the middle and lower assemblage,and the explora-tion ideas must be adjusted accordingly.We must insist on the transformation from early outside-source explora-tion to intra-source and near-source exploration,and from early conventional petroleum exploration to both convention-al and unconventional petroleum exploration.In order to make big exploration breakthrough of SINOPEC and realize the target of increasing reserves and production in the near and medium term in the Junggar Basin as soon as possible,four exploration strategies are proposed in the paper,including further figuring out the resources,establishing an integrated research team of conventional and unconventional petroleum,strengthening the joint research of geological and engineering integration,and increasing the support of risk exploration.
