辽河断陷源内油气资源潜力分析

Oil and Gas Resource Potential Analysis within Kitchen in Liaohe Rift

辽河油田经过50余年以寻找圈闭为主的源外油气勘探开发,取得了丰富的成果。1986年突破年产原油10.0 Mt大关,成为中国第三大油田。进入21世纪以来,油田产量逐年下降,稳产难度越来越大。为了确保油田持续稳定发展,积极拓展勘探视野,寻找新的后备勘探领域,提出了油田发展的巨大潜在资源——源内油气资源的勘探新思路。可望带来新一轮油气储量和产量增长高峰。源内油气资源是相对于源外油气资源的概念而提出的。源内油气资源就是滞留在烃源岩中尚未排出或难于排出的油气资源。在长期的源外石油勘探工作中,摸索、总结了一套具有指导意义的石油地质理论和较成熟的勘探、开发技术系列,有效地勘探开发了地下的油气资源。源内石油勘探,是对油田发展和国家能源战略安全的前瞻性思考。但这是一个难度较大、常人难以理解的新领域和新观念!特别是面对目前世界原油价格不断下滑的困难局面,更增加了工作的难度。如能突破对这种新观念的种种束缚和来自方方面面的阻力,积极组织研究源内油气资源的富集和分布规律,开展相应的勘探开发技术攻关,将会带来新一轮油气资源量和储量增长高峰。对油田发展和国家能源战略安全具有重要的现实意义和深远的历史意义。

Obiectives：Through over 50 years of outside source rock development and exploration that primarily focus on trap finding,abundant results have been obtained.By the year 1986,the annual oil production of the oil field broke though 1000 ×10^4 t,and became the third largest oil field of China.While entering 21st century,oil production of this oilfield decreased year by year,and the difficulty of stabilizing oil production became larger and larger.The purpose of writing this paper is expanding exploration visibility to find new substitute exploration territory for the sustained stable development of the oilfield. Methods：A new bold exploration thinking of finding great tremendous potential resources potential resources in the source rock was raised. Results：The so called source rock hydrocarbon resources is the concept raised in comparison with hydrocarbon resources out side source rock.Source rock hydrocarbon resources is the hydrocarbon resources that is not yet expulsed or difficultly expulsed and still residual in the oil generative assemblage（hydrocarbon mother rock）. Conclusions：Outside source rock exploration （conventional oil conventional oil prospect）is the exploratory work primarily on finding oil and gas bearing trap.In the long term production operation,a set of directive petroleum geology theory and relatively matured serial exploration and development technique were found and generalized.With such exploration method,hydrocarbon resources of this oilfield were effectively explored , developed and used.Source rock petroleum exploration is a forward looking concept for oil field development and state energy resources strategy security.However,it is a hard understanding frontier and concept for average man. In particular ,the continuous gliding international crude oil price quagmire adds the difficulties to the exploration work.If we can break through many restrains and resistance to this new concept,and actively carry out studies on source rock hydrocarbon resources concentration and distribution and on relevant exploration and development technique ,the source rock exploration work will lead to a new hydrocarbon resources and reserve additions peak.
