摘要:

依托大量文献资料,以勘探认识突破、勘探思路转变、勘探技术进步为主线,精细剖析冀中坳陷油气勘探发展过程,将冀中坳陷油气勘探历程划分为区域地质普查勘探(1955—1972年)、突出潜山油藏勘探(1973—1985年)、主攻古近系—新近系构造油藏勘探(1986—1999年)和加强岩性-地层油藏及隐蔽型潜山油气藏勘探(2000—2019年)4个阶段,总结了每个阶段的勘探认识、勘探思路、勘探技术、勘探重大发现以及储量的增长特点等。在此基础上,提炼出的潜山油气成藏认识与成藏模式引领了潜山领域的多轮勘探与持续发现,油气分布“互补性”、“洼槽聚油”等理论有效指导了岩性-地层油藏的勘探与规模发现,“区带优选-圈闭落实-油藏发现”评价技术有力支撑了岩性-地层油藏勘探的部署优化,深化了陆相湖盆断陷油气勘探发现规律认识,对今后的油气勘探具有借鉴作用。

Abstract:

Based on a large number of literatures, this paper analyzes the exploration history in the Jizhong depression with the breakthrough of exploration understanding, transformation of exploration ideas and advancement of exploration technologies as the main line. The oil and gas exploration process of the Jizhong depression is divided into four stages:regional geological reconnaissance and exploration (1955-1972); exploration focusing on ancient buried-hill oil reservoirs (1973-1985); exploration mainly attacking the Palaeogene-Neogene structural oil reservoirs (1986-1999) and exploration of lithostratigraphic oil reservoirs and subtle buried-hill oil and gas reservoirs (2000-2019). This paper summarizes the exploration understanding, exploration ideas, exploration technologies, major exploration discoveries and reserves growth characteristics of each exploration stage. Based on which, Huabei oilfield has refined the new theoretical understanding and reservoir-forming model of buried-hill oil and gas reservoirs, and led multiple rounds of exploration and sustained discoveries in the field of buried hill through continuous innovation. The new theories of “complementarity” of oil and gas distribution and “oil accumulation in sags and troughs” effectively guide the active exploration and large-scale discoveries of lithostratigraphic oil reservoirs. The evaluation method of “play optimization-trap delineation-reservoir discovery” has effectively promoted the exploration deployment optimization of lithostratigraphic oil reservoirs. These exploration implications have deepened the understandings of oil and gas exploration and discovery in continental lacustrine fault depressions, which has important reference and guiding significance for China’s oil and gas exploration in the future.
