辽河高成熟探区持续勘探发现技术及应用

Continuous Exploration and Discovery Technology and Its Application in Liaohe High Mature Exploration Area

历经50多年勘探,辽河探区整体进入高成熟勘探阶段,老区如何持续获得勘探新发现,是解决资源接替矛盾的首要问题。“十三五”期间,以老资料重建为基础,以“两宽一高”等新技术为手段,以构建新的油气藏模型为核心,对辽河探区各凹陷开展“整体认识、整体评价、整体部署”全方位勘探,发现了陡坡带砾岩体油藏、深层超压火成岩油藏、洼陷中心页岩油藏、残留型中生界潜山油藏、中浅层复杂断块油气藏五大勘探领域,落实了1个亿吨级、8个千万吨级规模储量区带。“十三五”勘探实践证明,解放思想、坚定信心、突破理论、优化技术,高成熟探区勘探仍大有可为。

After more than 50 years of exploration,Liaohe Exploration Area has entered the stage of high maturity exploration as a whole.How to obtain new exploration discoveries continuously in the Old Area is the primary problem to solve the contradiction of resource substitution.During the 13th Five-year Plan,based on the reconstruction of old data and by taking the building of a new oil-gas reservoir model as the core,the reconstruction of old data as the basis and the new technology of“wide azimuth,wide band,high density”as the means,we have carried out“overall understanding,overall evaluation and overall deployment”for each depression of Liaohe Exploration Area,found five exploration fields,namely conglomerate reservoir in steep slope zone,deep overpressure igneous reservoir,shale reservoir in the central depression,residual Mesozoic buried hill reservoir and middle and shallow complex fault block reservoir,and put one 100 million-tonnage reserve zone and eight 10 million-tonnage reserve zones in place.The exploration practice during the 13th Five-year Plan shows that there is still great potential for exploration in the old areas rich in oil and gas by freeing the minds,proceeding with confidence,breaking through theory and optimizing technology.
