摘要: 胜坨油田是渤海湾盆地乃至中国东部陆相断陷盆地最大的整装油田。自1963年勘探发现以来,经历了勘探初期的快速探明、快速建产;勘探中期的高速开发、高产稳产;勘探后期的理论技术创新拓展勘探领域、高含水油藏精细开发技术攻关提升采收率,保持油田产量缓慢递减等阶段,每个阶段均有储量增长。至2018年底,勘探开发历程已达50余年,累计探明石油地质储量5.12×108t,累计生产原油1.93×108t,2018年末仍稳产150.00×104t以上。丰富的油气源条件,紧靠油源的大型背斜构造背景,多种类型储层、圈闭及有利的油气运移通道构成了胜坨油田优越的成藏条件。早期注水开发,高含水期精细油藏描述、层系细分与井网油藏矢量调整、韵律层细分挖潜等精细开发技术以及高勘探程度阶段油田主体周缘砂砾岩、浊积岩油藏勘探技术的不断进步,为胜坨油田持续增储及长期高产、稳产提供了有效支撑。

Abstract: Shengtuo oilfield is the largest monoblock oilfield in the Bohai Bay Basin and even in the continental fault basins of eastern China. Since discovered in 1963, it has experienced rapid reserve discovery and production in the early exploration stage, high-speed exploitation and high and stable production in the middle exploration stage, as well as theoretical and technological innovations for expanding the exploration fields and a breakthrough in the fine development technology of high-water-cut reservoir for enhancing oil recovery and slowing down decline of oil production in the late exploration stage. Reserves of this oilfield increase in each stage. By the end of 2018, throgh more than 50 years of exploration and development, Shengtuo oilfield has the cumulative proved oil reserves of 5.12×108t, and cumulative oil production of 1.93×108t; it maintained stable annual oil production of more than 150.00×104t in 2018. Abundant hydrocarbon resources, large anticline structure near to oil source, multiple types of reservoirs and traps, and favorable hydrocarbon migration channels provide excellent hydrocarbon accumulation conditions for Shengtuo oilfield. Fine development techniques such as water-flooding in the early development stage, fine reservoir description in the high water-cut stage, stratigraphic subdivision and well pattern vector adjustment, and fine potential tapping in rhythmic layers provide effective supports for continuous increase of reserves and long-term high and stable production of Shengtuo oilfield as well as continuous progress in exploration technologies for glutenite and turbidite reservoirs around the main body of the oilfield in the high-level exploration stage.

Key words: continental rift basin, hydrocarbon accumulation conditions, source-reservoir-caprock combinations, hydrocarbon migration channels, key technologies for exploration and development, Shengtuo oilfield, Bohai Bay Basin
