摘要
通过技术探索、研究试验、推广应用和新技术攻关,胜利油田发展形成了底水油藏、屋脊断块油藏、稠油油藏、地层不整合油藏及整装油藏特殊结构井地质油藏工程设计技术、钻井完井采油配套技术,形成了水平井、大位移水平井、分支水平井、鱼骨状分支水平井、老井侧钻水平井、老井侧钻定向井等井型。已在各类油藏181个开发单元完钻各类水平井586口,284个开发单元完钻老井侧钻定向井742口,年产油量分别达到119×104t和79×104t,累计产油已分别达到825×104t和409×104t。特殊结构井开发技术已成为胜利油田新、老区增产稳产的主导技术之一,近年来在薄层油藏、特高含水期厚层正韵律油藏、潜山特稠油油藏、特超稠油油藏、复杂断块油藏特殊结构井油藏描述、油藏工程优化设计、钻井工艺、完井工艺、采油工艺等方面取得了新进展,现场应用取得良好效果。
Shengli Oilfield has developed the reservoir engineering design and drilling-completion-production techniques of special structure drilling for reservoirs with bottom water, fault block, heavy oil, unconformity etc. , and drilled different types of wells including horizontal well, sidetracked well, extended reach well, multi-lateral horizontal well and so on. There are 586 different horizontal wells in 181 development units of different types, and 742 sidetracked wells in 284 development units. The annual oil production is 1.19 and 0.79 million tons, respectively, and the cumulative oil production 8.25 and 4. 09 million tons. The special structure drilling has become one of the dominant techniques for the stable production and production growth of the field. New advancements have been achieved in the reservoir description, reservoir engineering design, well drilling technology, well completion technology and producing technology for thin-layer reservoirs, high-watercut thickqayer positive rhythm reservoirs, buried hill heavy oil reservoirs, extra-heavy oil reservoirs, and complicated fault-block reservoirs.
