不同类型油藏水平井部署及配套技术研究

针对厚层特稠油油藏汽驱井组蒸汽超覆严重、厚层底水普通稠油油藏底水快速突进、薄层边水特稠油油藏油水关系复杂、薄层特稠油油藏边部储量难以有效动用、火山岩裂缝性底水稀油油藏底水突进严重5类不同类型油藏中存在的开发矛盾,以精细地质研究为基础,以水平井技术为依托开展对老油田挖潜。共部署了71口水平井,实施55口,取得了良好的开发效果和可观的经济效益,增加地质储量326.66×104t,预计提高采收率7%以上,为老油田＂二次开发、深度开发、多元开发＂开辟了一条新路。

Study on different types of horizontal well matching technology for deploying and support

Thick layer of heavy oil reservoirs for special group steam steam drive well overlap seriously,the thick layer of heavy oil reservoirs with bottom water of ordinary rapid penetration into the bottom water,thin water boundary between the water especially heavy oil complex,particularly thin heavy oil hidden reserves can not effectively use the edge,rocks fractured oil reservoirs with bottom water and bottom water penetration into the serious category 5 different types of contradictions in the development of existing reservoirs in order to fine geological research-based,relying on horizontal well technology to carry out the old oil fields Potential.Deployed a total of 71 horizontal wells,the implementation of 55,achieved good results and considerable economic development,increase reserves 326.66×104t,enhanced oil recovery is expected to more than 7% for the old oil fields,＂secondary development,further development,Multi Development ＂opened up a new path.
