绥靖油田杨19区块延9油藏东部具有埋藏浅,砂层厚,岩性单一,边底水有限的特征,是以构造为主的岩性—构造油藏。前期利用自然能量开发,地层能量下降迅速,为了实现油田稳产、高产,提高油田最终采收率,自2009年9月起对油藏进行注水开发,开发过程不断探索、不断精细注采调整,目前已取得良好效果,并在调整过程总结了一些经验,对西部油藏开发提供了理论上的依据。

The east area of Yan 9 reservoir in Yang19 block in Sui Jing oilfield is the lithology-tectonic oil reservoir based on the structure,with characteristics of shallow bury,thick layer of sand,single rock,and the limited water at the edge of bottom.At the early stage,natural energy was used in the development,but the energy of formation dropped rapidly.In order to realize the stable and high production of oilfield,and enhance the final oil recovery of oilfields,water-flooding development for oil reservoir has been carried out since Sept.2009.With the process being explored continuously and the precise water injection production being adjusted constantly,the better effect has been achieved now.Meanwhile,some experiences are summarized in the adjustment,which provides theoretical basis for western oil reservoir development.
