注采调控技术在吴仓堡长6油藏中的应用

鄂尔多斯盆地中生界开发层系均为低压油藏,注水开发是低渗透油藏提高采收率、提高开发效益的有效手段,是低渗透油藏实现长期稳产的根本保证。以控制吴仓堡地区长6低渗透油藏含水上升速度,减缓递减,实现长期稳产为目的,分析了精细注采调控技术在吴仓堡长6油藏的应用效果,并进一步对区内开发存在的问题和下步与开发相关的研究提出了建议。

Application of Injection and Control Technology in Wucangpu Block Chang 6 Reservoir

Development strata of the Paleozoic in the Ordos Basin are low-pressure reservoir, and water injection development is a low-permeability reservoir enhanced oil recovery and effective means to improve development effectiveness, and low permeability reservoir to achieve the fundamental guarantee of long-term stability. For Chang 6 low permeability reservoir of Wucangpu block, for the purpose of slowing down the water cut ascending velocity and the production decline rate, sustaining production for long term, this paper analyses the application result of accurate modification and con- trol technology of injection and production in Chang 6 reservoir of Wucangpu block. Further development exists in the region and the next step of development is recommended.
