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 control 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.
