Research and application of development adjustment technology in conventional heavy oil reservoir——taking Gaoqian north area as the example

Conventional heavy oil reservoir formation has the problems of loose cementation,big crude oil viscosity,poor liquidity,easy sand production in oil wells during the production process,breakthrough of edge-bottom water and etc which seriously constraint the production rate and development efficiency.Aiming at the problems mentioned above,based on fine reservoir description and reservoir dynamic analysis,the infilling adjustment has been established to enhance reserves producing degree.Using the edge water profile control technology to inhibit the edge-bottom water breakthrough,horizontal well and sidetracking horizontal well technology to improve conventional oil production speed and oil recovery of heavy oil reservoir development adjustment.Therefore,good development effect has been achieved in practice.
