Abstract


Horizontal well technology has been mature conventional development techniques and stimulation means , but in the ultra-low permeability reservoir development , application range and scale more limited , according to the papers in the research use of horizontal well at home and abroad to develop low permeability sandstone reservoir based on the combination of Daqing peripheral development block horizontal well development of practical , on the basis of a comprehensive analysis of the ultra-low permeability reservoir wells network adaptability and development problems , through the application of reservoir engineering technologies and new progress of special low permeability reservoir drive system and reasonable well pattern , combined with numerical simulation , the principle of economic evaluation , optimization design that suits Daqing peripheral low permeability reservoir horizontal well arranged . Especially in the analysis of reservoir sensitivity and non-Darcy flow characteristics of the effect of water injection development on the basis of given additional start pressure and reservoir damage effects of horizontal wells and water absorption capacity prediction method to predict the horizontal well injection after pressure recovery on the development effectiveness of reasonable water injection system of development work and a better application block of East 141 Yushulin Oil , Daqing peripheral ultra-low permeability reservoir development adjustment and effective development to provide a new development model and reference . Daqing peripheral suitable for drilling horizontal wells block selection principle , preferably Yushulin Oil ultra-low permeability of Fuyang reservoir block of East 141 as a the research test block . Development effect of trace analysis . The results show that , in accordance with the most optimal combination of heral low , the effect of the deployment of ultra-low permeability reservoir horizontal well .
