Ying11Fault Block Dongxin Oilfield Fine Reservoir Research And Development Effect Evaluation

Ying11fault block is located in Dongying southwest structure in Central, the main oil-bearing series is S3lower,the oil reservoir is of low permeability lithologic reservoirs The study focused on the oil-bearing strata in the S3reservoir is a slump turbidite deposition.According to the production practice of Ying11fault block in exposed contradiction, injection-production network is not perfect, development difficulty is great, comprehensive adjustment effect is not obvious problem, through in Dongxin oil field Ying11in S3reservoir layers under multiple hierarchy subdivision and correlation, sedimentary microfacies and sand body distribution of micro and small the fine structure description, clarify the reservoir distribution, for tapping the potential of remaining oil and fault block adjustment to provide strong support, for enhanced oil recovery, improve fault block development level, keeping the old oil field is of great importance.The plane partition mining characteristics and development evaluation of the effect of mining characteristics, which is divided into:liquid producing ability of oil production, water absorption capacity, water cut rising regular pattern and other aspects; development effect is divided into:well pattern, energy state, reserves, water flooding, the fracturing effect and recovery evaluation etc.. This block Shasanzhong sand body in the integral analysis of anatomy, in order to solve the fault block oilfield development process major problems, how to more reasonable, effective exploitation of this kind of reservoir has a more profound understanding of.
