| Jiyuan tableland oilfield chang6reservoir to lithologic reservoir is given priority to, for the new development series of strata, good oil shows, broad prospects. Skeleton from the current development well and well effect, chang6reservoir belongs to low porosity low permeability type, vertical heterogeneity is strong, frequent change of lateral; Development experimental zone in the early production quickly, the next step development goals are not clear. In order to investigate chang6reservoir sand body distribution characteristics and accumulation, to carry out the favorable target area evaluation, determine reasonable development technical policies, development of lay the foundation for chang6reservoir effectively.Based on her tableland oilfield in geological data and development experiment, production performance and dynamic monitoring data collection and sorting, based on the clear chang6reservoir sand body distribution characteristics and accumulation, to carry out the favorable target area; For single well, well group and the dynamic analysis of reservoir development, the research on water injection effect, find out the well production capacity, production decline and water absorption performance and water cut rising status and direction of water; The reservoir geological conditions and the status of the development technology to perform control action of development effect; Analysis of water use, water flooding reserves producing condition, to determine the reasonable development technical policies, to expand the scale of chang6reservoir development and effective development lay the foundation. |
