Chang4+5, Chang6of Puziwan South Reservoir Layer Injection Test And Effect Evaluation

The majority of our oil fields have been developed into the water Currently, but serious reservoir heterogeneity, reservoir complex structure, the nature of crude oil less, making high permeability and low permeability layers are not effective water level, water flooding spread coefficient and recovery can not be effectively increased, thus affecting the overall development of oil field effect. In this paper, Puziwan Chang4+5, Chang6reservoir characteristics of the material, the penetration rate of superimposed zone heterogeneity of very detailed research evaluation; by water injection wells on the test data to analyze the situation and come up with non-penetration homogeneous absorption profile with the link between non-uniformity in order to determine sub-surface injection and injection wells correspondence; test area wells for single production, co-layer mining to evaluate the effect of increasing oil production, and production method different layers the high moisture content under the wells of water channeling analysis; final drive control water level, water drive with the degree of water in the rate of individual indicators to mining, evaluation of the effects of co-layer mining for Puziwan Chang4+5, Chang6follow-up of the water reservoir to provide technical basis for development.
