The Development Effect Evaluation And The Comprehensive Adjustment Study Of Oulituozi Oil Field

Most oil fields in China have all adopted the development method of waterflood pressure maintenance one after another. Due to the complexity of the reservoir geology situation, how to flood to achieve the optimal development effect is always the major concern. Therefore, making a scientific evaluation of the waterflood development effect has a profound effect for bettering reservoir waterflood development and EOR. What's more, it provides a solid evidence for implementing adjustment and tapping the latent power.This paper took the Oulituozi oil field as an example. By incorporating the production characteristics of different development periods and evaluating the waterflood development effect of this block, this paper analyzed the historical comprehensive adjustment effect, summarized the main features of the current movement of oil and water, and summed up the major factors that affect the waterflood development effect. Many methods such as reservoir performance comprehensive analysis and numerical reservoir simulation were used to conduct a research for the distribution law of the remaining oil. Potential blocks which are rich in remaining oil were found and the main factors that affect the distribution of remaining oil were summarized. What's more, the oilfield development program was made a comprehensive adjustment on the basis of the distribution situation of the remaining oil. A set of methods in view of the evaluation of the waterflood reservoir development effect and the comprehensive adjustment were acquired, which provides guidance in a sense for other waterflood development reservoirs.
