Complex Fault Block Reservoir In Jiangsu Oilfield Water Flooding Development Effect Evaluation

In the paper, Jiangsu Oilfield complex faulted block reservoirs(the GaoJi Oilfield) is the main object of study. The writer worked out a complete system of complex fault block oil reservoir water flooding effect evaluation based on the characteristics of the complex faulted block reservoirs. On the basis of the system of fuzzy mathematics theory, have done a comprehensive evaluation of the effect of the Jiangsu complex faulted block reservoirs by fuzzy comprehensive evaluation theory.In this paper, Jiangsu Oilfield complex faulted block reservoirs from the following aspects:1. Evaluation index system in this article is the systematic study of the early reservoir water flooding to the development of comprehensive evaluation index system on the basis of its wheat from the chaff and leaving some indicators worth learning,removing some not suitable for complex faulted reservoir development evaluation indicators, and some not suitable complex faulted reservoir development evaluation indicators, and some new evaluation indicators for complex faulted block reservoirs water flooding effect。2. The paper is that broke through the prestandard classification methods were evaluated from the two major aspects of the oil displacement efficiency and sweep efficiency of water flooding effect, than early in the reservoir waterflooding comprehensive evaluation method is more suitable for complex fault block oil in Jiangsu.3. Developed a comprehensive evaluation of the development effect of various indicators.4. Research to develop the evaluation criteria for the various indicators for complex fault block oil field development.Committed to the practical application of the simple and accurate in the index calculation method of indicators the development of standards not only by a reasonable inspection methods are examined, and wide consultation, Southwest Petroleum University and Jiangsu Oilfield Exploration and Development Institute expert advice. And ultimately the formation of a scientific and reasonable standard suitable for the comprehensive evaluation of the complex faulted block reservoirs.
