Application of fuzzy comprehensive evaluation method to assess effect of conformance control treatments on water-injection wells

Petroleum 2024年第1期10卷 165-174页

作者： hu Jia Pengwu Li Wei Lv Jianke Ren Chen Cheng rui Zhang Zhengjun Zhou Yanbin Liang State Key Laboratory of Oil and Gas Reservoir Geology and Exploitation Southwest Petroleum University Oil and Gas Technology Research Institute PetroChina Changqing Oilfield Company Oil Production Technology Institute of PetroChina Dagang Oilfield Company

As an effective method to prolong the life of mature field, conformance control in water-injection well has been used wildly. Naturally, effect evaluation of conformance control has attracted great attention because it is an important guideline for the design of later enhanced oil recovery(EOR) plan. Usually,production responses such as excessive water reduction and oil production increment are widely used as the indicators. However, production responses may be unreliable due to the difficulty in determining an effective injection well which is caused by a large number of treated water-injection wells in a well group. Therefore, with the application of fuzzy comprehension evaluation(FCE), five evaluation indexes(injection pressure, injectivity index, slope of hall curve, variation coefficient and homogenization coefficient of injection profile) describe injection responses were selected to establish a new evaluation method in this paper. Based on fuzzy mathematics, FCE reflects the difference of evaluation ***, weights of evaluation indexes were obtained by analytic hierarchy process(AHP), which made the results more convincing. Taking Bai 239 oilfield as an example, the five injection responses indexes were used to assess treatment effect on five water-injection wells by single index evaluation and FCE. The results showed that among the five evaluation indexes mentioned above, the slope of hall curve was the most important factor affected evaluation result. In single index evaluation, opposite results may be produced easily on account of the one-sidedness of single index or human error. Furthermore, we found that effective treatment was a relative concept actually. The result of FCE was consistent with single index evaluation but FCE was more acceptable. This study suggests that FCE could be applied to another field such as water flooding, acidizing and hydraulic fracturing
