摘要:

气田开发效果评价在发现目前开发存在的主要问题、提高气田管理水平以及提出调整对策等方面发挥着重要作用。从产能、能量保持程度和井流物性质三方面出发,考虑采收率、地层压力保持程度、气油比年递增率等指标,提出了凝析气田开发效果定量评价方法。首先基于层次分析法、灰色关联法和RSR值综合评价法计算各指标权重,然后通过岭形分布函数和因子分析法确定各指标隶属度矩阵,最后经模糊变化及最优选择得出评价结果。YH23区块E+K气藏天然气采收率为82.95%,凝析油采收率为58.57%,地层压力保持程度为87.8%,计算可得开发效果评价矩阵 Y =[0.623 7,0.175 2,0.201 1],属于一类开发水平,经验证与该气田实际评价结果一致,证实提出的方法准确可靠,为气田进一步开发调整指明了方向。

Abstract:

The evaluation of gas field development effect plays an important role in discovering the main contradictions existing in the current development, improving the level of gas field management and putting forward adjustment countermeasures. In this paper, a quantitative evaluation method for the development effect of condensate gas field is proposed from the three aspects of productivity, energy retention degree and well logistics property, and considering the recovery factor and pressure retention degree, et al. Firstly, the weight of each index is calculated based on the analytic hierarchy process, grey correlation method and RSR value comprehensive evaluation method, and then the membership matrix of each index is determined through the ridge distribution function and factor analysis method. Finally, the evaluation results are obtained through fuzzy change and optimal selection. The natural gas recovery rate of E+K gas reservoir in YH23 block is 82.95%, the condensate recovery rate is 58.57%, and the formation pressure maintenance degree is 87.8%. The development effect evaluation matrix Y =[0.623 7, 0.175 2, 0.201 1] can be obtained through calculation, which belongs to the class I development level. After verification, it is consistent with the actual evaluation results of the gas field, which proves that the proposed method is accurate and reliable, and points out the direction for the further development and adjustment of the gas field.
