中文摘要:

对油井或开发井组进行开发效果评价是油田开发管理一项常规的工作。常规油田开发指标评价方法,仅考虑递减率、含水上升率、存水率,水驱指数等单因素指标,缺乏综合评价结果,定性分析多,且有一定的人为影响。为了进一步提高海上油田管理水平,改善油田开发效果,本文尝试利用属性数学理论将多目标评价问题转化成单一目标评价,提出了海上油田开发效果合理评估方法。渤海Y油田应用结果表明,该方法合理可行、易操作。结合各井组开评价结果,建立了渤海Y油田合理采油速度、提液时机、阶段注采比等油藏管理指标模板,对实现海上油田科学、合理的油藏精细管理,具有一定指导意义。

英文摘要:

In order to improve the management level of offshore oil field and the effect of oil field development, we need to reasonably evaluate the effect of the development of the well group of oil field. Conventional oil field development index evaluation method, only consider the decline rate, water cut rising rate, water storage rate, water drive index and other factors. This is a lack of comprehensive evaluation results, and there are more qualitative analysis and human influence. In this paper, we use the theory of attribute mathematical theory to transform the multi-objective evaluation into the single objective evaluation, and propose the evaluation method of offshore oil field development effect. The application results of the Bohai Y oil field show that the method is reasonable and feasible, easy to operate. Combined with the evaluation results of each well group to set up the oil recovery rate, the time of extraction and the injection production ratio and other indicators of reservoir management template of the Bohai Y oil field. This has certain guiding significance for realizing the scientific and rational management of reservoir of the offshore oil field.
