摘要: 储量评价是海外油气田开发新项目资产价值评价的核心,决定了海外油气田开发新项目的投资收益和开发方案的制定。为合理快速评价海外新开发油气田储量,并为开发方案的制定提供基础地质模型,以地质建模为手段,建立海外新开发油气田储量评价方法和流程。基于地质建模的海外油气田开发新项目储量评价包括资料收集、地质格架评价、储层相和属性评价、储量计算与风险评价4大环节,可分为地质建模和储量评价2个阶段。地质建模阶段在资料收集的基础上,对最可能的构造、储层相和属性分布进行三维建模。储量评价阶段再依据对储层的不确定性的认识,开展地质格架、储层相和属性分布的不确定性研究,建立开发新项目的概率储量分布,暴露海外油气田开发新项目的储量风险,实现海外开发新项目储量的快速科学评价。基于地质建模的海外油气田开发新项目储量评价方法,有效融合了容积法和概率法的优点,应用实例表明该方法具有较好的实用性,可推广应用于海外油气田储量评价中。

Abstract:Reserve evaluation is the core of asset value evaluation of new investment projects in overseas oil and gas field development and determines the investment income and formulation of a development plan. A method of reserve evaluation was established by using geological modeling in order to reasonably and quickly evaluate the reserves of new investment projects in overseas oil and gas field development, and to provide a basic geological model for the formulation of a development plan. The evaluation consists of data collection, geological framework evaluation, reservoir facies and properties evaluation, and reserve calculation and risk assessment. It can be divided into two stages:geological modeling and reserve evaluation. The geological modeling stage includes three-dimensional modeling of the most probable structures, reservoir facies and properties based on data collection. In the reserve evaluation stage, the uncertainty of the geological framework, reservoir facies and properties are carried out based on the understanding of reservoir uncertainty, then the probabilistic reserve distribution is obtained and the risk of reserve is exposed. Finally, the rapid scientific reserve evaluation of the new investment projects of overseas oil and gas field development is realized. The reserve evaluation method for new investment projects of overseas oil and gas field development based on geological modeling effectively integrates the advantages of volume method and probability method, and the application example shows that the method is practical and can be applied to the reserve evaluation of overseas oil and gas fields.
