| 海上油田开发方案编制阶段基础资料尤其是探井与评价井资料较少，基于有限的资料形成的油田地质储量认识存在一定的局限性和不确定性，进而影响开发方案的合理性和灵活性。基于100多个海上油田的地质储量相关研究工作，建立了地质储量品质评价“三步法”：以地质储量规模、流体性质和储层物性为主要评价参数，分析油田地质储量分布特征；应用单因素与多因素相结合的分析方法对探明地质储量进行综合储量品质分类，筛选出探明优质地质储量；按计算方法对控制地质储量进行分类，综合控制地质储量的认识程度及与评价井的距离，分析控制地质储量的可靠性，量化可供开发动用的控制地质储量。以渤海L油田为例，介绍了地质储量品质评价方法的实际应用效果，表明通过油田地质储量品质评价可以确定油田开发动用储量，有效提高油田开发方案应对风险的能力。 |

| Abstract: |
| In the preparation of oil field development plans, there is limited basic research data, especially exploration and evaluation well data for offshore oil fields. The understanding of oil field geological reserves based on limited data will inevitably have certain limitations and uncertainties, which will affect the rationality and flexibility of the development plan. Through research on geological reserves in over 100 offshore oil fields, a three-step method for evaluating the quality of geological reserves has been proposed. Firstly, the distribution characteristics of geological reserves were analyzed based on the scale of geological reserves, fluid properties and reservoir physical properties. Secondly, single factor and multi-factor analysis methods were used to classify the proved geological reserves and screen the high-quality proved geological reserves. The third was to classify the controlled geological reserves according to the calculation method, analyze the reliability of the controlled geological reserves according to the understanding of the controlled geological reserves and the distance from the evaluation well, and quantify the controlled geological reserves that can be developed and used. Taking oil field L of Bohai Sea as an example, this paper introduces the practical effect of geological reserve quality evaluation method, which shows that the reserves of oil field development can be determined by geological reserve quality evaluation, and the ability of oil field development plan to deal with risks can be effectively improved. |
