地质储量品质评价技术推动海上油田开发

Technology of Quality Evaluation of Geological Reserves to Promote Offshore Oil Field Development

摘要: 针对海上油田勘探高成本，钻探的探井和评价井少、资料有限，地质不确性较大，不同海域对地质储量分析程度不一，形成海上油田地质储量品质评价技术方法，以分析地质储量分布特征、探明储量单元的品质类型及其规模、控制储量单元可靠性序列等，为油田开发动用地质储量的确定、井网部署、工程设施布置、钻井顺序等提供基础和保障。应用效果表明，地质储量品质评价方法，不仅统一了工作思路、方法和要求，而且对科学编制开发方案、有效规避风险投资，高效开发中国近海油田等具有重要的意义。

Abstract: In view of the high cost of offshore oil field exploration, the exploration wells and evaluation wells are few and the data are limited, and the geological uncertainty is very great. The method for evaluating the quality of geological reserves for offshore oilfields is proposed, which analyzes the geological reserves distribution, quality type and scale of proven geological reserves, reliability sequence of probable geological reserves. It provides the basis for oilfield development to deter-mine development and utilization of geological reserves, well pattern deployment, engineering fa-cilities layout, drilling sequence. The application results show that the technology of quality eval-uation of geological reserves, not only unifies the work ideas, methods and requirements, but also plays an important role in scientific development plan, effective risk averse investment, and effi-cient development of offshore oilfields in China etc.
