摘要
从中外不同类型的致密油藏的定义和标准中总结出其特点,统计分析了国外致密油的资源量及分布状况。选取开发规模较大或开发技术成熟的致密油区为研究对象,从地质特征、开发历程及现状、技术发展状况、开发成本、开发效果及规律等多个角度进行分析,提升并总结出不同地质条件下的主要开发技术及其政策、单井初期产油量、递减率和成本等关键指标的变化规律。综合分析了中国石化致密油藏的地质特点和开发状况,得到以下认识:地质认识是致密油藏有效开发的基础,开发配套技术是致密油藏有效开发的保障,开发基础研究是致密油藏有效开发的关键,低成本战略是致密油藏有效开发的核心。
This paper summarizes the implication and characteristics of tight oil from different domestic and foreign tight oil definitions and criteria, and statistically analyzes foreign tight oil resources and their distribution. It selects tight oil-gas fields of large development scale or mature technology as the research subject, and analyzes them from different perspectives such as geological properties,development history and status, development status technology, cost of discovery and development, development effect and laws, etc. It concludes the major development technology and policies aiming at different geological conditions, and the variation law of key development indexes including initial production and decline rate. Combined with the tight oil development status and geological characteristics of Sinopec, this paper draws inspirations in terms of geology, technology, basic research, and cost, etc. All these recognitions will be of great reference and guiding significance to the development orientation, technology policy making, recognition of development law, scheme optimization, organization and operation, and management mode of domestic tight oil development technology.
