世界低渗透油气田开发技术现状与展望

Current situation and prospects of development technology for low permeability oil and gas fields in the world

低渗透油气田开发成熟技术有注水、压裂、注气等,储层精细描述和保护油气层是开发关键。多分支井技术、地震裂缝成像和裂缝诊断技术、新型压裂技术、注气提高采收率等新技术快速发展,发达国家低渗透油气田勘探开发技术日趋成熟。通过对世界低渗透油气田勘探开发现状进行研究,可实现低渗透油气资源优化利用,改善勘探开发效果,为低渗透油气田的高水平、高效益勘探开发和可持续发展提供理论及实践依据。

Matured technology for developing low permeability oil and gas fields includes water injection, fracturing and gas injection, etc. Fine reservoir description and protection are critical to reservoir development. The development of new technology for low permeability reservoir exploration and development is fast and gradually matured, including multi-lateral well, seismic fracture image and diagnosis, new fracturing technique, and gas injection. The study of the current situation of exploration and development for low permeability oil and gas fields in the world is helpful to optimal utilization of such resources, improving exploration and development result, and providing theoretical and practical basis for high level, high benefit, sustainable development of low permeability oil and gas fields.
