摘要/Abstract

摘要： 苏里格气田勘探发现以后效益开发面临极大挑战，为吸收借鉴国际先进的开发技术和管理经验实现开发突破，确立了与法国道达尔公司共同开发、中方担任作业者的国际合作开发模式。10余年的合作开发实践表明，在相同的储层地质条件下国际合作区单井开发指标明显高于自主开发区，系统梳理关键开发技术并进行系统总结对提升自主开发区开发效果具有重要意义。与自主开发区追求规模效益与低成本控制的开发理念不同，国际合作区以经济效益、正现金流策略为目标，以风险控制为核心。经过多年集中攻关与实践检验，形成了三维地震—地质融合储层评价、网格分区棋盘丛式标准化井网部署、批量实施工厂化钻完井作业、TAP Lite分层压裂储层改造、适度放压间歇生产气井管理、速度管柱主导的措施增产6项关键核心特色开发技术，通过与自主开发区技术对比，落实了5项可供借鉴的特色开发技术，并总结了3条重要启示：（1）持续深化地质研究支撑高质量部署；（2）加强顶层优化设计支撑科学有序实施；（3）强化全过程管理与质量控制助推开发效果提升。国际合作区关键核心开发技术与重要经验的吸收借鉴可对致密气新区开发效果的提升提供有力支撑。

Abstract: The benefit development of Sulige Gasfield faced great challenges after its discovery. In order to learn from international advanced technologies and management thoughts, an international cooperative development mode has been established between Total and PetroChina (operator) to achieve development breakthroughs. More than 10 years’ international cooperative practice shows that, the production performance of a single well in international cooperation zone is significantly better than that in self-operated development zone given the same reservoir geological conditions. Therefore, it is of great significance to systematically summarize the development technologies to improve the development effect in self-operated development zones. Different from the development concept of pursuing large-scale benefits and cost control in self-operated development zones, the economic benefits and positive cash flow are targeted and risk control is centered in international cooperation zone. In addition, six main development technologies have been formed by research and practical tests for several years, including 3D seismic-geological fusion reservoir evaluation, grid partition and checkerboard cluster well pattern deployment, well factory drilling and completion operation, TAP Lite layered fracturing reservoir reconstruction, moderate pressure relief and intermittent gas production well management, and speed string measures for production increase. By comparing development technologies applied in self-operated zones, five key development technologies are determined to be referred and three important enlightenments are concluded: (1) Continuously deepen geological study to support high-quality deployment; (2) Strengthen the top-level optimization design to support scientific and orderly implementation; (3) Strengthen the whole process management and quality control to boost the development results. The absorption and reference of key development technologies and important experience in international cooperation zone provide strong support for the improvement of development effect in new tight gas zones.
