四川盆地侏罗系致密油勘探开发进展与对策

四川盆地侏罗系原油勘探开发历史悠久，“十二五”期间在致密油地质理论和现代勘探开发工艺等关键技术的指导下，系统开展了攻关研究，取得了多项新进展、新认识。但就目前的认识和勘探开发成效而言，仍处于致密油起步和探索阶段。要实现效益开发主要面临深化理论认识、突破关键技术、加大管理创新、科学有序推进等挑战。基于该区复杂的地质条件和不可预见的国际原油形势，要实现四川盆地侏罗系的效益开发，需加强资源优选，落实“甜点”；突出技术攻关，突破瓶颈；加大管理创新，降本增效；科学合理组织，有序推进。

Countermeasure and progress of exploration and development of Jurassic tight oil in the Sichuan Basin

The exploration and development of tight oil in the Jurassic has a long history in the Sichuan Basin. Many new developments and recognitions have been made during the 12th Five Year Plan based on tight oil geological theory and modern exploration and development techniques. However, tight oil exploration is still in beginning stages, facing the challenges of deepening theoretical knowledge, innovating key technology, improving management, and promoting development methodically. Due to complex geological conditions and the unforeseeable international crude oil supply situation, some advice was proposed to realize development efficiencies of the Jurassic tight oil in the Sichuan Basin. Target selection should be optimized to identify "sweet spots". New techniques are necessary for breaking bottlenecks. Improved management helps reduce costs. Scientific organizations can promote tight oil development systematically.
