我国致密气开发技术现状及未来发展定位

Exploitation Technique of Tight Gas in China and its Development Orientation

总结了致密气开发关键技术,即储层评价技术、气藏描述技术、优化布井技术、储层压裂技术、钻井完井技术、控水排水技术等;阐述了我国致密气开发面临的挑战及未来发展战略定位,指出应加强技术攻关,提高储量的动用程度和单井产量,加大政策扶持力度,优先开发,重点开发,进一步加快这一现实性最好的非常规天然气的开发进程。

We summarize the key technologies of tight gas exploitation,which include reservoir evaluation technology,gas reservoir description technology,well spacing optimization technology,reservoir fracturing technology,drilling and completion technology,water control and drainage technology. We outline the challenge and development strategy for tight gas exploitation. It was pointed out that the technique research should be boosted to increase reserves producing degree and single-well yield; policy supports should be intensified to accelerate development of tight gas,which is the unconventional natural gas with the best reality.
