| Summary: | 鄂尔多斯盆地致密气主要分布在上古生界石炭—二叠系,致密气资源量10.37×1012m3,占盆地天然气总资源量的68%,1995年以来先后发现了米脂、乌审旗、大牛地、神木、苏里格5个致密大气田,致密气地质储量3.78×1012m3,目前已进入储量产量快速增长阶段,近5年来储量年均增幅超过5 000×108m3,致密气产量年均增幅30×108m3,建成了以苏里格气田为代表的致密气生产基地,集成创新形成了以全数字地震、优化钻井、储层改造、井下节流、排水采气、数字管理等为核心的致密气勘探开发关键技术,转变发展方式形成了以＂标准化设计、模块化建设、数字化管理、市场化运作＂为重点的致密气田开发模式,2011年苏里格气田生产致密气137×108m3,成功地向北京、上海、西安、银川、呼和浩特等重点城市供气。综合评价认为：苏里格南部、靖边—高桥、神木—米脂、盆地西南部是近期致密气增储上产的主要地区,预计2015年以前,盆地致密气储量规模将超过4.5×1012m3,致密气产量将达到255×108m3,并持续长时间稳产。 |

| Bibliography: | Tight gas of the Ordos Basin is mainly distributed in the Upper Paleozoic Permo-Carboniferous source rocks, tight gas resources reaching 10.37 x 1012 m3 ,among which natural gas resources occupy 68 %. Since 1995, five large gas fields have been developed and proved in Ordos Basin, Mizhi, Wushenqi,Daniudi, Shenmu and Sulige, in which accumulation reserves of tight gas reached 3.78 x l012 m3. At present, the field has now en- tered a stage of rapid growth of reserves production. The average annual increase of reserves is more than 5 000 ~ 10s m3 in the past five years, and the average annual increase of tight gas production is 30 ~ 108 m3. A tight gas production base was established, taking Sulige gas field as the representation. Key technologies of tight gas explora- tion and development were integrated innovated around full digital seismic, optimization of drilling, reservoir recon- struction, downhole choke, draining gas exploitation technology and digital management. The mode of development was changed to f |
