关键技术的突破促进塔里木气区的发现
|
摘要
塔里木气区包括塔北—库车气区和塔西南气区两大部份。塔北—库车气区已成为我国最大的天然气富集区之一 ,该气区北部存在着特大型气田 ,但地势陡峻 ,地质结构复杂 ,长期以来是勘探工作的禁区。经过近十年的系统攻关 ,关键技术获得重要进展 :一是山地地震勘探取得突破 ;二是综合地质研究取得新认识 ;三是复杂地质条件下的钻探取得成功。这些技术促使库车地区天然气勘探获得大进展 ,并发现了克拉 2号特大型气田 ,探明储量 2 5 0 6× 10 8m3,是“西气东输”的主力气田。目前 ,塔里木气区已探明天然气储量 46 88× 10 8m3 (16 5TCF) ,对“西气东输”项目的启动做出了重要贡献
The Tarim gas province consist of two major gas regions(Tabei kuqa and Taxinan).The Tabei region has becom one of the largest natural gas belts in China.In the north of this region,there exist exceptionally large gas fields.Due to the high relief of topography and complexity of geological structure in the region,traditional exploration methods could not be used.Through nearly ten years of tackling of key technical problems,significant progress was made,such as pioneering of seismic exploration in mountain areas,new interpretation of comprehensive geological results and successful drilling under complex geological conditions. All those technical innovations have greatly facilitated the development of natural gas in Kuqa area and a giant gas field,Kela No 2 (Kara Ⅱ)was discovered.The proven reserve of natural gas in this gas field is 250 6 billion cubic meters which makes it a major gas source of the “West to East Gas Transmitting Project.”The proven natural gas reserve of the Tarim Basin is 468 8 cubic meters (16 5 TCF).The discovery is a catalyst for the commencement of the project to transmit natural gas from the Tarim Basin to Eastern China.
