鄂尔多斯盆地天然气勘探开发战略研讨

EXPANDING STRATEGY OF NATURAL GAS EXPLORATION AND DEVELOPMENT IN E’ERDUOSI BASIN

鄂尔多斯盆地近几年天然气勘探开发取得了快速发展,仅长庆探区探明天然气地质储量累计就达1.1954×1012m3,并建成年产天然气75×108m3 的生产能力,成功地向北京、上海、西安、银川、呼和浩特等重点城市供气。该盆地已成为我国重要的天然气生产基地之一。最新评价成果显示,盆地天然气资源量达10.7×1012m3,随着国家对天然气能源日益增长的需求,长庆油田分公司加快天然气勘探开发的条件正在成熟。通过强化科技攻关,加大勘探力度,不断开拓天然气勘探新领域,保持储量的良性接替是天然气产业发展的重要前提;同时,进一步推广使用开发新工艺、新技术,实施低成本战略。预计到2010 年,鄂尔多斯盆地天然气探明地质储量将达到1.5×1012m3,形成180×108m3 的天然气年生产能力。

The natural gas exploration and development in E'erduosi Basin have achieved a rapid expansion in recent years, the proved gas reserves in place being up to 1.1954 × 1012 m3 in total only at Changqing region, a gas productivity of 7.5 × 109 m 3/a having been built up and the natural gas having been supplied to many key cities as Beijing, Shanghai, Xi' an, Yinchuan and Huhehaote, etc. E'erduosi Basin has become one of the important gas production bases in China. The newest evaluation results show that the gas resources in the basin is up to 10.7 × 1012 m3; and the conditions have been trending toward being ripe for speeding up natural gas exploration and development by the Changqing Oil Field Branch, PCL, along with an increasing demand for natural gas in China. Through investigation it was considered that it is very important for expanding the natural gas industry to strengthen the research of key scientific and technological projects, to open up the new fields for gas exploration unceasingly and to maintain g good replacement of gas reserves;and the low-cost strategy should be carried out by further popularizing and utilizing new development methods and techniques. It was predicted that the proved gas reserves in place in E'erduosi Basin will be up to 1.5 × 1012 m3 in 2010 and :a yearly productive capacity of 18 × 109 m3 will be formed.
