摘要：

我国中西部中、新生界前陆盆地,具有优越的天然气地质条件,天然气资源量约占全国天然气资源量的四分之一。近年来,在这些盆地中天然气勘探取得了一系列重大突破,发现了克拉2、依南2、白马庙、呼图壁、南八仙等多个大、中型气田,充分证实中西部前陆盆地是当前我国陆上天然气最有利的勘探领域,其中库车、川西、准噶尔南缘、柴达木北缘是今后勘探的重点。为使中西部前陆盆地天然气勘探取得更大的突破,必须加强山地地震勘探、复杂储集层的识别与预测,以及钻井完井工艺等技术的攻关。

Abstract:

Meso-Cenozoic foreland basins in Central-west China have favourable geological conditions and gas resource potential,and their natural gas reserves are one fourth of the total amount of China's gas reserves.In recent years,a series of important breakthroughs in gas exploration have been made,a number of big and medium gas fields including Kela-2,Yinan-2,Baimamiao,Hutubi and Nanbaxian gas fields have been discovered.This thus further proved that the foreland basins in Central-west China are the most favourable target areas for gas exploration,and Kuqa,west Sichuan,the south marginal area of Junggar Basin and the north marginal area of Qaidam Basin should be the focal point targets.To make even great breakthrough of gas exploration in the study area,seismic exploration in mountains,the recognition and prediction of complex reservoirs,well drilling and well completion technologies should be strenghened.

Key words: China, foreland basin, natural gas, exploration realm, technical countermeasure
