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。
Midwestern and western Central China, the Cenozoic foreland basin, with superior geological conditions of natural gas, natural gas resources account for about a quarter of the country’s natural gas resources. In recent years, a series of major breakthroughs have been made in natural gas exploration in these basins. A number of large and medium-sized gas fields such as Kela 2, Inan 2, Baimamiao, Hutubi, and Nanbaixian were discovered, fully confirming that the central and western foreland basins are At present, the most favorable exploration field for onshore natural gas in China is Kuqa, western Sichuan, southern Junggar and the northern Qaidam. In order to make more breakthroughs in natural gas exploration in the foreland basin in the central and western regions, we must step up the exploration of technologies for mountain seismic exploration, identification and prediction of complex reservoirs, and drilling and completion technologies.
