陕甘宁盆地中部大气田是我国目前最大的气田,并步入储量>1000×108m3的世界大气田行列。高速、高效探明该气田的基本经验是稀并广探。实现稀井广探,必须解放思想,转变观念,对地下规律要有一个正确的认识;抓住古地貌大潜台和弧形云坪相带,制定与勘探目标相适应的勘探方针和部署方案;通过扎实过硬的基础工作,建立齐全准确的第一性资料;选用先进、适用的工艺配套技术,形成五位一体的综合勘探。从成藏基本地质条件分析,中部气田必须向大气区方向发展,前景十分乐观。
The gas field in the central part of the Shaan-Gan-Ning Basin is the largest gas field in China and has entered the ranks of the world’s major gas fields with reserves of> 1000 × 108 m3. The basic experience of high-speed and high-efficiency exploration of the gas field is lean and broad. In order to realize the exploration of dilute wells, we must emancipate our minds, change our concepts, and have a correct understanding of the underground laws. We should seize the paleoporphyic submarine platform and the arched cloud plateau to formulate exploration policies and deployment plans that are compatible with the exploration targets ; Through solid foundation work, the establishment of complete and accurate first-rate information; selection of advanced and applicable technology supporting technology to form a five-in-one comprehensive exploration. From the analysis of the basic geological conditions for gas accumulation, the central gas field must develop toward the atmosphere area with a very optimistic outlook.
