近几年在鄂尔多斯盆地中部已发现多个储量规模上百亿立方米的天然气气田。富县勘探区位于该盆地的南部 ,该区奥陶系马家沟组为蒸发潮坪相沉积 ,具备形成天然气气藏的物质基础 ;本区上古生界处于生烃中心 ,气源充足 ;本区位于北部古潜台的延伸方向是有利的天然气勘探目标区。本文通过综合分析对富县勘探区古生界天然气勘探提出部署意见。
In recent years, several natural gas fields with reserves of tens of billions cubic meters have been discovered in the central Ordos Basin. The Fuxian prospecting area is located in the southern part of the basin. The Ordovician Majiagou Formation in this area is characterized by evaporization tidal flat, which has the material basis for the formation of natural gas reservoirs. The Upper Paleozoic in this area is at a hydrocarbon generation center with sufficient gas source. The extension of the area located in the northern ancient subtropical platform is a favorable gas exploration target area. In this paper, through comprehensive analysis of the exploration of the Paxian Gas Exploration Proposal proposed deployment.
