大牛地气田位于陕西省榆林市和内蒙古鄂尔多斯市交界地区。经过多年的勘探,根据3次资源评价,该区块上古生界三级储量为5256.80×108m3。截至2007年底,共获探明储量3293.04×108m3,达到了大型气田规模。一、管理创新背景大牛地气田属河道沉积砂岩气藏,共有7套气层,气田具有储量规模大,发育多套气层,储层非均质性强,低压、低渗、低丰度、低产特点。由于气田地处高寒地区,冬季气温极低,排水采气和水合物生成造成的堵塞是气田生产过程
Daniudi gas field is located in Yulin, Shaanxi Province and Inner Mongolia Erdos border area. After years of exploration, according to the evaluation of 3 resources, the Upper Triassic reserve of the block is 5256.80 × 108m3. As of the end of 2007, a total proven reserves of 3293.04 × 108m3, reaching a large-scale gas field scale. I. Background of Management Innovation Daniudi gas field is a channel sedimentary sandstone gas reservoir with a total of 7 sets of gas reservoirs. The gas field has large reserves, multiple sets of gas reservoirs, strong reservoir heterogeneity, low pressure, low permeability and low abundance , Low yield characteristics. Due to the gas field is located in the alpine region, the winter temperature is very low, the formation of drainage gas and hydrate blockage is the gas field production process
