陕北浅层低渗透油田伴生气基本上是直接排放到大气中 ,既浪费资源 ,又污染环境 ,以陕北川口油田为例 ,运用容积法计算得出陕北川口油田北区 2 7.84km2范围内 ,伴生气地质储量为 4.94× 1 0 8m3。据南 47井、南 70井和白 2 2井原油地层水及 PVT分析化验资料 ,运用物质平衡法确定其伴生气采收率分别为 71 .5 6 % ,75 .0 2 %和 74.94%。在此基础上得出 ,该区伴生气可采储量为 3 .6 5× 1 0 8m3 ,具有巨大的商业价值。 The associated gas in Shaanbei shallow low-permeability oilfield is basically discharged directly to the atmosphere, which is not only a waste of resources but also pollute the environment. Taking Kawaguchi oil field in northern Shaanxi as an example, the volumetric method is used to calculate the range of 2 7.84km2 in the north of Kawaguchi oilfield Within the associated gas geological reserves of 4.94 × 1 0 8m3. According to the data of formation water and PVT analysis of wells in South 47, South 70 and Ba 2 2 wells, the associated gas recovery was determined by material balance method to be 71.56%, 75.02% and 74.94% respectively. On this basis, it is concluded that recoverable gas reserves in this area are 3.56 × 10 8 m 3, which has great commercial value.
