摘要: 大牛地气田为低孔低渗透气田,按照不同的方法计算了其极限井距和技术合理井距,并以经济评价方法为基础确定了气藏的合理井距。认为只要技术合理井距不低于其经济极限井距都是可行的。建议:在相对高渗透层采用密井获得高产,在低渗透层采用稀井保证整个气藏开发的经济效益。最后结合数值模拟方法确定高渗透层(Ⅰ类区)井网采用1 000 m井距,低渗透层(Ⅱ类区)井网采用1 500 m井距。

关键词: 低渗透, 井网密度, 非均匀井距

Abstract:

Da NiuDi field is a lower permeability gas field. This paper calculates ultimate interwell distance and technical rational spacing between wells by different ways;on the base of the economic assessment method ascertain the rational spacing between wells in the field. Based on the study, we think that t it is reasonable that the technical rational spacing between wells is more than
the economical ultimate interwell distance. Then it has been put forward to deploy the close-spaced well in the relative high permeable bed to get high product produce, and to deploys the light-spaced well in the lower permeable bed to get good economic effect. Finally combining the study and the numerical simulation to ascertain the interwell distance in the high permeable bed is 1000m,the one is 1500m in the lower permeable bed.

Key words: low permeability, well spacing density, heterogeneous pattern well spacing
