低渗气藏单井合理井距确定方法

合理高效的开发气藏是人们所共同追求的。在进行气藏开发方案编制时,井网的布置则成为关键之一,因此,有必要对气藏单井的合理井距进行研究,尤其对于低渗气藏,在渗透条件较差的情况下,要考虑气体流动的约束条件。文章从气井供气半径、启动压力梯度、经济极限储量等多因素考虑出发,综合确定低渗气藏单井合理井距,为气藏合理布井提供理论指导。

Rational and efficient development of the gas reservoir is the pursuit of the common people. Gas reservoir in the preparation of development programmers, the pattern of the layout has become one of the key, therefore, it is necessary for the reasonable gas reservoir wells from single well to study, especially for low permeability gas reservoirs in the infiltration of the disadvantaged circumstances, To consider the gas flow eonstraints. Articles from the refueling radius of gas wells, starting pressure gradient, the economic limit reserves, and other factors to consider departure, comprehensive set of low permeability gas wells from single well rational, reasonable for the gas reservoir cloth wells provide theoretical guidance.
