靖边气田加密井部署条件研究

Study of Infill Drilling Deployment Conditions in Jingbian Gasfield

靖边气田下古储层非均质性较强，不同气井的泄气半径差异较大，然而气井的泄气半径是井区加密布井的最重要参数。传统方法在计算泄气半径时，有的不考虑储层的边界和非均质性，有的却要求得到气井的产能试井资料；这些方法都不能大量的用来确定气井的泄气半径。从由动储量确定气井泄气半径，方法实用、简洁，并据此确定加密井部署条件。

Lower Paleozoic reservoirs if Jingbian gasfield have strong heterogeneity. The various gas wells have different drainage radius. The gas well drainage radius is the most important parameter for infill well drilling arrangement. When calculating the gas well drainage radius, some of the traditional methods do not consider the margins and reservoir heterogeneity. Some have asked for the data from gas well deliverability testing. These methods could not be vastly used to determine the gas well deflating radius. The gas well drainage radius is determined in the light of dynamic reserves. The methods are practical and concise, and thus confirm conditions for the deployment of infill wells.
