靖边气田具有上、下古生界两套气层，上古气层发育，但储层物性差，按照目前技术和政策开发经济效益较差，利用完善的下古开发井网，结合上古气井测井解释和储层分类标准，建立上古气井优选经验公式，优选气井进行产能预测，选取预测产能较高、井筒状况较好、下古生产情况较差的气井进行上古储层查层补孔作业，降低改造成本，提高气井产能，实现靖边气田的高效和可持续开发。
靖邊氣田具有上、下古生界兩套氣層，上古氣層髮育，但儲層物性差，按照目前技術和政策開髮經濟效益較差，利用完善的下古開髮井網，結閤上古氣井測井解釋和儲層分類標準，建立上古氣井優選經驗公式，優選氣井進行產能預測，選取預測產能較高、井筒狀況較好、下古生產情況較差的氣井進行上古儲層查層補孔作業，降低改造成本，提高氣井產能，實現靖邊氣田的高效和可持續開髮。

Jingbian gas filed have two gas bearing reservoir,Neopaleozoic and Lower Palaeo- zoic Group,the Neopaleozoic gas bearing reservoir upgrowthes,but the reservoir physical property is poor, according to the technique and policy in nowadays, development economic results is relatively low. Utilizing consummate Lower Palaeozoic Group well pattern,uniting Neopaleozoic gas well logging interpretation and reservoir clascification criteria, Neopaleozoic gas well optimize empirical formula was builded,which was used to optimize gas well to fore- cast fluids rate, select highly fluids rate, better wellbore condition and poorly production of Lower Palaeozoic Group to check layer and patch perforation in Neopaleozoic reservoir, cut reformation cost, enhance gas well productivity, realize high efficiency and sustainable devel- opment of Jingbian gas filed.
