摘　　要：靖边北外围下古生界气藏位于靖边气田北部，与苏里格气田毗邻。主要含气层位为马家沟组马五1＋2与马五4，紧密围绕长庆油田公司建设“西部大庆”战略目标，通过对靖边气田周边下古完钻井的地质及测试资料分析．开展气田周边下古气藏的地质特征研究及储层评价，明确气田周边下古气藏储量状况，圈定下步建产有利区，估算地质储量，评价建产潜力，为气田周边开发目标优选提供地质依据。2011年在优选的有利区内通过实施开发井24口均获得成功．靖边北外围扩边建产取得新突破。Closely around the Changqing Oilfield Company＇s strategic objective of building another ＂Daqiug Oil- field＂ in western China,through analysis of geological and testing data of wells completed in Lower Paleozoic surrounding Jingbian gasfield,we carry out in this article the geological characteristics study and reservoir evalu- ation of Lower Paleozoie gas reservoirs surrounding the gasfield. The reserves conditions of Lower Paleozoic gas reservoirs sun＇ounding the gasfield are crystallized. Next favorable areas for productivity establishment are delin- eated. The geological reserves are estimated. The productivity establishment potential is evaluated. Thus it pro- vides a geological basis for optimization of development goals of the gasfield surroundings. In the preferred bene- ficial regions,the implementation of 24 development wells was successfully completed in 2011. The productivity establishment in peripheral expansion makes new breakthroughs in North Jingbian Gasfield.
