摘要
大庆外围气田属低渗透、低产砂岩气藏。为了不断发展完善适应这类气田开发的采气工艺技术 ,经过十多年的开发 ,研究成功了排水采气、压裂、堵水等一整套的气藏开采工艺技术 ,这些技术对气藏的高效、合理地开采提供了保证。通过介绍大庆油田外围低渗透气田的各项采气工艺技术现状、应用特点和对采气工艺面临的问题的分析 ,提出了下步研究方向 ,为松辽盆地北部深层气、海拉尔盆地CO2 气及黑龙江东部煤层气的开发提供技术储备。
Daqing peripheral gas field is a sandstone gas reservoir with low permeability and low production. In order to continuously develop and complete the gas production techniques suitable for recovering this kind of gas reservoirs,for more than ten years' development, a set of gas reservoir production techniques has been studied successfully, such as gas production by water draining, fracturing and water plugging. These techniques make the gas reservoir to be produced effectively and reasonably. This paper introduces the actuality and characteristic of the gas production techniques and analyzes the problems of the techniques to present the next researching direction. It provides the technical reserve for recovering the deep gas of northern Songliao Basin, CO 2 of Hailaer Basin and the coalbed gas of eastern Heilongjiang.
