摘　　要：阳信地区沙一段气藏是胜利油区天然气产能建设的一个重要接替阵地,为了评价气井产能,了解储层渗透性以及确定合理的开发技术政策,对阳信地区三口获工业气流井进行了试气。根据常规气藏工程方法及数值模拟研究,阳信地区合理的开发技术政策是:采用一套层系开发;单井初期产能为0.61×104m3/d;宜采用在含气范围内均匀布井的方式,气藏井距800m;采气速度4.8%。The gas reservoir in Yangxin district is the reserved position of gas production capacity construction in Shengli oilfield. In order to evaluate production capacity, comprehension permeability and establishment reasonable development technique policy, three industrial value wells have been tested. Through research of gas reservoir engineering and numeric simulation, the reasonable development technique policy is: a suit of development system, 0. 61×104 m3/d early well production capacity, uniformed well pattern, 800m well spacing, 4. 8% recovery rate. Owing to low permeability of gas reservoir in Yangxin district, protection during drilling and operation, reservoir transformation for well stimulation and pressurization development are keys of high development level.
