摘　　要：罗家寨气田飞仙关组气藏属于高含硫气藏 ,其有效储层厚度大、孔渗条件好、单井测试产量大 ,但是由于气藏高含硫化氢、中含二氧化碳的特征 ,使得其开采难度高 ,开发投资大 ,因此提高气藏开发效益、降低开发井投资的关键 ,就在于进一步提高气井单井产能、培育单井产能在 10 0× 10 4m3 以上的高产气井。文章利用圈闭评价、气藏描述、储量计算、现代试井等技术对气藏沉积相、储层特征及纵横向分布情况、储量情况和单井测试情况等方面进行了综合分析认为 ,罗家寨气田飞仙关组气藏储层发育、储量大 ,具备了高产井培育的地质条件。并进一步利用数值模拟技术对部署的开发井罗家 16H井的研究和论证后认为 ,通过水平井等工艺技术可以大幅提高单井产能 ,达到罗家寨气田飞仙关组气藏培育 10 0× 10 4m3 以上高产井的目的。The Feixianguan gas reservoir of Luojiazhai field is a high sulphur content gas reservoir with these characteristics as large effective pay thickness, good porosity and permeability, and great single-well testing production. Gas reservoir development is of great difficulty and needs a large investment, because of its high hydrogen sulfide content and medium CO2 content. On the basin of analyzing comprehensively the sedimentary facies and depositional features of the reservoir and its vertical and lateral distribution, and the gas reserves and single-well testing data of the reservoir, etc., by use of these techniques as trap evaluation reservoir description, reserve estimation and down-to-date well testing, etc., it is considered that this gas reservoir is of the geological conditions of drilling high productivity well, having fair reservoir beds and a large number of reserves. In light of studying the well Luojia 16H, a development well, by applying numerical simulation technique and through demonstration, it is thought that the aim of drilling high productivity wells with output of more than 100 × 104 m3 may be attained by adopting some techniques as drilling horizontal well. etc., to raise greatly the single-well deliverability.
