高含硫气藏在我国分布较少，积累的开发经验也有限，而在法国、加拿大等国家的高含硫气藏开发中，既有成功的经验，也有失败的教训。罗家寨飞仙关鲕滩气藏是川渝境内首次发现的高孔高渗高含硫气藏，由于硫化氢具较强的腐蚀性和毒剧性而给气田的开发带来较大难度，为了高效合理地开发气田，对气田的布井方式研究意义重大。章在对罗家寨飞仙关鲕滩气藏的地质特征和流体特征进行分析研究的基础上，对气藏采用了布丛式井、直井两种类型的布井方式，丛式井布井方式又分为4口井组式和3口井组式，直井布井方式采用匀均布井，利用数值模拟技术对气藏不同布井方式、生产井数及开采规模进行了模拟研究，研究结果表明该气藏采用不同布井方式，在相同井数、相同开采规模的条件下，不同的布井方式，开发技术指标相同。通过对气藏布井方式影响因素的分析，认为丛式井布井是气藏最佳的布井方式，且气藏合理的生产井数为10口。

Well Spacing Study for the Development of Feixianguan Oolitic Shoal Gas Reservoir in Luojiazhai

Gas reservoirs with high sulfur content are found sparsely in China.So,the experience to develop them is not enough.There are some successful experiences,also some lessons for developing gas reservoirs with high sulfur content in the countries such as France,Canada,etc.Feixianguan oolitic shoal gas reservoir is the first found gas reservoir with high porosity,high permeability,and high sulfur content in Sichuan Basin.It is difficulty to develop the gas reservoir because hydrogen sulfide has strong corrosion and toxicity.To develop the gas field efficiently and properly, studying well spacing of the field has great signification.Based on the study of geologic and fluid characteristics of Feixianguan oolitic shoal gas reservoir,well spacing was simulated with both cluster wells and straight wells.The cluster wells include 4 branch holes type and 3 branch holes type.The straight wells are placed uniformly.Using numerical simulation,the different well spacing types,producing well number,and recovery scale were simulated.The results show with the same well number,and the same recovery scale,the development technical indexes are the same when using different well spacing type.Analyzing the influence of different well spacing on the gas reservoir development,it is suggested that cluster wells are the optimum choice for well spacing type,and the proper number of producing wells is 10.
