摘　　要：高含硫气田的开发安全条件要求高,技术难度大,开发成本高。储量和产量是决定高含硫气田开发经济效益的重要影响因素。单井日产量下限、单井控制地质储量下限是衡量高含硫气田达到经济高效开发的定量指标。建立了单井日产量下限、单井控制地质储量下限的数学模型。以某气井为例,计算并分析了天然气价格、气井投资、开采成本、产量变化模式等对单井日产量下限、单井控制地质储量下限的影响:①天然气价格与单井日产量下限、单井控制地质储量下限呈指数负相关函数关系;②气井投资、开采成本与单井日产量下限、单井控制地质储量下限呈直线正相关函数关系;③产量变化模式对单井日产量下限、单井控制地质储量下限影响最小。建议根据计算出的单井日产量下限、单井控制地质储量下限等参数来编制高含硫气田开发方案,以实现方案的总体经济效益达到最优。The development of high-sulfur gas field needs severe safe conditions ,which results to difficulty on technology and high cost.Economic benefit of developing the high-sulfur gas field depends on reserves and oil production mainly.Lower limit of daily oil production and controlled geologic reserves of single well are the quantitative targets of high-efficiency development in the high-sulfur gas fields.Mathematic models of these two targets were established.The influence of natural gas price ,gas well investment,exploitation cost and variation mode of oil production on the target was calculated analyzed in a certain gas well.The natural gas price is the function of exponential negative correlation of the two lower limits.The gas well investment and exploitation cost are the function of linear positive correlation of the two lower limits.The variation mode of oil production has few influences on the two lower limits.It is suggested that development plan should be programmed according to the calculated two lower limits so as to gain overall economic benefit.
