摘　　要：苏里格气田地质条件复杂、储层物性差、天然气丰度低、单井产量低,甚至不压裂就无自然产能,并且产量下降快,稳产期短,开采速度和采收率都比较低,经济效益较差,这类气藏国内外尚未形成一套完整成熟的开发技术。针对这些情况,根据气井生产动态特征,建立了苏里格气田单井分类标准,综合运用气藏工程方法分析了各类气井的动态特征和递减规律,通过压降法、产量递减法和累计产量法对气井动态可采储量进行了准确评价,并针对性地提出了井下节流保持稳产,合理配产以提高可采储量,后期间歇生产以动用外围低渗透储量的单井管理方法,以期为类似于苏里格气田的低渗透强非均质性气藏的高效合理开发提供理论基础和技术支持。Sulige gas field is characterized by complicated geological settings,poor physical property,low gas abundance,low individual well productivity,no natural deliverability without being fractured,rapid productivity decline,short period of stabilized production,low productivity and recovery ratio and low economic benefits.And there is no mature development technology available all over the world for the field like this one.According to this kind of situation,individual well classification criteria suitable for Sulige Gas Field is formed based on the characteristics of the gas well production history,production history and decline principle of different kind of gas well are analyzed synthetically by utilizing the technology of gas reservoir engineering,precise evaluation to the dynamic recoverable reserve is carried out with the method of pressure drop,production decline and cumulative production.And corresponding measures are proposed,such as flow restriction in the bottom hole to stabilize the production,reasonable allocation to improve the recoverable reserve and individual well management of batch production in the later stage to employ the reserve of the peripheral zone.And all the measures above would provide theory basis and technology supports to the efficient and reasonable development of low permeability and high heterogeneity gas reservoir similar to Sulige Gas Field.
