摘要：普光气田属高含H2S 和CO2特大型海相气田，具有气藏埋藏深、厚度大、非均质强、有边底水以及开发投资高和难度大的特点，国内没有成熟的开发技术和经验。为此，采用气藏工程理论方法、数值模拟和经济评价技术，对高含硫碳酸盐岩气藏开发层系划分、井型优选、合理井距、井网部署、合理产量、合理采气速度、单井技术经济界限、控制和减缓边底水推进、防止硫沉积等开发技术政策进行了优化研究，形成了高含硫碳酸盐岩气藏开发技术政策优化技术方法，并制定出适合普光气田的合理开发技术政策，为气田开发方案的编制及优化调整和气田高效开发奠定了基础。

Abstract:

Abstract: Puguang gas field is a superlarge marine carbonate gas field in China featuring in deep burial, large thickness, strong heterogeneity, high H2S and CO2 contents and edgeand bottomwater. Gas reservoir engineering theory and methodologies, numerical simulation and economic evaluation techniques are used to optimize the technical policies for its development, including layer division, welltype selection, reasonable well spacing,well pattern, reasonable productivity, reasonable gas production rate, technical and economic limits of single well, control and impediment of edgebottom water advancing, prevention of sulfur precipitation and so on. A set of technical methods are formulated for optimizing technical policies of carbonate sour gas reservoirs and are applied to Puguang gas field. The rational technical policies obtained provide a solid basis for development planning and adjustment and effective development of this gas field.
