摘　　要：海上平台近年来发生的多起重大事故都与伴生气藏的泄漏有关,伴生气藏对海上油田开发的影响应引起重视。以PX油田、CX油气田、旅大4-2油田的开发实践为例,探讨伴生气藏所引发的问题及其应对方法。利用储层地质知识库技术和三维地震资料“亮点”技术识别被气云覆盖的储层,利用油气平衡开采提高石油采收率,同时配套补孔采气、钻调整井、优化注水、LPG回收等手段,实现海上伴生气的经济高效开发。Multiple major accidents on offshore platforms in recent years have been related to the leakage of associated gas reservoirs,and the impact of associated gas reservoirs on offshore oilfield development should be taken seriously.Taking the development practices of PX Oilfield,CX Oil and Gas Field,and LD 4-2 Oilfield as examples,the problems caused by associated gas reservoirs and their response methods are explored in this paper.The reservoir geological knowledge base technology and 3D seismic data"bright spots"technology are adopted to identify reservoirs covered by gas clouds,and oil and gas balance extraction is utilized to improve oil recovery efficiency.At the same time,it is equipped with methods such as additional perforation,drilling and adjusting wells,optimizing water injection,and recovering LPG to achieve economic and efficient development of offshore associated gas.
