摘　　要：针对渤海L油田碳酸盐岩储层类型复杂、开发规律认识不清等难题,剖析碳酸盐岩储层试井响应特征,将渤海L油田试井曲线特征分为5类,并找出了试井曲线特征、生产动态与碳酸盐岩储层特征的对应关系;利用动静态资料,评价了各井不同的储层特征,将渤海L油田碳酸盐岩储层划分为孔隙-裂缝型和裂缝-孔隙型两种类型;建立了L油田碳酸盐岩储层特征识别模板,实现了储层复杂渗流特征的精细刻画。该技术对区域的勘探开发一体化实践具有一定的指导意义,也为类似复杂碳酸盐岩油气藏储层研究提供了技术借鉴。The carbonate reservoirs types are complex in Bohai L oilfield,it is difficult to understand the development performance,thus well test characteristics were analyzed,there were five types of of pressures transient characteristics and correspondence to different carbonate reservoirs types and production performance.Combined static and dynamic data,reservoir characteristics were estimated and carbonate reservoirs types were divided into two types:pore-fracture and fracture-pore.The curves reflect the reservoir physical property and reservoir types in Bohai L Oilfield,getting a better understanding of reservoir characteristic and realizing the fine description of dynamic flow,which has a certain guiding significance for exploitation and development of this field,and provides a reference for similar complex carbonate reservoirs.
