摘　　要：喇嘛甸油田先后经历了基础井网、一次加密、二次加密、一类油层聚驱、二类油层上返开发等开发阶段，形成了以水驱井网为基础，多套井网共存的开发模式。随着油田进入特高含水开发期，目前现有的笼统测压系统出现较大的不适应性。在应用笼统测压系统分析目前油田多套井网压力系统变化的基础上，并应用RFT、MDT等单井分层测压资料，通过分析不同类型油层地层压力变化情况，结合原始地层压力特点，按照不同井网、不同开发阶段、不同开发方式分析油层压力系统特征，找到了影响地层压力变化的因素，指导了油田综合调整。Lamadian oilfield has gone through stages of basic well pattern, first infilling, second infilling, polymer flood of type Ⅰ reservoir, and upward development of type Ⅱ reservoir. A development model based on water flooding pattern with multiple sets of pattern combined has taken shape in the progress. As the entrance of the oilfield to super-high water-cut stage, the existing general pressure measuring system presents inadaptability. On the basis of analysis on pressure system change of multiple patterns applying general pressure measuring system, utilizing single well pressure measuring data such as RFT and MDT, through analyzing the pressure changes of different formations, considering the original formation pressure characteristics and different patterns, development stages and development methods, formation pressure system characteristics is analyzed, the factors that influence formation pressure is found, and comprehensive adjustment of oilfield is guided.
