摘　　要：M油田为超深水碳酸盐岩油田,水深超过2000m,地质背景特殊,油藏条件复杂,储层连通性、储层物性、单井长期产能等关键问题亟待落实;超深水油田开发进度要求高,能否在早期对该油田进行有效评价直接决定开发成败。借助已钻评价井建立小型试采单元,围绕主要地下风险进行多种形式的动态资料录取,结合测试目的完成录取资料解释,落实单井长期产能、储层连通状况等关键认识,为油田开发方案的编制与优化提供有力依据;基于压力监测数据完成模型历史拟合,提升了预测指标的可靠性。M oilfield is an ultra-deep water carbonate oilfield with a water depth of more than 2000m.It has a special geological background and complex reservoir conditions.Key issues such as reservoir connectivity,reservoir physical property and long-term productivity of a single well need to be addressed.The development schedule of ultra-deep water oilfield is demanding.Whether to evaluate the oilfield effectively in the early stage directly determines the success or failure of its development.A small test production unit was established with the help of the drilled evaluation well,and various forms of dynamic data were recruited around the main underground risks.The interpretation of the data was completed in combination with the test purpose,and key understandings such as long-term productivity of a single well and reservoir connectivity status were implemented to provide a strong basis for the preparation and optimization of oilfield development plans.The historical fitting of the model was completed based on the pressure monitoring data,which improved the reliability of the prediction index.
