摘      要：QT油田是一个复杂小断块油田,区域内发育各级断层接近200条,将油区分割成74个含油断块,构造断裂复杂,断层多,断块小,油藏类型多样。2018年以来,没有补充的新增储量和未动用储量,产量也逐年下降,稳产的难度加大。通过对QT油田复杂断块油藏进行研究分类,找出不同油藏的地质条件特点对开发效果的影响,从而找到相对应的开发方式,实现提高油田效益和油藏采收率。QT oilfield is a complex and small fault block oilfield, with nearly 200 faults of various levels developed in the area, which divides the oil area into 74 oil-bearing fault blocks, with complex structural faults, many faults, small fault blocks, and diverse reservoir types. Since 2018, there have been no new reserves and unutilized reserves, and the difficulty of stabilizing production has increased, and the output has declined year by year. Through the study and classification of complex fault block reservoirs in QT oilfield, the influence of geological conditions of different reservoirs on development results is found, so as to find the corresponding development methods to improve oilfield benefits and reservoir recovery efficiency.
