摘　　要：南海东部A油田是典型的底水油藏水平井增产改造开发区,在开发过程中,不同油层与油井含水上升规律存在明显差异,制约了该油藏的高效开采。基于A油田原始数据建立综合地质模型,结合实际生产动态,归纳出四种含水上升模式并找出对应的影响因素,利用正交试验进行多因素分析并找出主控因素。此典型区块丰富的实际数据,有望为底水油藏高效开发提供参考。A oilfield in the eastern South China Sea is a typical horizontal well stimulation development zone of bottom water reservoir.In the development process,there are obvious differences in the water cut rising law of different oil layers and oil wells,which restricts the efficient exploitation of the reservoir.Based on the original data of A oilfield,a comprehensive geological model is established.Combined with the actual production performance,four water cut rising modes are summarized and the corresponding influencing factors are found out.The orthogonal test is used to carry out multi-factor analysis and find out the main controlling factors.The rich actual data of typical blocks is expected to provide reference for the efficient development of bottom water reservoirs.
