Analysis of Influencing Factors on the Law of Water Cut Rising in Horizontal Wells in Bottom Water Reservoir—Take the East South China Sea A Oilfield as an example
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.
