Embodiment Construction
[0017] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. The following preferred embodiments are only used to illustrate and explain the present invention, but not to limit the technical solution of the present invention.
[0018] refer to figure 1 As shown, the present invention proposes a gas-in-oil prediction method for combined prediction residual correction, comprising the following steps:
[0019] (1) The gas is separated by the oil-gas separation device, and the gas composition and ratio are analyzed by using the online chromatographic analysis of dissolved gas and the gas sensor, and the time series of dissolved gas is established, and the chromatographic data of the mass concentration of dissolved gas in oil are measured by a 220kV transformer in an electric power bureau As an example, a total of 7 sets of data (dissolved gas time series) were obtained, see Table...
