Method for optimizing oil well acquisition indicator diagram storing mode

Abstract

The invention discloses a method for optimizing an oil well acquisition indicator diagram storing mode. The method comprises the following steps of performing overlay analysis of indicator diagrams in one day by utilizing superposition technology to obtain superposed diagrams and memorizing the superposed diagrams in a memorizer; obtaining a variation diagram of liquid production quantity with time according to daily fluid output amounts corresponding to the indicator diagrams in one day and memorizing the variation diagram in the memorizer; and selecting and memorizing a representative superposed diagram capable of reflecting real work condition of one day and calculating average daily fluid output amount. Multiple indicator diagrams of an oil well in one day are replaced by three diagrams, a memorizing space occupied by the indicator diagrams is decreased, query time is decreased, the central processing unit (CPU) occupancy rate of a server is reduced, the operation speed of the server is improved, historical production situations of the oil well can be really reflected, and historical query in the future is facilitated.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a method for optimizing the storage mode of oil well acquisition indicator diagrams. Background technique [0002] In order to improve the operating efficiency of the first-line production organization in the oilfield, optimize the labor organization method, and improve the management mode of the oil and gas field, Changqing Oilfield Oil and Gas Technology Research Institute independently developed an oil and water well working condition analysis system. Through the use of oil and water well working condition analysis system, real-time production calculation of oil wells, real-time intelligent diagnosis and analysis of working conditions, three-level fault early warning and other functions are realized. [0003] The oil and water well working condition analysis system surveys a set of dynamometer data for each managed oil well at a frequency of 10 minutes. A total of 144 dynamomet...
