Abstract

The invention discloses an oil well indicator diagram data duplicate checking method which comprises the following steps: acquiring indicator diagram data of all oil wells in a well area within one day, and defining effective indicator diagram data; grouping and screening the indicator diagram data of all oil wells in one day, and counting the quantity of grouped effective indicator diagram data to obtain a repeated indicator diagram data sample and a repeated indicator diagram data test sample set; screening to-be-checked duplicate indicator diagram data of all oil wells according to the duplicate indicator diagram data inspection sample set to obtain all duplicate indicator diagram data and a duplicate indicator diagram data result set; according to the repeated indicator diagram data in the repeated indicator diagram data result set and the well names thereof, obtaining a repeated indicator diagram statistical result set based on the single well names; obtaining a well name association relation table of the repeated indicator diagram data according to the repeated indicator diagram data in the repeated indicator diagram data result set and different well repetition conditions thereof; and according to the well name association relation table of the repeated indicator diagram data, obtaining all different well repeated records of each piece of repeated indicator diagram data.

Description

technical field [0001] The application relates to the technical field of data analysis and processing of oil production work diagrams with rods in oil fields, and in particular to a method for checking duplicates of work diagram data of oil wells. Background technique [0002] Pumping wells are a common method in oilfield development at present, and the management level of pumping wells is related to the overall economic benefits of the oilfield. The oil well polished rod indicator diagram is the main means to understand the working conditions of the downhole pipes, rods and pumps of the rod pumping unit, and this data is also the basis for measuring the production based on the dynamometer data. [0003] At present, it often takes 10 minutes to collect 1 work map data according to the needs. There are no less than 200 points in each work map data, and each point is stored in 4 bytes. In this way, each well can generate 144 work map data under normal conditions every day. To...
