The embodiment of the application discloses a method and equipment for measuring oil well production based on energy spectrum signals, belonging to the technical field of oil well production measurement. Determine the first oil production rate of the oil well to be tested according to the logging curve; collect energy spectrum signals for the water-bearing crude oil exploited in multiple time periods to determine the water cut; The crude oil output corresponding to each time period; Among them, multiple time periods are part of the time when the oil well to be tested has been exploited; the remaining production time is determined according to the water content; according to the crude oil production and the remaining production time, each period in the remaining production time is determined Predict the production ratio corresponding to the time period; determine the second oil production of the oil well to be tested according to the crude oil production and the production ratio; when the error value between the first oil production and the second oil production is less than the preset error value , taking the second oil production rate as the final oil production rate.
Description
technical field [0001] The present application relates to the technical field of oil well production measurement, in particular to a method and equipment for oil well production measurement based on energy spectrum signals. Background technique [0002] Oil well production measurement is an important task in oilfield production management. Accurate and timely measurement of oil well production has important guiding significance for mastering reservoir conditions and formulating production plans. [0003] In the prior art, the output of the oil well is measured before the oil well is exploited to determine whether the oil well meets the requirement of exploitation. However, in the process of oil well exploitation, the output of crude oil is constantly decreasing, and the output of crude oil extracted by the mining personnel through the same extraction time is also constantly changing. And when the oil content in the oil well is low, the production will be stopped. However, ...
