Problems solved by technology
Most of the methods use the peak area ratio of adjacent peaks (fingerprints) as the fingerprint parameter. Although this can eliminate the influence of sampling errors on the analysis results, a large number of crude oil samples are required for the proportioning experiment.
However, the water content of oil wells in most oilfields in China is relatively high, and in order to avoid the influence of other chemical substances, crude oil samples are not suitable for chemical dehydration, so it is difficult to obtain a large number of crude oil samples, which limits the use of chromatographic fingerprinting in determining the single-layer combined production well.

The invention discloses a single-layer yield calculation method and device for a two-layer commingled production well and a readable storage medium. The single-layer yield calculation method for the two-layer commingled production well comprises the following steps of obtaining the total yield of the commingled production produced by the commingled production well; obtaining a first sample, a second sample and a third sample; respectively carrying out gas chromatography detection on the dehydrated first sample, second sample and third sample; manufacturing a standard fingerprint pattern plate;determining the absolute concentration of each fingerprint compound on a third gas chromatogram, and projecting the absolute concentration to a standard fingerprint pattern plate; determining the crude oil production from the first horizon and from the second horizon. The method has the beneficial effects that the single-layer yield contribution ratio of the two-layer commingled production well is calculated according to the absolute concentration of the fingerprint compound, the defect that a large number of crude oil samples are required to be subjected to proportioning experiments due to the fact that the peak area ratio of adjacent peaks is selected as a fingerprint parameter traditionally is avoided, and therefore the requirement for the crude oil sample amount is lowered.
Description
technical field [0001] The invention relates to the technical field of petroleum development, in particular to a single-layer production calculation method, equipment and readable storage medium of a two-layer combined production well. Background technique [0002] In order to optimize production, many production and development wells are produced in the mixed production of two oil layers. Find out the contribution ratio of each single oil layer to the production of the two-layer combined production wells, and dynamically monitor the change of oil production with the production time, monitor the production performance of oil wells, It is of great significance for oilfields to formulate and adjust development plans and optimize oilfield management to carry out stratified management of oil reservoirs and identify whether there is channeling of oil wells or edge water intrusion. [0003] The single-layer production contribution rate of two-layer combined production wells can be...
