Problems solved by technology
Although the method of numerical simulation has also been applied to the evaluation of the production status of oil and gas wells, this method has the defects of "large parameter uncertainty" and "large error of multiphase flow", which leads to the low fitting degree of the model, which affects the evaluation objectivity of results

The invention provides a method and device for determining a measure potential well. The method comprises the steps: obtaining a feature model of a reference well according to a first production parameter and a second production parameter of the reference well; obtaining a wellhead oil pressure difference value of the to-be-evaluated well according to the feature model and the first production parameter and the second production parameter of the to-be-evaluated well; if the wellhead oil pressure difference value is smaller than a preset value, the to-be-evaluated well is a measure potential well; wherein the first production parameters comprise a production time parameter, a unit period gas production rate parameter, a unit period liquid production rate parameter and a wellhead temperatureparameter, and the second production parameters comprise a wellhead oil pressure parameter. According to the method, potential wells can be objectively screened and determined from a large number ofto-be-evaluated wells to take measures.
Description
technical field [0001] The invention relates to a determination method and a determination device for a measure potential well, and belongs to the technical field of self-flowing well transformation. Background technique [0002] In order to consider the cost of the measures and ensure that the production capacity can be effectively increased after the measures are taken, the potential of oil and gas wells needs to be evaluated and screened before the measures are tapped, and then the potential taps of the oil and gas wells with potential for improvement are carried out according to the potential evaluation results. [0003] In the prior art, the evaluation method for the measure potential of oil and gas wells is as follows: if the production status of a certain well is good for a long time, it is determined that the well does not have the measure potential; measure potential. That is, to evaluate the potential of measures according to the production status of oil and gas w...
