Abstract

The invention discloses a quantitative well selection method and device based on oil well measures, and belongs to the technical field of oil field development. The method includes: determining the influencing factors of various oil well measures; for each type of oil well measure, determining the influence interval of the oil well measure according to the degree of influence of the influencing factors of the oil well measure on the effect of the oil well measure; calculating the corresponding influence interval of each type of oil well measure The impact degree value of the measure effect; generate the influence factor quantification table corresponding to each type of oil well measure. The quantitative table of influencing factors of oil well measures and the performance index value of the single well to be tested determine the implementation coefficient of the single well to be tested; when the implementation coefficient of the single well to be tested meets the preset conditions, it is judged that the single well to be tested is the implementation well. Since the quantitative method is used for well selection, the precision of well selection is higher, and the cumulative oil increment can be increased.

Description

technical field [0001] The invention relates to the field of oil field development, in particular to a quantitative well selection method and device based on oil well measures. Background technique [0002] With the deepening of oilfield development, the resources of high-quality and efficient measures are gradually scarce. The current development trend of oil well measures is from within the layer system to outside the layer system; from the first type of layer to the second type of layer such as water-flooded layer and oil-water layer; from a single measure to a combination of measures, and the difficulty of well selection for backup measures is increasing. In order to achieve stable production and increase production, the quality of measures must be improved. In the traditional way, when selecting wells, relying on the geological analysis results and experience judgment results of geologists, the measure wells or measure layers are qualitatively selected. However, this ...
