  • Publication number: 20240310861
    Abstract: A method, an apparatus and a system for automatically adjusting an opening degree of a fluid control valve, relating to the technical field of oil and gas exploration and development. The method includes: establishing a fluid control valve having an orifice structure in oil and gas production; using a numerical simulation method to obtain the influence law of minimum opening degree adjustment step on oil and gas production; obtaining relevant production test data of the oil and gas well, and calculating the total oil and gas production and the oil and gas production of each production layer based on the production test data of the oil and gas well; dividing the production layer segments into high, middle and low-production layers according to the production ratio of each production layer segment; respectively calculating the average productions of the high, middle and low-production layers.

  • Patent number: 12013226
    Abstract: The present disclosure provides a method for calibrating a rotation center based on a blade local leading-edge curve feature. The method acquires a blade local leading-edge curve feature before and after rotation, solves centroid coordinates according to maximum values in the blade local leading-edge curve features in the two times, and then solves a rotation center according to the centroid coordinates, thereby calibrating a coordinate of the rotation center. Compared with a point calibration method in the prior art, the present disclosure has a more accurate result by curve calibration and is more suitable for a real rotation center; and the method also has a more accurate blade measurement result when applied to measuring a blade cross-section curve feature.
