Example Embodiment
[0024] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings and examples thereby using techniques for application techniques to solve technical problems, and achieving technology effects can fully understand and implement it. It should be noted that the various embodiments in the present invention and the respective features of the present invention may be combined with each other, and the form of the invention is within the scope of the invention.
[0025] Most of the production capacity prediction of the oil and gas field is the first to return to the existing production data, and then use the equation obtained by the regression method to perform capacity prediction. Traditional analysis of production data is usually based on material balancing conditions and three ideal assumptions, namely a vertical well, formation boundary closure, and flow reach the boundary flow stage. In the field of production data analysis...
