Embodiment Construction
[0084] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.
[0085] Comprehensively analyze the existing methods for determining the intermittent production system of low-permeability reservoirs. The current method of establishing the technology is not accurate enough. The inflow dynamic equation generally adopts the general vogel equation or some simplified productivity formulas, which cannot accurately describe the seepage law of low-permeability reservoirs; the intermittent process The real-time dynamic change of bottomhole flow pressure and pump efficiency cannot be realized; the upper or lower bound of the gap range is delineated through qua...
