Establishment method, application and device of tight gas well drainage gas recovery measure chart

The invention relates to an establishment method, application and device for a drainage gas production measure chart of a tight gas well, and the establishment method couples the flow characteristics of a reservoir and a shaft, and proposes a drainage gas production measure suggestion chart of gas wells in different states on the basis of determining the critical point of liquid-carrying production of the gas well under the conditions of self-spraying and foam drainage. The method fills the blank that the method does not take the reservoir state into consideration to formulate measures at present, has a certain guiding effect on site measure decision, and is wide in application prospect. 本发明涉及一种致密气井排水采气措施图版的建立方法、应用及装置，其中，该建立方法耦合了储层和井筒的流动特征，在确定自喷和泡排条件下气井可携液生产的临界点的基础上，提出了不同状态气井的排液采气措施建议图版，填补了目前方法均没有考虑到储层状态来制定措施的空白，方法对于现场措施决策具有一定的指导作用，应用前景广阔。
