Embodiment Construction
[0031] Embodiments of the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only examples, rather than limiting the protection scope of the present invention.
[0032] According to an embodiment of the present invention, a well selection method for gas injection oil wells is provided, which is used to quickly select oil wells with gas injection potential in oil reservoir production areas, so as to increase oil and gas production recovery. In this embodiment, the gas injected into the oil well is nitrogen, and may also be other gases, such as a mixture of nitrogen and carbon dioxide. The following takes the well selection of gas injection wells in the ultra-deep fracture-vuggy reservoir of Tahe Oilfield as an example to introduce the well selection method in detail. Such a...
