Description
technical field [0001] The invention relates to the field of fish throwers, in particular to a fish thrower for highly inclined water injection wells and a use method. Background technique [0002] Highly inclined water injection wells are widely used in oilfield production. Because of their excessive inclination, the lower side of the labor injector is easily affected by its own gravity. The wall of the injection well is prone to friction and collision, which affects the working effect of the labor injector. Contents of the invention [0003] The present invention aims at the above-mentioned deficiencies existing in the prior art, and provides an easy-to-adjust fishing device for high-inclination water injection wells and a usage method. [0004] The purpose of the present invention is to realize through the following technical solutions: [0005] A fishing device for high-inclination water injection wells, including a fixed sleeve, a fastening sleeve, a protective sleev...
