Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method and equipment for fishing strings of soccer quarts from the bore of a well. In particular, the present invention provides a string of sucker rods in which the upper end of the cut portion is provided with a cut fiberglass string with a fiberglass string that is difficult to assemble into a bundle or group. The present invention relates to a method for removing a cut part of a well from a well bore, and a fishing gear.

Metal pumps have been used for many years in strings where wells drive downhole pumps to pump fluid from holes. Many times these sucker rod strings break due to overload, fatigue, corrosion, or physical damage. The portion of the metal sucker rod string left in the wellbore has a sucker rod end placed above the original rod diameter, equal to or shorter than the original rod diameter, and therefore over the sucker rod end and in a conventional manner. The well-known fishing gear presents little impediment to its progress.

U.S. Patent Nos. 2874937, 287 jj938, and 4195691 and 4195691
No. 956.740, previously abandoned, cited in U.S. Patent Application No. 576,731.
Fiberglass hooker quads, such as those disclosed in Canadian Patent No. 1,072,191, have been used in sucker rod strings. However, when the fiberglass sucker rod breaks, the resin strands shatter, causing multiple separated fiberglass strands of the fiberglass body of the sucker rod to spread laterally at the point of separation. Common overshot fishing gear has an inwardly tapered bottom surface to guide the common metal p-rad end inwardly;
The overshot can therefore be advanced downwardly around the rod, and it is necessary to engage the next lower sarakar rod connection member to remove the broken portion of the sucker rod string from the drilled bore.

When these well-known fishing tackles are used to fish broken fiberglass sucker rods, the large number of broken fiberglass struts tend to confuse, block and clog the overshot bore, thereby causing the fiberglass rod's failure. It also prevents a normal overshot that moves downwards to 5. It does not have a conventional sucker rod and therefore does not allow the fishing tackle to be passed downwardly around the cut leak in the fiberglass sucker rod.

It is therefore an object of the present invention to provide a new method and apparatus for fishing cut fiberglass sucker rods from a wellbore.

It is another object of the present invention to collect a large number of separated fiberglass strands of cut fiberglass sucker rods and to remove a portion of the remaining sucker quart string so that the sucker rod string can be raised from the well. An object of the present invention is to provide a gripping method and device.

The present invention provides for cutting fiberglass sucker rod strings from well bores where the broken rods have multiple fiberglass strands that are difficult to bundle or group and difficult to fish in separate strings. This invention relates to a method and device for fishing with a sucker rod. A generally tubular fishing tackle is provided having a collateral opening extending through the lowermost end. Such IIl apertures are provided in a longitudinally disposed first surface that is tapered at 5 to guide the fiberglass strands inwardly as the fishing tackle rotates, and in the upper and lower ends of the first surface. has a spiral second surface intersecting with each other. Each surface forms an acute angle with the outer cylindrical surface of the fishing tackle.

Above the side opening, the fishing tackle has a device for gripping a four-string soccer string. As the fishing tackle is lowered down around the cut end of the sucker rod, the fishing tackle rotates and bundles the numerous loose fiberglass strands into the fishing tackle by acting at an acute angle to the surface of the collateral opening. , so that the bundled fiber bundles do not confuse or clog the bore of the fishing gear. The fishing tackle is then pulled down further so that the device inside the fishing tackle can grip the sucker rod string;
The sucker rod string can then be attached to the fishing tackle and raised from the well bore.

Other objects and advantages of the present invention will become apparent from the following detailed description with reference to the drawings.

Although the invention is described in connection with preferred embodiments and methods, it should be understood that the invention is not limited to such embodiments and methods. On the contrary, it is evident that the invention includes all other alternatives, modifications and equivalents without departing from the spirit and scope of the invention as defined by the claims. be.
