Description

Simple clamp spring type underground fishing device

Technical Field

The utility model relates to the technical field of drilling underground accident treatment, in particular to a simple clamp spring type underground fishing device.

Background

During the production process of oil and gas wells, geothermal wells and water wells, underground falling objects and underground tools are often stuck due to various reasons. Various underground falling objects influence the normal production of oil and gas wells, geothermal wells and water wells to a great extent, and can cause production stop when serious. Therefore, the corresponding fishing tools are selected according to different types of underground falling objects, the underground falling objects are fished out, and normal production is recovered. In the well repairing operation, the fishing operation accounts for more than two thirds, and the underground falling objects are various in types and different in shapes, and mainly comprise pipe falling objects, rod falling objects, rope falling objects, underground instrument and tool falling objects, damaged rubber, slips, grinding and milling metal chips and the like; the fishing tools are designed and manufactured aiming at the characteristics of different falling objects, mainly comprise a fishing barrel, a fishing spear, a male cone, a female cone, a strong magnetic fishing device, a tiger mouth, an inner hook, an outer hook, a grab, a fishing cup, a wire brush and the like, and the fishing tools can not be used for fishing underground tubular falling objects and rod falling objects.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present invention, it should also be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

The utility model is described in further detail below with reference to the accompanying figures 1-2:

referring to fig. 1, a simple and easy jump ring type is fishing device in pit includes:

a cylinder body 2 with an opening and a clamp spring device 3 arranged in the cylinder body 2;

wherein, jump ring ware 3 includes a plurality of flexure strips 31, and a plurality of flexure strips 31 along the same high lateral wall annular setting in barrel 2.

Referring to fig. 2, the gap between adjacent elastic pieces 31 is flared. The elastic piece 31 has a shape with two high ends and a low middle. One end of each elastic sheet 31 is fixedly connected with the inner wall of the barrel 2 and winds the inner wall of the barrel 2 for one circle, and the other ends of the elastic sheets 31 are not contacted with each other and encircle to form a round hole. And the elastic piece 31 is a metal elastic piece 31. Set up like this, when salvaging, with the device down to above the fish top, carry out the reverse circulation earlier and wash, break up rock debris, the deposit etc. in the pit with accumulational, slowly rotate simultaneously and transfer barrel 2, in introducing barrel 2 with the fish that falls, continue rotatory below and salvage for fish one end that falls gets into jump ring ware 3 can't fall under the stopping of jump ring ware 3, lifts, carries the fish that falls in the pit to ground, reaches the salvage purpose.

Further, the number of the elastic pieces 31 is designed to be different according to the weight, shape and size of the fish falling down the well, for example, the fish falling in the shape of a small tube can be provided with 6-8 groups of elastic pieces 31 with lower rigidity. The round and square fish filets with larger importance are provided with 3-5 groups of elastic pieces 31 with larger rigidity.

Still further, barrel 2 one end is equipped with connects 1, connects 1 and be cylindric and with the coaxial setting of barrel 2, connects 1 diameter to be greater than the diameter of barrel 2. The arrangement is convenient for a user to operate. The joint 1 and the cylinder 2 are integrally formed.
