Abstract
The utility model discloses a fishing spear for the petroleum industry, which is adapted for the workover treatment operation of various oil wells, water wells and gas wells. The utility model is composed of an upper joint, a guide shoe tube, etc., wherein, the upper end of a spear rod in the guide shoe tube is connected to the upper joint by a coupler, and the lower end is connected with a die tap. The utility model has the advantages of simple structure, easy manufacture, high fishing efficiency and large achievement ratio, has both functions of repair and fishing, and completes the fish top repair and fishing at the same time. The utility model simplifies the normal fishing technology and lowers cost for oil production. Besides, the utility model has the function of cleaning the fish top when fish piles in varias.
Description
The utility model relates to the workover rig of petroleum industry, and particularly a kind of Fishing spear is applicable to the workover operation construction of various Oil, Water, Gas wells.
At present, at the oil well workover scene, because oil-water well underground working complexity, working procedure is various, has reasons such as operations against rules in addition, cause many oil pipes to fall accident that trouble of lost tool in hole such as well and top of fish be out of shape.Handling the common existing special tool that adopts of these trouble of lost tool in holes has: drag for use outside the curved fish dipper one, drag for use in the guide shoe die nipple one.Drag for a curved fish dipper processed complex of use outward, the manufacturing cost height; In drag for that to carry load on the guide shoe die nipple of use little, easy pull-off, processing cost height again when tubing string is met card.
The purpose of this utility model is a kind of workover tool that possesses reparation salvaging dual-use function of design, overcomes on above-mentioned interior vatman's tool and proposes little, the easy pull-off of load, and outer vatman's tool is made complexity, the shortcoming that cost is high.Make it simple in structure, easy to operate, cost is low, and collection is repaiied fish, salvaging and one, simplifies the treatment process of trouble of lost tool in hole accident, reduces cost for oil production.
Technical solution of the present utility model is: by top connection, drag for lance and guide shoe tube etc. and assembly Fishing spear, the lance bar upper end of dragging in the guide shoe tube links together by box cupling and top connection, lower end connection die nipple.
After using the utility model, realized repairing fish and salvaged incorporate operation procedure, simple to operate, efficiency of construction improves greatly.Because it is big to carry load on this instrument, the fishing success ratio height has been simplified the operation technique that conventional trouble of lost tool in hole is handled, and has shortened the operation duration, has reduced cost for oil production.
Accompanying drawing is a structural representation of the present utility model.
Below in conjunction with embodiment the utility model is done further detailed description: referring to accompanying drawing, the utility model is made up of top connection 1 and guide shoe tube 2 etc., the internal thread on top connection 1 top connects the drill string lower end, lance bar 4 upper ends of dragging in the guide shoe tube 2 link together by box cupling 3 and top connection 1, and the lower end connects die nipple 6.Guide shoe tube 2 covers from the outside and drags for lance bar 4 and die nipple 6, and dragging for lance bar 4 middle parts has 1 to several up big and down small inclined-planes, and design has the dovetail feather key on its inclined-plane, and tooth-sliding block 5 is installed on the dovetail feather key, and the external diameter that drags for lance bar 4 middle and lower parts is identical with the external diameter of die nipple 6.The one side that dovetail groove is arranged on the tooth-sliding block 5 is the inclined-plane, and its gradient conforms to the inclined-plane that drags for lance bar 4 middle parts, and another side is a dentalation.The utility model is connected to the drill string lower end when using, and down to TOF, rotation is also slowly transferred drill string, top of fish is introduced into guide shoe tube 2, die nipple 6 enters the fish chamber under the setting upright of guide shoe tube 2, under top drill string pressure and revolving force effect, and die nipple 6 and drag for lance bar 4 and get into fish fish chamber.On when carrying drill string tooth-sliding block 5 glide and be stuck on the fish inwall, on carry drill string fish pulled out outside the well, finish fishing process.It is one that the utility model is salvaged die nipple and drag for lance salvaging optimum organization, makes it possess the dual-use function of repairing with salvaging, and heaping fish has under the situation of foreign material such as cable, possesses the function of clearing up top of fish.
