Set up toper direction spring among the general sucker rod fishing tool, in toper direction spring channeled into the sucker rod in the salvage sleeve, through behind the block tongue, the block tongue spring loosened the block tongue to sucker rod collar completely to the lower extreme that makes the block tongue block sucker rod collar is salvaged out with the sucker rod. A general sucker rod fishing tool simple structure, convenient operation salvages efficiently, and the expense is low.
Description
Technical field
The utility model belongs to petroleum drilling technology field, is specifically related to a kind of universal sucker rod fishing tool.
Background technology
In the recovery process of oil, sucker rod up and down reciprocatingly runs in well, be subject to alternate stress, sucker rod, due to factors such as manufacturing deficiency, fatigue, corrosion, produces fracture, threads off thus fall in well, need the salvaging carrying out sucker rod, existing sucker-rod fishing tool is of a great variety, due to the situation more complicated in well, sometimes also needs customization fishing tool to carry out sucker rod salvaging, thus causing salvage expenses high, salvaging efficiency is low.
Utility model content
The purpose of this utility model there are provided a kind of universal sucker rod fishing tool, to solve in prior art when salvaging sucker rod costly, inefficient problem.
The technical scheme that the utility model adopts is, a kind of universal sucker rod fishing tool, comprise fishing sleeve, be provided with cannelure a in fishing sleeve, cannelure a is near one end of fishing sleeve, and the other end of fishing sleeve is connected with taper guide spring, fishing sleeve is evenly provided with several inclined holes, be connected with spring plug wire, block tongue spring and block tongue in each inclined hole in turn, block tongue part is positioned at fishing sleeve, and block tongue is near taper guide spring.
Feature of the present utility model is also,
The internal thread coordinated with oil tube external thread is provided with in cannelure a.
Be provided with cannelure b in fishing sleeve, cannelure b is near the other end of fishing sleeve, and the miner diameter end of taper guide spring is positioned at cannelure b and welds with cannelure b.
Spring plug wire and inclined hole affixed.
Inclined hole evenly arranges 3.
The beneficial effects of the utility model are: arrange taper guide spring in a kind of universal sucker rod fishing tool, sucker rod imports in fishing sleeve by taper guide spring, rod collar is completely by after block tongue, block tongue spring unclamps block tongue, thus make block tongue block the lower end of rod collar, sucker rod is salvaged out.A kind of universal sucker rod fishing tool structure is simple, easy to operate, and salvaging efficiency is high, and expense is low.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of universal sucker rod fishing tool of the utility model.
In figure, 1. fishing sleeve, 2. spring plug wire, 3. block tongue spring, 4. block tongue, 5. taper guide spring, 6. cannelure a, 7. inclined hole, 8. cannelure b.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
The utility model provides a kind of universal sucker rod fishing tool, as shown in Figure 1, comprise fishing sleeve 1, be provided with cannelure a6 in fishing sleeve 1, cannelure a6 is near one end of fishing sleeve 1, and the other end of fishing sleeve 1 is connected with taper guide spring 5, fishing sleeve 1 is evenly provided with several inclined holes 7, be connected with spring plug wire 2, block tongue spring 3 and block tongue 4 in each inclined hole 7 in turn, block tongue 4 part is positioned at fishing sleeve 1, and block tongue 4 is near taper guide spring 5;
The internal thread coordinated with oil tube external thread is provided with in cannelure a6;
Be provided with cannelure b8 in fishing sleeve 1, cannelure b8 is near the other end of fishing sleeve 1, and the miner diameter end of taper guide spring 5 is positioned at cannelure b8 and welds with cannelure b8;
Spring plug wire 2 is affixed with inclined hole 7;
Inclined hole 7 evenly arranges 3.
The using method of a kind of universal sucker rod fishing tool of the utility model is: work as pumping rod disengaging, during fracture, oil pipe is moved on oil well, internal thread in cannelure a6 is connected with oil tube external thread, the utility model is made to stretch in accident well, when the utility model touches dropout or fractured sucker rod position, rotate oil pipe, now sucker rod imports in fishing sleeve 1 by taper guide spring 5, sucker rod enters block tongue 4 place, block tongue 4 compresses block tongue spring 3, rod collar is completely by after block tongue 4, external diameter due to rod collar is greater than the external diameter of sucker rod, now block tongue spring 3 unclamps block tongue 4, thus make block tongue 4 block the lower end of rod collar, sucker rod is salvaged out.
In a kind of universal sucker rod fishing tool, taper guide spring 5 is set, sucker rod imports in fishing sleeve 1 by taper guide spring 5, and rod collar is completely by after block tongue 4, and block tongue spring 3 unclamps block tongue 4, thus make block tongue 4 block the lower end of rod collar, sucker rod is salvaged out.A kind of universal sucker rod fishing tool structure is simple, easy to operate, and salvaging efficiency is high, and expense is low.
