Abstract
The utility model belongs to a fishing tool for underground fallen objects in seismic exploration work of oil industry system. The top end of a fishing spear body (1) and a female buckle (3) matched with a drill rod are connected with a drilling tool. A spear body is made into triangular pyramid-shaped, the spear body is provided with more than two small openings, and more than two outwards extended notch-shaped elastic pieces (2) are respectively arranged on the spear body corresponding to the two small openings. The utility model has the advantage that a drilling toll of the underground fallen objects can be rapidly and successfully taken out to cause exploration work to be normally proceed.
Description
One, technical field:
Fishing spear belongs to the fishing tool of petroleum industry system trouble of lost tool in hole in seismic survey work.
Two, technical background:
Current, in seismic survey work,, multiple factor happens occasionally owing to causing the fall phenomenon of the well or the well that fractures of drilling tool button, and in the salvage process, owing to there is not suitable special implement, often salvage relatively difficulty, and influence the process of investigation and prospecting.
Three, summary of the invention:
The purpose of this utility model provides a kind of fishing spear, is convenient to the trouble of lost tool in hole drilling tool is salvaged taking-up; The top of this fishing spear is the box that matches with drilling rod, is connected with drilling tool during use, and the lance body is made the prismatic taper, so that can insert the inside of well drilling tool smoothly.The lance body is shaped on two above osculums, and corresponding making respectively more than two slightly to the card port shape shell fragment of abduction so that increase lance body diameter, can closely be connected with lower drilling tool when making fishing spear work smoothly.
The beneficial effects of the utility model are that this Special Fishing Tools is arranged, and just can take out trouble of lost tool in hole fast smoothly, and investigation and prospecting is normally gone on.
Four, description of drawings:
As figure is structural representation of the present utility model.
1-fishing spear body 2-card port shape shell fragment 3-box among the figure
Five, embodiment:
As seen from the figure, the box 3 that the top of fishing spear body 1 and drilling rod match is connected with drilling tool, and the lance body is made the prismatic taper, and the lance body is shaped on two above osculums, the corresponding card port shape shell fragment of making respectively more than two to abduction 2.During use, with on this fishing spear in drilling tool lower going-into-well together, in the well drilling tool apical position test that falls, strive for being inserted in the well drilling tool.Fishing spear is more directly perceived, in case drilling tool fails to inject drilling rod inside, make marks this moment on the drilling rod of ground, uses more moderate rig power roof pressure several times, and the position of observing mark is tight to determine whether to connect, and carries the drilling tool well drilling tool that will fall on then and salvages out.
Claims (1)
1, a kind of fishing spear is characterized in that the top of fishing spear body (1) is connected with drilling tool with the box (3) that drilling rod matches, and the lance body is made the prismatic taper, and the lance body is shaped on two above osculums, the corresponding card port shape shell fragment of making respectively more than two to abduction (2).
