Abstract
The utility model relates to a tool for oil well repair work, particularly to a primer lead mold. The primer lead mold comprises an upper joint, a protective cover and metallic lead, wherein a female thread is formed on the upper joint; a rod body is arranged at the lower end of the upper joint; a male thread is formed at the bottom end of the rod body; the protective cover is arranged on the outer side of the rod body; the metallic lead is connected between the protective cover and the rod body; and circulating water holes are formed in the upper joint and in the center of the rod body. The primer lead mold can be connected with a trace column so as to prevent the loss of the trace column or the fish top of a casing pipe, and can be used for spying the situations of the fish top, a well cylinder, falling objects and the like. The tool overcomes the defects that the traditional lead mold can only be connected with the bottom of a drilling tool but cannot be connected with the trace column and the trace column and the fish top of the casing pipe are easy to lose.
Description
Technical field:
The utility model relates to a kind of petroleum well workover power tool, particularly a kind of introduction lead stamp.
Background technology:
At present, in the petroleum well workover operation, the cover method is bought or get by illegal means in commonly used getting to be spike tubing string method and once to overlap milling.Spike tubing string method: get the cover before in well, be lowered to suitable dimension drilling tool as the spike tubing string.Mill at cutting, cover, in the processes such as salvaging, back-off, milling, printing, the spike tubing string is applied in well head and the production string all the time, loses in bore hole to prevent top of fish.Conventional lead stamp can only be connected the bottom of drilling tool, can not be connected with the spike tubing string, and spike tubing string and sleeve pipe top of fish are prone to lose.
The utility model content:
The technical problem that the utility model will solve provides a kind of introduction lead stamp, and this lead stamp has been realized being connected with the spike tubing string, prevents that spike tubing string or sleeve pipe top of fish from losing, and can be used in situation such as visiting top of fish, pit shaft, junk.Overcome the bottom that existing lead stamp can only be connected drilling tool, can not be connected, the deficiency that spike tubing string and sleeve pipe top of fish are prone to lose with the spike tubing string.
The technical scheme that the utility model is taked is: a kind of introduction lead stamp comprises top connection, protective cover and metallic lead; Top connection is provided with box thread, and the top connection lower end is provided with the body of rod, and body of rod bottom is provided with male thread, and the body of rod outside is provided with protective cover, is connected with metallic lead between the protective cover and the body of rod, and top connection and body of rod center have the circulation hydrophthalmia.
The beneficial effect of the utility model is: the utility model is owing to adopted the top connection lower end to be provided with the body of rod; Body of rod bottom is provided with the mode of male thread; Thereby have with the spike tubing string and be connected; Prevent the function that spike tubing string or sleeve pipe top of fish are lost, and can be used in situation such as visiting top of fish, pit shaft, junk.
Description of drawings:
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation.
Accompanying drawing is the structural representation of the utility model.
The specific embodiment:
Shown in accompanying drawing, a kind of introduction lead stamp comprises top connection 1, protective cover 2 and metallic lead 3; Top connection 1 is provided with box thread, and top connection 1 lower end is provided with the body of rod, and body of rod bottom is provided with male thread 5, and the body of rod outside is provided with protective cover 2, is connected with metallic lead 3 between the protective cover 2 and the body of rod, and top connection 1 has circulation hydrophthalmia 4 with body of rod center.
It is understandable that; More than about the specific descriptions of the utility model; Only be used to the utility model is described and be not to be subject to the described technical scheme of the utility model embodiment; Those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model, to reach identical technique effect; As long as satisfy the use needs, all within the protection domain of the utility model.
