Abstract
A horizontal well telescopic printing lead stamp for complete overhaul of petroleum and natural gas extraction horizontal wells comprises an upper joint, sealing rings, a connecting cylinder belt protective sleeve, a piston, a spring, pins, a lead stamp assembly, a steel ball base and a lead stamp, wherein the upper joint is connected with the connecting cylinder belt protective sleeve through screw threads, the sealing rings are both arranged on the joints of the upper joint with the connecting cylinder belt protective sleeve and the piston with the connecting cylinder belt protective sleeve, the connection between the piston and the connecting cylinder belt protective sleeve is in a slide sealing type, the spring is arranged on the outer diameter of the piston, and the connecting cylinder belt protective sleeve is fixed with the lead stamp assembly through the pins, the steel ball base is arranged on the bottom of the lead stamp assembly, the lead stamp is arranged on bottom of the lead stamp assembly, and is cast with the lead stamp assembly. The lead stamp solves the problems that prints can be damaged by the vertical friction of well wall in a conventional lead stamp in the prior art, thereby being unable to judge the underground fish trouble and the damage condition of a bushing. The horizontal well telescopic printing lead stamp can be widely applied in the complete overhaul of petroleum and natural gas extraction horizontal wells.
Description
Technical field:
The utility model relates to the telescopic printing lead stamp of horizontal well that a kind of oil, the overhaul of natural gas extraction horizontal well are used.
Background technology:
The oil field usually need be printed in high angle hole section and net horizontal section, so that implement the damaged condition of fish or sleeve pipe in horizontal well overhaul process.Owing to there is not corresponding confirmation instrument, can not finish this work at present, the influence that conventional lead stamp is rubbed up and down along journey by the borehole wall damages the trace of printing, and can't judge the truth of down-hole fish or sleeve pipe.The current effective instrument of neither one of going back can be got trace clearly under this circumstances.We develop a kind of new printing lead stamp in production practices, solved the problem that existing conventional lead stamp exists.
The utility model content:
The purpose of this utility model provides the telescopic printing lead stamp of a kind of horizontal well, and this lead stamp has solved the conventional lead stamp that exists in the prior art and has been subjected to borehole wall frictional influence trace up and down, can't judge the problem of down-hole fish or sleeve pipe damaged condition.
The technical scheme that its technical problem that solves the utility model adopts is: the telescopic printing lead stamp of horizontal well; by top connection; sealing ring; connecting cylinder band protective sleeve; piston; spring; pin; the lead stamp assembly; steel ball seat; lead stamp is formed: top connection is threaded with connecting cylinder band protective sleeve; at top connection and connecting cylinder band protective sleeve; piston and connecting cylinder protective sleeve junction are equipped with sealing ring; piston is that slipper seal is connected with connecting cylinder band protective sleeve; spring is located on the piston external diameter; connecting cylinder band protective sleeve and lead stamp assembly pass through dowel fixes; steel ball seat is located at the bottom of lead stamp assembly, and lead stamp is located at the bottom pouring combination of lead stamp assembly.During work: top connection is connected the back G.I.H with drill string, throws steel ball to predetermined above well-flushing down; The drill string inner chamber is suppressed, and cuts off pin; In the compression of drilling tool chamber pressure effect lower spring, lead stamp is pushed out connecting cylinder band protective sleeve by the lead stamp assembly; Continue to add hydraulic pressure, descent of piston is printed; On carry drill string, lead stamp is recovered under spring action in the connecting cylinder band protective sleeve, trips out ground.
The beneficial effects of the utility model are: the utility model is relatively simple for structure, and is easy to use; It is the method that has adopted protective sleeve, can stretch out and shrink, and the lead stamp that quality is softer protects, the damage in having avoided removing; This printing lead stamp has solved horizontal well and has printed difficult problem, can analyze, judge the shape of down-hole fish or sleeve pipe more accurately by trace clearly, for selecting fishing tool that foundation is provided, improved well workover efficient, save cost of production, shortened the production cycle.
Description of drawings:
Accompanying drawing is the utility model overall structure schematic diagram.
Among the figure 1, top connection, 2, sealing ring, 3, connecting cylinder band protective sleeve, 4, piston, 5, spring, 6, pin, 7, the lead stamp assembly, 8, steel ball seat, 9, lead stamp.
The specific embodiment
In the accompanying drawings; the telescopic printing lead stamp of horizontal well; by top connection 1; sealing ring 2; connecting cylinder band protective sleeve 3; piston 4; spring 5; pin 6; lead stamp assembly 7; steel ball seat 8; lead stamp 9 is formed: top connection 1 is threaded with connecting cylinder band protective sleeve 3; at top connection 1 and connecting cylinder band protective sleeve 3; piston 4 is equipped with sealing ring with connecting cylinder protective sleeve 3 junctions; piston 3 is connected for slipper seal with connecting cylinder band protective sleeve 3; spring 5 is located on piston 4 external diameters; connecting cylinder band protective sleeve 3 is fixing by pin 6 with lead stamp assembly 7; steel ball seat 8 is located at the bottom of lead stamp assembly 7, and lead stamp 9 is located at the bottom pouring combination of lead stamp assembly 7.
