Abstract
The utility model relates to the oil field applied technology field and belongs to a power type hollow flexible shaft particularly for oil-water well oil reservoir fixed point deep piercing horizontal drilling device. The utility model solves the problem that: a common power type solid flexible shaft has no central passage and can not transfer high pressure water flow. The utility model consists of an upper rolling joint 1, a metal hose 2, a flexible shaft body 3 and a lower rolling joint 4, wherein a central passage is arranged at the center of the metal hose 2. The utility model which is mainly applied to the oil-water well oil reservoir fixed point deep piercing horizontal drilling operation has the advantages of simple and novel structure; the utility model retains the characteristics of the common power type solid flexible shaft on one hand, and is provided with the central passage capable of transferring high pressure water flow on the other hand.
Description
Technical field: the present invention relates to the field use technical field, belong to a kind of hollow flexible axle of power-type of oil-water well oil layer positioning deep penetration horizontal drilling device special use.
Background technique: at present, the every field flexible axle that uses is solid construction both at home and abroad, does not have central passage, can not transmit high-pressure water flow.Oil-water well oil layer positioning deep penetration horizontal drilling device desired power type flexible axle is a hollow-core construction, need increase central passage in the central position of solid flexible axle, can transmit high-pressure water flow, satisfy the demand of oil-water well oil layer positioning deep penetration horizontal drilling device circulation chip removal and cooling drill bit.
Summary of the invention: the object of the invention provides a kind ofly offers central duct in the flexible axle central position, is used for transmitting the hollow flexible axle of power-type of high-pressure water flow.
The present invention is made up of top roll crimp head, metallic hose, flexible axle main body, lower roll crimp head, wherein the first end of top roll crimping is to have externally threaded spiral shell head, top roll crimp head spiral shell head is a tubulose with top, the first end of lower roll crimping also is to have externally threaded spiral shell head, lower roll crimp head spiral shell head also is a tubulose with top, the two ends of flexible axle main body are inserted into respectively in the pipe of top roll crimp head and lower roll crimp head and with tube wall crimping securely, and central duct is offered in the central position of metallic hose.
Metallic hose is the flexible flexible pipe of being made by the 1Cr18Ni9Ti stainless steel, and its internal diameter is Φ 4mm.
Compared with the prior art the present invention has the following advantages:
1), simple in structure, novelty, uniqueness;
2) on the basis of the solid flexible axle of common power type, having designed the axle center internal diameter is the hollow flexible axle of Φ 4mm, has promptly kept the characteristics of the solid flexible axle of common power type, has increased central duct again, can transmit high-pressure water flow.
Description of drawings: Fig. 1 is a structural representation of the present invention.
Embodiment: the invention will be further described below in conjunction with accompanying drawing: the present invention is by top roll crimp head 1, metallic hose 2, flexible axle main body 3, lower roll crimp head 4 is formed, wherein top roll crimp head 1 one ends are to have externally threaded spiral shell head, top roll crimp head 1 spiral shell head is a tubulose with top, lower roll crimp head 4 one ends also are to have externally threaded spiral shell head, lower roll crimp head 4 spiral shell heads also are tubuloses with top, the two ends of flexible axle main body 3 are inserted into respectively in the pipe of top roll crimp head 1 and lower roll crimp head 4 and with tube wall crimping securely, and central duct is offered in the central position of metallic hose 2.
During on-the-spot the use, the present invention realizes its function by oil-water well oil layer positioning deep penetration horizontal drilling device.In carrying out the positioning deep penetration horizontal drilling process, the power system of utilizing oil-water well oil layer positioning deep penetration horizontal drilling device provides power for the rotation and the feeding of the hollow flexible axle of power-type, make power-type hollow flexible axle carry drill bit and carry out horizontal drilling, and can regulate the rotational speed and the feed speed of the hollow flexible axle of power-type, gear pump by oil-water well oil layer positioning deep penetration horizontal drilling device provides high-pressure water flow, after the central duct of the metallic hose 2 by the hollow flexible axle of power-type, penetrate from the hydrophthalmia of chisel edge, rock chip in the time of promptly can discharging boring, the purpose of the boring that is up to the standard.
