Abstract
The utility model discloses a high-frequency vibration type oil well drill bit, and belongs to the field of oil drilling machinery. The high-frequency vibration type oil well drill bit mainly solves the problems of serious bit wear and high drilling cost during the conventional oil well drilling process. The high-frequency vibration type oil well drill bit structurally comprises a cable, a high-frequency energy converter, a vibration amplitude transformer, a protective guard, a spring shield, a guide rod, a spring, a drill bit and a guide sleeve, wherein the cable is connected to the high-frequency energy converter; the tail end of the high-frequency energy converter is connected onto the tail end of the vibration amplitude transformer; the protective guard covers the periphery of the high-frequency energy converter and the vibration amplitude transformer; the tail end of the vibration amplitude transformer is connected to the upper end of the drill bit; the guide rod is positioned at the upper part of the drill bit; the spring is mounted on the guide rod; the spring shield covers the periphery of the spring; the guide sleeve is mounted on the guide rod through a through hole at the upper end. A high-frequency vibration device is additionally arranged at the back of the drill bit during the using process, so that the drill bit is kept at a vibration state during the drilling process, the drilling environment of the drill bit is improved, the service life of the drill bit is prolonged, the manufacturing structure is simple, and the application range is wide.
Description
Technical field
The utility model relates to a kind of high frequency vibrating ejector half drill for oil well, belongs to oil drilling mechanical field.
Background technology
First oil drilling need to carry out drillng operation on the earth's surface on oil reservoir, needs to use drill for oil well in process, and it mainly contains pyriform milling miser, bottom three gear wheels, single-cone rotary drill bit, the sharp-eyed drill bit of neck, Rhizoma Sparganii shape drill bit etc.In drilling process, drill bit directly contacts with rock-soil layer, by revolving force, the geotechnical structure on earth's surface is carried out to fragmentation, so the common serious wear of drill for oil well, and in drilling process, cost is very high.
In existing disclosed document, as similar with conventional bit in this drill bit use procedure of CN302658319 < < diamond drill for oil well > >, owing to having inlayed diamond, improved application life, but cost is high.
Utility model content
The utility model is serious for bit wear in current oil well drilling process, and the problem that drilling cost is high has designed a kind of high frequency vibrating ejector half drill for oil well.
The technical scheme in the invention for solving the technical problem is:
This high frequency vibrating ejector half drill for oil well comprises cable, high-frequency transducer, vibration ultrasonic transformer, guard shield, spring shield, guide peg, spring, drill bit, fairlead; Cable connects high-frequency transducer, high-frequency transducer end connects on vibration ultrasonic transformer end, guard shield is wrapped in high-frequency transducer with around vibration ultrasonic transformer, vibration ultrasonic transformer end is connected to drill bit upper end, guide peg is positioned at drill bit top, spring fitting is on guide peg, and spring shield is wrapped in around spring, and fairlead is installed on guide peg morning by the through hole of upper end.
Described spring shield upper end is connected to guard shield bottom, and spring shield interior bone diameter equates with fairlead external diameter.
Described guide peg upper end is connected to guard shield bottom, and there is circular projection guide peg bottom, and there is the through hole of receiving drill bit at guide peg middle part.
Described spring top contacts with guard shield, and spring bottom contacts with fairlead end face.
There is shrinkage cavity structure described fairlead upper end, and there is the through hole of receiving drill bit fairlead inside.
The utility model has the following advantages:
1. the utility model is novel unique, in use procedure owing to having increased high-frequency vibration device at drill bit rear portion, make drill bit in drilling process in vibrational state, improved the drilling environment of drill bit, be conducive to extend the application life of drill bit.
2. making is simple in structure, and application is wide.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure figure.
In figure: 1 cable, 2 high-frequency transducers, 3 vibration ultrasonic transformers, 4 guard shields, 5 spring shields, 6 guide pegs, 7 springs, 8 drill bits, 9 fairleads.
The specific embodiment
As shown in Figure 1: a kind of high frequency vibrating ejector half drill for oil well, its structure comprises: cable, high-frequency transducer, vibration ultrasonic transformer, guard shield, spring shield, guide peg, spring, drill bit, fairlead; Cable connects high-frequency transducer, high-frequency transducer end connects on vibration ultrasonic transformer end, guard shield is wrapped in high-frequency transducer with around vibration ultrasonic transformer, vibration ultrasonic transformer end is connected to drill bit upper end, guide peg is positioned at drill bit top, spring fitting is on guide peg, and spring shield is wrapped in around spring, and fairlead is installed on guide peg morning by the through hole of upper end; Spring shield upper end is connected to guard shield bottom, and spring shield interior bone diameter equates with fairlead external diameter; Guide peg upper end is connected to guard shield bottom, and there is circular projection guide peg bottom, and there is the through hole of receiving drill bit at guide peg middle part; Spring top contacts with guard shield, and spring bottom contacts with fairlead end face; There is shrinkage cavity structure fairlead upper end, and there is the through hole of receiving drill bit fairlead inside.
During use, this high frequency vibrating ejector half drill for oil well is arranged on conventional probing bar, sends in prospect pit, start power supply and carry out oil well probing.
The above, be only the specific embodiment of the present utility model, and in the scope that those of ordinary skill in the art disclose at the utility model, the variation that can expect easily, within all should being encompassed in the protection domain of utility model.
