Abstract
An all-aluminum light alloy drilling pipe comprises a drilling pipe body, a female joint and a male joint. The upper end and the lower end of the drilling pipe body are in thread pair threaded connection with the female joint and the male joint respectively, and the upper end of the female joint and the lower end of the male joint are in thread pair threaded connection. The all-aluminum light alloy drilling pipe is characterized in that one side of the tooth-shaped half angle of a thread pair formed by an inner thread at the upper end of the female joint and an outer thread at the lower end of the male joint is 10 degrees, and the other side of the tooth-shaped half angle is -3 degrees. The all-aluminum light alloy drilling pipe is further provided with rubber sealing rings at the two ends of the drilling pipe body and on the male joint. By means of the improvement, on one hand, sealing performance of the thread pair is improved, and on the other hand, the anti-pulling capacity of the drilling pipe is effectively improved and occurrence of drilling accidents is reduced. The novel drilling pipe is developed through optimization and improvement, the requirement of deep geology prospecting is met, and meanwhile certain reference value is provided for industrial standard formulating.
Description
Technical field
The utility model relates to a kind of probing utensil, specifically a kind of full aluminium light-alloy drilling rod.
Background technology
Full aluminium light-alloy drilling rod is applied in geological drilling field, is mainly used in fields water injection and pumping test, also for corrosive environment, drills; Meanwhile, full aluminium light-alloy drilling rod also can support the use with the ultraportable rig in area difficult to get access.Its effect is: for mud provides flow channel; For detritus instrument provides the pressure of the drill, transmitting torque; For extracting rock core, more bit change and accident are salvaged working material are provided; Measure definite hole depth; Understand situation and strata condition etc. in hole.Compare with drill steel, full aluminium light-alloy drilling rod can effectively prevent H
2s, CO
2corrosion, and full aluminium light-alloy drilling rod and nickel cobalt (alloy) have similarly without magnetic characteristic, and this is very favourable to magnetic logging.Simultaneously, for height above sea level, mountain shape is dangerously steep, with a varied topography, natural conditions are severe, geographical position is remote, ungetable special area, geological drilling construction operational difficulty, even some survey area cannot be executed brill, at these application aluminium drill pipes in area difficult to get access, implements drilling project operation, can increase existing drilling equipment drilling ability, reduce rig power consumption, reduce freight handling quality, alleviate labor strength, also can reduce difficulty of construction simultaneously, improve drilling efficiency.The formation of full aluminium light-alloy drilling rod comprises the drilling rod body of rod, female joint and male joint, and every drilling rod body of rod two ends arrange screw thread, and drilling rod body of rod upper end and female joint lower end are spirally connected, and aluminium drill pipe body of rod lower end and male joint upper end are spirally connected, and forms aluminium drill pipe single.Female joint upper end and a upper single male joint lower end are spirally connected, and so some drill pipe joints are connected to drill string.Along with the continuous increase of drilling depth, the lasting increase of work difficulty, in work progress, full aluminium light-alloy tool joint thread the phenomenon such as pulls, breaks and frequently occurs; The sealing of its screw thread flushing liquor pressure in hole weakens under raising to some extent.Therefore need double thread auxiliary structure to improve.
Utility model content
The utility model is used for solving the defect of above-mentioned prior art, and a kind of full aluminium light-alloy drilling rod that can effectively improve drilling rod anti-slip ability, good seal performance is provided.
Address the above problem adopted technical scheme as follows:
A kind of full aluminium light-alloy drilling rod, it comprises the drilling rod body of rod, female joint and male joint, wherein drilling rod body upper/lower terminal is spirally connected with female joint, male joint formation screw thread pair respectively, female joint upper end and male joint lower end form screw thread pair and are spirally connected, its special feature is: half of thread angle one side that described female joint upper end internal thread and male joint lower end external screw thread form screw thread pair is 10 °, and opposite side is-3 °.
Above-mentioned full aluminium light-alloy drilling rod, the external screw thread root of described male joint is provided with male joint sealing ring, and described drilling rod body two ends external screw thread root is equipped with drilling rod sealing ring.
Above-mentioned full aluminium light-alloy drilling rod, described male joint lower end external screw thread half of thread angle upside is-3 °, downside is 10 °.
The utility model improves for the problem that existing full aluminium light-alloy tool joint thread place easily pulls, breaks and sealing performance is not good enough, drill rod thread auxiliary structure and hermetically-sealed construction are optimized to design, by the half of thread angle of female joint upper end and male joint screw thread pair that lower end forms, by former design, be that both sides are 10 °, be improved to 10 ° of sides, opposite side is-3 °; At drilling rod body of rod two ends and male joint, rubber seal is set.Above-mentioned improvement, one side has improved the sealing performance of screw thread pair, can effectively improve on the other hand the anti-slip ability of drilling rod, and the drilling accident of reduction occurs.The utility model is improved and is developed Novel drill rod by optimization, not only can meet the demand that geology of deep part is looked for ore deposit, industry standard formulation is also had to certain reference value simultaneously.

The specific embodiment
Referring to Fig. 1, the utility model formation comprises female joint 1, the drilling rod body of rod 2 and male joint 3.The upper/lower terminal of the drilling rod body of rod 2 all arranges cylinder external screw thread; Female joint 1 lower end is provided with the cylinder internal thread being spirally connected with the drilling rod body of rod 2 upper ends, and female joint 1 upper end is provided with the conical inner screw thread being spirally connected with male joint 3 lower ends; Male joint upper end arranges the cylinder internal thread being spirally connected with the drilling rod body of rod, and male joint lower end arranges the circular cone external screw thread being spirally connected with female joint upper end.By several drilling rod bodies of rod, female joint, male joint, through screw thread pair, be mutually spirally connected and form full aluminium light-alloy drilling rod.
Referring to Fig. 5, Fig. 6, an improvement of the present utility model is, half of thread angle one side that described female joint 1 upper end conical inner screw thread and male joint 3 lower end circular cone external screw threads form screw thread pairs is 10 °, and opposite side is-3 °, and the tapering of this tapered tread pair is 1:15.As seen from Figure 6, male joint lower end external screw thread half of thread angle upside is-3 °, and downside is 10 °, and female joint upper end conical inner screw thread mates and screws with the circular cone external screw thread of male joint lower end.The male joint that the utility model is designed and female joint form the half of thread angle of screw thread pair, form a kind of hook-shaped connection that is similar between two parts that are mutually spirally connected, and can effectively improve the anti-slip ability of drilling rod, and the drilling accident of reduction occurs.
With reference to figure 1-4, another improvement of the present utility model is, at the external screw thread root of male joint 3, male joint sealing ring 5 is set, and at drilling rod body 2 two ends external screw thread roots, drilling rod sealing ring 4 is all set.The sealing effectiveness that sealing ring can improve screw thread pair is set, prevents from when flushing liquor pressure from raising revealing because sealing performance weakens mode.
