Description of drawings
Fig. 1 is the structural representation of the wire line coring drilling rod of prior art;
Fig. 2 is the structural representation after the utility model drilling rod connects;
Fig. 3 is a structural representation of the present utility model;
Embodiment
As Fig. 1 is the connected mode of the wire line coring drilling rod of prior art, being connected by hermaphrodite connector (2,3) between drilling rod 1 and the drilling rod 4.
As Fig. 2 is direct-connected deep hole wire line coring drilling rod, includes drilling rod main body 6, is male thread 5 and box thread 7 at drilling rod main body two, adopts direct-connected the connection between drilling rod and the drilling rod.Improvement of the present utility model is embodied in the following aspects: 1. the drilling rod connected mode and with 2. 3. drill rod thread structural design etc. of drilling rod whole heat treatment process of the drill rod end jumping-up technology of join dependency.
1, selection innovation
The domestic 45MnMoB that always is to use of wire line coring drilling rod.By material analysis, heat treatment test, direct-connected deep hole wire line coring drilling rod is selected the modified alloy steel of high-quality (30CrMnSiA) for use.Its physical and mechanical properties of modified back surpasses 45MnMoB widely.Part index number meets or exceeds external like product.
2, structure innovation
(1) common wire line coring drilling rod external diameter φ 71mm, internal diameter φ 61mm, the utility model drilling rod external diameter φ 71mm, internal diameter φ 62mm or external diameter φ 89mm, internal diameter φ 79mm.Its drill pipe thickness has reduced 0.5mm, weight saving 9%, and when deep well drilling, the rig consumed power is little, and during lifting, the lifter load is little, can promote the dark ability of brill of rig;
(2) connecting between drilling rod and the drilling rod is direct-connected, drilling rod of common core plugging notifying mechanism of rope core drilling has 6 head threads, direct-connected deep hole wire line coring drilling rod has only two head threads, be male thread and box thread, simple in structure, reduce 2/3 male and female catcher interface, reduced accident rate, significantly reduced the probability of drill rod breaking; In addition, adopt direct-connected the connection between drilling rod and the drilling rod, improved the right alignment between the drilling rod;
(3) drill pipe thickness attenuation, whole drilling rod weight saving, the drill rod end threaded portion is thickeied, and has improved the intensity of screw thread, and the two combines, and has improved the dark ability of brill of drilling tool widely.Drilling rod adopts two jumping-up, and the critical section area of stressed maximum has increased 25%～30%.The inside and outside jumping-up position transition of drilling rod is mild, and no step has been eliminated the clamping stagnation when inner tube assembly extracts and throws in drilling rod, reduced the pressure loss of washing fluid, strengthened rock dust on return ability, reduced the possibility of bit freezing simultaneously.
(4) drill rod thread length is 50, and depth of threat 1mm, pin thread tapering are 1: 20, and the box tapering is 1: 22, and threaded portion intensity is strengthened like this, and drilling rod is also fine to neutrality.
3, manufacturing process innovation
Drilling rod adopts bulk heat treatmet, has given full play to the potential of material.Drilling rod after the thermal treatment is higher more than 25% than 45MnMoB strength degree, high nearly one times of yield limit.Drilling rod adopts high-quality quenched and tempered steel, by the modified thermal treatment of integral body, has improved the hardness and the rigidity of drilling rod, thereby has improved drilling rod twisting strength and edurance beding strength, tensile strength and wearing quality greatly.
