Abstract
The utility model relates to a drill pipe used in production of oil field industry, in particular to an integral typed drill pipe with the body forming of an end part, which comprises a connecting maternal joint for the drill pipe (1), a drill pipe body (3) and a connecting paternal joint for the drill pipe(4). The integral typed drill pipe with body forming of the end part is designed according to the production demand and after being processed and treated, the forming part of the end part has the completely same materials as the materials of the body of the drill pipe. The drill pipe has the advantages of having a great improvement in aspects of concentricity, tensile strength, sealing performance, etc., saving production cost, and being suitable to the drill pipe bodies of varying materials, varying specifications and varying lengths.
Description
Technical field
The utility model relates to the drilling rod that the oil field industrial production is used, especially: a kind of integral drill rod of end body moulding.
Prior art
At present, the drilling rod that the oil field industrial production is used all adopts friction-welding technique, tool joint and drilling rod body are welded as a whole, realize being connected between drilling rod and the drilling rod, but not body monolithic moulding, this method has been continued to use decades so far, can not guarantee that tool joint material and drilling rod body material are in full accord, has reduced the tensile strength between tool joint and drilling rod body; Especially in the development of drilling technology, advanced drilling technology and method are extensively used, adopt the drilling rod of traditional friction-welding technique processing low in hot strength, problems such as concentricity is poor, poor sealing performance are difficult to meet the needs of production, and better the drilling rod product also never occurs.
Summary of the invention
The goal of the invention of the integral drill rod of a kind of end body moulding of the utility model is: the integral drill rod that a kind of end body moulding is provided, under the situation that does not increase drilling rod body wall thickness, after utilizing drill rod end body partial operation moulding, PROCESS FOR TREATMENT becomes the drilling rod jointing of integral drill rod, pass through PROCESS FOR TREATMENT again, make end moulding section and drilling rod body material in full accord; This drilling rod has had powerful raising at aspects such as concentricity, tensile strength, sealing performancies; To achieve these goals, the integral drill rod of a kind of end body moulding of the utility model is achieved in that a kind of integral drill rod of end body moulding, by: drilling rod connects female, the drilling rod body is connected male with drilling rod and forms; It is characterized in that: drilling rod connects female, drilling rod connection male is that one is processed to form on the drilling rod body, and the material of drilling rod connection female, drilling rod connection male and drilling rod body is in full accord; On the drilling rod body between drilling rod connection female, the drilling rod connection male, directly be processed with and connect the transition body; Wherein, drilling rod connects female and is connected male with drilling rod and can suitably increases length according to the use needs, guarantee a kind of end body moulding integral drill rod reparation and repeatedly recycle; A kind of integral drill rod of end body moulding is according to producing the needs design, and is in full accord through processing processing rearward end moulding section and drilling rod body material; This drilling rod has had powerful raising at aspects such as concentricity, tensile strength, sealing performancies, has satisfied the production needs, has reduced cost of production, has reduced construction hidden danger; Be specially adapted to the drilling rod body of various materials, all size, all lengths.
Description of drawings
Accompanying drawing is a kind of half sectional view of integral drill rod of end body moulding.
The specific embodiment
Below with reference to the accompanying drawings (as shown in the figure) the utility model is described further: a kind of integral drill rod of end body moulding, by: drilling rod connect female 1, drilling rod body 3 is connected male 4 and forms with drilling rod; At first, processing drilling rod body 3, the drilling rod that connects connect female 1 and are connected male 4 with drilling rod on the drilling rod body, make drilling rod body 3 and the drilling rod connection female 1 that is connected be connected the material of male 4 with drilling rod in full accord; And then on the drilling rod body 3 between drilling rod connection female 1 and the drilling rod connection male 4, directly process connection transition body 2, last process is processed into the geometry external form of standard, is convenient to produce lift; Wherein, drilling rod connect female 1 is connected male 4 with drilling rod can be according to the needs increase length of using, be used for guaranteeing a kind of end body moulding integral drill rod repeatedly reparation and recycle.
Claims (1)
1. the integral drill rod of an end body moulding, by: drilling rod connects female (1), drilling rod body (3) is connected male (4) and forms with drilling rod; It is characterized in that: drilling rod connection female (1) is connected male (4) with drilling rod be to go up one at drilling rod body (3) to be processed to form, and the material of drilling rod connection female (1), drilling rod connection male (4) and drilling rod body (3) is in full accord; Connecting female (1) at drilling rod is connected with drilling rod on the drilling rod body (3) between the male (4) and directly is processed with connection transition body (2).
