Abstract
The utility model discloses a drilling rod is clear away to polygon detritus bed mainly comprises male joint, female joint, drilling tool body, middle part support area, drilling tool water hole. The maximum diameter of the drilling tool body is smaller than the diameters of the male joint and the female joint, and is also smaller than the diameter of the middle supporting belt; the drilling tool body is of a polygonal structure, and the appearance of the drilling tool body is of a regular hexagon structure, a regular octagon structure or a regular decagon structure. The method has the function of solving the problem of removing the detritus bed of the extended reach well and the long horizontal section horizontal well. Because polygon body structure compares in circular drilling rod, can play better stirring effect to the drilling fluid to improve the detritus bed and clear away the effect.
Description
Technical Field
The utility model belongs to the technical field of the oil drilling and specifically relates to a drilling rod is clear away to polygon detritus bed.
background
In the drilling process of the petroleum industry, the formation of the detritus bed can not avoid the occurrence of the detritus bed, and particularly in the construction process of a large displacement well and a long horizontal section horizontal well, the formation of the detritus bed can lead to the increase of friction resistance torque slightly, and the formation of the detritus bed can lead to the unsmooth tripping and even the occurrence of underground drill jamming accidents, so that the research on the detritus bed clearing tool has important significance.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming prior art not enough, provide one kind and can play better stirring effect to the drilling fluid to improve the detritus bed and clear away the effect, solve the polygon detritus bed of the difficult problem that the big displacement well, long horizontal segment horizontal well detritus bed were clear away and clear away the drilling rod.
The technical scheme of the utility model as follows:
The utility model provides a drilling rod is clear away to polygon detritus bed, includes drilling tool body and connects female joint, the male joint at drilling tool body both ends to and run through the drilling tool water hole of drilling tool body, wherein: the outer section of the drilling tool body is polygonal, and the maximum outer diameter of the drilling tool body is smaller than the outer diameters of the female connector and the male connector.
The above scheme further comprises:
The outer section of the drilling tool body is a regular polygon.
The outer cross section of the drilling tool body is a regular hexagon, a regular octagon or a regular decagon, and the polygonal obtuse angle of the drilling tool body is arc-shaped.
A middle supporting belt is arranged on the drilling tool body between the female joint and the male joint.
The middle supporting belt is one or more sections, and the total length is 50-150 cm.
The female joint, the male joint and the middle support band have the same outer diameter.
The utility model discloses an advantage: (1) the regular polygon drilling tool body can better stir drilling fluid in the process of rotating at the bottom of a well, so that the aim of removing a detritus bed is fulfilled; (2) the middle supporting belt is arranged, so that the polygonal body can be prevented from contacting the well wall as far as possible and causing damage to the well wall; (3) the device has the characteristics of simple structure, low cost, good rock debris bed clearing effect and no damage to the well wall.

Figure 2 is the enlarged schematic view of the cross-section of the drilling tool body of the polygonal detritus bed clearing drill rod of the utility model.
The labels in the figure are: 1. female joint, 2, drilling tool body, 3, middle support band, 4, male joint, 5, drilling tool water hole.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, a polygonal detritus bed removal drill rod comprises a drill body 2, and a female joint 1, a male joint 4 connected at both ends of the drill body, and a drill water hole 5 penetrating through the drill body, wherein: the outer section of the drilling tool body 2 is polygonal, and the maximum outer diameter of the drilling tool body 2 is smaller than the outer diameters of the female connector 1 and the male connector 4.
Further:
The outer section of the drilling tool body 2 is a regular polygon.
The outer section of the drilling tool body 2 is a regular hexagon, a regular octagon or a regular decagon, and the polygonal obtuse angle of the drilling tool body 2 is arc-shaped.
a middle supporting belt 3 is arranged on the drilling tool body 2 between the female joint 1 and the male joint 4.
The middle supporting belt 3 is one or more sections, and the total length is 50-150 cm.
The female joint 1, the male joint 4 and the middle support band 3 have the same outer diameter.
Typical examples are as follows:
Compare attached 1 and 2, the utility model provides a drilling rod is clear away to polygon detritus bed includes female joint 1, drilling tool body 2, middle part support area 3, male joint 4 and drilling tool water hole 5.
Referring to fig. 2, the drill body 2 has a polygonal cross-section with a drill port 5 at the center, and the drill body 2 is preferably a regular hexagon, a regular octagon or a regular decagon. The regular polygon drilling tool body can well stir drilling fluid in the rotation process of the well bottom, so that the aim of removing a rock debris bed is fulfilled. The appearance of the drilling tool body is a regular hexagon, a regular octagon or a regular decagon, the smaller the number of sides is, the stronger the stirring capacity of the drilling tool body on drilling fluid is, but the wall thickness is easy to thin due to the limitation of the inner diameter of a drill rod, if a drill rod with the common phi 127mm weight is taken as an example, when the outer diameter phi 127mm and the inner diameter phi 76.2mm of the drilling tool body are kept unchanged, the thinnest wall thickness of the processed regular hexagon drill rod is 16.89mm, the drilling tool body still has higher strength, and the requirements of site construction can be met. The diamond corner part of the drilling tool body is processed by the obtuse arc, so that the polygonal drilling tool body 2 can be prevented from damaging the well wall, the larger wall thickness can be ensured under the condition that the outer diameter is not larger than the outer diameter of the joint, and the strength of the drilling tool body is improved.
The female joint 1, the male joint 4 and the middle supporting belt 3 of the drilling tool have the same outer diameter, so that the polygonal drilling tool body 2 is prevented from damaging the well wall. The length of the middle support belt is 50-150cm, so that good support is ensured when the bent well section and the drilling tool are subjected to large lateral force.
