Coiled Tubing Tools
Products Descripiton:
The centralizer is a tool connected in the tool string and used for preventing the tool string from fleeing upwards. It can be separately connected with the underground instrument release and placed underground, or connected at the upper part of the downhole tool string.
Technical parameters:
1.Outer diameter: 1.5″/1.875″
2.Fishing neck: 1.375″/1.5 ″
3.Applicable oil pipe scope: 2 7/8″ 3 1/2 ″
4.Connecting thread: 15/16″-10UN.P×B / 1 1/16″-10UN.P×B
Products Descripiton:
The cutter is mainly composed of an upper joint, a mandril, a spring, a guide cylinder, an upper cylinder, a lower cylinder, a nozzle supporting cylinder, a nozzle, a tool bit and the like. The steel ball is placed into the tool mandril in advance, the tool bit correspondingly extendss forwards and is unfolded while jacking the inclined edge as the water pressure pumped into the pipe is increased; the longer the tool bit extends forwards, the larger the tool bit is unfolded; when the cutter is unfolded to a certain degree, the mandril on the lower plug jacks the steel ball, the pressure is discharged from the ball seat, and the tool bit does not extend forwards.
Technical parameters:
1. Outer diameter: ∅54mm
2. Minimal inner diameter: ∅19.1mm
3. Length: 922mm
4. Connecting thread at the upper end
5. Scope of cutting oil pipe: 2 7/8＂～3 1/2＂
Products Descripiton:
The double baffle check valve has a complete sealing system, and two levels of baffle valves are independent with each other and are used for preventing the pressure at the well bottom from fleeing upwards when the string is gone down or taken back.
Technical parameters:
1. Outer diameter: ∅54mm
2. Minimal inner diameter: ∅20.5mm
3. Length: 282mm
4. Connecting thread at the lower end: 1 27/32-12SA
Products Descripiton:
The double circulation valve is composed of a valve body, a piston, a shearing pin and a rupture disk. The dual circulating valve provides two ways for building a circulation from the oil pipe to the annular hole. In the downhole state, the steel ball is directly pressed to build the circulation; or when the downhole drilling tool assembly is blocked to lose the circulation, the rupture disk will be fractured by too high pressure, so that the small circulating channel is built, and then the steel ball is delivered to build the full circulation channel.
Technical parameters:
1.Outer diameter: ∅54mm
2.Minimal inner diameter: ∅14.2mm
3.Length: 234mm
4.Connecting thread at the upper end：1 27/32-12SA
5.Connecting thread at the lower end: 1 1/2MT
Products Descripiton:
It mainly plays a role in connecting the coiled tubing with the tool string.
Technical parameters:
1.Outer diameter: ∅54mm
2.Minimal inner diameter: ∅20.7mm
3.Applicable oil pipe: ∅38.1
4.Length: 369mm
5.Connecting thread at the lower end: 1 27/32-12SA

2.Minimal inner diameter: ∅20.7mm
3.Applicable oil pipe: ∅38.1mm
4.Length: 369mm
5.Connecting thread at the lower end: 1 27/32-12SA
Products Descripiton:
This tool is used for clamping the opened clamping jaw on the inner wall of the oil pipe after the pressing during the oil pipe cutting operation, and then a certain pressure is downwards applied, and the clamping jaw is firmly clamped on the pipe wall to center and cut the tool stably when the oil pipe is cut. Under the condition that the pressure is undone, the clamping jaw is tightly clamped and is not retracted, the tool string is released by lifting the tool at this moment, and the clamping jaw will be retracted after being released.
Technical parameters:
1.Outer diameter: ∅52.4mm
2.Minimal inner diameter: ∅15.88mm
3.Length: 841mm
4.Connecting thread at the upper and lower end: 1 1/2MT.BXP
5.Maximum inner diameter of clamping jaw: ∅62mm
Products Descripiton:
The well washing tool is mainly composed of a connecting joint, a rod body, a washing head, a needle roller thrust bearing, etc. The tool can rotationally wash the paraffin, rust, silt and other impurities adhered to the pipe wall, and can automatically and rotationally wash the pipe wall by hydraulic power after the pressing.
Technical parameters:
1.Outer diameter: φ57.2mm
2.Length: 439mm
3.Shapes of upper and lower connection buckles: 1 1/2MT
4.Applicable oil pipe: 2 7/8＂～5 1/2＂
