Problems solved by technology

However, in addition to the additional supporting drum, in addition to increasing the expensive construction cost, the coiled tubing on the hydraulic motor driven drum used on site needs to be poured out during construction, and then re-coiled on the special drum, so the workload is very large

Abstract

The invention discloses a coiled tubing vehicle and a roller device and a rotary joint thereof, and the rotary joint comprises a coiled tubing external connection T-shaped short section, a cable core, a cable clamp, a rotary joint body, a slip ring assembly, a swivel joint and a sealing device; the rotary joint body is used for connecting a roller shaft; treating fluid can sequentially flow through the rotary joint, the rotary joint body and the liquid inlet end of the coiled tubing external connection T-shaped short section; one end of the cable clamp is connected to the outlet end of the coiled tubing external T-shaped nipple, and the other end is connected with a coiled tubing; the cable core is matched with the slip ring assembly, and the cable core penetrates through the wire inlet end and the outlet end to be matched with the cable clamp; the sealing device is arranged between the wire inlet end of the coiled tubing externally-connected T-shaped short section and the cable core. According to the scheme, the treating fluid can be pumped for well repair construction, the monitoring signal data of the logging instrument at the bottom of the coiled tubing can be transmitted to the ground, wired logging is achieved, and the purposes of reducing labor intensity and lowering construction cost are achieved.

Description

technical field [0001] The invention relates to the technical field of coiled tubing cable logging equipment, in particular to a coiled tubing vehicle, a drum device, and a rotary joint. Background technique [0002] Coiled tubing is a continuous flexible steel pipe with a diameter of generally 1 to 2 inches and a length of 2000 to 7000m. The coiled tubing is coiled on a large winding drum. When it is lowered into the oil well, it passes through the center of the winding drum A high-pressure rotary joint pumps the treatment fluid into the tubing, makes the drum rotate, releases the coiled tubing from the winding drum, and then passes it through a gooseneck guide to straighten the coiled tubing and lower it into the wellbore; After the operation, the flexible coiled tubing is pulled out of the well and rewound on the winding drum. Since the tubing is continuous, there is no need to connect it during running into the oil well, and it can maintain continuous circulation during...
