Abstract

The invention provides a device and a compatible method of a coiled tubing inlet analysis software. The input terminals of the AI input module and the pulse input module in the device are connected with the probe on the front-end equipment by a data line, The output end is connected with the input end of the PLC controller by the data line, the output end of the PLC controller is connected with the CAN bus communication module by the data line, and the other two input ends of the CAN bus communication module are connected with the LCD touch screen and the wireless router by the data line. Themethod comprises the following steps: 1, connecting each hardware; 2, the running and debugging of each hardware; 3, constructing a running database; 4, constructing a program module; 5. Compatibilitybetween self-made database and tubing inlet analysis software; 6. Data analysis. The device and method can realize on-line and off-line data fatigue analysis, realize localization of acquisition system in coiled tubing software, and realize seamless link between localization acquisition system and imported fatigue analysis software.

Description

technical field [0001] The invention relates to computers and related application fields, in particular to a device and a compatible method for analysis software of a coiled tubing inlet. Background technique [0002] The software for coiled tubing operations basically includes: imported coiled tubing acquisition system and imported tubing fatigue analysis software. At present, the coiled tubing acquisition system is basically domestically produced, and the fatigue analysis software still uses foreign software. When the coiled tubing is released and entangled on the drum of the coiled tubing machine, and goes in and out of the wellbore around the gooseneck, the plastic deformation of the coiled tubing will occur. , repeated bending will cause the coiled tubing to be fatigued and eventually damaged. With the accumulation of fatigue, the yield strength of the coiled tubing will gradually decrease. Especially in high pressure operation, the decrease of yield strength will redu...

AI Technical Summary

Problems solved by technology

At present, the coiled tubing acquisition system is basically gradually localized, and the fatigue analysis software still uses foreign software. When the coiled tubing is released and entangled on the drum of the coiled tubing machine, and goes in and out of the wellbore around the gooseneck, the plastic deformation of the coiled tubing will occur. , repeated bending will cause the coiled tubing to fatigue and eventually be damaged. With the accumulation of fatigue, the yield strength of the coiled tubing will gradually decrease

Especially in high-pressure operation, the decrease of yield strength will reduce the ability of coiled tubing to resist collapsing and rupture under axial, radial and hoop pressure, which will lead to permanent elongation and even tubing fracture to block the oil well
