Research on Signal Transmission Device of Multi Adaptive Coiled Tube Measurement and Control System

Abstract

As an important technology for oilfield development and oil and gas reservoir reconstruction, the demand for coiled tubing logging, perforating, fracturing and acidizing and other process operations has increased dramatically, and downhole testing and control operations must be completed through downhole data acquisition and transmission and control signals. However, at present, the special cable coiled tubing roller device and logging roller operating machine mainly used at home and abroad have problems such as single function, high cost, complex structure, and poor versatility. Therefore, based on the structural characteristics of the conventional coiled tubing machine, through the analysis of the existing coiled tubing testing and control data signal transmission system, the research and design of the signal transmission device for the multi adaptive coiled tubing measurement and control system was completed, and a kind of signal transmission device for the multi adaptive coiled tubing signal testing, acquisition, transmission and feedback control system with strong versatility and high transmission efficiency was studied and designed, It eliminates the high cost of traditional equipment customized processing and manufacturing and the high labor intensity of operation and maintenance operations caused by the single adaptability of operation process, which are caused by complicated structures. It is of great significance for realizing the transformation and upgrading of the multi-function of intelligent measurement and control integration of coiled tubing machine, and is extremely important for the innovation of the digital network real-time monitoring system for future oilfield development.
