Abstract

The invention discloses a tubing string vibration monitoring and integrity diagnosis technology for oil and gas wells, and relates to the technical field of oil and gas wells. The technology includesa front-end acquisition device, a data acquisition module, a database server and a monitoring and maintenance integration module. The front-end acquisition device adopts NI cDAQ-9188, and the data istransmitted to a data acquisition end or a data acquisition platform. The monitoring and maintenance integration module is connected with the data acquisition module and the database server through local connection LAN connection or WAN connection. The monitoring and maintenance integration module and the database server communicate through the database remote access technology. The monitoring andmaintenance integration module and the acquisition module communicate through a TCP/IP. According to the invention, the actual parameters, amplitude, frequency, displacement and acceleration of the vibration of the downhole tubing string are acquired through actual detection technology. The technology has a great guiding significance for production.

Description

Technical field [0001] The invention relates to the technical field of oil and gas wells, and in particular to a technique for monitoring and diagnosing the integrity of an oil and gas well tubing string. Background technique [0002] Tubing string is one of the key pipe tools used extensively in the process of oil and gas generation, and it is a necessary passage connecting the bottom layer and the ground. The tubing string is connected by tubing. As long as any tubing breaks and fails, the normal production of oil and gas wells will be interrupted or even serious accidents will occur, causing harm to people's lives and property. The current string mechanics systematically gives the analysis methods for the axial buckling performance, axial deformation, load and strength safety of the completion string, and gives the completion packer performance during the completion and long-term production process. Force, sealing performance and integrity theory and experimental analysis met...
