Abstract

The invention belongs to the field of deepwater leakage detection, and particularly relates to a deepwater process facility acoustic emission detection device which comprises an external compression resistance device and an internal acoustic emission detection system. The compression resistance device comprises a cylinder body, a spherical-crown-shaped end socket, a flat-cover end socket and a fixing device, wherein the cylinder body is a streamline cylindrical pressure-resistant shell; the spherical-crown-shaped end socket is provided with a watertight plug connector to achieve power supply and signal transmission, and hanging rings are welded to facilitate fixing and carrying; the flat-cover end socket realizes compression resistance and good signal transmission; O-shaped sealing rings are designed between the end sockets and the cylinder body to realize sealing; an adjustable hoop structure is designed to be fixed to technological facilities of different shapes and sizes; the acoustic emission detection system comprises an acoustic emission sensor, a signal transmission cable and a signal processor, wherein the acoustic emission sensor collects and amplifies signals, and the signal processor displays, processes and analyzes data. The device has the advantages of pressure resistance, water resistance, good signal transmission, reasonable design, high applicability and capability of realizing leakage detection of deepwater process facilities.

Description

Technical field [0001] The invention belongs to a deep water leakage detection device, and particularly relates to the design of an acoustic emission detection device for deep water process facilities. Background technique [0002] In recent years, driven by energy demand, oil and gas exploration has gradually shifted from land to ocean, and the amount of offshore oil and gas extraction has gradually increased. Deepwater oil and gas exploitation process facilities are the main components of offshore oil and gas field development and production systems. Ensuring the normal operation of deepwater process facilities is the key to ensuring offshore oil and gas exploitation. [0003] However, the environment of the seabed is more complicated than that of the land, resulting in the long-term dynamic change of the engineering geological environment for deep-water process facilities, and the outside is more susceptible to damage and interference by various factors. For example, withstand...
