Description

Ultrasonic-based solid deposition in flowline visualization apparatus and system

The present invention relates to an ultrasonic visualization-based solids integrated visualization device and system, and more particularly, to monitor the flow tubes by ultrasonic flaw detection, to detect the solids integration time of the inner wall of the flow tube, and to solidify the solid growth process according to the curing of the integrated solids The present invention relates to an ultrasound-based solids integration visualization device and system for monitoring and estimating the process of estimating the effective flow cross-sectional area in a flow tube changed by the integrated solids.

Recently, due to the impact of low oil prices and strengthening environmental regulations, the interest in the efficiency of production operation of existing oil fields is increasing rather than the development of new oil fields. Attempts are underway. Accordingly, over the past several years, the importance of monitoring and responding to predictive abnormalities at oil production sites and transportation treatment facilities has been emphasized, and related regulations are being strengthened.

Sedimentation of solids in the flow pipes leads to blockage of the flow pipes, which can lead to significant economic losses due to breakdowns and downtimes.

Visualization through internal monitoring of flow pipes in oil and gas production sites and treatment facilities, as well as in all industrial sites where flow pipes are installed, is important for flow pipe integrity assessments and oil quality assessments to detect risks that may occur in fluid flow systems.

Ultrasonic Testing (UT) is one of the most common non-destructive testing methods. It uses short wavelengths and high frequency sound waves. When a high frequency sound wave propagates into a flow tube, if a defect or internal accumulation appears, the ultrasonic wave is reflected and the time of the sound and the amplitude of the signal are measured. Most UTs use a pulse echo method.

In the 1950s, applications were extended to large inspection objects such as aircraft aircraft in the form of Ultrasonic Immersion Testing Equipment. Solid state circuits, multi-channel systems, modularization, and digital outputs were developed from 1960 to 1970. Since the 1990s, laser ultrasonic systems have been developed to facilitate non-contact remote ultrasonic inspection, and technological advances have been made, such as high-speed heating and expansion based on short laser pulses, forming seismic waves on specimens to perform inspection.

In recent years, the wireless transmission and reception system and automation are performed by using a combination of phased array and portable smart devices and applications, which is a distinguishing feature of the application of non-destructive inspection technology based on ultrasonic inspection (UT).

Detecting defects, measuring thickness, and inspecting inner walls using ultrasonic inspection (UT) are maximizing advantages in terms of technology and cost through automation and computerization. Recently, microelectronic technology, semiconductor technology, MEMS (Micro Electro Mechanical System) The adoption of technology and the application of sensor networks and artificial intelligence technologies, which are the leading technologies of the 4th Industrial Revolution, are trying to speed up the inspection process and automate image analysis, and there is a technical trend toward miniaturization and portability.

Wave types used in the ultrasonic scanning method include longitudinal waves, shear waves, rayleigh waves, lamb waves, and guided waves. Longitudinal waves are used to push the molecules of the test object in the same direction as the movement of the wave and to test the front and back ends of the flow tube body or to test the integrity of the plate before processing into the flow tube. Shear waves propagate at slower and shorter wavelengths than longitudinal waves at the same frequency, have transverse particle motion in the horizontal and vertical directions, and are commonly used to test the transverse health of a test subject. Rayleigh waves are a type of surface wave of a test object and are used to detect surface cracks of the test object. The lamb wave is a vibration that occurs from the upper surface to the lower surface of the test object, so it is also called a plate wave and is mainly used to test the position and state of discontinuity of the test object.

Patent document 1 generates an ultrasonic wave in a structure by radiating a laser beam while scanning the structure and simultaneously sensing ultrasonic waves propagating in the thickness direction from the structure to generate a thickness direction ultrasonic wave propagation image, whereby full-area pulse-echo laser ultrasonic wave propagation. Disclosed is a full-area ultrasonic wave imaging system capable of visualizing damage information in the thickness direction of an entire structure through imaging.

In addition, as a representative case of actual flow tube monitoring based on ultrasonic flaw detection methods, ENI, Italy, has developed and applied vibro-acoustic based e-vpms® for remote monitoring of oil flow tubes. It analyzes acoustic and acoustic waves generated by fluctuations in the flow rate along the pipeline using separate networks of pressure sensors and vibration sensors installed in the flow pipe at a distance of several tens of kilometers. In other words, although the monitoring technology to detect the leakage of the flow pipe is proposed by applying MAS (multi-point acoustic sensing) technology, it provides the effective flow cross-sectional information and the image information of the solid accumulation type due to the solids accumulated on the inner wall of the flow pipe. I couldn't.

Weatherford, USA, developed an ultrasonic corrosion and crack detection system for remote monitoring of flow tubes, and attempted to detect stress, corrosion and crack points through ultrasonic sensors in the flow tubes. It is possible to evaluate the integrity of the flow tube with UTWM (Ultrasonic Wall Measurement) and UTCD (Ultrasonic Crack Detection) technology, but it is not possible to grasp the effective flow cross-sectional area change and accumulation type information in the flow pipe due to solids accumulation. Small diameter flow tubes have limitations that are difficult to apply.

Malaysia's state-owned oil company, PETRONAS, has investigated the technology of wax accumulation monitoring in a flow tube using Electrical Capacitance Tomography (ECT). This visualized the wax formation in the static state of crude oil produced in the Malay Basin. However, the visualization method using electric capacitance tomography (ECT) is very dependent on the permittivity distribution of the components in the electric capacitance sensor and the resolution is somewhat low, so the phase boundary distinction in the flow tube is not clear and the sensor is placed inside and outside the flow tube. There is a limitation that all must be attached.

TRACERCO in the UK used gamma ray tomography to study monitoring technology in the presence of water and hydrates in a flow tube. Through this, we tried to measure the amount of hydrate accumulation in the flow tube and to suggest the optimized interval and inhibitor injection cycle of the site. However, X-ray tomography, including r-ray tomography, Nuclear magnetic resonance (NMR) tomography and Attenuated total reflection-Fourier transform infrared spectroscopy, ATR Imaging technology with -FTIR spectroscopy is very expensive and risks radiation exposure.

As such, in the related art, a monitoring technique for detecting a leak of a flow tube has been proposed, but a technique for providing effective flow cross-sectional information and image information in a form of solid accumulation due to solids accumulated on the inner wall of the flow tube has not been proposed.

In addition, the monitoring technology using electric capacitance tomography has been proposed, but the boundary of the boundary in the flow tube is unclear, and there is a limit that the sensor should be attached inside and outside the flow tube.

In addition, a monitoring technique using gamma ray tomography has been proposed, but the device price is very expensive and there is a risk of radiation exposure.
