APPLICATIONS:
- Identification of geological structure, such as fractures, unconformities and faults.
- To determine the occurrence of crack and its development direction and determine the direction of the maximum horizontal principal stress.
- Detection of sleeve corrosion condition
- Detection of sleeve deformation condition and location.
- To distinguish the formation lithology and to determine the occurrence of formation
- Stability and ground stress analysis of wellbore and foundation pit
INTRODUCTIONS:
The three-dimensional borehole integrity detector uses a rotary sonar to scan the wall of a borehole and record the return echo waveform. Changes in the acoustic impedance of the rock will affect echo amplitude and changes in the hole diameter will affect the propagation time of the echo. The reflection wave amplitude and propagation time measured in the borehole are displayed as images at a 360°azimuth so as to obtain high-resolution imaging of the entire borehole. Such imaging can provide reliable geological foundation data for engineering exploration, including the pore size variation, fracture width, dip angle, azimuth and distribution of caverns. With the help of sonar image, information like the location of perforation or the damage to the sleeve caused by the construction and production can be obtained so as to provide information for the well maintenance.
FEATURES:
- Fully intelligent design, built-in electronic compass, fully automatic rotary scanning, high detection efficiency
- Compared with traditional imaging, sonar scanning has richer information, higher resolution and more intuitive and more convenient for analysis and judgment
- Real-time automatic generation of 3D inspection results report
- The instrument and probe is small in size and easy-to-carry
