Tungsten Filament Scanning Electron Microscope | SEM2000

The CIQTEK SEM2000 is a fundamental and versatile analytical tungsten filament scanning electron microscope with 20 kV resolution up to 3.9 nm and support for upgrading to 30 kV, allowing observation of microstructural information of sub-microscale samples.

It has a more extensive range of motion than a desktop/benchtop SEM. It is suitable for rapid screening of samples and has more expansion interfaces for BSED, EDS/EDX, and other accessories to enable a broader range of applications.

  • Resolution
    3.9 nm @ 20 kV
  • Acceleration Voltage
    0.5 ~ 20 kV (30 kV optional)
  • Magnification
    1 ~ 300,000x

Versatile Detectors

High-sensitivity Backscatter Detector

· Multi-channel imaging

The detector has a compact design and high sensitivity. With a 4-segmentation design, there is no need to tilt the sample to obtain shadow images in different directions as well as composition distribution images.

 

 

· Comparison of secondary electron (SE) imaging and backscattered electron (BSE) imaging

In the backscattered electron imaging mode, the charge effect is significantly diminished and more information on the composition of the sample surface can be obtained.

near-bit follow-on measurement system

In January 2022, the CatLiD-I 675 near-bit follow-on measurement system provided by CIQTEK-QOILTECH achieved a successful operation well in the Linxingzhong gas field located at the transition location between the Yishaan slope and the Jinxi flexural fold zone in the Ordos Basin, which the related parties well recognized. The lithology of the top and bottom of the seam of the target layer of this well is mainly mudstone and carbonaceous mudstone. The coal seam is buried at a large depth, and there is less reference data available in the surrounding wells. The coal seam section is prone to wall collapse and well leakage, downhole stuck drilling, buried drilling, and other complicated accidents. Moreover, the well slope adjustment is large due to landing advance. The CIQTEK-QOILTECH CatLiD-I 675 near bit was picked up from 2208 m and the retest curve matched the upper instrumentation, providing data for guidance to give an accurate landing point.     When landing, due to the advancement of the coal seam, the trajectory goes down to the bottom of the coal seam, and the gamma curve of the near bit measures the complete curve pattern of the coal seam from the top to the bottom, which provides a basis for judging the position of the borehole trajectory inside the coal seam later. The gamma curve change of near bit in drilling is obvious with high resolution and accurately judges the position in and out of the coal seam and within the coal seam. The accurate change of the value of gangue in the coal seam can effectively determine the location of the trajectory, which improves the drilling encounter rate and smoothness of the borehole trajectory.     The service section of this well is 2208-3208m, with cumulative footage of 1000m and a drilling encounter rate of 91.7%; a trip to drill to completion depth, with a cumulative downhole time of 168 hours, 53.5 hours of pure drilling, and an average mechanical drilling speed of 18.69m/h, which greatly shortens the drilling cycle! The on-site crews of CIQTEK-QOILTECH and related teams worked together to shorten the drilling cycle, increase the drilling encounter rate, reduce the risk, and finally received high praise from everyone! The CIQTEK-QOILTECH CatLiD-I 675 near-bit measurement system is a perfect completion.
