AI Technical Summary
Existing technologies for extracting organic-clay complexes from shale are ineffective and have poor detection accuracy. Suspension extraction is not effective for non-black shale with low organic matter content, while acid washing destroys the complex structure. Fixed wavelet threshold denoising results in signal distortion or poor performance.
Organic clay composites were extracted using a suspension extraction method combined with low-temperature drying technology. Particle size was controlled by ultrasonic dispersion and long-term low-frequency wet milling. Denoising was performed by adaptive correction of wavelet threshold using discrete wavelet transform, and X-ray diffraction and infrared spectroscopy analysis were also conducted.
This method improves the accuracy of extraction, preparation, and detection of organoclay complexes, avoids mechanical damage and signal distortion, and ensures the precision of detection results.
