Description

Technical Field

[0001] This utility model relates to the technical field of logging filtration devices, and in particular to a light hydrocarbon logging mud filtration device. Background Technology

[0002] Continuous light hydrocarbon logging technology uses a 120-second analysis cycle to continuously detect the content of 15 hydrocarbon components (C1-nC8) in the drilling fluid. By determining the content and variation of n-alkanes, isoalkanes, cycloalkanes, and aromatics among these hydrocarbon components, it enables real-time and effective analysis of reservoir gas content, oil content, and water content during drilling, providing a valuable basis for understanding and evaluating reservoir fluid properties. During implementation, an electric mud degasser is required to quantitatively extract mud from the drilling mud tank, thereby completing mud degassing, sample gas chromatography acquisition, and data analysis.

[0025] 1. This utility model proposes a light hydrocarbon logging mud filtration device.

At the same time, the shaft drives the auger blades to rotate, causing the mud to move into the device. Simultaneously, due to the negative pressure device connected to the discharge plate, the mud inside the device diffuses outward and is filtered by the second and first filter plates respectively. When the first mud extraction and filtration is completed, the solenoid valve is opened to discharge the mud from the first and second cavities. Through the set filtration mechanism, the mud, sand and oily mud in the mud can be filtered out, thus obtaining the desired mud.

[0026] 2. The light hydrocarbon logging mud filtration device proposed in this utility model involves pressing the two second tie rods together during installation, causing the first tie rod to retract.
