Title:
PORTABLE INTELLIGENT LOW-DISTURBANCE SAMPLING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/026961
Kind Code:
A1
Abstract:
A portable intelligent low-disturbance sampling apparatus, comprising a power supply device (1), a low-disturbance water pumping device, a packer device, a downhole monitoring device, a true value determination and sampling device (2), and an automatic controller (3). The low-disturbance water pumping device comprises a sampling pump (5), a sampling pipe (6), a cable (7) and a frequency conversion controller (8), and is used for completing a low-disturbance underground water sampling task; the true value determination and sampling device (2) is used for enabling water sample circulation and determining whether a collected water sample is a real formation water sample; the downhole monitoring device is used for measuring downhole water level and water temperature data; the low-disturbance water pumping device, the downhole monitoring device, and the true value determination and sampling device (2) all need to be connected to the power supply device (1) by means of the automatic controller (3) via the cable (7) or a data line. The sampling device causes little disturbance to an underground aquifer, can satisfy the collection requirements for test samples such as inorganic components, organic components, microorganisms, and dissolved oxygen, and has a true value determination function to analyze parameters such as TDS, PH and dissolved oxygen of a water sample.
