Title:
MULTI-PARAMETER MEASUREMENT-WHILE-DRILLING DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/114004
Kind Code:
A1
Abstract:
A multi-parameter measurement-while-drilling device, comprising: a housing which comprises a first sleeve (100) and a second sleeve (200), wherein the second sleeve is detachably connected to an inner cavity of the first sleeve, and the second sleeve is located at a far drilling end (120) of the first sleeve; a multi-parameter acquisition module (300) which is disposed on an outer side wall of the first sleeve and used for collecting gamma, bearing, vibration and resistivity data while drilling, comprising a resistivity sensor, a gamma sensor, a bearing sensor and a vibration sensor; a circuit module which comprises a first circuit module (410) and a second circuit module (420), wherein the first circuit module is disposed in a first groove (131) on the outer side wall of the first sleeve, and the second circuit module is disposed on the second sleeve; and a transmitting antenna (500) which is used for sending data to a short receiving segment and which is disposed on a near drilling end (110) of the first sleeve. The present device determines in near real time the geography of a layer at which a drill bit is located, and has a small size and a compact structure. The present device is easy to disassemble and assemble and the production costs are low.
