Wireless Measurement-While-Drilling (MWD) System- Power Generation Model(WMWD-01A)
Wireless Measurement –While-Drilling (MWD-01A) System, developed by ASIT Co., Ltd., is a kind of drilling direction system with positive pulse and self-generated power.
Introduction

Wireless Measurement –While-Drilling (MWD-01A) System, developed by ASIT Co., Ltd., is a kind of drilling direction system with positive pulse and self-generated power. The system adopts the quartz flexible accelerometers and fluxgate sensor, which are developed for petroleum drilling by ASIT Co., Ltd., and realizes accurate measurement of trajectory parameters. The system may transmit real-time downhole parameters to the ground system by mud pulse transmission technology.

Therefore the system can be used to provide real-time, accurate operation basis for directional well.

Characteristic

High measuring accuracy, good long-term stability, calibration cycle of more than 1000 h (downhole working time).

Anti-interference and adaptable, uses the advanced soft/hardware fusion filtering technology, greatly improves instrument decoding ability.

Based on space technology, high reliability, and keep improving the idea of implementing product research &development and manufacturing.

With short message function, realizes timely communication between the instrument room and drilling platform.

Good scalability and can articulate well depth system and gamma sub, realizes natural gamma measurement of the geological parameters

Have the remote transmission function of measuring information.
