Mwd System Yhd2-1000 (A)

[Application scope and technical characteristics]
YHD2-1000(A) measurement while drilling system (MWD) consists of explosion-proof laptop, real-time survey tool and trajectory control software. Real-time survey data can be recorded displayed and storage during drilling process.

With real-time drilling data, portable data tools, and more, YHD2-1000(A) boosts operator success and overall efficiency. It allows drillers to drill more footage faster, while ensuring the hole is always on plan. Trajectory control software allows the driller to see exactly where the borehole is compared to the borehole plan, with specified tolerances, allowing for accurate borehole placement. Down-hole real time survey tool is powered by the laptop instead of down-hole battery, which will reduce operation cost and increase its service life. Additional gamma sensor can be deployed if necessary (additional fees will be added), which can help drillers to stay in-seam and reduce the number of sidetracks drilled, saving time and money.

Overall, YHD2-1000(A) is all about efficiency, from the driller all the way to the project manager. It offers cost saving benefits that will give driller exact trajectory control and additional cost saving over the success of the drilling project.


[Technical scope]
1.Suitable for underground environment of coal mine with explosive mixture of methane and coal dust and corrosive gas without damaging insulation.
2.Applicable to the directional drilling track while drilling survey operation along the coal seam, high roof, comb shaped roof and floor, drainage, grouting and reinforcement of roof and floor, exploration of hidden disaster causing factors, fire fighting and rescue.
3.Suitable for sliding directional drilling and composite drilling.

[Function]
1.Data acquisition function: the device has the function of acquisition of drilling track parameters, including inclination, azimuth and tool face angle;
2.Storage function: the device has the storage function of drilling track parameters (dip angle, azimuth angle and tool face angle);
3.Display function: When the computer is turned on and running the MWD software, it can display the parameters of drilling trajectory (inclination, azimuth and tool face angle) in real time; When the computer is turned on and running the MWD software, it can display the drilling design track and actual drilling track in the plan and profile.
