ERMWD is a combination of domestic and international characteristics of the existing MWD, brainstorm, and easy to learn to understand the positive pulse MWD wireless inclinometer. The instrument applies to the up-hanging, under-sitting-key the two forms of pulse generator, and both are the mechanism prevention of the key taken off. If configure a specialized screw and short section. The instrument can achieve the measurement while drilling of near-bit deviation angle.
