Performance of MWD influence measurement result

Nov 30, 2016

In order to solve the problems of deep well measurement while drilling with high temperature and high pressure, MWD are improved in the aspects of probing tube assembly, connect combination insulating material, cable cap, anti-pressure tube, insulating Pipe, insulator, heat receiver and space plug etc. Also it must be used with anti-temp cable together when it works in the high temperature well.


MWD can 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.
