The drilling direction and well track of the well type such as well, has the advantages that real-time height, fast response time, good reliability, is Directional Drilling
The TRAJECTORY CONTROL of well provides foundation.Overcoming existing continuous pipe drilling well measurement while drilling field does not have to be measured under production wells in real time
The deficiency of the instrument of parameter.
The technical solution used in the present invention is：A kind of continuous pipe drilling well measurement while drilling instrument, including sleeve and positioning connect
Head；Screwed connection landing nipple in sleeve lower end is simultaneously sealed by sealing ring, and cable enters sleeve inner, the cable core of cable lower
It is connected with copper post by fixing screws, copper post lower end is connected with circuit board by crossover sub I, cable outer sheath is equipped with electricity
Cable crossover sub skeleton, cable crossover sub skeleton lower end are connected by screw insulation sleeve, and insulation sleeve is sleeved on copper post and cable
The outside of the cable core of lower end, cable crossover sub skeleton upper end are set with wiper block, cable crossover sub skeleton lower end outside
Cable crossover sub outer tube is connected by screw, cable crossover sub outer tube is sleeved on the outside of insulation sleeve, circuit board is by conversion
Joint II is connected with inserting tube, and circuit board is arranged in resistance to compression cylinder, inserting tube lower end threaded connection spline joint, spline joint lower end
Pass through bonded with landing nipple, circuit board includes supply module, signal acquisition module, signal processing module and signal transmission mould
Block, is packaged with sensor in inserting tube.
The invention has the beneficial effects as follows：Present invention achieves during continuous pipe directional drilling Real-time Collection hole deviation, side
The downhole parameters such as position, tool-face, magnetic field intensity, can be manipulated by computer on ground, easy to be reliable, be easy to more accurate
Drilling direction and well track that continuous pipe bores the well type such as sidetracked hole, sidetrack horizontal well, directional well are monitored reliably, with real-time
Property height, fast response time, the advantage of good reliability, the TRAJECTORY CONTROL for directed drilling provide foundation.
