A kind of continuous pipe drilling well measurement while drilling tool

Technical field:

The present invention relates to a kind of continuous pipe drilling well underground supporting tool, in particular to a kind of continuous pipe drilling well measurement while drilling work Tool.

Background technique:

It is common technology in drilling engineering with brill technology, is widely used in directional well, horizontal well and sidetrack horizontal well In equal drilling wells, commonly it is divided into wired drilling and two kinds of wireless drilling.

Continuous pipe drilling well is drilling technology developed in recent years, carries out wellbore construction, difference using continuous tube apparatus In conventional drilling, continuous pipe drilling well needs mating dedicated downhole tool, applies in continuous pipe drilling well and is also classified into brill technology Wired drilling and wireless drilling, wireless drilling with it is essentially identical used in conventional drilling, wired drilling needs to seal sensor In with drill tools, together with other continuous piping tools lower going-into-well bottom together, in drilling process using cable and ground into Row communication, realizes the downhole parameters such as real-time display hole deviation, orientation and tool-face.However the country is at present to continuous pipe drilling well with driller The research of tool aspect also belongs to blank.

Summary of the invention:

The technical problem to be solved in the present invention is to provide a kind of continuous pipe drilling well measurement while drilling tool, the arrangement achieves The downhole parameters such as hole deviation, orientation, tool-face, magnetic field strength are acquired in real time during continuous pipe directional drilling, can be passed through on ground Computer is manipulated, easy to be reliable, reliably monitors continuous pipe brill sidetracked hole, sidetrack horizontal well, orientation convenient for more accurate The drilling direction and well track of the well type such as well have the advantages that real-time height, fast response time, good reliability, are Directional Drilling The TRAJECTORY CONTROL of well provides foundation.Overcoming existing continuous pipe drilling well measurement while drilling field can not be under real-time measurement production wells The deficiency of the tool of parameter.

The technical solution used in the present invention is: a kind of continuous pipe drilling well measurement while drilling tool, 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 by fixing screws with copper post, copper post lower end is connected by crossover sub I with circuit board, and cable outer sheath is equipped with electricity Cable crossover sub skeleton, cable crossover sub skeleton lower end are connected by screw to 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 It is connected by screw to cable crossover sub outer cylinder, for cable crossover sub outer sleeve on the outside of insulation sleeve, circuit board passes through conversion Connector II is connected with inserting tube, and circuit board is mounted in resistance to compression cylinder, and inserting tube lower thread connects spline joint, spline joint lower end It is connected by key with landing nipple, circuit board includes power supply module, signal acquisition module, signal processing module and signal transmission mould Block is packaged with sensor in inserting tube.

The beneficial effects of the present invention are: the present invention is realized acquires hole deviation, side during continuous pipe directional drilling in real time The downhole parameters such as position, tool-face, magnetic field strength can be manipulated on ground by computer, easy to be reliable, convenient for more accurate Drilling direction and well track that continuous pipe bores the well type such as sidetracked hole, sidetrack horizontal well, directional well are reliably monitored, is had real-time The advantages of property height, fast response time, good reliability, foundation is provided for the TRAJECTORY CONTROL of directed drilling.

Detailed description of the invention:

The present invention will be further described in detail with reference to the accompanying drawings and detailed description.

Fig. 1 is the structural diagram of the present invention.

Specific embodiment:

As shown in Figure 1, a kind of continuous pipe drilling well measurement while drilling tool, including sleeve 1 and landing nipple 14;Sleeve 1 is pipe Shape part, 1 upper end of sleeve are connected with upper tool string, and 1 lower end screwed connection landing nipple 14 of sleeve is simultaneously close by sealing ring 16 Envelope, cable 2 enter inside sleeve 1, and the cable core of 2 lower end of cable is connected by fixing screws 17 with copper post 7,7 lower end of copper post It is connected by crossover sub I 9 with circuit board 10,2 outer sheath of cable is equipped with cable crossover sub skeleton 5, cable crossover sub 5 lower end of skeleton connects insulation sleeve 6 by screw 15, and insulation sleeve 6 is sleeved on the outside of the cable core of 2 lower end of copper post 7 and cable, absolutely Copper post 7 and cable core are isolated from the outside by edge set 6.5 upper end of cable crossover sub skeleton is set with wiper block 3, and wiper block 3 plays Support effect placed in the middle.5 lower end outside of cable crossover sub skeleton passes through 15 connecting cable crossover sub outer cylinder 4 of screw, cable Crossover sub outer cylinder 4 is sleeved on 6 outside of insulation sleeve, and circuit board 10 is connected by crossover sub II 11 with inserting tube 12, circuit board 10 are mounted in resistance to compression cylinder 8, and resistance to compression cylinder 8 plays a part of protection circuit plate 10.12 lower thread of inserting tube connects spline joint 13, 13 lower end of spline joint is connected by key with landing nipple 14, rotate inserting tube 12 cannot in sleeve 1, prevents the tool of measurement Face parameter is inaccurate.Circuit board 10 includes power supply module, signal acquisition module, signal processing module and signal transmission module, inserting tube Sensor is packaged in 12.

By the way of cable communication, power supply is carried out with communicating through cable 2 present invention.Circuit board 10 includes power supply mould Block, signal acquisition module, signal processing module and signal transmission module, wherein the voltage that power supply module transmits cable 2 is converted To give signal acquisition module, signal processing module and signal transmission module and sensor on circuit board 10 after voltage needed for circuit Power supply, the telecommunications of the downhole parameters such as hole deviation, orientation, tool-face, temperature, magnetic field strength that signal acquisition module obtains sensor Be sent to signal processing module after number acquisition, signal processing module signal is encoded by transport protocol after by signal transmission Module transfer is to host computer.Sensor is in real time by parameters such as hole deviation, orientation, tool-face, temperature, magnetic field strengths in drilling process Electric signal is converted to, sensor is connect by crossover sub II 11 with circuit board 10.
