The specific embodiment
In the utility model, directional tool is made up of downhole instrument and ground installation two large divisions.Wherein, downhole instrument comprises the contact unit of inserting tube assembly, the guide shoe of sitting key, guide shoe adjustment retaining mechanism, stube cable, the parts such as hawser head assembly that lifting discharges instrument.Ground installation comprises parts such as driller's display, special-purpose computer, well depth system and the cable that matches, adapter.
With reference to Fig. 1, Fig. 1 is the structural representation of inserting tube assembly in this directional tool.The inserting tube assembly is made of upper plug head assembly 11, measurement assembly 12, resistance to compression tube 13 and lower end cap assembly 14.Wherein, measure the inside that assembly 12 is installed in resistance to compression tube 13, resistance to compression tube 13 is for example for bearing the titanium alloy resistance to compression tube of down-hole 100MPa high pressure.An end of measuring assembly 12 is connected with upper plug head assembly 11, and the other end is connected with lower end cap assembly 14.Especially, upper plug head assembly 11, lower end cap assembly 14 are sealed in the two ends of resistance to compression tube 13 respectively.Like this, the inserting tube assembly has been realized brand-new integrated design.
Among this embodiment, measuring assembly 12 is cores of a whole set of instrument.Different fully with available technology adopting magnetic liquid suspension accelerometer, measure assembly 12 and select for use the high quartz accelerometer of resistance to shock, thereby improved the certainty of measurement of instrument as the acceleration of gravity meter.With reference to Fig. 2, Fig. 2 shows the local structure for amplifying of measuring assembly 12.It comprises fluxgate 21, circuit board 22 and the quartz accelerometer 23 that is installed on the stage body.Here, fluxgate 21 preferred three axis fluxgates that adopt.Compare with adopting the uniaxial magnetic open gate, the former obvious integrated level height, compact conformation, it is little to take volume, helps saving the space.
By measuring the quartz accelerometer 23 and the fluxgate 21 of assembly 12, the inserting tube assembly detects acceleration of gravity and earth magnetism respectively at inserting tube stage body X, Y, the Z component on axially.When sensor detects its input quantity, together input quantity is transformed into corresponding with it output voltage with servo circuit, through certain displacement and computing, obtain directioin parameters such as hole deviation, orientation, tool-face again.
After tested, among this embodiment, the performance indications that directional tool reaches at work are as shown in the table:
And in the prior art, the performance indications of directional tool are generally, hole deviation: ± 0.2 °; Orientation: ± 1.5 °; Tool-face: ± 1.5 °.To those skilled in the art, advantage of the present utility model is obvious.
For shortening the total length of instrument, the utility model adopts the contact to connect the replacement telephone cable.For example, upper plug head assembly 11 can be made of one group of contact assembly and upper plug head with the tool housing insulation.Upper plug head one end connects resistance to compression tube 13, and the sealing of resistance to compression tube 13 is provided, and the other end connects contact unit, draws data wire.
Preferably, lower end cap assembly 14 is made of longitudinal vibration damper and lower end cap.Lower end cap one end connects resistance to compression tube 13, and the sealing of resistance to compression tube 13 is provided, and the other end connects parts such as extension bar, connecting rod, lock sleeve, guide shoe.And an end of measuring assembly 12 is connected with lower end cap assembly 14 by longitudinal vibration damper, and the other end is connected with upper plug head assembly 11 by contact assembly.
Especially, longitudinal vibration damper can preferably adopt rubber, metal composite axial buffer device.Not only can improve shock resistance like this, and shorten axial dimension greatly.In addition upper plug head with measure assembly be connected employing and the similar contact structure of contact unit, so, not only axial dimension further reduces, and dismounting, also greatly change of assembly process process.According to the utility model, the length of inclinometer probe assembly only has about 830mm, compares with existing like product, has shortened closely 45%, and effect is fairly obvious.
In order to make instrument can bear radially mechanical oscillation, keep stable, and reduce its unnecessary damage, the utility model adopts the design of combined radial vibration damping to realize the resistance to shock requirement of instrument especially.Particularly, can two groups of radially damping assemblies be installed on the stage body of assembly 12 measuring, measure the two ends of assembly 12 and respectively establish one group, make itself and the inwall maintenance appropriate gap of resistance to compression tube 13.
