See now accompanying drawing, wherein, parts similar in each figure are represented by similar Reference numeral, immediately with reference to Fig. 1, this figure be schematically illustrated level to the elevation of an embodiment of well system, it is generally represented and is manufactured according to the disclosure by Reference numeral 10.Although illustrated system demonstrates the invention to buried for carrying out (inground) drilling operation in the framework of well system and parts thereof in level, the present invention is applicable to other operating procedure on an equal basis, includes but not limited to vertical drilling operation, for the pullback operation of installation, mapping operation etc.
Fig. 1 shows the system 10 of operation in region 12.System 10 comprises rig 14, and rig 14 has the drill string 16 that extends to boring tool 20 from rig.Drill string can be pushed in ground so that buried instrument 20 moves towards the forward direction 22 shown in arrow at least substantially.Although this example is constructed from the use of boring tool, be to be understood that discussion herein can be applicable to the buried instrument of any appropriate format, include but not limited to fraising instrument, can installation or the pullback operation of shell during the tension force monitoring tools, the surveying and mapping tool for the path of boring is surveyed and drawn that use, for example, use inertial guidance unit and drilling pressure monitoring downwards.In the operation of boring tool, expectation is monitored based on coming in before drill string conventionally, and in such as other operations such as pullback operation, conventionally in response to the retraction of drill string, carries out monitoring.
Continuation is with reference to Fig. 1, and drill string 16 partly shown and be segmented, and drill string 16 consists of a plurality of attached, individual drill pipe section removedly with segment length or partial-length and wall thickness, some drill pipe section with 1,2, n-1 and n represent.Drill pipe section is called as the drilling rod with pole length interchangeably.In rig operating period, can once a drill pipe section be added on drill string and movable balladeur train 30 pushes drill pipe section in ground by rig, thereby buried instrument is advanced.Rig 14 can comprise suitable watch-dog 32, it is for measuring drill string to the movement on ground, the United States Patent (USP) 6 that this is called in for example name " SYSTEMS; ARRANGEMENTS AND ASSOCIATED METHODS FOR TRACKING AND/OR GUIDING AN UNDERGROUND BORING TOOL(follows the trail of and/or guide system, device and the correlation technique of buried boring tool) ", 035, ' 951 patent that 951(hereinafter referred to as) in, describe to some extent, this United States Patent (USP) and the application are common all and this United States Patent (USP) is incorporated to herein by reference.
Each drill pipe section is limited with the through hole 34(extending between the opposite end of pipeline section and illustrates one).Drill pipe section can be equipped with so-called case accessory and pin accessory, and every one end of predetermined drill pipe section can both be threadedly engaged with the adjacent end portion of another drill pipe section in known manner and drill string.Once being joined together, drill pipe section forms drill string, the through-hole alignment of adjacent drill pipe section and form overall channel 36 as shown by arrows.Passage 36 can provide the supercharging of drilling fluid consistent with the direction of arrow 36 from rig to drill bit or mud to flow, and will be further described below.
Can at rig 14 places, (for example on console 42, use display 44) and establish and show boring tool in 12Zhong position, region and buried path that boring tool is followed.Console can comprise treatment facility 46 and control actuator device 47.
Boring tool 20 can comprise drill bit 50, and drill bit 50 has for turn to the inclined-plane of (steer) based on rolling orientation.That is to say, when being pushed away forward without spin time, the drill bit rolling orientation based on its inclined-plane and deflection conventionally.On the other hand, conventionally, by making drill string be promoted to rotate, make drill bit straightaway as shown in double-headed arrow 51.Certainly, measurable turning to be take suitable edaphic condition as prerequisite.Note, aforementioned drilling fluid can be under high pressure as jet 52 ejections, for stinging the soil that is through drill bit dead ahead and the Cooling and Lubricator that drill bit is provided.Boring tool 20 comprises buried housing 54, and buried housing 54 is received electron device package part 56.Buried housing is configured to drill bit 50 stream through electron device package part is provided, and this will find out in the accompanying drawing below.In one embodiment, electron device package part can and be supported in housing 54 for cylindrical configuration.Drill bit 50 can comprise the pin accessory of being received by the case accessory of buried housing 54.The opposite end of buried housing can comprise that case accessory receives the pin accessory of drill pipe section n, and this pin accessory limits the buried end in distally of drill string.Certainly, drill bit 50 can substitute with having such as fraising instrument, the fraising instrument of being combined with tension force watch-dog, mapping equipment or its any suitable buried instrument with pin accessory such as appropriately combined.It should be noted, the pipe fitting of drill bit and buried housing is generally those case accessories and corresponding case accessory and the pin accessory of pin accessory (drill pipe section is attached removedly each other for helping when forming drill string) common in the drill pipe section with drill string.Therefore, buried housing 54 can with such as buried tool engagement such as drill bits 50, drill bit 50 there is pin accessory and have simultaneously for drill string buried/relative case accessory that distal end portion engages removedly.For buried housing 54 being inserted into the object (reason is described hereinafter) in drill string, can use box pin adapter (not shown), thereby make case accessory 114 be applicable to being assembled to pin accessory.In this respect, it should be noted, box pin accessory adapter is well known in the art.In another embodiment that will describe, buried housing can comprise case accessory and relative pin accessory.
Buried electron device package part 56 can comprise transceiver 64, and in certain embodiments, transceiver can send such as the framing signals such as dipole locating signal 66, but this not necessarily.In certain embodiments, transceiver 64 can receive the electromagnetic signal being generated by other buried parts, below will describe at suitable place.For purposes of illustration, this example is the framing signal of dipole signal form by hypothesis electromagnetic signal.Therefore, electromagnetic signal can be described as framing signal.Should be understood that, dipole signal can be modulated as any other electromagnetic signal, and can from signal, recover modulating data subsequently.The positioning function of signal depends on character shape and the signal strength signal intensity thereof of flux field (flux field) at least in part, and does not depend on the ability of its delivery modulation signal.Therefore, do not need modulation.The information for example, with some parameters (, pitching and rolling (orientation parameter), temperature and drilling fluid pressure) of boring tool relevant can utilize the suitable sensing equipment 68(that forms an electron device package part part can comprise pitch sensor (pitch sensor) for example, roll sensor (roll sensor), temperature pick up, for any other sensor of AC field sensor, the DC magnetic field sensor of going off course directed for sensing and the expectation of the approximate 50/60Hz utility line of sensing) measure.Electron device package part 56 also comprises processor 70, and processor 70 is connected with transceiver 64 with sensing equipment 68 when needed.Another sensor that can form a sensing equipment part is following accelerometer: this accelerator is configured to detect the acceleration on one or more axles.Can provide electric power with battery 72.
