Abstract
Description
- This invention relates in general to drilling systems, and, in particular, to a horizontal directional drilling system. More specifically, but without restriction to the particular embodiments hereinafter described, this invention relates to a horizontal directional drilling system, wherein the drilling is fast, and the energy consumption may be optimized to be minimum.
- Horizontal directional drilling systems using percussive tools to make a borehole without disturbing the above ground surface are known in the art. The percussive tool provides percussive energy to a hammer. The drill bit is connected to the hammer and receives the percussive energy from the hammer. They are advantageous in many aspects but restricted to a limited range of operations, e.g. due to not being steerable.
- Conventional steerable horizontal drilling systems comprise a dual-member drill string and a drilling tool connectable with the dual-member drill string. The dual-member drill string comprises an inner member and an outer member, where the inner member is independently rotatable of the outer member. The inner member of the dual-member drill string drives operation of the drilling tool.
- U.S. Pat. No. 6,761,231 discloses a steerable drilling tool adapted to receive rotational energy from the inner member of a dual-member drill string. In a preferred embodiment the drilling tool has a hydraulic pump, driven by a drive member, to operate the drill assembly. In another preferred embodiment the drilling tool has a rotary-driven cam assembly adapted to mechanically operate the drill assembly. This invention provides steerable control in horizontal directional drilling operations, but presents numerous disadvantages, e.g. complex and costly interconnections.
- Use of hydraulic pump or a cam assembly to operate the hammer does not provide optimization of the process of making a borehole. Thus, horizontal directional drilling systems utilizing hydraulic pumps or cam assembly to operate the drilling are characterized by relatively high cost and relatively low productivity as the system is slow.
- It is an object of the invention to eliminate or at least minimize the above mentioned problem which is achieved by means of a horizontal directional drilling system in accordance with the appended claims.
- Thanks to the invention there is provided a horizontal directional drilling system that is surprisingly fast, easy to operate, relatively inexpensive and which at the same time provides the synergetic effect of consuming a relatively low amount of energy.
- Further advantages and aspects of the invention will be prepared in the following part of the description.
- Further objects of the present invention together with additional features contributing thereto and advantages accruing therefrom, will be apparent from the following description of the a preferred embodiment of the invention which is shown in the accompanying drawing with like reference numerals indicating like components throughout, wherein:

In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more embodiments. It may be evident, however, that such embodiments may be practiced without these specific details.
-
FIG. 1 illustrates a horizontal directional drilling system in accordance with an embodiment of the invention. The horizontal directional drilling system may be used to make aborehole 6, without disturbing an above ground structure. The horizontal directional drilling system comprisesrotary drive systems 4, 5 on amoveable base 13, anearth anchor 11, a dual string 1 andequipment rotary drive systems 4, 5equipment - In a preferred embodiment, the dual string 1 comprises standardized sections of an inner string (not shown) coaxially fitted within an
outer string 3. The length of each section is normally about 4.5 m. The dual string 1 is operatively connected to the independentrotary drive systems 4, 5 at a first end. Therotary drive system 4 drives the inner string. The rotary drive system 5 drives theouter string 3. - A
front casing 7 is fitted to the most distal section of the dual string 1. Thefront casing 7 is operatively connected to ahammer 9. The length 1 2 of thecasing 7 is normally within the range of 0.5-2 m. The drill string 1 transmits torque and thrust to thehammer 9 to fracture the subterranean formation. Thehammer 9 generates percussive energy using pressurized air supplied through an annular passage between the inner string and theouter string 3 of the dual string 1. - The
earth anchor 11 is driven into the earth to stabilize aframe 13 against the axial force exerted by therotary drive systems 4, 5 during advancement of thehammer 9. -
FIG. 2 illustrates an enlargement of the encircled area shown inFIG. 1 . As illustrated in the enlarged view ofFIG. 2 , the inner string 2 is in the form of a tube/pipe having acentral bore 20 to enable transportation of working fluid there through to thehammer 9. Eachouter string 3 is connected toanother string 3 by means ofconical threads hexagonal couplings outer string 3 are connectable with the inner strings 2 and theouter strings 3 of adjacent dual string sections to form the dual string 1. - The interconnected inner string 2 and
outer string 3 rotate independent of each other. Therotary drive system 4 used to rotate the interconnected inner string 2, drives thehammer 9. - The
front casing 7 is arranged to be easily fitted to the most distalouter string 3 with a kind of arrangement similar to theconical threads 31 used to connect eachouter string 3 to anotherstring 3. The length 1 2 of thefront casing 7 is about 1.2 m. At about half the length of thefront casing 7 there is abend 70 to arrange for an angle α, about 1-3° of anend part 71 of thefront casing 7. This angle α of theend part 71 permits easy steering of thehammer 9 through theborehole 6. The length of thehammer 9 is normally in the range 1-2 m, which together with the bent portion of the casing will provide a considerable displacement of thehammer head 90 despite the use of a small angle α at the same time as it allows for straight forward drilling without problems. - A
drive shaft 8, that extends in one integral part, is operatively engaged with the inner string 2 at afirst end 22 with a kind of arrangement similar to thehexagonal connection 22 used to rotationally lock theinner strings 3 to each other. At theother end 71 of theintegral shaft 8 there is a fitting for thehammer 9. The workingmedium 10 is transported to thehammer 9 using a space between an external wall of thedrive shaft 8 and the internal wall of thefront casing 7. - Referring now to
FIG. 3 , there is shown a preferred embodiment of thedrive shaft 8 engaged with the inner string 2. Thedrive shaft 8 has aninlet channel 80 with a dimension for e.g. φ=13 mm, that is larger than the dimension of an inlet channel of a standard conventional drive shaft. Similarly, theoutlet channel 82 has a dimension larger than the outlet channel of a standard conventional drive shaft, for e.g. φ=13 mm Further, three radially extendingtransfer holes outlet channel 82. The diameter within the section 85 with theholes standard drive shaft 8, for e.g. 70 mm - The
inlet channel 80 comprises anopening 81 so that the workingmedium 10 entering theinlet channel 80 may move out of theinlet channel 80. -
FIG. 4 illustrates thefront casing 7 in accordance to a preferred embodiment herein. Thebend 70 arranges for an angle α, about 1-3° of theend part 71 to enable steering of thehammer 9 through theborehole 6. Thefront casing 7 comprises anopening 79 to receive a positioning sensor. Thus, the steering of thehammer 9 may be performed in a controller manner, as the positioning sensor provides the position/direction of thehammer 9 at an instance. -
FIG. 5 illustrates the arrangement of thedrive shaft 8 and thefront casing 7 in more detail. As illustrated, thedrive shaft 8 is accurately positioned coaxially with theend part 71 of thefront casing 7, by means of a plurality ofbearings 75. As a consequence thedrive shaft 8 will flex to be slightly curved within thefront casing 7, to achieve an ability to steer the direction R1 of thehammer 9, as shown inFIG. 2 , when theouter string 3 is not rotated. - Referring still to
FIG. 5 , aseal 76 is arranged to totally seal thebearings 75 from the influence of the workingmedium 10 within the space in thefront casing 7. Apositioning sensor 77 is fixed on anopening 79 on thefront casing 7, through a sealedlid 78. The drilling operation may be securely controlled by means of thepositioning sensor 77. Thehexagonal connection 22 operatively engages thedrive shaft 8 with the inner string 2. - The working medium supplied through the
inlet channel 80 is transported to the spacing betweendrive shaft 8 and thefront casing 7 through theopening 81. The workingmedium 10 in the spacing between thedrive shaft 8 and thefront casing 7 enters theoutlet channel 82 through the three radially extendingtransfer holes hammer 9 from theoutlet channel 82. - Referring now to
FIG. 2 ,FIG. 3 , andFIG. 5 , during straight forward drilling, both theouter string 3 and the inner string 2 are rotated, which will form a straight line borehole, i.e., proceed in the direction of the dual string 1 centre R2. When a change of direction is desired, theouter string 3 is fixed in a position to have the direction R1 of thehammer 9 to work in a desired direction, which is sensed and controlled by means of theposition sensor 77. - During change of direction of the
borehole 6, the inner string 2 is continuously rotated and thehammer 9 is active. Theouter string 3 is not rotated and only pushed together with the inner string 2, until the desired direction is achieved. Thus, thereinafter both the inner string 2 and theouter string 3 are rotated. -
FIG. 6 illustrates thehammer 9 in more detail. Thehammer 9 is a standard conventional product known per se (supplied by Alpha Laval) in a preferred embodiment. A conically threadedattachment part 92 connects thehammer 9 to thefront casing 7. By supplying pressurized air to thehammer 9, thedrill head 90 performs percussions/blows to improve drill speed. The percussions/blows from thedrill head 90 are received by adrill tooth 91. As a result thedrill tooth 91 penetrates the soil by a certain increment of displacement. - Thanks to the percussions/blows performed by the
drill head 90 using the supply of pressurized air, the process of making theborehole 6 using the horizontal directional drilling system in accordance with the invention is optimized to obtain minimum energy consumption. Further, the drilling process in accordance with the invention is faster than conventional horizontal drilling methods. - While this invention has been described in detail with reference to a (certain) preferred embodiments, it should be appreciated that the present invention is not limited to those precise embodiments. Rather, in view of the present disclosure which describes the current best mode for practicing the invention, many modifications and variations would present themselves, to those of skill in the art without departing from the scope and spirit of this invention. For instance, it is evident to the skilled person that the advantages of the principles of the invention may also be achieved when using other fluids than air to obtain the percussive action, e.g. water, nitrogen or any other suitable gas or liquid depending on circumstances. Also, despite the fact that merely horizontal drilling is described above, it is evident that the principles of the invention may be used for other kind of drilling operations. The scope of the invention is, therefore, indicated by the following claims rather than by the foregoing description. All changes, modifications, and variations coming within the meaning and range of equivalency of the claims are to be considered within their scope. As is evident for the skilled person the principle according to the invention may be applied within a wide range of different dimensions of the hammer and the casing. However, preferably a not too large drill hole is produced in merely one step. Instead a kind of standardized dimension for performing a first hole, in a first step, with the steerable drilling is chosen, e.g. using a diameter of the hammer within the range of 5-10 inches, more preferred using a hammer of about 6 inches. In a subsequent step a plurality of different kind of traditional equipment may be used to expand the drill hole to a larger, desired size. The advantages is that the same kind of steerable drill equipment may be used to produce many different sized drill holes and that a less complex drilling action (with or without dual string) can be used in the final drill step. The subsequent enlargement of the drill hole may be performed by the use of various types of traditional drill equipment and if a pneumatic hammer is used by a single line, which for example may be pulled backwards through the first drill hole. Also of course traditional hammers and/or drill tools may be used where a pushing action is used. As is also evident some kind of protruding steering device (centralizer), to exactly follow the first drill hole, may be applied to the drill tool that shall expand the first drill hole. In some cases it may be possible to in fact use the same drilling equipment to also pull the bigger drilling tool through the hole backwards, which of course then will provide some further advantages, i.e. easier logistics, etc.
