Description
FLEXIBLE HOSE WITH THRUSTERS FOR HORIZONTAL WELL DRILLING
This application claims the benefit of U.S. Provisional Patent Application Serial No. 60/195,076 filed April 6, 2000.
FIELD OF THE INVENTION
The invention relates to horizontal well drilling and more particularly to a flexible hose assembly for horizontal well drilling.
BACKGROUND OF THE INVENTION In the process of drilling for hydrocarbons such as oil and natural gas, vertical wells have been used most often in the past. Those wells will produce for a given amount of time, then begin to dry up. At that point, it is advantageous to drill out horizontally from the vertical well in order to try and increase production of, for example, crude oil. There have been several attempts to find an economically viable and reliable system for drilling into the untapped pay zones adjacent an existing vertical well. Horizontal drilling has been proposed as an alternative and has been described in U.S. Patent Nos. 5,853,056, 5,413,184, 5,934,390, 5,553,680, 5,165,491, 5,458,209, 5,210,533, 5,194,859, 5,439,066, 5,148,877, 5,987,385, 5,899,958, 5,892,460, 5,528,566, 4,947,944, 4,646,831, 4,786,874, 5,410,303, 5,318,121, 4,007,797, 5,687,806, 4,640,362, 5,394,951, 1,904,819, 2,521,976 and Re. 35,386, the contents of all of which are incorporated herein by reference. U.S. Patent No. 5,413,184 describes a method of horizontal drilling which utilizes flexible hose and a high pressure nozzle blaster to bore into the earth's strata at significant depths, such as 4000 feet. The nozzle uses high pressure water to clear a path through the strata. The nozzle is advanced through the strata by applying weight to the hose, i.e., slacking off the tension in the vertical portion of the hose. Essentially, the weight of the 4000 feet of hose above
the nozzle is used to apply pressure to the nozzle, thus forcing it along the horizontal path. While this method is effective at significant depths due to the large amount of weight available,- it is less effective at shallower depths. At shallow depths, there simply is not enough weight available to supply sufficient force to advance the nozzle blaster through the strata. Thus, there is a need for an apparatus that will effectively advance a drilling tool such as a nozzle blaster horizontally through the earth's strata for horizontal drilling at shallow depths.
SUMMARY OF THE INVENTION A flexible hose assembly for horizontal well drilling is provided. The hose assembly comprises a flexible hose and a nozzle blaster attached to the hose. The hose has a plurality of holes disposed therein, each of which is adapted to direct pressurized aqueous liquid in a direction forming an angle less than 80° with the longitudinal axis of the hose in an upstream direction from the location of the hole. A method of horizontal well drilling is also provided which includes the steps of: providing a flexible hose assembly having a nozzle blaster at one end of a flexible hose, and at least one thruster coupling with a plurality of holes disposed about its circumference; lowering the hose assembly to a desired depth in a vertical well, and redirecting the hose assembly along a substantially horizontal direction, substantially perpendicular to the longitudinal axis of the vertical well; forcing at lest 2,000 psi aqueous liquid through the hose, the nozzle blaster and the holes in the couplings; and drilling a bore substantially horizontally into the earth's strata adjacent the vertical well.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS OF THE INVENTION In the description that follows, when a preferred range such as 5 to 25 (or 5-25) is given, this means preferably at least 5, and separately and independently, preferably not more than, or less than, 25. As used herein, the following terms having the following meanings: "gal/min" means gallons per minute and "psi" means pounds per square inch. The invention can be used with respect to oil wells, natural gas wells, water wells, solution mining wells, and other wells. The invention includes a flexible hose assembly comprising a flexible hose with thrusters and a nozzle blaster for horizontal well drilling. The hose assembly is fed down into the bore of an existing vertical well to a specified depth, at which point it is redirected along a horizontal direction, substantially perpendicular to the vertical well. Preferably, the hose assembly is fed into the well by a coil tubing injector as known in the art. Redirection of the hose assembly is accomplished via an elbow or shoe in upset tubing as is known in the art, less preferably via some other known means. The hose is supplied with a plurality of thruster couplings disposed along the length of the hose. Each coupling contains one or more thrusters, each thruster comprising a hole through the coupling wall, to allow the passage of water therethrough. The holes are oriented in a substantially rearward direction about the circumference of
the coupling such that high pressure water exits the holes at a substantially rearward angle, and enters the horizontal bore in a direction sufficient to impinge upon the walls of the bore, thus thrusting the hose (and thereby the nozzle blaster) forward through the bore. With reference to Fig. 4, there is shown generally a flexible hose assembly 10 according to the invention, which preferably comprises a nozzle blaster 24 and a flexible hose 11. Flexible hose 11 has and comprises a plurality of flexible hose sections 22, a pair of pressure fittings 23 attached to the ends of each hose section 22, and a plurality of thruster couplings 12, each of which joins a pair of adjacent pressure fittings 23. Hose assembly 10 comprises a nozzle blaster 24 at one end and is connected to a source (not shown) of high pressure fluid, preferably an aqueous liquid, preferably water, less preferably some other liquid, at its other end. Couplings 12 are spaced at least, or not more than, 5, 10, 20, 30, 40, 50, 60, 70, 80, 90 or 100 feet apart from each other in hose 11. The total hose length is preferably at least or not more than 100 or 200 or 400 or 600 or 700 or 800 or 900 or 1000 or 1200 or 1400 or 1600 or 1800 or 2000 feet. Hose sections 22 are preferably flexible hydraulic hose known in the art, comprising a steel braided rubber-Teflon (polytetrafluoroethylene) mesh, preferably rated to withstand at least 5,000, preferably 10,000, preferably 15,000, psi water pressure. High pressure water is preferably supplied at at least 2,000, 5,000, 10,000, or 15,000 psi, or at 5,000 to 10,000 to 15,000 psi. When used to drill horizontally from a vertical well, the hose extends about or at least or not more than 7, 10, 50, 100, 200, 250, 300, 350, 400, 500 or, most preferably, 440 feet horizontally from the original vertical well. As illustrated in Fig. 1, thruster coupling 12 comprises a coupling or fitting, preferably made from metal, preferably steel, most preferably stainless steel, less preferably aluminum. Less preferably, coupling 12 is a fitting made from
plastic, thermoset, or polymeric material, able to withstand 5,000 to 10,000 to 15,000 psi of water pressure. Still less preferably, coupling 12 is a fitting made from ceramic material. Coupling 12 has two threaded end sections 16 and a middle section 14. Preferably, end sections 16 and middle section 14 are formed integrally as a single solid part or fitting. Threaded sections 16 are female-threaded, so as to receive male-threaded pressure fittings 23 which are attached to, preferably crimped within the ends of, hose sections 22 (Fig. 4) . Each fitting 23 has a threaded portion and a crimping portion which can be a unitary or integral piece, or a plurality of pieces joined together as known in the art. Alternatively, the threaded connections may be reversed; i.e. with male-threaded end sections 16 adapted to mate with female-threaded pressure fittings attached to hose sections 22. Less preferably, end sections 16 are adapted to mate with pressure fittings attached to the end of hose sections 22 by any known connecting means capable of providing a substantially water-tight connection at high pressure, e.g. 5,000-15,000 psi. Middle section 14 contains a plurality of holes 18 which pass through the thickness of wall 15 of coupling 12 to permit water to jet out. Coupling 12 preferably is short enough to allow hose 11 to traverse any bends or elbows in the upset tubing and any shoes or adapters used therewith. Therefore, coupling 12 is formed as short as possible, preferably having a length of less than about 3, 2, or 1.5 inches, more preferably about 1 inch or less than 1 inch. Hose 11 (and therefore couplings 12 and hose sections 22) preferably have an outer diameter of about 0.25 to about 1.25 inches, more preferably about 0.375 to about 0.5 inches, and an inner diameter preferably of about 0.125 inches. Couplings 12 have a wall thickness of preferably about 0.025- 0.25, more preferably about 0.04-0.1, inches. Optionally, hose 11 is provided with couplings 12 formed integrally therewith, or with holes 18 disposed directly in the sidewall of a contiguous, unitary, non-sectioned hose at
spaced intervals along its length. A hose so comprised obviates the need of threaded connections or other connecting means as described above. As shown in Fig. 1, holes 18 have hole axes 20 which* form an angle β with the longitudinal axis of the coupling 12. Angle β is preferably 10° to 80°, more preferably 15° to 70°, more preferably 20° to 60°, more preferably 25° to 50°, more preferably 30° to 45°, more preferably 40° to 45°, more preferably about 45°. The holes 18 are also oriented such that water passing through them exits the coupling 12 in a substantially rearward direction; i.e. in a direction that is upstream from the location of the hole, being substantially opposite the desired direction of travel of the nozzle blaster. (The desired direction of travel of the nozzle blaster is indicated by arrow A in Figs. 1 and 4) . In this manner, high-pressure water jets 30 emerging from holes 18 impart drilling force to the nozzle blaster, thus forcing the nozzle blaster forward into the earth strata (see Fig. 4) . As shown in Figs. 1 and 4, each hole 18 is adapted to direct pressurized aqueous liquid in a direction forming an angle (preferably less than 80°) with the longitudinal axis of the hose in an upstream direction from the location of the hole. As illustrated in Fig. 2, a plurality of holes 18 are disposed in wall 15 around the circumference of coupling 12. There are 2 to 6 or 8 holes, more preferably 3 to 5 holes, more preferably 3 to 4 holes. Holes 18 are spaced uniformly about the circumference of coupling 12, thus forming an angle α between them. Angle α will depend upon the number of holes 18, and thus will be preferably from 45° or 60° to 180°, more preferably 72° to 120°, more preferably 90° to 120°. Holes 18 are preferably about 0.010 to 0.017 inches, more preferably 0.012 to 0.016 inches, more preferably 0.014 to 0.015 inches in diameter. As best seen in Figs. 1 and 2, holes 18 are formed in the wall 15 of coupling 12, extending in a substantially rearward
direction relative to direction A, connecting inner opening 17 at the inner surface of wall 15 with outer opening 19 at the outer surface of wall 15. The number of couplings 12, as well as the number and size of holes 18 depends upon the desired water pressure and water flow rate. If a water source of only moderate delivery pressure is available, e.g. 5,000-7,000 psi, then relatively fewer couplings 12 and holes 18, as well as possibly smaller diameter holes 18 should be used. However, if higher pressure water is supplied initially, e.g. 10,000- 15,000 psi, then more couplings 12 and holes 18 can be _ utilized. The number of couplings 12 and holes 18, the diameter of holes 18, and the initial water pressure and flow rate are all adjusted to achieve water flow rates through nozzle blaster 24 of 1.5-5, more preferably 2-3.5, more preferably 2.5-3, gal/min. Nozzle blaster 24 is of any type known in the art, for example, the type shown in Figs. 5A-5B. Nozzle blaster 24 comprises a plurality of holes 50 disposed about a front portion 46a which preferably has a substantially domed shape. Holes 50 are positioned so as to form angle θ with the longitudinal axis of nozzle blaster 24. Angle θ is 10°-30°, more preferably 15°-25°, more preferably about 20°. Nozzle blaster 24 also comprises a plurality of holes 46b, which are oriented in a reverse direction on a rear portion 60 of nozzle blaster 24, the direction and diameter of holes 46b being similar to that of holes 18 disposed around couplings 12. Holes 46b serve a similar function as holes 18 to impart forward drilling force to nozzle blaster 24. Optionally, front portion 46a is rotatably coupled to rear portion 60, with holes 50 oriented at an angle such that exiting high- pressure water imparts rotational momentum to front portion 46a, thus causing front portion 46a to rotate while drilling. Rear portion 60 is either fixed with respect to hose 11, unable to rotate, or is rotatably coupled to hose 11, thus allowing rear portion 60 to rotate independently of hose 11 and front portion 46a. In this embodiment, holes 46b are
oriented at an angle effective to impart rotational momentum to rear portion 60 upon exit of high-pressure water, thus causing rear portion 60 to rotate while drilling. Holes 50 and 46b can be oriented such that front and rear portions (46a and 60 respectively) rotate in the same or opposite directions during drilling. Holes 18 and 46b are oriented in a reverse direction relative to forward direction A (Figs. 1 and 4) in order to help thrust the nozzle blaster along the bore. High pressure water is propelled through holes 18 and 46b, forming high pressure water jets 30 which impinge on the walls of the bore at such an angle as to help force the nozzle blaster forward by imparting drilling force to the nozzle blaster 24. Thus, the present invention has its greatest utility at shallow depths, where the length (and thereby the weight) of flexible hose in the vertical well is generally insufficient to supply adequate drilling force to the nozzle blaster 24 to propel it forward while drilling. As such, the present invention is preferably used at depths of at least, or not more than, 50, 100, 200, 300, 400, 500, 600, 700, 800, 900, or 1000 feet. Holes 18 and 46b also aid in keeping the bore clear behind nozzle blaster 24. Specifically, as hose assembly 10 is withdrawn from the bore, high pressure water or aqueous liquid forced through holes 18 cleans and reams the bore by clearing away any sand and dirt that has gathered behind nozzle blaster 24, as well as smoothing the wall of the freshly drilled bore. Preferably, hose assembly 10 is withdrawn from the bore by a coil tubing injector as known in the art, less preferably by some other known withdrawing means. Although the hereinabove described embodiments of the invention constitute the preferred embodiments, it should be understood that modifications can be made thereto without departing from the scope of the invention as set forth in the appended claims .
