Abstract
The utility model relates to a tool specially used for drilling holes on an underground sleeve of a radial horizontal well with ultra-short radius, comprising a guideway slot, a drilling die, a cutter joint, cross joints, pin shafts, universal joints, upper joints and fixed upper joints. The results and the assembly relationship of the tool are as follows: the guideway slot is internally provided with a plurality of universal joints; the cross joints are arranged between the universal joints and the universal joints are fixedly connected with one another by the pin shafts; the upper end of the universal joint is connected with the upper joint; the external side of the upper joint is provided with the fixed upper joint; the internal end of the fixed upper joint is welded with the guideway slot; one side of the lower part of the guideway slot is provided with the drilling die and the cutter joint; and the cutter joint is connected with the universal joint by the cross joint. The tool has reasonable design and novel structure, is convenient for use, has reliable and practical operation, can save construction period and cost for milling, hole-expanding and well completion of the sleeve, and is suitable for popularization and application.
Description
Technical field:
The utility model relates to a kind of drilling well downhole tool that is used for the super short radius horizontal well technology.
Background technology:
The super short radius horizontal well technology is a new technology that develops rapidly recent years, and getting out the production runner that reaches 30～50 meters from former well short radius in the reservoir can effectively increase drainage area, is mainly used in old well production potential tapping transformation and new well completion.But need carry out when implementing this technology sleeve pipe forge mill, reaming, completion, cause the construction cost height, make the exploitation comprehensive economy be affected.
The utility model content:
The purpose of this utility model be to provide a kind of adopt the pipe box internal drilling carry out radial aperture, can save sleeve pipe forge mill, the super short radius horizontal well down-hole casing boring special tool of reaming, completion construction period and cost
The utility model is to realize like this.This kind special tool by guide-track groove, drill jig, cutter adapter, cruciform joint, pivot pin, universal joint, top connection and fixedly top connection form, its result, assembled relation are as follows: be provided with a plurality of universal joints in the guide-track groove, be provided with cruciform joint between each universal joint and be connected and fixed with bearing pin, the universal joint upper end is connected with top connection, the top connection outside is provided with fixedly top connection, and fixedly top connection is inner welds mutually with guide-track groove; Guide-track groove bottom one side is provided with drill jig and cutter adapter, and cutter adapter is connected with universal joint by cruciform joint.During the horizontal well casing pipe hole opening operation, drive the side steering formed by top connection, cruciform joint, pivot pin and a plurality of universal joint, cutter adapter in guide-track groove by the hydraulic-driven screw rod, smooth rotation, advance, drilling fluid enters in the guide-track groove by the top connection hydrophthalmia, realize lubricated, cooling and chip removal, the cutter that the cutter adapter lower end connects is followed rotation, finishes casing pipe hole opening.
The utility model is reasonable in design, and novel structure is easy to use, the reliable operation practicality, utilize it can save sleeve pipe forge mill, the construction period and the cost of reaming, completion, be suitable for and apply.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment:
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model is by guide-track groove 1, drill jig 2, cutter adapter 3, cruciform joint 4, pivot pin 5, universal joint 6, top connection 7, fixedly top connection 8 is formed.Wherein, guide-track groove is a cylinder, and inside has a level and smooth arc track, and arc track is realized 90 ° of break-ins in the long guide-track groove 1 of 300mm.Drill jig 2 profiles are a cylinder, and interior forward end is a cylindrical hole, and the rear end is a taper hole, are welded on the guide-track groove 1 with brazing, and its effect is spacing, directed, guarantee that cutter is accurate when creeping into, steady.Cutter adapter 3 point diameters and drill jig 2 outlet diameters coupling, the rear end diameter is identical with universal joint 6, and extends upward the pivot ear of two opposite positions, respectively establishes a pin hole with pivot ear desired location and pivot pin 5 is passed with cruciform joint 4 be connected with universal joint 6; The middle cone transition, tapering and drill jig 2 taperings coupling play position-limiting action, and inside is screwed hole, links drilling tool.Cruciform joint 4 is a tetragonal body, and tetragonal body two-phase opposite ends is respectively equipped with pin hole, and pivot pin 5 passes pin hole, and cruciform joint 4 is linked between universal joint 6, cutter adapter 3, top connection 7 two-phase staggered joint.Pivot pin 5 passes pin hole and connects cruciform joint 4.Universal joint 6 is a cylinder, the cylinder outer rim extends upward the pivot ear of two opposite positions, and respectively establish a pin hole in a desired location, this pivot ear is connected with cruciform joint 4, each pivot ear both sides forms a circular arc camber and links to each other with sleeve, cruciform joint is connected between two universal joints, 6 interlaced pivot ears, makes two joints can rotate other angles smoothly.Top connection 7 rear end profiles are a cylinder, and inside is screwed hole, connect hollow stem, and have a hydrophthalmia; Point diameter is identical with universal joint 6 diameters, and extends the pivot ear of two opposite positions, respectively establishes a pin hole with pivot ear desired location and pivot pin 5 is passed with cruciform joint 4, universal joint 6 be connected; Middle cone is excessive.Fixedly top connection 8 is a cylinder, is welded on the guide-track groove 1 with brazing, and inside is 2
