Abstract
The utility model provides a multi-directional jet flow sand washing device which comprises a sand washing device body and a nozzle, wherein a pipe cluster is connected with the top end of the sand washing device body; the nozzle is arranged at the rear end of the sand washing device body; a plurality of circulation holes are arranged on the periphery plane of the rear end of the sand washout device body; the circulation holes are communicated inside and outside the sand washing device body; and the circulation holes are arranged in inclination and the aperture direction faces to the top end of the sand washout device body. The sand washing device can be widely used in a horizontal well and has the advantages of being simple in structure, convenient to machine, low in cost, practical and reliable, convenient to operate and the like; the difficult problem that the sand washing in the horizontal well is difficult is effectively solved; particularly well shafts and well walls can be washed rapidly and effectively; and meanwhile, the impurities can be carried over effectively; the construction period is shortened; the time efficiency and the quality in construction are improved; the risk that drills are buried by the sediment as the sand is not washed out thoroughly is avoided; the construction security is ensured; the application range is wide; and therefore, the sand washing device is easy to be popularized and used in large scale and has very wide application prospect.
Description
Technical field
The utility model relates to the oil and gas well drilling field, specifically a kind of multidirectional jet flow sand washing machine.
Background technology
The horizontal well construction operation owing to himself pit shaft characteristic, causes the grains of sand easily to be deposited on high angle hole section and net horizontal section, forms fast sand bridge and casting bed, for the horizontal well sand washing operation brings larger difficulty.And adopt blank tubing or mainly be to carry out vertical sand washing downwards with the oil pipe of conventional sand flushing tool, if entering net horizontal section, it has then become horizontal sand washing along pit shaft, can't be to carrying out effective flushing action around the borehole wall, and the grains of sand reduce climbing power at large gradient section collision tube wall, easily along the pit shaft deposition, again form casting bed, causing can't be clean with the pit shaft cleaning down, increase the risk of pipe string sand card, caused in the construction in later period process, being prone to the construction complex situations.
Summary of the invention
The purpose of this utility model is: a kind of effective flushing, safe and reliable multidirectional jet flow sand washing machine are provided.
The technical scheme that the utility model adopts is:
A kind of multidirectional jet flow sand washing machine comprises top connection, sand washing machine body and nozzle, and the top of sand washing machine body connects top connection, the terminal nozzle of installing; Have several circulation ports on the outer peripheral face of described sand washing machine body tip, this circulation port connects this inside and outside of sand washing machine, and the oblique setting of this circulation port, aperture direction are pointed to the top of sand washing machine body.
Described circulation port five equilibrium be arranged on perpendicular to the sand washing machine body shaft to outer peripheral face on.
The aperture of described circulation port and sand washing machine body shaft between angle be 30 °～60 °.
Be provided with the rhone of helical-type line on the outer peripheral face on described sand washing machine body top.
The beneficial effect formula that the utility model produces:
Multidirectional jet flow sand washing machine of the present utility model can be used widely in horizontal well, has the advantages such as simple in structure, easy to process, with low cost, practical reliable, easy to operate; This multidirectional jet flow sand washing machine efficiently solves the difficult problem of horizontal well sand washing difficulty, especially can carry out rapidly and efficiently flushing to the pit shaft borehole wall, can also effectively carry impurity simultaneously; This multidirectional jet flow sand washing machine has shortened construction period, has improved construction timeliness and quality, has avoided having guaranteed construction safety because sand-flushing does not thoroughly cause the risk of precipitation card bury drills; This multidirectional jet flow sand washing machine has wide range of applications, and is easy to large-scale promotion and use, and application prospect is quite wide.
Description of drawings
Fig. 1 is multidirectional jet flow sand washing machine structural representation of the present utility model;
Fig. 2 is the positive view of Fig. 1;
Number in the figure represents: 1-nozzle, 2-circulation port, 3-sand washing machine body, 4-rhone, 5-top connection.
The specific embodiment
The utility model is a kind of multidirectional jet flow sand washing machine, comprise the top connection 5, sand washing machine body 3 and the nozzle 1 that connect successively, concrete: the top of sand washing machine body 3 connects top connection 5, and the external diameter of top connection 5 is less than the circumferential external diameter of sand washing machine body 3, for connecting the sand clean out pipe string; The terminal connection nozzle 1 of sand washing machine body 3.Characteristic point of the present utility model is: the outer peripheral face at sand washing machine body 3 ends has several circulation ports 2, this circulation port 2 connects boring pipe and the external world of sand washing machine body 3, and these circulation port 2 oblique settings, aperture direction are pointed to the top of sand washing machine body 3.These circulation port 2 five equilibriums are arranged on perpendicular on the axial same outer peripheral face of sand washing machine body 3, and its aperture and sand washing machine body 3 angle between axially is 30 °～60 °.In addition, the outer peripheral face on sand washing machine body 3 tops is provided with the guiding rhone 4 of helical-type line.
This specific embodiment is to adopt the welding tubing nipple to process, make multidirectional jet flow sand washing machine of the present utility model, and this multidirectional jet flow sand washing machine side face has three sections step surfaces: head portion is that the top connection 5, the mid portion that connect with the sand clean out pipe series winding are that sand washing machine body 3, the end portion that rhone 4 is set is that sand washing machine body 3, the least significant end grinding that circulation port 2 is set is opening conical points mouth shape (being nozzle 1).For reaching best sand washing, chip removal effect, being designed and sized to of this three sections step surfaces: the external diameter of the external diameter＜mid portion (the sand washing machine body 3 of rhone 4 is set) of the external diameter＜end portion of head portion (top connection 5) (the sand washing machine body 3 of circulation port 2 is set).Concrete: the latus rectum of nozzle 1 is 15mm.Circulation port 2 is that 4, five equilibrium are arranged on perpendicular on the axial same outer peripheral face of sand washing machine body 3, and simultaneously, sand washing machine body 3 tops are pointed in its aperture, the angle between axial with sand washing machine body 3 is 45 °, and this aperture is 10mm.Along sand washing machine body 3 axially, rhone 4 is the helicla flute that three roads be arranged in parallel, its degree of depth and width are 6mm.
Duty of the present utility model is: should multidirectional jet flow sand washing machine installing by top connection 5 should be behind sand clean out pipe string bottom, during turn on pump circulating flushing sand washing well operations, sand cleaning fluid is along going out at a high speed through rushing nozzle 1 and circulation port 2, can effectively destroy husky bed, the grains of sand of the borehole wall are rushed, and the rhone 4 by helical-type line, take sand grains out of pit shaft smoothly, so, sand washing effect, a solution horizontal well sand washing difficult problem have been improved.
