Description
Technical field
The present invention relates to oil and gas well drilling field, specifically a kind of multidirectional jet flow sand washing machine.
Background technology
Horizontal well construction operation, due to himself pit shaft feature, causes the grains of sand to be easily deposited on high angle hole section and net horizontal section, forms sand bridge and casting bed fast, for horizontal well sand washing operation brings larger difficulty.And adopt blank tubing or the oil pipe with conventional sand flushing tool mainly to carry out vertical sand washing downwards, if it enters net horizontal section, become the horizontal sand washing along pit shaft, effective flushing action cannot be carried out to borehole wall surrounding, and the grains of sand reduce climbing power at High angle section collision tube wall, easily along pit shaft deposition, again form casting bed, causing cannot by clean for pit shaft cleaning down, add the risk of pipe string sand card, cause easily occurring construction complex situations in construction in later period process.
Summary of the invention
The object of the invention is to: a kind of effective flushing, safe and reliable multidirectional jet flow sand washing machine are provided.
The technical solution adopted in the present invention 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, end installs nozzle; The outer peripheral face of described sand washing machine body tip has several circulation ports, this inside and outside of the through sand washing machine of this circulation port, the top of sand washing machine body is pointed in the oblique setting of this circulation port, direction, aperture.
Described circulation port decile be arranged on perpendicular to 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 °.
The outer peripheral face on described sand washing machine body top is provided with the rhone of helical-type line.
The beneficial effect formula that the present invention produces:
Multidirectional jet flow sand washing machine of the present invention can be used widely in horizontal well, has the advantages such as structure is simple, easy to process, with low cost, practical reliable, easy to operate; This multidirectional jet flow sand washing machine efficiently solves a difficult problem for horizontal well sand washing difficulty, and the flushing especially carrying out rapidly and efficiently to the pit shaft borehole wall, can also carry impurity simultaneously effectively; This multidirectional jet flow sand washing machine shortens construction period, improves construction timeliness and quality, avoids because sand-flushing does not thoroughly cause the risk precipitating card bury drills, ensure that construction safety; 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.
Accompanying drawing explanation
Fig. 1 is multidirectional jet flow sand washing machine structural representation of the present invention;
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.
Detailed description of the invention
The present invention is a kind of multidirectional jet flow sand washing machine, comprise connect successively top connection 5, sand washing machine body 3 and nozzle 1, 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 sand clean out pipe string; The end connection nozzle 1 of sand washing machine body 3.Characteristic point of the present invention is: on the outer peripheral face of sand washing machine body 3 end, have several circulation ports 2, the boring pipe of the through sand washing machine body 3 of this circulation port 2 and the external world, and the top of sand washing machine body 3 is pointed in the oblique setting of this circulation port 2, direction, aperture.This circulation port 2 decile is arranged on the same outer peripheral face perpendicular to sand washing machine body 3 axis, and the angle between its aperture and sand washing machine body 3 axis is 30 ° ~ 60 °.In addition, the outer peripheral face on sand washing machine body 3 top is provided with the guiding rhone 4 of helical-type line.
This detailed description of the invention be adopt welding tubing nipple to carry out processing, obtained multidirectional jet flow sand washing machine of the present invention, this multidirectional jet flow sand washing machine side face has three sections of step surfaces: tip portion be contact with sand clean out pipe the top connection 5, the mid portion that connect be the sand washing machine body 3 of rhone 4 is set, end section be the sand washing machine body 3 of circulation port 2 is set, least significant end grinding is opening conical points mouth shape (being nozzle 1).For reaching best sand washing, chip removal effect, being designed and sized to of these three sections of step surfaces: the external diameter of the external diameter < mid portion (arranging the sand washing machine body 3 of rhone 4) of the external diameter < end section (arranging the sand washing machine body 3 of circulation port 2) of tip portion (top connection 5).Concrete: the latus rectum of nozzle 1 is 15mm.Circulation port 2 is 4, decile is arranged on the same outer peripheral face perpendicular to sand washing machine body 3 axis, and meanwhile, the angle that its aperture is pointed between sand washing machine body 3 top and sand washing machine body 3 axis is 45 °, and this aperture is 10mm., rhone 4 axial along sand washing machine body 3 is the helicla flute that three roads be arranged in parallel, and its degree of depth and width are 6mm.
Duty of the present invention is: by this multidirectional jet flow sand washing machine by top connection 5 install this bottom sand clean out pipe string after, turn on pump circulating flushing sand washing well operations time, sand cleaning fluid is gone out at a high speed along through rushing nozzle 1 and circulation port 2, effectively can destroy husky bed, the grains of sand of the borehole wall are rushed, and by the rhone 4 of helical-type line, take sand grains out of pit shaft smoothly, so, improve sand washing effect, solve a horizontal well sand washing difficult problem.
