Background technique
With being gradually increased for directional well, the continuous development of horizontal well technology and reservoir reconstruction scale, especially horizontal well
" thousand side's sand, all places liquid " are segmented the sizable application of more clusters " volume fracturing ", and sand production problem is got worse, to a certain extent shadow
The effective smooth development played with later period measure for having rung production capacity, need to carry out sand-flushing operation in time.
Currently, conventional pen tip is still main sand flushing tool used by each elephant, but there is the following in it: one
It is that sand washing is in the form of a single, the effective flush clean borehole wall of eddy flow, the guarantee good passability of pit shaft cannot be passed through；Second is that big oblique
In degree, horizontal segment sand washing operation, according to direct circulation sand washing, by well track and laminar flow effects, wellbore bottom sand setting is difficult
It is rushed with thorough, and rushed sand grains secondary precipitation can occur, easily causes sand plug card；According to inverse circular sand washing adapter, sand cleaning fluid impact
Power is substantially reduced, and frequently can lead to sand washing without drilling depth when encountering densification, agglutination sand face；Third is that in mesolow oil reservoir, especially
In the low pressure oil well in segmentation transformation, more shower holes when sand washing, sand cleaning fluid leakage is serious, while influencing construction efficiency, to oil
Layer will also result in a degree of pollution.
It has carried out improving perfect and transformation innovation in view of the above problems, some oil fields have been based on conventional pen tip, but still has had

Specific embodiment
Embodiment 1:
It present embodiments provides a kind of reacting cycle big orifice cyclone sand washing device, including central tube 6 and is set to 6 lower end of central tube
Pen tip 1, the central tube 6 is externally provided with bushing pipe 2, and 2 middle part of bushing pipe connect to form circular passage 7 with central tube 6, the lining
2 top of pipe is circumferentially uniformly provided with multiple bar shaped inlet opening 2-2, and multiple bar shaped inlet opening 2-2 are communicated with circular passage 7；
The bushing pipe 2 is equipped with first boss and second boss, the first boss be set to multiple bar shaped inlet opening 2-2 it is outer and
The upper end of first boss is lower than the input end of multiple bar shaped inlet opening 2-2, and the leather cup 5 that shuts off, institute are installed with outside the first boss
The lower part that second boss is set to bushing pipe 2 is stated, the second boss is circumferentially uniformly provided with multiple whirl hole 2-1.
The present embodiment use is shut off leather cup 5 and whirl hole 2-1, and high speed rotation jet stream is formed in inverse circular sand washing adapter with this,
Sand setting, while the flush clean borehole wall can be effectively broken up and be spun up, ensure that good passability.Shut off and leather cup 5 while avoiding
Stratum below leather cup or perforated interval directly contact power sand cleaning fluid, effectively reduce the formation leakage amount of mesolow oil well, improve
Sand washing efficiency reduces the injury to bottom.
Due to not designing any structure in central tube 6, ensure that and return channel on larger, effectively prevent bulk sand grains or
The falling-well matters part such as rubber blocks sand flushing tool.
Embodiment 2:
On the basis of embodiment 1, a kind of reacting cycle big orifice cyclone sand washing device is present embodiments provided, further includes leather cup
