Description
Technical field
The present invention relates to oil-gas mining field, more particularly, to a kind of based on the side for improving water under high pressure rotating jet speed
Method.
Background technology
Oil gas is the gas from oil well out with oil, and main component is methane, ethane etc..As fuel and chemical industry
Raw material.Oil-gas generation has following condition, first, to see organic matter quantity in source bed number, commonly referred to as " organic matter is rich
Degree ".The organic carbon content wherein remained is mainly determined, to determine an area whether there is source bed, how many source bed, and it
Be divided into by certain standard, medium and poor source bed, carry out evaluation of classification.Second, to see organic in source bed
The quality of matter quality, commonly referred to as " organic matter type ".According to biological source, the kerogen of Oil source bed is divided into three major types.
The first kind is sapropelic organic matters, and biological source is mainly the plankton in water, is I type kerogens, and category is top-quality
Organic matter.Second class is rotten plant type organic matter, and biological source is mainly higher plant, is type III kerogen, belongs to second-rate
Organic matter.3rd class is mixed type organic matter therebetween, is II type kerogens, is the preferable organic matter of quality.It is real
Room is tested by the analysis result to sample, a regional organic matter type is determined by certain standard, to the quality of organic matter
Make evaluation.3rd, it is gentle to see whether organic matter has generated oil, commonly referred to as " maturity of organic matter ", when possessing
The organic matter of certain amount and quality is changed into after oil under certain conditions.In other words, if not possessing generation oil
" duration and degree of heating ", organic matter at most, be desirably also without what real value.So the maturity of research organic matter is critically important
A ring.The information that analyze data is provided, the temperature course that organic matter undergoes in underground can be reflected indirectly.According to these numbers
According to, maturity be divided into immature, oil generation peak, moisture, dry gas (dry gas refers to that its origin cause of formation is relevant with oil, and containing ethane with
On heavy hydrocarbon it is seldom, the flammable natural gas of methane content more than 95%.It is close with this as the composition of biogas and coal-type gas, but
The origin cause of formation is different, shoulds be regarded as a different matter.) etc. four-stage.What stage of ripeness evaluation organic matter is in, and people can be told on some ground
Area is advantageous for oil prospecting or gas finding.4th, to see that the oil of generation or gas are from that source bed, commonly referred to as " oil sources
Contrast ".I.e. after oil gas is found, oil gas and oil source rock are carried out pair with " fingerprint compound " (or biomarker)
Than, explore the affiliation between oil source rock and oil gas, research institute's generation it is oily it is gentle be from that source bed.It is not difficult to think
As, there is provided the source bed of oil sources is more, and oil sources is abundanter, to forming oil gas field just advantageously.In hydraulic fracturing process,
Traditional fracturing technology is uneven there is pressure break, and during pressure break the problem of easy card sand.
The content of the invention
It is an object of the invention to overcome above-mentioned existing fracturing technology uneven there is pressure break, and easily block during pressure break
The problem of sand, a kind of method based on raising water under high pressure rotating jet speed is devised, the technique can improve fracturing effect, make
Pressure break is uniform, while be not in the phenomenon of card sand, and the efficiency of pressure break improves, solve existing fracturing technology there is
Pressure break is uneven, and during pressure break the problem of easy card sand.
The purpose of the present invention is achieved through the following technical solutions：Based on the method for improving water under high pressure rotating jet speed, bag
Water under high pressure rotating jet deblocking tool is included, the water under high pressure rotating jet deblocking tool is mainly by down-hole filter, centralizer, rotation
Transcoder controller and self-vibration cavitation injector form, and pass through cementing truck to pending target zone, treatment fluid under kit oil pipe
Suppress and enter rotating generator after check valve, filter, produce multiply radial high-pressure water jet, be distributed four along surrounding on shower nozzle
Individual accordion type spray nozzle, two of which tilt power nozzle spray lateral jet and produce turning moment, driving shower nozzle rotation, two footpaths
Radial direction high frequency self-resonating cavitating jet is produced to nozzle, directly impacts tube wall and stratum, instrument moves up and down when underground is in rotation,
Rotary speed is controlled by Rotation Controllers, and each rotation has four waterpower pulses, while produces low frequency rotating hydrodynamic wave (H wave), high frequency vibrating
Three kinds of shock wave, cavitation noise ultrasonic wave physical action comprehensive function stratum are swung, reach the complete processing to whole perforated interval；
When low frequency rotating hydrodynamic wave (H wave) is jet ejectors rotation, rotation hydraulic disturbance ripple, rotary speed 100 are produced in pit shaft
~400r/min, low frequency rotating hydrodynamic wave (H wave) act on stratum, make to be deposited on mechanical admixture in formation pore and tamper is gradual
Loose or dislocation, scattered washed away in a liquid by water jet are taken out of, are reached dredging duct, are released the purpose blocked, meanwhile, formation rock
Stone produces tired microcrack net under the repeated action of low frequency rotating hydrodynamic wave (H wave), and gos deep into hydrodynamic wave (H wave), and crack constantly expands
And extension；
Self-oscillation flow jet flow has strong pressure oscillation and erosion rock effect, and jet vibration frequency is thousands of to up to ten thousand conspicuous
Hereby, pressure fluctuation amplitude is up to 24%~37%, and under the conditions of same pump pressure, erosion rock effect is 2~4 times of conventional jet, is sprayed
Emitter rotates a circle in underground produces 4 waterpower pulses, and each waterpower pulse is again in itself self-oscillation flow jet flow, and self-oscillation is penetrated
Stream impacts de-plugging directly near wellbore zone deep penetration, while makes formation rock impact grinding, new microcrack is produced, so as to carry
High in-place permeability；
Cavitation noise ultrasonic wave is that generation high frequency, intense radiation, deep penetration cavitation are made an uproar while injector produces higher-order of oscillation jet
Sound, frequency are up to 10kHz, and high-frequency ultrasonic helps to dredge fluid swivels, increases formation pressure gradient, changes crude oil molecule knot
Structure, viscosity of crude is reduced, reduce the surface tension on rock and oil-water interfaces, so as to improve crude oil fluidity, improved crude oil and adopt
Go out degree.
In summary, the beneficial effects of the invention are as follows：The technique can improve fracturing effect so that pressure break is uniform, simultaneously
Be not in the phenomenon of card sand, and the efficiency of pressure break improves, it is uneven there is pressure break to solve existing fracturing technology, and
During pressure break the problem of easy card sand.
