Tens meters per minute of down tube speed (maximum down tube speed：60 ms/min) larger impulse force can be produced, make rotary nozzle and company
Continuous oil pipe tube wall frictional resistance greatly reduces, and can easily pass through deep fat or heavy oil tested layer 80, especially in the deeper and deeper feelings of oil reservoir
Under condition, coiled tubing is not obstructed with entering under rotary nozzle with the increase of depth, and down tube becomes very easy.
Rotary nozzle ultrasonic cavitation effect can in moment by hydrolytic dissociation into ionic condition, the activating agent in thinner
Under high pressure hypernormal, due to the space at heavy oil tested layer 80 in pit shaft it is little, high-pressure spray pressure make in sleeve pipe confined space water/
Agent/fry dried food ingredients life quickly mixes and rubs, and the bound state between viscous crude self-molecules present is broken rapidly.This motion ratio normality injecting drop
Viscous efficiency improves 300%, and viscous crude physical state is in Aphron shape, and mobility is fabulous, reducing crude oil viscosity particle fine and even, and this is
What other technologies cannot be realized.
Further, on the ground temperature control is carried out to viscosity reduction medicament, for example, is incubated, make the viscosity reduction medicament
Uniformly mixed with viscous crude with 35 degree of -55 degree in down-hole, electrical heating cost more viscous than general chemistry injecting is lower.
Further, the rotary nozzle has two front nozzles and six rear nozzles, and two front nozzle rotational shears are opened
Road, six rear nozzles penetrate power after producing, using high pressure rotary sealing technology, strong magnetic speed limit technology, jewel nozzles antiscour technology,
Under elevated pressure conditions whole system can reach and fully seal, and the rotating speed of the rotary nozzle is 1500-3000r/min, so, rotation
Turn the huge pressure that shower nozzle overcomes heavy oil tested layer generation, Stirring, the effect of high pressure local cavitation can be played, have it is very strong from
Drilling ability；There is (perforated interval well-flushing) rotary nozzle direct projection to clean borehole function, and it is largely effective that depth cleaning improves permeability.
This rotary nozzle is high speed rotary nozzle, can be buied from the market.
The present invention can be according to the viscosity of viscous crude and constituent analysis, using the dynamic (dynamical) computing formula of water conservancy, before operation
Crude oil is analyzed, the job parameters such as coiled tubing size, depth, mouth footpath, pressure value, displacement value, frictional resistance are calculated, for
The viscous crude characteristic of different blocks selects optimal job parameter.Outside being suitable for heavy oil wells, for the low yield for needing Chemical Treatments
Well/accident well is equally applicable.
