Abstract
The utility model relates to an oil well low frequency wave resonance oil production device, comprising a variable frequency and pressure instrument, a control instrument, a downhole sensor and a downhole sound wave vibration source. During the construction the downhole tool is fed into the borehole by the cable and is also provided with power, thus the downhole tool can generate vibration wave which shocks the formation to vibrate, through the adjustment of the surface instrument, the vibration frequency of the downhole vibration source can reach the resonance frequency of the reservoir, the larger vibration wave can be formed using less power under the ground through the resonance. When the utility model is combined with the chemical viscosity reducing agent together, the objective of oil increasing and viscosity reducing can be obtained, the combination is the effective method of heavy oil mining mode converting and low permeability ground treatment.
Description
The utility model relates to a kind of oil well low frequency wave resonance extracting device of oil, belongs to oil field downhole oil extraction device class.
In thickened oil recovery, generally all use exploitation via steam injection at present, inject a large amount of high-temperature steams, allow oil reservoir intensification reducing crude oil viscosity and make crude oil change fluid ability, finally realize crude oil production on exploitation forward direction stratum.Why viscous crude needs exploitation via steam injection, mainly be because viscosity of thickened oil is too big, be difficult in the formation temperature current downflow, must to reduce the purpose that viscosity just can reach viscosity reduction, present widely used temperature-raising method, also have methods such as chemical viscosity reduction, underground cracking in addition, because the chemical viscosity reduction cost is low, do not injure oil well casing, and chemical liquids generally is difficult to fully mix with underground crude oil and the effect that do not reach, have only in 10 meters of the wellbore radius a large amount of oil extraction difficulties that surpass from 10 meters in pit shaft with the exploitation via steam injection influence area.Therefore, the stirring problem that how to solve the chemical viscosity reduction viscous crude has become current key problem in technology, a kind of oil well low frequency wave resonance extracting device of oil can play the chemical viscosity reduction agent fully to be mixed with crude oil underground, reach viscosity reduction crude oil extraction purpose, simultaneously also can remove oil layer pollution, also can be at the underground fine fisssure incremental oil production that causes.
The purpose of this utility model is a kind of oil well low frequency wave resonance extracting device of oil that provides in order to overcome above-mentioned shortcoming.
The utility model is to realize like this.
It mainly utilizes a ground frequency modulation device, control device, sensor (also can be placed on underground) and cable and places the low frequency wave generator and the down-hole acoustic receiver makes it form a system in oil well, utilize each partly function, can obtain the effect of vibration stratum to stratum emission vibration wave and play unexpected technique effect; When using this device at first the well site sonic generator instrument is connect good after, the down-hole instrument is lowered into the oil reservoir position in shaft bottom by cable, adjust frequency of supply and voltage by ground instrument, pass to and make after underground vibration source produce vibration, then by whether reaching resonance in down-hole and the Ground Control instrument detecting well, all the time make the frequency shift of underground low-frequency sonic generator during work, progressively adjust to till the resonance frequency on frequency and stratum, allow instrument long-term work under resonance frequency, the final purpose that realizes the vibration stratum.Therewith, in vibration, the chemical viscosity reduction agent is injected in the oil reservoir with pump, chemical agent just can mix with the crude oil of oil reservoir under the vibration state of stratum well, reach the purpose of viscosity reduction, after having injected, the chemical viscosity reduction agent continues the vibration certain hour, thereafter take out instrument in the well, can exploit the crude oil of viscosity reduction.
The utility model advantage is to use low frequency wave resonance device fiting chemical viscosity reduction that reducing thick oil viscosity is had more than steam-assisted recovery and simple chemical viscosity reduction heavy crude producing in the technology of showing and descends the big characteristics of crude oil area drivingly, it is present viscous crude conversion mining type, the optimal technology of low permeability pay floor treatment, in construction, can not injure oil well casing in addition, also can remove simultaneously the pollution of oil reservoir, can also in the stratum, make microcrack and reach the incremental oil production purpose.
The utility model is provided by following examples.
Narrated below in conjunction with accompanying drawing.
Accompanying drawing the utility model structural representation
Among the figure, 1 variable-frequency variable-voltage controller, 2 Ground Control instrument, 3 ground transaucers, 4 cables, 5 down-hole sonic generators, 6 downhole sensors, 7 oil reservoirs, 8 pulleys, 9 thinners inlet.
