Description
Technical field:
The utility model relates to a kind ofly can produce the suitable stratum of injecting, and plays profile control, transfer drive, to the frothy gel generating means of energy energy.
Background technology:
Most of oil fields of present domestic land enter waterflood stage.Promptly from flatly or many mouthfuls of wells to the stratum water filling, recover the oil from another mouthful or many mouthfuls of wells, water is driven oil and is flowed to producing well, this process is the displacement of reservoir oil.The water that people imagine injection can be driven to producing well with the oil in the stratum as much as possible equably to flowing all around.And in fact because a variety of causes, injecting water often flows along a certain direction on the stratum, and other direction involve less than, cause waterflooding effect bad.If inject certain material in water injection well, this material can change the original water (flow) direction of injection water in the stratum, so just can improve waterflooding effect.This way is profile control, and the corresponding material that injects also is profile control agent sometimes profile control agent.Gel is a kind of maximum profile control agent of using.
Frothy gel is exactly an entrained gas in gel, forms the gel of similar sponge.
When oil field development enters stage middle and later periods, water filling, profile control, transfer drive, tertiary oil recovery etc. have become the means of requisite raising recovery ratio, because the aggravation of stratum energy deficit, cause the injection liquid measure of various measures in the stratum to increase gradually, be that the measure cost increases, final result is that cost for oil production increases, and reducing the measure cost has become a kind of inevitable; In order to reduce cost, the folk prescription that at first will reduce measure liquid injects cost.
The means of reduction measure liquid cost have three kinds:
1, reduces the dosing cost of measure liquid;
2, reduce the construction cost (injection cost) that injects liquid;
3, on the basis of original cost, increase the volume of measure liquid, promptly under equal cost situation, increase the swept volume that injects liquid;
First kind and second kind of scientific research personnel do a lot of work, and the third there be limited evidence currently of has the people to work in this respect, belongs to wait to develop or the ground zero stage.The frothy gel generating means is exactly to sneak into cheap air equably in the additional liquid of gel measure liquid or stratum, increases the volume that injects liquid, increases the swept volume of injection liquid under equal cost situation, thereby reaches the purpose that reduces cost.
The literature search situation:
Present literature survey is not found to utilize patent device to produce the report of frothy gel.The visible following document of other method:
[1] Zhao Renbao; Yue Xiangan; The spontaneous aerogel foam system of Hou Jirui single-fluid process deep profile controlling agent feasibility study, oilfield chemistry 2005.04
[2] Shangzhi state; Soviet Union state; Dong Yujie; The development of frothy gel selective water shutoff agent and application, 2000 01 phases of drilling technology
Prior art is mostly by chemical method inflation foaming.Promptly add a kind of or two kinds of medicaments in system, the medicament of Jia Ruing reacts angry gas under certain condition, thereby produces foam.The frothy gel cost that this method obtains is very high.Also have directly to feed gas in system, single frothy gel that produces like this is inhomogeneous.
Summary of the invention:
The purpose of this utility model is to provide a kind of frothy gel generating means, and simple in structure, construction cost is low, can be evenly dispersed in the more stable solution-air mixing phase of formation in the measure liquid to air, be frothy gel, the foam system that the frothy gel of generation forms is more even, and stationary phase is longer.And cost is lower.Help satisfying the demand of oil field heavy dose like this.
The utility model is achieved in that and comprises valve cover 1, valve 2, valve seat 3, outlet single current valve body 4, screen cloth 5, jackscrew 6, mixed phase chamber main body 7, diversion chamber's main body 8, wireway 13, pressure cap 16, gas ball-and-seat 17, air inlet pipe 18, feed liquor ball-and-seat 19, dosing mouth 20, inlet 21, porous plate 22, valve 2 is located on the valve seat 3, valve cover 1 is connected with valve seat 3, mixed phase chamber main body 7 is connected with diversion chamber main body 8, mixed phase chamber main body 7 is connected with outlet single current valve body 4, outlet single current valve body 4, porous plate 22, screen cloth 5, jackscrew 6 connects successively, diversion chamber's main body 8 is built-in with wireway 13, wireway 13 is communicated with air inlet pipe 18, feed liquor ball-and-seat 19 is communicated with inlet 21, and the sidepiece of inlet 21 is provided with dosing mouth 20.
Diversion chamber's main body 8 is fixing with wireway 13 by pressure cap 16.
Between wireway 13 and the air inlet pipe 18 gas ball-and-seat 17 is housed.
Advantage of the present utility model is: simple in structure, construction cost is low, and can be evenly dispersed in the more stable solution-air of formation in the measure liquid to air and mix phase, i.e. frothy gel, the foam system that the frothy gel of generation forms is more even, and stationary phase is longer.And cost is lower.Help satisfying the demand of oil field heavy dose like this.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
The specific embodiment
As shown in drawings, in outlet single current valve body 4, be equipped with valve cover 1, in a valve 2, bottom are arranged is that valve seat 3 usefulness jackscrews will be fixed on upper-part on the outlet single current valve body 4;
There is a mixed phase chamber main body 7 end of outlet single current valve body 4, and the steel plate of a porous is equipped with in inside, and promptly porous plate 22, and porous plate is for 22 times the screen cloth 5 that multipole screen cloth is formed by stacking, and is the jackscrew 6 of a fastening steel plate and screen cloth 5 below;
Mixed phase chamber main body is for 7 times diversion chamber's main body 8, and in order to spray, this also is this device main body part.Inside is streamlined, this is that the hydromechanical jet pump principle design of imitation processes, there is a high-pressure liquid jet wireway 13 at the center, the high pressure liquid that to come in is mixed in its venturi portion with coming gas, diversion chamber's main body 8 bottoms are one and have the centre bore plug 14 of (being used to wear the high-pressure injection pipe), liquid ball-and-seat and dosing mouth 20 are equipped with in the bottom of high-voltage tube, and an inlet 21 is equipped with in the side of diversion chamber's main body 8, and feed liquor ball-and-seat 19 is housed on the inlet 21.
Basic principle:
The operating principle of frothy gel generating means is to adopt hydromechanical jet pump operating principle to design.Highly pressurised liquid sprays into venturi and rapid depressurization by nozzle, make and form low-pressure area in the jet chamber, the gas that has certain pressure enters the jet chamber simultaneously, gas mixes at the venturi place with liquid gel, and together enter dispersing chamber, in entering the process of dispersing chamber at pressure, flow, gas dispersion become under the synergy of multiple screen cloth, porous plate etc. uniformly minute bubbles in gel or liquid, make it form more stable gas and gel (liquid) mixing mutually, and enter target zone jointly and bring into play its due effect.
