Abstract
The invention relates to a two-phase multi-material online injection water-plugging profile regulating method and equipment. Liquid or solid-liquid mixed phase fluid is pumped by a self-sucking pump from a liquid storage tank, is conveyed to a high-pressure plunger pump and is injected into a high-pressure water-injecting pipeline after being pressurized; solid powders or small particles fall from a hopper under the action of the gravity and the vibrating force, and are sucked by negative pressure and mixed with jet flow; high-flow-velocity fluid carries the solid materials to enter a buffer tank; when the liquid level of the buffer tank is lower than the preset value, a liquid level controller sends out a signal to open an electromagnetic valve and supplement water to the buffer tank; when the liquid level reaches the highest position of the preset liquid level, the liquid level controller sends out a signal to close an electromagnetic valve and stopping water supplement to the buffer tank; and the powdery materials and the small particle materials are mixed with water and then enter the self-sucking pump respectively through a pipeline I with a static mixer or a pipeline II without the static mixer, and are injected into the high-pressure water-injecting pipeline after being pressurized by the high-pressure plunger pump. In the method, a solid-phase, liquid-phase or solid-liquid mixed phase water-plugging profile regulating agent can be injected into the high-pressure water-injecting pipeline in an online manner.
Description
Technical field
The present invention relates to a kind of online injection water plugging and profile controlling of two mutually more materials method and apparatus that directly in waterflood-transmission line, injects water plugging profile control agent or deep profile control agent.
Background technology
China all adopts the waterflooding extraction mode in most of oil fields.Rise rapidly at the development late stage composite water cut, the east China oil field has all got into high moisture, ultra-high water-containing mining phase, and composite water cut is up to more than 83%, and moisture output greater than 80% accounts for 74% of total output.Water plugging and profile controlling and deep profile controlling (transfer drive) are the important means of highly aqueous field control water stable yields (raising the output).
At present; Water plugging and profile controlling and deep profile controlling (transfer drive) construction; Basically be to adopt in having, water plugging profile control agent or deep profile controlling (transfer drive) agent to be made into design proportion, the method that injects into well by oil-water well pressure and traffic requirement with the water plugging and profile controlling pump more earlier with the dosing pond of electronic agitator.This construction operation exists: the preparation amount is big before 1. injecting operation, and 2. injection device, facility are huge, and it is big 3. to inject workload, and 4. energy consumption is high, and 5. metering is inaccurate in the injection process, and 6. injection rate is wayward, and the mechanism of 7. injecting such as can not adjust flexibly at problem.
The Chinese patent notification number is CN200810014371.X, and a kind of online injection profile control transfer drive method and apparatus is provided.Its method comprises in water injection well injects stifled agent, it is characterized in that said in water injection well, to inject stifled agent be online injection, the steps include: that (A) will block up agent and be stored in the fluid reservoir; (B) inject simultaneously by special-purpose injection device and injection water; (C) will block up agent through metering piston pump is incorporated in the online waterflood-transmission line; (D) stifled agent mixes with injection water in waterflood-transmission line, injects into well jointly, arrives oil reservoir; (E) inject total flow and well intake pressure through flow meter and pressure meter metering.
Summary of the invention
The purpose of this invention is to provide the online injection water plugging and profile controlling of a kind of two mutually more materials method and apparatus.That is: concentrate applying vibration blanking, negative pressure suction solid state powder or the mixing of small particles material jet, little volume surge tank to cushion the technology that the main line high pressure comes water, negative pressure suction liquid material, static mixing, solid phases such as compliance steer agent particle mixed liquor, activating agent liquid, polymer dry powder, volume expansion grain, liquid phase or solid-liquid are mixed the water plugging profile control agent or online being injected in the high pressure water injection pipeline of deep profile controlling (transfer drive) agent of phase.
The online injection water plugging and profile controlling of of the present invention two mutually more materials method is to comprise the water plugging profile control agent or online being injected in the high pressure water injection pipeline of deep profile controlling (transfer drive) agent of solid phases such as compliance steer agent particle mixed liquor, activating agent liquid, polymer dry powder, volume expansion grain, liquid phase or solid-liquid being mixed phase.Injection technology divides two branch roads to realize:
(1) mix the fluid class material of phase for liquid state or solid-liquid: liquid level is lower than the self-priming pump intake in fluid reservoir; Adopt negative pressure to suck liquid material; Directly from the fluid reservoir suction, be transported to high-pressure plunger pump through the flow meter metering by self priming pump, the high pressure water injection pipeline is injected in the pressurization back;
(2) for solid state powder or fine granularity class material: on the water filling main line, connect a high-pressure rubber pipe and attract water under high pressure; Water under high pressure produces the fluid of high flow rate through ejector; Vibrating bunker is installed above ejector, adopts the method for vibration blanking that solid material is evenly fallen in hopper under the effect of gravity and vibration force, suck and the jet method of mixing through negative pressure; Make the fluid of high flow rate carry solid material entering surge tank; Need keep in from the branch road water under high pressure that the drainage of water filling main line comes, can not directly flow to high-pressure plunger pump, because the water under high pressure flow of this throttling is difficult to mate with the input flow rate of high-pressure plunger pump; So designed a surge tank here, and on surge tank design and installation fluid level controller be connected the moisturizing tap line of using solenoid control.Guaranteed that through being provided with of this little volume surge tank high pressure comes the continous-stable of water to supply with and carry like this; The height of liquid level is controlled by fluid level controller in the surge tank, and when liquid level is lower than setting value, fluid level controller provides signal and opens electromagnetic valve; Come the moisturizing of water Zhi Luxiang surge tank by high pressure; Set the liquid level extreme higher position when liquid level arrives, fluid level controller provides the signal at stop electromagnetic valve, stops to the surge tank moisturizing.Powder material and little grainy material with get into self priming pumps through the pipeline two that the pipeline one of static mixer is housed or does not adorn static mixer respectively after water mixes, injection high pressure water injection pipeline after flow meter and high-pressure plunger pump pressurization afterwards.
Beneficial effect of the present invention: the online injection water plugging and profile controlling of the present invention's two mutually more materials method; Adopt this technology can avoid building facilities such as large-scale profile-controlling and plugging agent dosing pond, aerobic fermentation tank; Can water plugging profile control agent, deep transfer drive (profile control) agent be injected into the water filling main line through employing small-power injection device, thereby get into the purpose that water blockoff, profile control are played in the stratum.Adopt this technology can significantly improve water plugging and profile controlling, deep profile controlling (transfer drive) operating efficiency, cut down the consumption of energy, greatly alleviate productive labor intensity, and can realize adjustable, controlled injection mechanism.
