Abstract
The utility model discloses a sample injector of cyanide setting class blocking agent for rock core simulation blocking experiment, solving the problems that the existing sample injector has large volume, wastes materials, and is complex in operation and the like. A rear end thread of a shell is connected with a sealing cock; a plurality of cyanide setting size extruding holes are formed on the sealing cock; a sealing piston is arranged in an inner chamber of the shell; the inner chamber of the outer shell is divided into left and right compartments by the sealing piston; the right compartment serves as a cyanide setting size chamber; the left and right compartments are isolated from each other; and the water in the left compartment does not enter the cyanide setting size chamber at the right side. According to the sample injector provided by the utility model, a size storage tank is integrated into an extrusion injector; not only be pipeline and material saved, but also the cyanide setting size and the rock core are isolated only by the sealing cock, so that the loss of the size is reduced to the lowest extent. Furthermore as the independent size tank is omitted, the pressure loss on the pipeline is reduced, and the experiment procedure is simplified. In addition, the sample injector provided by the utility model has the advantage of operation easiness.
Description
Technical field
The utility model relates to a kind of rock core simulation shutoff experimental facilities, and concrete is the injector in the device squeeze note system.
Background technology
The cyanogen that Daqing oil field is commonly used in recent years coagulates the shutoff envelope technology of scurrying and is suitable for managing outer envelope of scurrying groove and scurries, and its outstanding characteristics are that technology is simple, and plug agent amount is few, and reaction speed is fast, and its intensity is high, and cost is low; Scurry in envelope and to have good advantages in the construction, but on the one hand, require definitely anhydrously during this stifled agent operation, use a large amount of organic solvents again, service condition is comparatively harsh; On the other hand, cyanogen is met behind the water reaction rapidly with fixed attention and is solidified, and with cement, steel pipe etc. good adhesive property is arranged, thereby causes constructional difficulties when water blockoff and envelope are scurried.So; Be necessary through course of reaction, Analysis on Mechanism and modification technology research; Make shutoff envelope scurry agent and have controlled, good, characteristic such as cementability is good, period of validity is long of bearing strength height, reaction speed and time with the stratum compatibility; And improve the safety that the shutoff envelope is scurried, and scurry the requirement of construction to satisfy thick oil pay shutoff and pipe covering, make that thick oil pay top remaining oil is effectively taped the latent power.
Coagulating the shutoff envelope at practical study cyanogen scurries in the technical performance process; When it being carried out rock core simulation shutoff experiment, for the rock core of length less than 6cm, because of its voids volume very little; The modification cyanogen that is used during squeeze note coagulates amount of slurry seldom; So whole squeeze note system and slurry can in the testing arrangement just become too huge, have wasted resource, and operation also seems complicated.
Summary of the invention
The purpose of the utility model provides the rock core simulation shutoff experiment that a kind of cyanogen coagulates type stifled agent and uses injector, this injector
Squeeze note system and slurry can are integrated, simplified experiment flow, saved pipeline and material, and reduced the loss of slurry.
For realizing the foregoing invention purpose, the technical scheme that the application adopts is: a kind of cyanogen coagulates the rock core simulation shutoff experiment of type stifled agent and uses injector, and its main body comprises squeeze note device head and housing department; Said housing department is cylindric; Comprise body and loam cake, tenon fourth of the twelve Earthly Branches bindiny mechanism is set between loam cake and the body, the sealing cock that is threaded of the tail end of housing department; In the inner chamber of housing department packed-piston is set; The packed-piston outer wall is with sealing ring, two compartments about the sealing piston is divided into the inner chamber of housing department, and its right-of-center in political views's compartment is that cyanogen coagulates slurry chamber; Said squeeze note device head is provided with some cyanogen in the sealing cock and coagulates the slurry extrusion cavities along the inlet opening that the central axis setting communicates with housing department.
The application's beneficial effect: the injector of the utility model; Original injector is carried out design again, slurry can has been incorporated in the squeeze note device, not only saved pipeline and material; And cyanogen coagulates slurry and rock core and only sealed cock and intercept, so that the loss of slurry is reduced to is minimum.Owing to reduced independently slurry tank, the pressure loss on the pipeline is reduced again, and experiment flow also obtains simplifying.Have, the application's injector also has the advantage of easy operating again.
Description of drawings
Fig. 1 is the structural representation of the application's injector.
The specific embodiment
Below in conjunction with accompanying drawing the application is further described:
By shown in Figure 1: a kind of cyanogen coagulates the rock core simulation shutoff experiment of type stifled agent and uses injector; Its main body comprises squeeze note device head and 1 housing department 2, and said housing department 2 is cylindric, comprises body and loam cake; Tenon fourth of the twelve Earthly Branches bindiny mechanism is set between loam cake and the body; The tail end of housing department 2 is threaded and seals cock 3, and packed-piston 4 is set in the inner chamber of housing department, and packed-piston 4 outer walls are with sealing ring 5; Two compartments about sealing piston 4 is divided into the inner chamber of housing department, its right-of-center in political views's compartment is that cyanogen coagulates slurry chamber 6; Said squeeze note device head 1 is provided with some cyanogen in the sealing cock 3 and coagulates slurry extrusion cavities 8 along the inlet opening 7 that the central axis setting communicates with housing department 2.
During use, open loam cake, coagulate in the slurry chamber 6 at cyanogen and add cyanogen to be tested and coagulate solution, build loam cake, this injector is contained in the live end of core holding unit, carry out the sample introduction operation then.During sample introduction; Water under high pressure enters into the left compartment of housing department through the inlet opening 7 of squeeze note device head; Promote packed-piston 4 and move right,, can guarantee that left and right compartment is isolated each other because of being with O-ring seal 5 outside the packed-piston 4; Do not coagulate in the slurry chamber 6 so the water of left compartment can not enter into the cyanogen on the right, because of meeting water curing reaction takes place yet with regard to not making cyanogen coagulate solution; The packed-piston 4 and then cyanogen in the slurry chamber 6 are coagulated solution exert pressure; Under above-mentioned pressure effect; Cyanogen coagulates solution and passes the extrusion cavities 8 above the sealing cock 3 and be injected in the rock core; Measure the breakthrough pressure and the plugging rate of rock core after sample introduction finishes, further study rock surface wetability and cyanogen and react the relation between the curing performance with fixed attention or carry out other performance studies.
