Abstract
An artificial sand-packed model tube for oil field experiments mainly solves the problem that an existing artificial sand-packed model tube can not be used for effectively simulating the effective distribution of a pressure field in the displacement process. The artificial sand-packed model tube for field experiments is characterized in that an inner hole of a tube body (1) is square, pressure measuring holes (3) are formed in the side wall of the tube body (1), filters are arranged in the pressure measuring holes (3), tube end caps (2) are connected to the two ends of the tube body (1) in a closed mode, grooves (4) are formed in the tube end caps (2), and filters are arranged in the grooves (4). The artificial sand-packed model tube for oil field experiments has the advantage of being capable of better simulating the distribution of the pressure field on the same displacement section.
Description
Technical field
The present invention relates to the model that oil recovery rate physical simulation experiment is used, especially the artificial sandpack column pipe of oil field experiment.
Background technology
In oil recovery rate physical simulation experiment, conventional artificial sandpack column pipe.And existing artificial sandpack column bore is circle, although the displacement of chemical agent in oil reservoir and transport conditions can be simulated, but effectively can not simulate effective distribution of pressure field in displacement process, especially the distribution of pressure field on same cross section, and the distribution situation of chemical agent on same cross section.
Summary of the invention
The problem of effective distribution of pressure field in displacement process effectively can not be simulated in order to solve existing artificial sandpack column pipe.The invention provides the artificial sandpack column pipe of a kind of oil field experiment.The experiment of this oil field has had better the feature of the distribution of pressure field on the same displacement cross section of simulation with artificial sandpack column pipe.
Technical scheme of the present invention is: the experiment of this oil field comprises body and pipe end-cap with artificial sandpack column pipe.Body endoporus is square, tube wall has pressure tap, has strainer in pressure tap, and pipe end-cap is airtight is connected to body two ends, and fluted in pipe end-cap, groove is built-in with strainer.
Pipe end cover bolt in such scheme is airtight is connected to body two ends; Body both ends of the surface have ring packing boss, have counterbore inside seal boss, and pipe end-cap inner face has the sealed groove matched with seal boss, and sealed groove is built-in with sealing ring, and pipe end-cap inner face has boss, boss upper groove; Strainer is made up of iron end alloy; Pressure tap internal diameter is 1 millimeter; Pressure tap design is on same cross section; Pressure tap can also use as thief hole; Tube length is 1000 millimeters, and internal diameter is 30 millimeters × 30 millimeters.
The present invention has following beneficial effect: this oil field is tested with artificial sandpack column pipe owing to adopting body endoporus to be square, tube wall there is pressure tap, strainer is had in pressure tap, pipe end-cap is airtight is connected to body two ends, have sealed groove in pipe end-cap, sealed groove is built-in with the structure of strainer.Utilize the body of square inner bore, the distribution of pressure field on the better same displacement cross section of simulation.The experiment of this oil field is square with artificial sandpack column bore, and breaching conventional artificial's sandpack column bore is circular pattern; The experiment of this oil field is used iron end alloy instead by artificial sandpack column pipe boss upper groove built-in filter and is made, and it is convenient to rinse, and not easily blocks; The experiment of this oil field experimentally needs with artificial sandpack column pipe pressure tap, can also use as thief hole; The experiment of this oil field with the design of artificial sandpack column pipe pressure tap on same cross section, can be better the distribution of pressure field on the same displacement cross section of simulation, provide new technological means for carrying out laboratory physical simulation experiment.The experiment of this oil field has had better the feature of the distribution of pressure field on the same displacement cross section of simulation with artificial sandpack column pipe thus.

detailed description of the invention:
Below in conjunction with accompanying drawing, the invention will be further described:
As shown in Figure 1, the experiment of this oil field comprises body 1 and pipe end-cap 2 with artificial sandpack column pipe.Metal tube 1 endoporus and profile are square, and body 1 length is 1000 millimeters, and internal diameter is 30 millimeters × 30 millimeters, body 1 has 3 pressure taps 3 on the upper side wall of same cross section, have strainer in pressure tap 3, strainer is made up of iron end alloy, and pressure tap 3 internal diameter is 1 millimeter.Pressure tap 3 can also use as thief hole, and body 1 both ends of the surface have ring packing boss 5, have counterbore inside seal boss 5.
Pipe end-cap 2 inner face has the sealed groove matched with seal boss 5, and sealed groove is built-in with sealing ring, and pipe end-cap 2 inner face has boss, boss upper groove 4, and groove 4 is built-in with strainer, and strainer is made up of iron end alloy.
The seal boss 5 of body 1 is placed in the sealed groove of pipe end-cap 2, is then connected to body 1 two ends with 8 bolts by airtight for pipe end-cap 2.
The experiment of this oil field improves traditional artificial sandpack column pipe with artificial sandpack column pipe, internal diameter is become square from circle, same section devises three pressure taps arranged side by side, effectively can simulate chemical agent migration and redistribution situation in the earth formation like this, solution must not simulate effective distribution of pressure field in displacement process effectively, especially the distribution of pressure field on same cross section, and the distribution situation of chemical agent on same cross section.
This oil field experiment artificial sandpack column pipe room physical contradictions checking by experiment, can meet the Pressure behaviour change of lab simulation oilbearing stratum, the dynamic migration process of chemical agent, have good on-the-spot guidance meaning.
