Abstract
The utility model relates to a rock core test meter for simulating the process that a rock is polluted by working liquid under a well. The utility model is characterized in that a pressure barrel with test liquid is installed on the upper end of an upper press cap for fixing, a top cap is installed on the upper end of the pressure barrel with test liquid, and the top cap is provided with a pressure introduction port. A lower press cap for fixing is provided with a filtrate pipe, and a heating sleeve is installed on the outer ring of a steel sleeve and the pressure barrel with test liquid. Test working liquid infiltrates in a test rock core through pressing and heating in the pressure barrel with test liquid, and the utility model can measure the polluted situation of the test rock core.
Description
The utility model relates to a kind of core test unit, particularly a kind of core test instrument of artificial ground contamination of working fluid rock.
In the petroleum drilling and mining production run, many operation process, as: drilling well, pressure break, acidifying, well workover, perforation etc., its working fluid all can pollute infringement to oil reservoir.But how on earth pollute, the degree of pollution damage how, is positioned at oil reservoir under the situation of underground thousands of meters depths, is difficult to observe practically.Therefore; must carry out simulation test on ground; to understand working fluid is how to invade pollution to oil reservoir in the down-hole; the reservoir physical property of being invaded after the pollution has anything to change; so that develop corresponding work liquid; reduce pollution as far as possible, alleviate infringement, reach the purpose of protection oil reservoir oil reservoir to oil reservoir.
In existing simulative experimental instrument, mainly adopt dynamic filtration apparatus to do the static test for contamination of core, the liquid large usage quantity of doing experiment like this, process of the test more complicated trouble.Test with combinations such as rock core fastener and intermediate receptacles exactly in addition, the method test can not be heated, and uses accessory many, and it is pretty troublesome to combine, often unsuccessful test.
Task of the present utility model provides a kind of ring and presses the core test instrument, makes its temperature and pressure condition under can simulation well, can be easily the core of different length be carried out test for contamination.
In order to solve above-mentioned task, the solution that the utility model adopts is: in the upper end of last stationary gland the experimental liquid pressure measuring cylinder is housed, in the upper end of experimental liquid pressure measuring cylinder top cover is housed, have pressure introduction port on top cover.Down on the stationary gland filtrate pipe is being housed, is being connected with screw-rod structure between filtrate pipe and the following stationary gland,, can regulate the degree of depth that filtrate pipe enters packing element by screw-rod structure.In the outer ring of steel bushing and experimental liquid pressure measuring cylinder, heating jacket is housed.
Ring described in the utility model is pressed the core test instrument, and its advantage is the pressure and temperature under the energy simulation well, adopts the ring means of press seals, can carry out contamination of working fluid test to the core of different length, and apparatus structure is simple, and is easy for operation.
Fig. 1 is the annexation figure between the utility model each several part.
Fig. 2 is the diagrammatic cross-section of the utility model rock core fastener part.
Below in conjunction with accompanying drawing the utility model is further described: in the drawings, rock core fastener is made up of steel bushing (10), last stationary gland (7), following stationary gland (13), packing element (8).Packing element is positioned at steel bushing, is provided with a ring in the outside of steel bushing and presses input port (9), and the upper end of last stationary gland is connected with experimental liquid pressure measuring cylinder (6), and the lower end is connected with steel bushing.In the upper end of last stationary gland the experimental liquid pressure measuring cylinder is housed, top cover (4) is housed in the upper end of experimental liquid pressure measuring cylinder, seal by O-ring seal (5) between top cover and the experimental liquid pressure measuring cylinder, have pressure introduction port (3) on the top cover, core (14) is positioned at packing element.Down on the stationary gland filtrate pipe (12) is being housed, is being connected by screw-rod structure between filtrate pipe and the following stationary gland, can regulate the degree of depth that filtrate pipe enters packing element by screw rod.In the outer ring of steel bushing and experimental liquid pressure measuring cylinder heating jacket (11) is housed.During test, at first core is joined in the packing element,, regulates filtrate pipe, make it tightly withstand core, press the input port to add ring by the ring press pump by ring again and press, make packing element encase core tightly according to the length of core, make core around be in sealing state.With filling with experiment work liquid in the experimental liquid pressure measuring cylinder, tighten top cover, the gas of source of the gas (1) after supercharger (2) supercharging, is pressurizeed to experiment work liquid by the pressure introduction port input, heat by heating jacket in addition.Under the condition of simulation well downforce and temperature, experiment work liquid just can be measured the contaminated situation of test core with the infiltration test core.The temperature and pressure that adds gentle pressurization can be decided according to the concrete condition of test, and its maximum pressure can reach 20～50MPa, and maximum temperature can reach 150 ℃, and the internal diameter of packing element is 26mm, and the length range of test core is 30～90mm.
Claims (4)
1, a kind of by source of the gas (1), supercharger (2), last stationary gland (7), following stationary gland (13), the ring that steel bushing (10) etc. are formed is pressed the core test instrument, it is characterized in that being equipped with experimental liquid pressure measuring cylinder (6) in the upper end of last stationary gland, top cover (4) is housed in the upper end of experimental liquid pressure measuring cylinder, on top cover, has pressure introduction port (3).
2, ring according to claim 1 is pressed the core test instrument, it is characterized in that on the stationary gland filtrate pipe (12) being housed down.
3, ring according to claim 2 is pressed the core test instrument, it is characterized in that being connected by screw-rod structure between filtrate pipe and the following stationary gland.
4, ring according to claim 3 is pressed the core test instrument, it is characterized in that in the outer ring of steel bushing and experimental liquid pressure measuring cylinder heating jacket (11) being housed.
