Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, the present embodiment provides a high-temperature high-pressure imbibition device, which includes an imbibition holder cylinder, a metering tube, a collection funnel and an injection pump; the inner part of the barrel of the imbibition holder is used for accommodating a rock core, the smaller end of the collecting funnel is connected with the bottom end of the metering tube, and the larger end of the collecting funnel is positioned right above the rock core; the injection pump is used for injecting displacement liquid into the imbibition holder cylinder.
In this embodiment, as shown in fig. 1, the measuring tube is a glass tube, and a suitable measuring glass tube 12 is selected, connected to the stopper 13 of the holder, and mounted on the barrel 5 of the imbibition holder, and the collecting funnel 11 is mounted. The rock core 9 is fixed on the lower plug 8 of the holder, the lower plug 8 of the holder and the cylinder 5 of the imbibition holder are sealed in place, and the cylinder 5 of the imbibition holder is ready to be injected with replacement liquid.
The constant-speed constant-pressure pump 15 can be used as a pressurizing pump for simulating formation pressure for a rock core, and can also be used as a constant-pressure device for the internal pressure of the gripper, if the internal pressure of the gripper is increased, the constant-speed constant-pressure pump 15 can automatically withdraw to a set pressure value, and if the internal pressure of the gripper is reduced, the constant-speed constant-pressure pump 15 can automatically enter to the set pressure value. And (3) pre-filling the displacement liquid into the cylinder 5 of the imbibition gripper by using a constant-speed constant-pressure pump 15, and opening the emptying valve 1 of the metering tube and the emptying valve 2 of the displacement liquid until the two emptying valves have liquid flowing out, and stopping filling. And then injecting oil from the metering tube emptying valve 1 into the metering glass tube 12 to form a volume metering initial interface (the initial interface must exceed the scale line at the uppermost end of the metering glass tube), closing the metering tube emptying valve 1 and the replacement liquid emptying valve 2, and then starting metering, wherein the volume metering can be realized by means of, but not limited to, adopting a camera system to perform visual image metering through a high-pressure window 4.
The displacement liquid is heated to a set temperature, the constant-speed constant-pressure pump 15 is used for pressurizing the imbibition holder cylinder 5 to a set pressure and setting a constant-pressure mode until the temperature is stable, and the system detects the pressure and the temperature in the imbibition holder cylinder 5 through the pressure sensor 3 and the temperature sensor 6 at any time.
Oil drops seeped out in the test process can slowly gather and grow until the oil drops are separated from the surface of the rock core 9, the oil drops rise and are collected into the metering glass tube 12 through the collecting funnel 11, the oil drops can be subjected to gravity separation in the metering glass tube 12 due to different oil-water specific gravities, the oil drops float upwards and are finally mixed with oil on an initial metering interface to form the liquid level change of the oil, and the volume of the oil drops is calculated through the camera shooting metering system.
When some oil drops can not leave the core 9 freely, the pneumatic injection mechanism needs to be opened to inject the oil drops on the surface of the core when necessary. As shown in fig. 2 and 3, a pneumatic piston cylinder 7 is connected, one end of the pneumatic piston cylinder 7 is connected to the displacement liquid in the imbibition holder cylinder 5, the other end of the pneumatic piston cylinder 7 is connected to an injection pipe 10 in the imbibition holder cylinder 5, and the pneumatic piston cylinder 7 sucks the displacement liquid in the imbibition holder cylinder 5 and injects the displacement liquid to the surface of the rock core 9 through the injection pipe 10 to wash away oil droplets on the surface of the rock core 9 during reciprocating motion. In order that the pneumatic piston cylinder 7 injection tube cannot suck in oil droplets, it is possible to arrange with the pneumatic valve 17 that the suction tube 16 is always in the suction state and the injection tube is always in the spray state (as shown in fig. 2 and 3). The reciprocating movement of the pneumatic piston cylinder 7 ensures that the total amount of displacement fluid in the holder is constant and therefore does not affect the pressure conditions in the holder.
The measuring method needs to calibrate the volume of the glass tube 12 in advance, and the gas calibration method comprises the steps of carving two scale marks on the upper part and the lower part of the glass tube, measuring the volume total amount between the two scale marks by adopting a high-precision balance, finding the two scale marks on an image by utilizing a camera, distributing image pixels, and measuring the imbibition amount of a rock core through a pixel position corresponding to an interface.
