Abstract
The utility model discloses a combined connecting rock core model pipe used for a laboratory in the petroleum industry, which comprises rock core model pipes. A sampling hole opening and a pressure hole are formed on each rock core model pipe respectively, and the rock core model pipes are connected and assembled through a connecting pipe; after the rock core model pipes are connected and assembled through the connecting pipe, the combined connecting rock core model pipe meets the spatial requirement of a thermostat; and the connecting pipe is connected with the rock core model pipe in a flange sealing manner, grooves are formed in the end surfaces of two connecting ends of the connecting pipe respectively, and sealing rings are arranged in the grooves, so that close connection between the connecting pipe and the shorter rock core model pipe is ensured. The length of the rock core model pipe can be obtained by changing the number of the connected shorter rock core model pipes according to the demands of test; the combined connecting rock core model pipe meets the demands of test on the long rock core model pipes at high temperature and can be used for various physical simulation experiments (such as improvement of indoor recovery ratio, water shutoff and the like) in the petroleum industry, is convenient for filling the quartz sand and provides great convenience for processing and manufacturing the stimulation rock core.
Description
Technical field
The utility model relates to the indoor Physical Experiment equipment of petroleum industry, and the rock core model pipe that particularly is connected will be simulated the rock core filling in pipe, is used for the indoor physical simulation test.
Background technology
In the physics laboratory of petroleum industry, rock core is placed on the oil production technology experiment of carrying out in the constant temperature oven under the simulated formation temperature, be regular experimental work.Owing to the reasons such as space constraint of physics laboratory, the effective dimensions of constant temperature oven can not be very big, and the effective length of constant temperature oven is generally about 1 meter.But in the research of physical simulation experiments such as the displacement of reservoir oil and stifled accent, the length of the used model basket that experimentizes needs to reach several meters even tens meters sometimes.Clearly, constant temperature oven has limited the use of long rock core model pipe under the simulated formation temperature.In such cases, the method that can only adopt the ribbon heater to be wrapped in single long rock core model pipe outer wall in the experiment solves the problem that the rock core model pipe is heated, but this kind method causes long rock core model pipe to be heated inhomogeneous, can not satisfy the requirement of experiment to thermally equivalent, single rock core model pipe is long simultaneously, manufactures the also very inconvenience of simulation rock core at casing pack silica sand.As several rock core model pipe are connected with flexible pipeline, although the rock core model pipe that connects is placed in the constant temperature oven easily together, pipeline influences experiment effect to the loss of Experimental Flowing Object build-up of pressure.In order in constant temperature oven, to use the better simulate formation situation of long rock core model pipe to experimentize, must transform the structure of existing rock core model pipe.
Summary of the invention
The purpose of this utility model provides the rock core model pipe that is connected, and several shorter rock core model pipe are connected, and makes it can satisfy the requirement of experiment to rock core model pipe length, can make the rock core model pipe be heated evenly under the simulated formation temperature again.
The purpose of this utility model is achieved in that the rock core model pipe that is connected comprises the rock core model pipe, and the rock core model pipe is provided with sampling aperture and pressure tap, and the rock core model pipe is assembled by connecting pipe.
According to the technical scheme that the utility model provides, can obtain following useful effect: the utility model has adapted to the space requirement of constant temperature oven after by connecting pipe the rock core model pipe being assembled.Adopt the flange form mode that is tightly connected between connecting pipe and the rock core model pipe, the end face of two links of connecting pipe is all fluted, built-in O-ring seal, guaranteed combining closely between connecting pipe and the shorter rock core model pipe port plane, also overcome with pipeline and connect the pressure loss that the rock core model pipe causes experiment and the influence of fluid.The rock core model pipe that all are short and the length sum of connecting pipe are the length of the whole rock core model pipe that is connected.According to the experiment needs, the length of required rock core model pipe can obtain by the radical that changes the shorter rock core model pipe that is connected.It is simple and reliable to have short rock core model pipe connection, and total length is easy to adjust, and characteristics such as the rock core model pipe is heated evenly are connected.Satisfied under the high temperature the test needs of long rock core model pipe, can be used in the physical simulation experiments such as indoor raising recovery ratio of petroleum industry and water plugging and profile controlling.Use short rock core model pipe simultaneously, the silica sand filling is convenient, and the processing that greatly facilitates the simulation rock core is manufactured.
