Description
Technical field
The utility model relates to a kind of rock core displacement test intermediate receptacle, especially a kind of piston dieback container cover that prevents
Rock core displacement test intermediate receptacle.
Background technique
In the oil industry, underground oil and gas resource is produced to be as much as possible, researcher passes through rock core displacement reality
It tests to attempt to obtain more efficient crude oil acquisition method, and the intermediate receptacle of rock core displacement test is under simulation stratum condition to rock
The heart carries out the indispensable device of displacement.But currently used intermediate receptacle can not judge container during rock core displacement test
Inner piston position and lead to the frequent dieback container cover of piston, there are certain security risks.Reasonable design structure of container, it will mention
The service life of high intermediate receptacle improves the stability, accuracy and safety of rock core displacement test.
Summary of the invention
The purpose of this utility model is that be directed to the deficiencies in the prior art, provide a kind of structure is simple, operation just
Rock core displacement test intermediate receptacle prompt and that piston dieback container cover can be prevented.
The utility model solves technical solution used by above-mentioned technical problem: preventing the rock core of piston dieback container cover
Displacement test intermediate receptacle, including outer cylinder, inner cylinder, piston and the container cover for being mounted on outer cylinder both ends, the inner cylinder is each up and down
Equipped with limiting groove, displacement valve and exhaust valve are equipped in the container cover, the piston is equipped with kava structure, the inner cylinder
Upper and lower ends are equipped with pressure sensor, the external indicator light of pressure sensor.
Further, six kava structures are uniformly arranged on the piston cylindrical surface, two adjacent kava structure sides
To opposite.
Further, the kava structure is made of slips, limit eave tile, slips is set to T-type by limiting eave tile
In slot.
Further, being equipped with device for ejecting inside the kava structure, the device for ejecting includes two springs, connection
Fritter, the spring one end are fixed on piston, the other end with connect fritter be connected and side by side discharge.
Further, the limiting groove size being arranged on the inner cylinder, depth and slips size match.
Further, the outer cylinder lower part is equipped with base support, entire intermediate receptacle is mounted on base support.
The utility model need not judge that the movement position of piston during rock core displacement test passes through using kava structure
Device for ejecting pops up slips, blocks in the limiting groove being arranged on the inner cylinder, prevents piston dieback container cover, and structure is simple, grasps
Facilitate, improves the safety of device in experimentation.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the piston schematic diagram that kava structure is had in the utility model embodiment；
It is as shown in the figure: 1- outer cylinder, 2- inner cylinder, 3- container cover, 4- base support, 5- displacement valve, 6- exhaust valve, 7- piston,
8- kava structure, 9- limiting groove, 10- slips, 11- limit eave tile, 12-T type groove, 13- spring, 14- connection fritter.
Specific embodiment
The utility model is done with reference to the accompanying drawings and examples and is further illustrated.
As shown in Figs. 1-2, prevent the rock core displacement test intermediate receptacle of piston dieback container cover, including outer cylinder 1, inner cylinder 2,
Container cover 3 and piston 7, about 2 inner cylinder are respectively provided with limiting groove 9, and wherein 9 size of limiting groove, depth and slips 10 are big
It is small to match, displacement valve 5 and exhaust valve 6 are equipped in the container cover 3, the piston 7 is equipped with kava structure 8, the card
It is equipped with device for ejecting inside tile structure 8, slips 10 can be popped up and be stuck in limiting groove 9, limitation piston 7 continues to move to, institute
It states inner cylinder upper and lower ends and is equipped with pressure sensor, the external indicator light of pressure sensor can set the pressure limit in inner cylinder 2
Value, when pressure sensor detects that pressure reaches pressure limit value in inner cylinder 2, indicator light is bright, then artificial to close pump pressure release.
As shown in Fig. 2, the preferred mounting means of kava structure 8 is, six slips are uniformly arranged on 7 cylindrical surface of piston
Structure 8, and two adjacent kava structures 8 are contrary.The kava structure 8 is made of slips 10, limit eave tile 11, wherein
Slips 10 is arranged in T-slot by limit eave tile 11.
The preferred mounting means of device for ejecting is a device for ejecting to be respectively provided with inside the kava structure 8, and be mounted on
Between slips 10 and limit eave tile 11.Wherein the specific embodiment of device for ejecting is that the device for ejecting includes two springs
13, fritter 14 is connected, described 13 one end of spring is connected with piston 7, and one end is connected with fritter 14 is connect, and is arranged in juxtaposition, described
Connection fritter 14 is fixed on slips 10.When (downward) moves to the limiting groove 9 on inner cylinder 2 to piston 7 upwards, device for ejecting
Spring 13 extend, push connection fritter 14 slips 10 is popped up, be stuck in limiting groove 9.When (upward) movement downwards of piston 7
When leaving limiting groove 9, slips 10 is withdrawn along the motion on a slope of limiting groove 9, and compressed spring 13 is shunk, until slips 10 is all
It withdraws, piston 7 is detached from limiting groove 9.
For the ease of the placement of intermediate receptacle, preferred embodiment is that the outer cylinder lower part is equipped with base support 4, whole
A intermediate receptacle is mounted on base support 4.
