Abstract
The utility model discloses a seam device is made in manual work of hyposmosis rock core, including base and top cap, wherein offered the rock core groove on the base, the bottom in rock core groove is inlayed and is equipped with down the cutter, and the top cap is inserted and is established on the base, inlays on the top cap that corresponding basal sapping cutter spacing was put and is equipped with the cutter. Wear to be equipped with the screw rod on the lateral wall in rock core groove, the top of screw rod is connected with the grip block. The top cap passes through the fixed column and is connected with the base. Beneficial effect: after using the device, can realize the manual work and make seam in -process crack both sides rock core and do not produce the dislocation, and then not change the inner structure of man -made fracture, the protection of very big limit the initial state of rock core, guaranteed the accuracy of experimental data.
Description
Technical field
The utility model relates to one and makes seam device, particularly a kind of flow in low permeability core man seam device.
Background technology
Reservoir sensitivity parameters such as (comprise water-sensitive, speed is quick, salt is quick) acid-sensitive and alkali are quick is the important parameter that oil gas field guiding construction is produced, the rate of change of the permeability that its evaluation principle mainly changes the parameter such as displacing medium or displacement flow velocity and records under constant temperature, finally determines its susceptibility.Therefore the evaluation basis of susceptibility is exactly the mensuration of rock core liquid infiltration rate.
Along with going deep into of China's oil-gas exploration and development, the reservoir that we face is towards the development of hypotonic, ultra-permeable reservior, and hypotonic, ultra-permeable reservior rock core liquid infiltration rate is 0.1 × 10
-3μm
2below, and evaluate multi-functional rock core displacement device that rock core liquid infiltration rate uses at present and limit displacement pressure for≤70Mpa, therefore sensitivity assessment experiment cannot be carried out for some rock cores that liquid infiltration rate is extremely low, displacement pressure is high, so a kind of device must be designed in order to increase the liquid infiltration rate of rock core, and then evaluate its susceptibility.By investigation in early stage, it is that stitch is made in shearing that rock core conventional at present makes seam method.What the method was used make, and seam apparatus structure is simple, easy and simple to handle.Man-made fracture flow in low permeability core being manufactured to high permeability can be realized.But this device in use very easily causes the rock core of both sides, crack to misplace, and causes the change of man-made fracture inner structure, and fracture width is excessive causes comparatively big experiment error.
Summary of the invention
The purpose of this utility model is making rock core dislocation in man-made fracture both sides in seam process to solve existing rock core man seam device, cause the change of man-made fracture inner structure, and fracture width is excessive causes the problem compared with big experiment error and a kind of flow in low permeability core man seam device that provides.
The flow in low permeability core man seam device that the utility model provides includes base and top cover, and wherein base offers rock core groove, the bottom of rock core groove is embedded with lower cutter, and top cover is plugged on base, and the top cover of corresponding lower cutter position is embedded with upper cutter.
The sidewall of rock core groove is equipped with screw rod, and the top of screw rod is connected with grip block.
Top cover is connected with base by fixed leg.
Principle of work of the present utility model:
First rock core groove on base is put into by waiting to make seam rock core, lower cutter is contacted with bottom rock core, then the screw rod on precession rock core groove sidewall makes the grip block of screw tip that rock core is fixed, adjustment both sides screw rod screw-in length, guarantees that the lower cutter on base aims at rock core center line, then top cover, the upper cutter on top cover is made to aim at the center line on rock core top, after completing above work, load normal force on top cover top, until rock core produces micro-cracks.
The beneficial effects of the utility model:
After using this device, both sides, crack rock core in man seam process can be realized and do not produce dislocation, and then not change the inner structure of man-made fracture, protect the virgin state of rock core greatly, ensure that the accuracy of experimental data.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
1, base 2, top cover 3, rock core groove 4, lower cutter 5, upper cutter 6, screw rod 7, grip block 8, fixed leg.
Embodiment
Refer to shown in Fig. 1:
The flow in low permeability core man seam device that the utility model provides includes base 1 and top cover 2, wherein base 1 offers rock core groove 3, the bottom of rock core groove 3 is embedded with lower cutter 4, and top cover 2 is plugged on base 1, and the top cover 2 of corresponding lower cutter 4 position is embedded with upper cutter 5.
The sidewall of rock core groove 3 is equipped with screw rod 6, the top of screw rod 6 is connected with grip block 7.
Top cover 2 is connected with base 1 by fixed leg 8.
Principle of work of the present utility model:
First rock core groove 3 on base 1 is put into by waiting to make seam rock core, lower cutter 4 is contacted with bottom rock core, then the screw rod 6 on precession rock core groove 3 sidewall makes the grip block 7 on screw rod 6 top that rock core is fixed, adjustment both sides screw rod 6 screw-in length, guarantees that the lower cutter 4 on base 1 aims at rock core center line, then top cover 2, the upper cutter 5 on top cover 2 is made to aim at the center line on rock core top, after completing above work, load normal force on top cover 2 top, until rock core produces micro-cracks.
