Directly affect cementing quality, but to cementing quality play a decisive role be Behavior of Hardened Cement Paste with casing or Behavior of Hardened Cement Paste and stratum it
Between cementing strength.But there is presently no it is a kind of it is simple and practical can test Behavior of Hardened Cement Paste and casing or Behavior of Hardened Cement Paste and stratum it
Between cementing strength device.
Utility model content
In view of the drawbacks described above of the prior art, the technical problem to be solved by the utility model is to provide a kind of cement mortars
Cylinder is conserved, Behavior of Hardened Cement Paste can be tested and adheres to the cementing strength between filter cake interface, rather than Behavior of Hardened Cement Paste itself, before flushing
The flushing effect of flushing liquor is evaluated in the variation of cementing strength afterwards.
To achieve the above object, the utility model provides a kind of cement mortar maintenance cylinder, including bottom cover, outer barrel, bolt, interior
Cylinder, head cover, tile, steel plate, screw rod, the inner cylinder lower part connect with bottom cover, and the inner cylinder top connects with head cover, the bottom
Lid, head cover connect with inner cylinder installs outer barrel between the both ends to extend out respectively, and the part in inner cylinder is located on the inside of the bottom cover
Tile is set, and the inside of top cover is located at the setting of the part in inner cylinder steel plate, and the tile, steel plate and inner cylinder are formed closed
Cement mortar is contained in space.
Further, one end of the bottom cover and outer barrel is connected by screw rod, and the screw rod is tightened by bolt；The top
Lid is connect with the other end of outer barrel by screw rod, and the screw rod is tightened by bolt.
Further, the outer barrel is "u"-shaped.
Further, the centrally disposed extravasating hole of the steel plate.
Further, two pieces of strong magnets are arranged with steel plate joint in the head cover.
Further, the inner cylinder is made of the component of two semi-cylindrical in configuration.
The utility model has the beneficial effects that：
The utility model can test Behavior of Hardened Cement Paste and adhere to the cementing strength between filter cake interface, rather than Behavior of Hardened Cement Paste sheet
Body evaluates the flushing effect of flushing liquor, simple in structure, convenient test, reliability by the variation of cementing strength before and after flushing
Well, cost is relatively low, efficiently solves the deficiencies in the prior art.
The technique effect of the design of the utility model, concrete structure and generation is made furtherly below with reference to attached drawing
It is bright, to be fully understood from the purpose of this utility model, feature and effect.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the steel plate structure schematic diagram of the utility model.
Fig. 3 is the cap structure schematic diagram of the utility model.
Specific implementation mode
As shown in Figure 1, a kind of cement mortar conserves cylinder, including bottom cover 1, outer barrel 2, bolt 3, inner cylinder 4, head cover 5, tile 6, steel
Plate 8, screw rod 9,4 lower part of the inner cylinder connect with bottom cover 1, and 4 top of the inner cylinder connects with head cover 5, the bottom cover 1, head cover 5
Connect with inner cylinder 4 and outer barrel 2 is installed respectively between the both ends to extend out, 1 inside of the bottom cover is located at the part setting in inner cylinder 4
Tile 6,5 inside of the head cover are located at the part in inner cylinder 4 and steel plate 8 are arranged, what the tile 6, steel plate 8 and inner cylinder 4 were formed
Cement mortar 7 is contained in confined space.
In the present embodiment, the bottom cover 1 is connect with one end of outer barrel 2 by screw rod 9, and the screw rod 9 is twisted by bolt 3
Tightly；The head cover 5 is connect with the other end of outer barrel 2 by screw rod 9, and the screw rod 9 is tightened by bolt 3.
In the present embodiment, the outer barrel 2 is "u"-shaped.
In the present embodiment, 8 centrally disposed extravasating hole 81 of the steel plate.
In the present embodiment, two pieces of strong magnets 51 are arranged with 8 joint of steel plate in the head cover 5.
In the present embodiment, the inner cylinder 4 is made of the component of two semi-cylindrical in configuration.
The use principle of the utility model is：
1. by elevated-temperature seal fat is smeared on cement tube inner cylinder, bottom cover, head cover, first, sealing needs, after two are easy for maintenance
Dismounting is taken out.
2. among inner cylinder is put into outer barrel, bottom cover is covered, tightens bottom cover screw.
3. the tile with filter cake after flushing is placed in inner cylinder bottom, suitable cement mortar is subsequently poured into (by API 10B systems
Standby, cement-slurry method is cementing design formula), finally place into steel plate.By extra cement mortar from the extravasating hole at steel plate center
