Abstract
The invention discloses a sealed shape-retaining coring fresh-keeping processing mechanism for a rock core, and a fresh-keeping processing method thereof. The mechanism comprises a PVC liner, a preservative film, an aluminium-foil paper and an immobilized rubber shell which are successively disposed from inside to outside. The upper end of the hemicycle cross section of the internal PVC liner is open and the interior of the PVC liner is used to store the rock core; and the preservative film is disposed outside the PVC liner and covers the upper side surface of the rock core at the upper-end opening of the PVC liner. The mechanism helps to overcome the disadvantages that: the conventional rock core has severe fragmentation and hydrocarbon losses, and a sampling analysis test cannot be effectively performed once more; and the mechanism and the fresh-keeping processing method not only helps to reduce weathering and fragmentation of the rock core, but also helps to reduce hydrocarbon loses of the rock core interior to make the rock core keep the original state for a long time and further to have multiple sampling analysis tests and research carried out effectively at any time.
Description
Technical field
The rock core Preservation Treatment technology that the present invention relates to core, the airtight guarantor's type that specifically relates to the particular lithologics such as understressed sand, oil-bearing sand, rock salt and cream rock core rock core Preservation Treatment structure and fresh-keeping treating method thereof.
Background technology
Rock core is the firsthand information the most directly perceived, the truest and the most valuable in the exploratory development research field.For a long time, the rock core that airtight guarantor's type is cored and taken out through after sampling once, is directly exposedly put into core tray and is preserved, and there is no the measure of effective rock core conservation treatment, and most of rock core is detrition now, and fragmentation is serious has all become powder.Even indivedual more completely rock cores are arranged, inner oil gas vanishes already, and the data of sampling analysis and test have lost practical significance again.
Along with the development of science and technology, understanding and the improving constantly of research level need to be carried out repeatedly observation, analysis and research to rock core.The rock core of preserving at present can not effectively carry out the test of sampling analysis again because fragmentation is serious, wants to satisfy the requirement of assay and research, can only drop into a huge sum of money and again core.
In view of this, for the problems referred to above, a kind of airtight guarantor's type reasonable in design and that effectively improve above-mentioned disappearance core rock core Preservation Treatment structure and fresh-keeping treating method thereof are proposed.
Summary of the invention
The object of the present invention is to provide airtight guarantor's type core rock core Preservation Treatment structure and fresh-keeping treating method thereof, overcome existing disintegration of core serious, oil gas scatters and disappears, can not effectively carry out the deficiency of the test of sampling analysis again, the present invention not only can reduce the detrition of rock core, and the oil gas that can reduce rock core inside scatters and disappears, and rock core can be remained under virgin state for a long time, can effectively carry out at any time repeatedly sampling analysis test and research.
In order to reach above-mentioned purpose, the present invention adopts following technical scheme: airtight guarantor's type rock core Preservation Treatment structure of coring, this structure sets gradually pvc bushing pipe, preservative film, aluminium-foil paper, solid seal glue shell from the inside to the outside.
The semi-circular cross-section upper end of the pvc bushing pipe of described inside is opening form and at pvc bushing pipe internal storage rock core, described preservative film is in the pvc bushing pipe outside and covers simultaneously the rock core upper side at pvc bushing pipe upper end open place.
In order to reach another purpose, the present invention adopts following technical scheme: a kind of airtight guarantor's type is cored rock core Preservation Treatment structure to the fresh-keeping treating method of rock core, and its step is as follows:
Airtight guarantor's type rock core of coring is divided into one meter one section and is placed in semicircular bushing pipe, and bushing pipe plays the effect of fixing, support and guarantor's type to rock core;
Rock core is sealed with preservative film in the bushing pipe outside, prevented that the oil gas of rock core inside outwards scatters and disappears;
With aluminium-foil paper, rock core is sealed again outside preservative film, prevented that external environment condition from having a negative impact to rock core;
Seal with the sealing of adhesive tape with aluminium-foil paper, prevent that rock core is poorly sealed;
On aluminium-foil paper, mark about well-name, the well section relevant information of rock core, is grasped when being conducive to again sample;
The rock core of sealing is immersed in the fresh-keeping glue body of sealing carry out solid envelope, formation solid seal glue shell makes rock core thoroughly and external environment condition completely cuts off;
Rock core after processing through preservation technique is put into core tray and is preserved.
Compared to prior art; the rock core that the airtight guarantor's type of the present invention is cored and taken out; through once the sampling after; the employing bushing pipe supports; preservative film and aluminium-foil paper are sealed, and the technical method of solid seal glue freshness seal carries out rock core sealing Preservation Treatment, and inner rock core is under the protection of multilayered medium; thoroughly isolated with extraneous air, thus reach the purpose of long preservation and protection.Airtight guarantor's type is cored rock core after processing through preservation technique, and detrition and the oil gas that can reduce rock core scatter and disappear, and rock core can be remained under virgin state for a long time, can effectively carry out at any time repeatedly sampling analysis test and research.

Embodiment
Relevant detailed description of the present invention and technology contents coordinate description of drawings as follows, yet accompanying drawing only provides the use of reference with explanation, and the present invention is limited.
According to shown in Figure 1, airtight guarantor's type rock core Preservation Treatment structure of coring, this structure sets gradually pvc bushing pipe, preservative film, aluminium-foil paper, solid seal glue shell from the inside to the outside.The semi-circular cross-section upper end of the pvc bushing pipe of described inside is opening form and at pvc bushing pipe internal storage rock core, described preservative film is in the pvc bushing pipe outside and covers simultaneously the rock core upper side at pvc bushing pipe upper end open place.
Airtight guarantor's type is cored rock core Preservation Treatment structure to the fresh-keeping treating method of rock core, and its step is as follows:
Airtight guarantor's type rock core of coring is divided into one meter one section and is placed in semicircular bushing pipe, and bushing pipe plays the effect of fixing, support and guarantor's type to rock core;
Rock core is sealed with preservative film in the bushing pipe outside, prevented that the oil gas of rock core inside outwards scatters and disappears;
With aluminium-foil paper, rock core is sealed again outside preservative film, prevented that external environment condition from having a negative impact to rock core;
Seal with the sealing of adhesive tape with aluminium-foil paper, prevent that rock core is poorly sealed;
On aluminium-foil paper, mark about well-name, the well section relevant information of rock core, is grasped when being conducive to again sample;
