Abstract
The invention relates to a rubber-strip-plugging core protection method which includes the steps: placing an aluminum alloy shape-preserving cylinder and a core in the cylinder on a pipe frame, and intercepting one section of aluminum alloy shape-preserving cylinder; tightly sealing one end of the intercepted aluminum alloy shape-preserving cylinder by the aid of a rubber cover and a hoop; enabling the aluminum alloy shape-preserving cylinder to vertically stand, and enabling the core to be at the center; sequentially plugging one end of each rubber strip into annular gaps between the core and the aluminum alloy shape-preserving cylinder, and inserting one end of each rubber strip to the bottom of the annular gaps; tightly sealing an opening end of the aluminum alloy shape-preserving cylinder by the aid of a rubber cover and a hoop. The protection method has the advantages that the rubber strips serve as core protection media, the core leaving from the cylinder cannot be directly taken out and poured into a core box and is protected by the aid of a fixing mode of the rubber strips, core shapes cannot be damaged when the aluminum alloy shape-preserving cylinder is transferred and transported, the core is protected, intrusion of other impurities is effectively prevented, and cores with good rock forming performance are effectively protected. The method is simple to operate, time is saved, and accuracy measuring geologic parameters is ensured in later laboratories.
Description
Art
It is a kind of rock core post-processing technology that formation core obtained to drilling and coring delivery is protected the present invention relates to oil and gas well drilling coring operation supporting technology field, can apply to all kinds of drilling and coring deliveries.
Background technology
The special coring tool used in drilling process subsurface rock it is blocking get on ground, this process is referred to as drilling and coring delivery.Lithology, porosity, permeability, the saturability of rock can be determined by rock core, the physicochemical properties such as wettability and electric conductivity, intuitively Study of The Underground construction and lithotope, understand fluid properties therein etc..
Drilling and coring delivery obtains rock core reset condition to be affected by factors such as purpose layer depth, stratigraphic horizon, compaction states, is distinguished very big.The rock core for managing obvious and cementing poor stratum acquisition layer by layer on ground is usual in the form of sheets, and these layers manage cementing weaker rock core and are highly prone to destroy during rock core goes out cylinder, packaging and transhipment.On the one hand rocking during transhipment etc., shake and causes rock core radially cracking, lose original physical state；Another aspect rock core goes out introduced contaminants in cylinder, transport process can enter rock core, cause the formation parameter of final acquisition inaccurate.
The content of the invention
It is an object of the invention to solve above-mentioned technical problem, there is provided a kind of drilling and coring delivery scene protection goes out the plug glue strip type rock core guard method that a rock core is not damaged with pollution.
The technical scheme is that：
One kind plug glue strip type rock core guard method, including:The conformal cylinder of aluminium alloy is placed on pipe support together with rock core in cylinder, a section of the conformal cylinder of aluminium alloy is intercepted；Conformal cylinder one end of aluminium alloy of intercepting is tamping with Jiao Gai and clip；It is the conformal cylinder of aluminium alloy is upright and make rock core placed in the middle；During one end of several adhesive tape to be filled in successively again the annular gap of rock core and the conformal cylinder of aluminium alloy, and it is inserted into bottom；Finally it is tamping the openend of the conformal cylinder of aluminium alloy with Jiao Gai and clip again.
Such scheme is further included：The length for intercepting the conformal cylinder of aluminium alloy is 1 meter, and the length of same adhesive tape is also 1 meter, and adhesive tape fills in quantity more than 8 and evenly distributed.
Present invention has the advantages that：Medium is protected as rock core using adhesive tape, it is not to directly take out to pour core tray into but protect rock core by the way of plug adhesive tape is fixed to go out a rock core, and the form that rock core can be avoided in the conformal cylinder of transfer transport aluminium alloy is destroyed；Protect rock core and effectively prevent the intrusion of other impurities；For there is good specific aim into the preferable rock core of lithology；This method is simple to operate, time-consuming；It is a kind of high-quality, method efficiently, practical, it is ensured that later experiments room measures the accuracy of geologic parameter.
Specific embodiment
With reference to embodiment, the present invention will be further described.
After the completion of drilling and coring delivery operation, the conformal cylinder of aluminium alloy is placed on pipe support together with rock core in cylinder when going out the heart, the conformal cylinder of aluminium alloy is cut into one meter of short cylinder according to one meter of length.One end of short cylinder is tamping with Jiao Gai and clip, and establishing short cylinder makes rock core placed in the middle, and one end of 8 rice glue bars is filled in successively and uniformly in the annular gap of rock core and the conformal cylinder of aluminium alloy, and is inserted into bottom；Finally it is tamping openend with Jiao Gai and clip again.Now i.e. can safety transhipment rock core.
Claims (2)
1. a kind of glue strip type rock core guard method of plug, is characterized in that including:The conformal cylinder of aluminium alloy is placed on pipe support together with rock core in cylinder, a section of the conformal cylinder of aluminium alloy is intercepted；Conformal cylinder one end of aluminium alloy of intercepting is tamping with Jiao Gai and clip；It is the conformal cylinder of aluminium alloy is upright and make rock core placed in the middle；During one end of several adhesive tape to be filled in successively again the annular gap of rock core and the conformal cylinder of aluminium alloy, and it is inserted into bottom；Finally it is tamping the openend of the conformal cylinder of aluminium alloy with Jiao Gai and clip again.
2. plug according to claim 1 glue strip type rock core guard method, is characterized in that：The length for intercepting the conformal cylinder of aluminium alloy is 1 meter, and the length of same adhesive tape is also 1 meter, and adhesive tape fills in quantity more than 8 and evenly distributed.
