Description
Technical field
The present invention relates to evaluation field under the mirror of rock ore deposit, particularly relate to a kind of fabricating rock gap casting.
Background technology
Body of casting manufacturing technology is before identifying under the mirror of rock ore deposit, the technology of rock sample being carried out pre-service processing.Its step is, at first rock sample is vacuumized, again the epoxy resin that has color is circulated in the glass tube that fills sample, then epoxy resin is cast in the hole of rock and makes its curing by pressurization, take out sample then and separate one by one, at last rock sample is worn into that thin slice is observed at microscopically, image analysis.
The method step that a plurality of rock sample body of castings are made in the prior art is:
1. earlier with a glass tube, sample is put into successively, between sample, put into a mica sheet close to do interval (can be along the cleavage plane strip off), so that at last with sample separation because of mica sheet with the glass tube cross section.Meanwhile, the operator must be on minute book indicates the resemblance of sample one by one, as thickness, whether smooth, information such as complete whether so that when sample separation on this basis with sample with number corresponding playback.
2. again the glass tube mouth of pipe is sealed with rubber stopper, and the access vacuum system vacuumizes vacuum tightness＜6.0 * 10 to sample
-2Behind the Pa, in epoxy resin (the to call epoxy resin in the following text) tail pipe that just can solidify under the colored hot setting condition that under vacuum condition, will prepare, until flooding sample, logical atmosphere, remove rubber stopper, again glass tube is all placed oil cylinder together with sample, be forced into 40MPa, make epoxy resin fully enter rock gap, be warmed up to 90 degree, constant temperature 16 hours makes epoxy resin cure, at last glass tube is taken out and break into pieces, take out the sample of band cured epoxy resin.
3. then sample is separated successively along the mica sheet place, owing to do not have sample number into spectrum on the sample, and sample is wrapped up by opaque colored epoxy resin, sample can only be put earlier successively.After last piece sample is peeled off out, check again.If sum coincide with the gross sample number of putting into, then can be with the corresponding one by one playback of sample.And in case find that sample has and lack that then problem has just occurred, its reason must be the sample that has two or more than two in certain unit, does not separate.Must investigate one by one this moment according to former as record.If do like this or can not find sample, must recover with sample by the shape building sequence one by one before separating in case of necessity.These all are owing to can't carry out the consequence that mark caused of the numbering of sample in body of casting manufacturing process.
At the standard DZS200.35-94 of oil geology Office of Marine Geology of Minitry of Geology and Mineral Resources of the People's Republic of China (PRC) " evaluation of rock gap casting body flake and statistical method ", and among the oil and gas industry standard SY/T6103-2004 of the People's Republic of China (PRC) " the mensuration image analytical method of rock pore structure feature ", all make interval insulant and use with mica sheet.
Because this method of prior art can't realize numbering on the entity of sample own, therefore can only rely on this artificial method of working hard meticulously to differentiate.In order to overcome above-mentioned shortcoming, the part laboratory makes the time spent at the body of casting and does not simply place interlayer, earlier glass tube is broken into pieces during separation, with microtome all samples is cut out a dew point, and then row cutting and separating, but because sample irregular can not guarantee that all samples all has dew point to occur, during the very thin or out-of-shape of sample, the trend of cutting is also uncertain, with the sample chopping, for those hard-earned samples, the loss that causes then cannot be estimated easily.
Summary of the invention
Purpose of the present invention will solve in a plurality of rock body of castings while manufacturing process exactly, and the problem of sample separation and uniqueness sign difficulty improves the efficient that the body of casting is made.
For achieving the above object, the technical solution used in the present invention is: in the process that forms a plurality of rock sample casting works, use the overlapping in the same way placement of two regular polygon art papers that is printed on identical rock sample numbering as interval insulant in the middle of described per two rock samples, simultaneously between two regular polygon art papers, evenly coat release agent, and two art papers are compressed.
In concrete enforcement, said method is further comprising the steps of:
A. in an internal diameter is the glass tube identical with the circumscribed circle diameter of described regular polygon art paper, put into the rock sample of serial number successively, and above each rock sample, face up successively and put two regular polygon art papers of the overlapping placement identical with this rock sample numbering;
B. the glass tube of putting into rock sample and art paper among the above-mentioned steps a is vacuumized, be evacuated to 6.0 * 10
-2Below the Pa, the epoxy resin for preparing is injected glass tube, until covering all rock samples (to exceed about the above 1cm of all rock samples for good) fully, logical then atmosphere places oil cylinder (filling machine oil) with glass tube together with rock sample again, be forced into 40 ± 2MPa, be warmed up to 90 ℃～110 ℃, constant temperature 16 hours makes epoxy resin cure, then glass tube is broken into pieces all rock samples that obtain being solidified togather;
C. the rock sample that obtains among the above-mentioned steps c is beaten along regular polygon copper coin scraps of paper place, obtain the rock body of casting that each has numbering.
In the method for making of a plurality of rock sample body of castings of concrete enforcement:
Described rock sample number is that 1～40 (because this work is pre-treatment work, even a sample also will add interlayer, so that have sample number on the sample, being convenient to the carrying out of subsequent processing) is preferably 15～30.
Described epoxy resin can be according to epoxy resin: triethanolamine: solvent blue=preparation in 100: 18: 1;
Described release agent is all kinds of paste release agents that can be used for the epoxy resin demoulding, as commercially available silicone grease;
The limit number of described regular polygon art paper is preferred 8, and promptly octagon is best.
Because the circumscribed circle diameter of the 8 limit shape scraps of paper is consistent with the internal diameter of placing the mother glass pipe, so although sample is dark, opaque, those lamination scraps of paper of being placed in the middle of each sample also can leak.Sample is rapped along scraps of paper place, and because of the effect of release agent, sample can be separated along the centre of the lamination scraps of paper naturally.The both sides of each sample all have the scraps of paper, but have only the numbering of printing on the scraps of paper of a side corresponding with this sample to reveal, so just can be in the body of casting manufacturing process mark of uniqueness sign of laboratory sample.Thereby guaranteed in the sample separation process corresponding one by one with sample number into spectrum, guaranteed the reliability of testing to have improved the efficient that the body of casting is made greatly.
This method of the present invention is to the additional of standard DZS200.35-94 of oil geology Office of Marine Geology of Minitry of Geology and Mineral Resources of the People's Republic of China (PRC) " evaluation of rock gap casting body flake and statistical method " and the oil and gas industry standard SY/T6103-2004 of the People's Republic of China (PRC) " the mensuration image analytical method of rock pore structure feature " and revises simultaneously, and can consider to include in the new industry standard.
Embodiment
Below, introduce a kind of embodiment of the present invention.Protection scope of the present invention is as the criterion with claims, is not subjected to the restriction of present embodiment.
At first, the numbering that will comprise each rock sample is overlapped (because laser printer uses is carbon dust, so can not dissolved by oils) with art paper laser printing two.For the ease of cutting out, each sample number into spectrum during printing on the art paper up and down at interval all can be to be advisable about 2.8cm.With printing the overlapping in the same way placement of two art papers of same sample numbering is arranged, the one side that promptly is printed on the numbering printed words all up.Below being positioned at, evenly coat the remover silicone grease again above a piece of paper, and compress two pieces of paper and make it paste the jail fully.With the octagon mould sample number is gone out the about 2.9cm of the circumscribed circle diameter of this mould, the final octagon lamination scraps of paper that have sample number into spectrum that form then.Make of in the process at the rock sample body of casting, owing to put into the interval insulant of the octagon lamination scraps of paper of this specification, injectant can flow to bottom sample along tube wall smoothly, and does not influence the interval effect of the scraps of paper.
The rock sample body of casting is made the process of using, be that internal diameter of employing is that the long tube of a 2.9cm glass tube is vertically placed, sample is put into from bottom to top successively, and put the corresponding lamination scraps of paper interval insulant of just having made that is used to identify sample above the sample successively at each, again the glass tube mouth of pipe is sealed with rubber stopper.Insert vacuum system then the glass tube of sealing sample is vacuumized, in the colored epoxy resin tail pipe that under vacuum condition, will prepare in advance, until flooding sample.Remove rubber stopper after vacuumizing end, make glass tube lead to atmosphere, again glass tube is all placed oil cylinder together with sample, be forced into 40MPa, make epoxy resin fully enter rock gap.Be warmed up to 90 degree simultaneously, constant temperature 16 hours makes epoxy resin cure.At last, glass tube is broken into pieces, taken out sample and cleaning.
Because the circumscribed circle diameter of the 8 limit shape scraps of paper is consistent with Sheng sample glass tube internal diameter, so although sample is dark, opaque, but those lamination scraps of paper of being placed in the middle of each sample also can leak, sample is rapped along scraps of paper place, effect because of release agent, sample can be separated along the centre of the lamination scraps of paper naturally, the both sides of each sample all have the scraps of paper, because the double-deck scraps of paper are stacked in the same way, so have only the numbering of printing on the scraps of paper of a side corresponding to reveal on the sample with this sample, so just can be in the body of casting manufacturing process mark of uniqueness sign of laboratory sample.Thereby guaranteed in the sample separation process corresponding one by one with sample number into spectrum, guaranteed the reliability of testing to have improved the efficient that the body of casting is made greatly.
