Abstract
The invention relates to a method for manufacturing a small-size rock slice sample. The method mainly solves the problems that the existing slice sample is single in identification and the slice identification efficiency cannot be fully exerted. The method is characterized in that: the method comprises the following steps: a. firstly, drilling a rock sample into a small cylindrical rock core with the diameter of 5-8 mm according to different lithologies; b. b, slicing the small cylindrical rock core drilled in the step a, wherein the thickness of the small cylindrical rock core is 1.0-2.0 mm; c. sticking the cut rock slices on a glass slide; d. c, putting the rock slice sample on the glass slide in the step c on a rock slice grinding machine for grinding; e. and (3) carrying out coarse grinding, fine grinding and fine grinding on the rock slice sample on the glass slide to reach the standard thickness of 0.03 +/-0.1 mm. According to the method for manufacturing the small-size rock slice sample, the multiple rock slice samples can be manufactured by one glass slide, so that the core loss is reduced, and the comparison and identification are convenient.
Description
Technical field
The present invention relates to a kind of core sample method for making in In Oil Field Exploration And Development technical field, especially a kind of small size petrographic thin section sample production method.
Background technology
Rock core is rare and valuable geology geological material, and it can reflect architectural feature and the mineral composition of rock stratum truly.Drilling and coring delivery, every block rock core somewhat expensive, drilling through core sample if a large amount of, is the huge waste to rock core.Small size petrographic thin section sample can save a large amount of rock core, general petrographic thin section sample is all that stickup one piece of diameter is the sample that 25mm rock grinds on one piece of microslide, such thin slice makes in relative technique comparatively simple, and the rock sample ground is all single sample.But because sample diameter is relatively large, time-consuming in the process ground, effort, produces the inclined phenomenon of mill often.When doing thin section identification, one piece of sample is just corresponding to one piece of chip sample, can not contrast qualification, can not improve determination rates for same layer position.
Summary of the invention
The invention reside in overcome in background technology and there is the single problem of rock sample that existing petrographic thin section manufacture craft simply grinds, and provide
oneplant small size petrographic thin section sample production method.This small size petrographic thin section sample production method, one piece of microslide can produce how soon petrographic thin section sample, reduces rock core loss, improves thin section identification efficiency, be convenient to carry out contrast and identify.
The present invention solves its problem and reaches by following technical scheme:
oneplant small size petrographic thin section sample production method, comprise the following steps:
A, first according to the difference of lithology, rock sample is drilled to the small column rock core of diameter 5 ~ 8mm;
B, cut into slices to the small column rock core be drilled in step a, thickness is at 1.0 ~ 2.0mm;
C, by the rock cut down section adhere in glass slide;
D, the rock section sample on microslide in step c is put on rock wafer lapping machine grinds;
Rock section sample on e, microslide reaches standard thickness 0.03 ± 0.1mm after corase grind, fine grinding, fine grinding.
The present invention can have following beneficial effect compared with above-mentioned background technology: this small size petrographic thin section sample production method, be that the rock sample being stained with the similar and different lithology of polylith with one piece of microslide carries out grinding petrographic thin section sample, such chip sample tool has the following advantages.The first, for the rock core of same well, contrast qualification can be carried out according to identical lithology, identical layer position petrographic thin section; The second, for different well, identical layer position, different lithology can carry out thin section identification; Three, thin section identification is carried out for the lithology that different well is identical: four, for different well can be same layer position, the core sample of different layers position sample of laminating carries out thin section identification.Five, identification equipment can be made to play maximum qualification function, improve determination rates, make thin section identification more rationally, science more.Six, the disposable chip sample that grinds can carry out lithology independent assortment as required, exactly polylith lithology is placed on same and carries preparation efficiency thin slice grinding and improves petrographic thin section, owing to using small size chip sample, the use amount of rock core can be saved.The method existing equipment, cost are low, and simple to operate being easy to is grasped, and reduces rock core loss, compensate for the deficiency of current adding rock chip sample method.
