Embodiment Construction

[0048] The devices used in this embodiment are respectively:

[0049] Trace displacement pump 1, ISCO-100DX type, the flow range is 0.01μl / min-25ml / min, the pressure range is 0-70Mpa, the flow rate is stable, and can meet the requirements of various simulation speeds.

[0050] Microcosmic simulation model 2, using techniques such as photography and plate making, the pore structure on the thin slice of the core casting body is enlarged and etched on a flat glass plate, and then a flat glass model is made by bonding and sintering, with a size of 4cm×4cm , and its pore structure is similar to that of reservoir rock.

[0051] Microscopic environment 3, objective lens multiples of 1×, 4× and 10× can not only make the whole model an image, but also make an image only contain a few pores, or even only a part of a hole, so that Both micro and macro targets are imaged and accurately measured.

[0052] Camera 4, Panasonic WV-CP410 / G type, the camera sensitivity is 3LUX, the horizontal...

Abstract

A quantitative processing device and method for the dynamic color image of microscopic oil displacing is disclosed. Different kinds of oil displacing experiments can be implemented by microscopic network model for precisely describing the displacing tracing and rule and quickly calculating out the residual oil reservoir in order to determine the injection amount and crude oil output. Its hardware is composed of microdisplacing pump, microscopic simulating model, microscope, color camera, color image memory card and decoder, multifunctional card, computer, monitor and color ink-jet printer. Its software consists of dynamic color image processing software, static color image processing software and universal color image processing software.

Description

technical field [0001] The invention belongs to the technical field of oil field development experiments, and in particular relates to a microcosmic oil displacement dynamic color image quantitative processing device and processing method. Background technique [0002] The indoor oil displacement simulation experiment technology using the micro network model has been widely used at home and abroad, but the acquisition and analysis of the experimental data in the past only stayed at the means of taking pictures and photographs, and could only be described qualitatively. How to improve the quality of experimental data and how to improve the analysis and processing methods of data is a subject that petroleum experiment workers have been concerned about and actively carried out for many years. Image analysis technology is an effective means to improve the analysis accuracy of microscopic seepage experimental data. Through this technology, It can make the analysis of experimental...
