Embodiment Construction

[0022] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail in conjunction with the accompanying drawings.

[0023] like figure 1 as shown, figure 1 It is a flow chart of the method for making a large-scale microscopic simulation model of the present invention. In step 101, according to research needs, set technical indicators (high, low permeability, etc.), and make a master plate of a large-scale microscopic simulation model. Due to the advantages of glass with good chemical stability, wide range of spectral penetration, good heat insulation and insulation, and low light absorption coefficient, the base material of the large-scale microscopic simulation model is quartz glass or Pyrex 7740 glass. The process goes to step 102.

[0024] In step 102, according to the conventional processing technology of etching glass, photolithography, development an...

Abstract

The present invention provides a large-size microscopic simulation model production method, which comprises: according to the research requirement, setting the technical index, and producing the negative template of a large-size microscopic simulation model; carrying out photoetching, developing and washing on a large-size finished product chrome template by using the negative template; according to the technical index requirement, selecting an appropriate corrosion reagent, and etching the developed chrome template; carrying out primary washing on the etched chrome template, and carrying out drilling operation to produce the inlet and the outlet required by an experiment; repeatedly washing the prepared the chrome template of the large-size microscopic simulation model to ensure the cleanliness; and carrying out high temperature heating adhesion on the large-size microscopic simulation model. According to the present invention, with the method, the problem of the too small effective region of the model in the current microscopic simulation experiment is solved, and the research capacity of the experiment technology is substantially improved.

Description

technical field [0001] The invention relates to the technical field of oilfield development, in particular to a method for making a large-scale microcosmic simulation model. Background technique [0002] At present, there are two main types of microscopic models used in microscopic simulation oil displacement technology in the field of laboratory experiments in the petroleum industry: microscopic seepage simulation model (patent number: ZL00109777.6) and real reservoir rock microscopic pore model and its production technology (Patent No.: ZL93105170.3). Both types of microscopic simulation models are small-scale models with an effective area of ​​1.5cm 2 to 4cm 2 Among them, the application of small-scale models in microscopic simulation of oil displacement experiments has the following main problems: [0003] 1. Limited research capacity [0004] In the range of 4cm2, many experimental phenomena are not obvious, and the experimental results under the same conditions hav...
