Whether carbonate cements are under experimental conditions oily wetting characteristics in true rock core；(2) fail in latter two experimental method
Real simulation goes out carbonate cements in bead model, and then fails what clearly glossy wet carbonate cements gathered petroleum fortune
It influences；(3) before oil charging, pore throat in core sample or bead model with different wetting feature is not can guarantee
The similitude of structure, due to pore throat character and fortune poly- feature of the wetability co- controlling petroleum in interstitial space, sample
The difference of middle pore throat character will interfere the explanation of experimental result；(4) the above experimental method is not it is observed that petroleum
The poly- feature of microcosmic fortune in interstitial space, and then the distribution of glossy wet carbonate cements in interstitial space can not be specified to stone
The poly- influence of oil fortune.
As a kind of microscopic seepage experimental apparatus of high visibility, 2-D microscopic glass plate etching model is considered as seeing
Examine effective experimental provision of record petroleum fortune collecting process and carbonate cementation process.For the carbonic acid in real simulation oil and gas reservoir
Salt cement does not allow the carbonate cements in seepage experimental apparatus to occur with the flowing of fluid during petroleum fortune is poly-
Displacement.In addition, unpredictable variation occurs for wettability characteristics in experimental provision before oil charging in order to prevent, in injection experiments
Being mixed into for organic substance should be avoided in the fluid of device as far as possible.Therefore, how to utilize the method for inorganic precipitation in the microcosmic glass of 2-D
Generating strong adhesion calcite cement in glass plate etching model also becomes the difficult point of microphysics simulated experiment.
The method that calcite cement is cultivated in microscopic seepage experimental apparatus mainly includes the following three types.Method one: saturation
The calcium carbonate aqueous solution heating precipitation method, i.e., unsaturated carbonate calcium aqueous solution will be passed through in microscopic seepage experimental apparatus, at room temperature to micro-
It sees seepage experimental apparatus and carries out heating water bath, make in device that calcium carbonate aqueous solution reaches hypersaturated state and precipitated calcite is cementing
Object；Method two: equimolar concentration calcium chloride and aqueous sodium carbonate mixed precipitation method, i.e., respectively by the calcium chloride of equimolar concentration
It is filled in microscopic seepage experimental apparatus in equal volume with sodium carbonate liquor, after mixing two solution in microscopic seepage experimental apparatus
Precipitated calcite cement；Method three: ureal antigen, i.e., using urease catalyzing urea hydrolyze, make hydrolysis of urea product with
Precipitated calcite cement after calcium chloride solution mixing.The method of these three synthesis calcite cements is primarily present following ask
Topic: the settling rate of calcite cement is very slow in method one, and part calcite cement adhesion is poor, can flow with injection
The flowing of body is subjected to displacement or even is carried over seepage experimental apparatus；The settling rate of calcite cement is very fast in method two, but
It is that adhesion is very poor, is easily subjected to displacement with the flowing of injection fluid；The adhesion of calcite cement is preferable in method three,
But the organic compounds such as urea and urease are introduced in synthetic method, seepage experimental apparatus inner wall and calcite glue may be made
Knot object wettability of the surface changes, and then transports the poly- explanation influenced to petroleum to calcite cement in subsequent experimental and cause
Interference.
Therefore, it is necessary to establish one kind to etch the glossy wet carbonate cements that carry out in model to stone in microscopic glass plate
The poly- microphysics analogue experiment method influenced of oil fortune, by oily in the clear pore throat space of visual microphysics simulated experiment
The content of carbonate cements and the influence that distribution is poly- to petroleum fortune are soaked, is the content and distribution of glossy wet carbonate cements
The Influencing Mechanism research poly- to petroleum fortune lays the foundation.
