The utility model is characterized in that both ends of a main body (1) are respectively connected with an end cover (2) and a valve (3); a control valve (5) which is communicated with a vacuum pump (4) is fixed on the end cover (2); a filter is arranged between the main body (1) and the end cover (2); oil sand infiltration layers (7) with different granularity are arranged in the main body (1) according to the anisotropy of actual oil reservoirs. The oil reservoir simulation device, which can really reflect the pore structural characteristics, the surface properties and the anisotropy of actual oil reservoirs, can be used for physical simulation research work of oil reservoirs in which high infiltration layers or specially high infiltration layers exist because of loose cementation or long-term erosion by injected water.
Description
Technical field:
The utility model relates to device, the especially reservoir simulator that is used for evaluating chemical additive performance parameter in the oil recovery field, oil field.
Background technology:
In oilfield development process, chemical assistant has a very important role for improving oil recovery factor, the chemical assistant product that possesses certain function often has a lot, and this just need estimate properties of product, therefrom filters out performance and the highest product of price ratio.Chemical assistant use to as if oil reservoir because the oil reservoir its own particularity, the work of chemical assistant performance evaluation is difficult to carry out on actual oil reservoir, can only finish on synthetic core usually.
At present, the synthetic core that is used for appraisal is to be formed by silica sand and epoxy resin compacting, and wherein epoxy resin is cementing matter, and silica sand is skeleton.Epoxy resin is compared with natural core cementing matter such as clay and carbonate etc., exist than big-difference at aspects such as chemisorption characteristics between them, carry out the test of chemical assistant adsorbance on synthetic core, its test result is difficult to reflect the truth of natural core adsorbance.In addition, relatively loose or wash away the oil reservoir that has most permeable zone or extra-high-speed pervious course for a long time for those gluings because of injecting water, adopt the silica sand and the rock core of epoxy resin pressing acquisition to be difficult to reach factor of porosity and permeability index request.
The utility model content:
In order to overcome the deficiency that existing synthetic core is difficult to reflect the truth of natural core adsorbance, the utility model provides a kind of reservoir simulator, this reservoir simulator can reflect actual reservoir pore architectural feature, surface nature and nonuniformity more truly, and it is relatively loose or wash away the PHYSICAL MODELING OF IN work that has most permeable zone or extra-high-speed pervious course oil reservoir for a long time because of injecting water to be used for those gluings.
The technical solution of the utility model is: this reservoir simulator comprises main body, and the two ends of main body connect end cap and valve respectively, and the fixing operation valve that communicates with vacuum pump is equipped with filtrator on the end cap between main body and end cap; According to actual oil reservoir nonuniformity varigrained oil-sand pervious course is housed in the main body.
Above-mentioned main body is square tube shape or cylindrical shape; Main body is connected by flange, sealing gasket and bolt with end cap and valve; The oil-sand pervious course is 3 layers.
The utlity model has following beneficial effect: owing to take such scheme, according to simulating oil deposit permeability, factor of porosity, physical dimension and heterogeneous body situation, form by the size of adjusting natural oil-sand particle, load onto different oil-sand pervious courses in device inside, from aspects such as physical dimension and physical parameters actual oil reservoir is simulated, can realize evaluation and injection parameter optimal design the oilfield chemical auxiliary performance; Because the oil-sand pervious course of filling in the main body does not contain cementing matter, oil-sand can be removed after the experiment, reused, not only reduce cost but also free from environmental pollution, utilize this device to use natural oil-sand as medium, can simulate its distribution in actual oil reservoir easily, the chemical assistant parameter of being obtained in the experiment is true and reliable.Can reflect actual reservoir pore architectural feature, surface nature and nonuniformity more truly, it is relatively loose or wash away the PHYSICAL MODELING OF IN work that has most permeable zone or extra-high-speed pervious course oil reservoir for a long time because of injecting water to be used for those gluings.
