Description
Technical field
The utility model relates to a kind of experimental provision, particularly a kind of novel imbibition experimental provision of the application of chemical experiment field.
Background technology
In recent years, day by day to increase and conventional gas and oil resource workable reserve successively decreases year by year along with energy demand, the energy position of unconventional petroleum resources is important all the more, and wherein the exploitation of low permeability oil field has received the great attention of oil field scientific worker.Low permeability oil field is less due to reservoir core pore throat radius, there is stronger capillary force, so recover the oil by imbibition improve low permeability oil field oil recovery factor further.Usual field practice needs Related Experimental Study to provide fundamental basis, and is optimized extremely is necessary so carry out indoor imbibition oil recovery experimental study parameters.Porous medium spontaneous imbibition oil recovery research method is mainly volumetric method and mass method two kinds, and wherein mass method is because laboratory automation degree is high and reason easy to operate is widely used in current imbibition research.But also there is certain defect in mass method at present: in (1) imbibition process, the change of core quality difference is little, is subject to extraneous factors impact (slight perturbations just can bring larger reading error) such as vibrations, air and water vapor; 2. can not enter imbibition liquid by desorption completely from the inner imbibition of rock core to appearance crude oil, part be attached to core surface, and it produces viscous force can affect core quality measuring accuracy.
Summary of the invention
Technical problem to be solved in the utility model be overcome solution gas in the imbibition liquid that exists in background technology, gas is got rid of in rock core inside and core surface attaching oil affects the problem of imbibition oil pump capacity computational solution precision, and a kind of novel imbibition experimental provision is provided, this novel imbibition experimental provision, by stirring imbibition liquid in experimentation in good time, get rid of the bubble and the oil droplet that are attached to core surface, imbibition experimental precision can be improved.
The invention for solving the technical problem reaches by following technical scheme: this novel imbibition experimental provision comprises closed box, electronic balance and imbibition cup, in the middle part of described closed box, dividing plate is set, described dividing plate is equipped with electronic balance, and electronic balance connects rock core by connecting link; Closed box inner bottom part is equipped with imbibition cup, described imbibition cup inner bottom part center is equipped with paddle, paddle top imbibition cup inner bottom part both sides are fixedly connected with fixed support, fixed support passes perpendicularly through imbibition cup sidewall by body of bolt and is connected on imbibition cup, grips rock core in the middle part of described two fixed supports.
The utility model can have following beneficial effect compared with above-mentioned background technology: this novel imbibition experimental provision, and owing to adopting said structure, imbibition cup heat effect can meet different experiments temperature requirement; Paddle can drive imbibition liquid to flow, and makes to enter imbibition liquid smoothly from rock core internal penetration to the oil droplet of outside in imbibition experimentation, eliminates it and is adsorbed on rock core appearance and tests the impact brought to core quality, finally reaches and improves experimental precision object.Computer acquisition system gathers different experiments moment electronic balance registration automatically, alleviates experimenter's working strength.In experimentation, stir imbibition liquid in good time, get rid of the bubble and the oil droplet that are attached to core surface, and then improve imbibition experimental precision.
