Abstract
The utility model relates to a pressure tapping connector for oil deposit flow simulation experiment. The technical scheme is as follows: the pressure tapping connector mainly consists of a pressure taping opening, filter meshes, great-diameter coarse sands, a filter mesh external pressure bracket, a filter mesh internal bracket and a pressure tapping connector cylinder. Both ends of the pressure tapping connector cylinder are connected with a model pipe, cross-linked polymer enters the model pipe through the model pipe entrance to flow and flows out from an outlet pipe, the pressure of the cross-linked polymer can be measured at a plurality of measuring points, both sides of each measuring point are respectively provided with the filter meshes, the great-diameter coarse sands are filled in the filter meshes, and both sides of the filter meshes are respectively provided with the filter mesh external pressure bracket and the filter mesh internal bracket. The connector has the following advantages: the communication property of the viscous fluid in porous media is good due to large space between the coarse sands; pressure transferring is accurate; the blockage at the side pressure holes at the pressure measuring point by the viscous cross-linked polymer, which can cause blockage to the flow or side pressure hole, can be avoided; thus avoiding the occurrence that the tapped pressure does not confirm to the pressure of the cavity inner cavity or that the pressure can not be tapped.
Description
One, technical field:
The utility model relates to a kind of laboratory apparatus, particularly a kind of oil reservoir flow simulating experiment pressure joint.
Two, background technology:
Improving recovery efficiency technique research is one of hot fields of petroleum works area research.At present, increase swept volumes to improve recovery ratios are increasingly mature tertiary oil recovery technologies thereby annotate viscous fluids such as cross-linked polymer or polymer, experimental study is one of means of using always of people.In the simulated experiment in order to obtain experimental data, need be at the different parts pressure gaging pressure of model, and original pressure joint below model pipe or the side be provided with a plurality of pressure taps, so that the polymer in the measurement cylindrical shell or the flow differential pressure of cross-linked polymer etc., because the rock core sand grains diameter little (generally at 40～180 orders) in the model pipe, the viscosity of cross-linked polymer is high and thicker, stop up pressure tap easily, make the pressure of the pressure of taking-up and cylinder lumen locality inconsistent or just can not get pressure at all, easily cause the simulated experiment data inaccurate, or the failure of an experiment.
Three, summary of the invention:
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of oil reservoir flow simulating experiment pressure joint that can accurately measure pressure reduction is provided.
Its technical scheme is: mainly be made up of toward external pressure frame, screen pack inner support and pressure joint cylindrical shell pressure tappings, screen pack, big particle diameter coarse sand, filtration, the two ends link model pipe of pressure joint cylindrical shell, cross-linked polymer enters model pipe from the model pipe inlet and flows, and flow out from outlet, by a plurality of pressure taps cross-linked polymer is carried out pressure measurement, the both sides of described each pressure tap are respectively equipped with screen pack, be filled with big particle diameter coarse sand in the screen pack, the both sides of screen pack are respectively equipped with screen pack external pressure frame and screen pack inner support.
The beneficial effects of the utility model are: because hole is big between the coarse sand, viscous fluid connectedness in the porous media is good, transmission pressure is accurate, make the side pressure hole at pressure tap place avoid being stopped up by the cross-linked polymer of thickness, cause and flow smooth or stop up pressure tap, thereby avoid the situation that the pressure of the pressure that takes out and cylinder lumen is inconsistent or just can not get pressure at all.
