38 results about "Horizontal migration" patented technology

A cup-shaped receptacle designed to engage the neck of a bottle and rigidly support it in a near horizontal position. The receptacle can be incorporated into many common building materials, so an array of the receptacles permits an attractive display of bottles. Bottles are held in place through the force of gravity and by resilient rings or gaskets disposed in the interior of the receptacle that limit vertical and horizontal migration of bottles. The rings also protect foil caps from damage.

A fracturing fluid containing proppant particles is injected into a fracture made in a low-permeability subterranean formation, providing a turbulent flow of the fluid in the fracture during injection. This allow to increase a fracture conductivity after its closure by means of preventing transverse migration of proppant particles within the fracture and the reduction of their setting rate.

A horizontal ion migration spectrum, including two parallel panels, defined a container between the two parallel plates.Analyst ions passed through the container along the entrance to the outlet.RF constraints guide ions along the axis.Establish an analysis airflow that is orthodox with the axis.The DC electrostatic analysis field is opposite to the direction of the analysis of the airflow, so that the "tension" of the analysis of the ion of the selected migration rate can be balanced by the electrostatic analysis field on the ion.Therefore, the selected pyramids can reach the exit of the analyzer of the horizontal migration analyzer along the stable path.However, the force on the ionic ion that works in non -selected migration is unbalanced, and these ions will be deviated and lost.

The invention discloses a composite barrier for preventing horizontal diffusion and migration of underground water layer pollutants and application thereof. The composite barrier is formed by encapsulating expansion clay by a water-soluble polymer film. During the application, the composite barrier is placed into a vertical open groove with a watertight layer arranged at the groove bottom, the filling height of the composite barrier in the vertical open groove is not lower than the upper plane of the underground water layer, wall protecting slurry is removed, and then, soil is filled back into the vertical groove until the vertical groove is flatly filled. The composite barrier has the advantages that the construction is simple, the engineering manufacturing cost is low, the anti-seeping effect is good, and the like. The horizontal migration of pollutants in the underground water layer can be better prevented.

The invention discloses a fracturing and sanding design method based on a large-scale parallel plate proppant migration and laying physical model experiment, and specifically relates to the field of oil and gas field development. This method determines the value range of each construction parameter according to the fracturing target, and uses a large-scale parallel plate proppant migration and laying phantom experimental device to conduct a control experiment on each construction parameter to obtain the migration of proppant under different parameters and the final sand embankment. Morphological pictures, and use sand embankment shape evaluation parameters to quantitatively evaluate the final sand embankment shape, optimize construction parameters, measure the horizontal migration velocity and vertical settlement velocity of proppant under different conditions, and calculate the propping height and horizontal propping fracture length, After checking, determine the sanding parameters of each stage of fracturing, and combine the ratio of proppant to fracturing fluid at each stage to determine the final fracturing sanding construction plan. The invention solves the problem of few and incomplete quantitative evaluation parameters of experimental results, greatly improves the effect of fracturing and increasing production, and effectively reduces the cost of fracturing construction.
