Double-tube jet flow uniform steam injection technology for horizontal well and assorted tool

ActiveCN104675373AImprove steam injection qualityUniform oil recoveryFluid removalJet flowVariable density
The invention provides a double-tube jet flow uniform steam injection technology for a horizontal well and an assorted tool. The assorted tool comprises a tubular column and a tubing nipple, and is characterized in that the tubular column is positioned at the lower end of a steam injection packer and is divided into a variable-density steam injection jet flow tube and a steam injection flushing tube; the variable-density steam injection jet flow tube and the steam injection flushing tube are connected with each other through a steam injection distributor; the variable-density steam injection jet flow tube is provided with a steam injection nozzle; a high-temperature rubber cup packer is arranged on the periphery of the variable-density steam injection jet flow tube; a high-temperature centering device is arranged between the variable-density steam injection jet flow tube and the steam injection flushing tube; and a screwed plug is arranged at the position of a port of the variable-density steam injection jet flow tube. The double-tube jet flow uniform steam injection technology replaces the original horizontal well steam injection technology, the assorted tool replaces the original tool, a range, which is 30-50 meters, of a group of steam injection points can be changed into a range, which is 15-50 centimeters, of the group of steam injection points, and the steam injection uniformity is increased by 50%, the steam using rate is increased by almost 30%, rising of edge and bottom water can be slowed down, and the recovery efficiency of an oil reservoir is improved.

Preparation method of nano silver phosphate catalyst driven by visible light

The invention belongs to the technical field of the material chemistry and particularly relates to a preparation method of a nano silver phosphate catalyst driven by visible light. According to the invention, the nano silver phosphate photocatalyst which can stably exist is prepared by a method of irradiating by different light sources and carrying out micro-injection of a reactant; and the problem that a product can be decomposed when the preparation is carried out under the condition of the visible light is avoided. Silver phosphate particles prepared by the method are of a sphere cluster structure, have the monomer diameter of 20 to 60nm and have the integral diameter of 60 to 300nm. The specification of the nano silver phosphate catalyst is far less than that of common micron silver phosphate in the market. Due to the small-size effect and the sphere cluster structure, not only is the catalytic effect of the nano photocatalyst obviously improved than that of a micron catalyst, but also the using amount of the catalyst is greatly reduced and the using cost is effectively reduced. Moreover, by changing the type of a surfactant and the light source of irradiating light in the preparation process, the controllable synthesis is implemented on nano silver phosphate with different morphologies.
