Abstract: A substance component detection apparatus and a method are provided to reduce absorption of an infrared signal by a window medium, thereby obtaining abundant fingerprint region signals. The apparatus includes: a sample pool, an infrared optical window, an infrared light source, and a detector. The infrared optical window has a first surface that faces an inner side of the sample pool and that is configured to be in contact with a to-be-detected substance, and a second surface exposed on an outer side of the sample pool. A protruding portion is formed between two adjacent grooves on the second surface, and any protruding portion has an incident surface and an emergent surface. An infrared signal emitted by the infrared light source is irradiated on the incident surface. The detector determines a component of the to-be-detected substance and/or content of the component.

Abstract: Drug eluting stents, methods of making, using, and verifying long-term stability of the drug eluting stents, and methods for predicting long term stent efficacy and patient safety after implantation of a drug eluting stent are disclosured. In one embodiment, a drug eluting stent may include a stent framework; a drug-containing layer; a drug embedded in the drug-containing layer; and a biocompatible base layer disposed over the stent framework and supporting the drug-containing layer. The drug-containing layer may have an uneven coating thickness. In addition or in alternative, the drug-containing layer may be configured to significantly dissolve/dissipate, disappear between 45 days and 60 days after stent implantation. Stents may reduce, minimize, or eliminate patient risks associated with the implantation of a stent, including, for example, restenosis, thrombosis, and or MACE.

Abstract: A method for creating branch fractures in an oil well, including: injecting a first pad fluid containing a first absorbent resin to a first position of the main fracture; injecting a second pad fluid containing a second absorbent resin to a second position of the main fracture; after the second absorbent resin absorbs water and expands to form a first plugging layer, injecting a third pad fluid free of absorbent resin to the main fracture to build up a pressure at the first plugging layer; exerting the pressure to sides of the main fracture to form a first branch fracture; breaking the first plugging layer to generate a fragment; bridging the fragment to the first absorbent resin to form a second plugging layer; and injecting a third pad fluid to build up a pressure to form a second branch fracture at the first position.

Abstract: A method for creating a branch fracture with temporary plugging and pressure buildup using super absorbent resin, comprising: setting a fracturing packer to fracture a target layer by pad fluid to form a main fracture; injecting into the main fracture pad fluid mixed with salt-intolerant super absorbent resin and performing replacement till depth of the main fracture, and then injecting pad fluid mixed with strong salt-tolerant super absorbent resin; after the strong salt-tolerant super absorbent resin absorbs water and expands to form a temporary plugging layer, re-injecting the pad fluid to create a branch fracture with pressure buildup; and lifting injection pressure to break up the temporary plugging layer formed by the strong salt-tolerant super absorbent resin to form residue, transporting the residue to the depth of the main fracture to bridge the temporary plugging layer formed, and re-building up pressure to create a branch fracture.

Abstract: The present invention provides a method for further forming a plurality of small fractures in a main fracture. If a radial main fracture is further fractured axially to form a plurality of branch fractures, the stimulated volume of the oil and gas reservoir will be achieved to greatly increase the yield of dense oil and gas. The main contribution of the present invention is to form three-dimensional fracture networks for any low-permeability oil reservoirs to achieve stimulated reservoir volume. The concept is that an original main fracture is further fractured to form a plurality of branch fractures (the branch fractures form included angles with the original main fracture), and the locations for forming the branch fractures in the main fracture and even the size and length of the branch fractures can be controlled artificially, so that the branch fractures can be formed by fracturing where needed.
