Title: Method for classifying deep rock geofacies based on data mining
Inventor: TIAN FEI
IPC: G06Q50/02
Filed: 2017-12-29
Abstract: Abstract Guided by existing geological knowledge, rock type classification is implemented for complex geological features of deep rock in a target area to obtain a rock type classification scheme 1; the rock types that cannot be distinguished by using logging information are merged by adopting a logging response radar plot to obtain a rock type classification scheme 2; sensitive logging parameters are selected for establishing a cross plot, new electrofacies are obtained by adopting a data mining method, and a geofacies Classification scheme and classification standard is established in view of actual needs of deep oil and gas reservoir evaluation. The method for dividing deep rock geofacies based on geological knowledge and logging data mining can be used in the application environments of different geological conditions and different depths, and is particularly suitable for solving underground deep rock type classification problems.
Patent AU-2019202213-B1 (AU)
Title: An inspection apparatus for crystal jewelry
Inventor: Fan Kuanjiang
IPC: G01N21/87
Filed: 2019-03-29
Abstract: This invention discloses an inspection apparatus for crystal jewelry, including an inspection 
rod 11, wherein an observation cavity 12 is arranged in the inspection rod 11 with an opening 
to a first side, wherein a handle 19 is fixedly connected with a bottom end surface of the 
observation cavity 12, and a bottom end inner wall of the observation cavity 12 is provided 
with a switching device 901, and an inner wall of a second side of the observation cavity 12 
is provided with an open groove 47 mounted on a top end of the switching device 901, and an 
optical concentrating device 902 slidably connected with the open groove 47 is arranged in 
the observation cavity 12. This apparatus is simple in structure, which can be observed 
rorarably under the concentrating lighting to do an adequate inspection of the interior and 
external quality of the crystal jewelry.
