  • Patent number: 11921099
    Abstract: A method for quantitatively analyzing the reservoir formation of an ultra-deep evaporite-dolomite paragenesis system is performed as follows. A typical drilling core containing the evaporite-dolomite paragenesis system and a field section are observed. The logging data is subjected to single-factor analysis to determine the planar distribution regularity of the ultra-deep evaporite and the dolomite, and the analysis of sedimentary combination pattern and development evolution regularity is performed. The diagenetic system is determined, and the reservoir formation of the evaporite-dolomite paragenesis system is analyzed. Based on the above technical solutions, the property, the evolution path and the reservoir formation of sedimentation-diagenesis fluids in the evaporite-dolomite paragenesis system can be clarified.

  • Patent number: 9443902
    Abstract: A fabricating method of a back-illuminated image sensor includes the following steps. First, a silicon wafer having a first surface and a second surface is provided, wherein a number of trench isolations are formed in the first surface, and at least one image sensing member is formed between the trench isolations. Then, a first chemical mechanical polishing (CMP) process is performed to the second surface using the trench isolations as a polishing stop layer to thin the silicon wafer. Because the polishing rate of the silicon material in the silicon wafer is different with that of the isolation material of the trench isolations in the first CMP process, at least one dishing depression is formed in the second surface of the silicon wafer. Finally, a microlens is formed above the dishing depression, and a surface of the microlens facing the dishing depression is a curved surface.
