Abstract: | Laser Confocal Scanning Microscope analysis is a new technique for 3D micro-features of inclusions in rocks and minerals. It has many strong points that normal optics microscope and scan electron microscope do not have, such as simple sample making, layered scanning, 3D image reconstruct, clearly differentiate configuration and component between organism and mineral. Because of the technique having been used in the reservoir study in the exploration area of Daqing, we have reconstructed the 3D structure of reservoir pore and microcrack. After we have studied the distribution of organism in source rock and crude oil in reservoir, we found that crude oil form has important meaning to the study of watered-out sand. We also studied the character and the stage of secondary inclusion in fracture. Furthermore this method has been used in the study of Paleozoic microfossil, we have discovered spore fossil which has never be seen in the exploration area of Daqing. In the study of the mechanism of crude oil emulsification, we used the confocal technique to see the inner configuration of emulsified oil for the first time, by the dynamic analysis we can confirm its stabilities, this afford the scientific gist in the study of the mechanism of crude oil emulsification. The Laser Confocal Scanning Microscope analysis has made the unheard-of effect in the study of reservoir analysis in the exploration area of Daqing. |
