激光共聚焦扫描显微检测技术在大庆探区储层分析研究中的新进展

激光共聚焦扫描显微镜（Laser Confocal Scanning Microscope）分析技术是20世纪80年代末、90年代初兴起的一项新的光学显微测试方法，它具有普通光学显微镜和扫描电子显微镜不具备的很多优点，如样品制备十分简单、分层扫描和三维立体图像重建、清晰分辨有机和无机质等。我们将该技术应用到大庆探区的储层研究中，进行了储层孔隙和微裂缝的三维结构重建，对储层中原油形态进行了详细研究，其中原油形态观察对薄差水淹层的研究有重要意义，研究了裂缝中次生包裹体特征及形成期次，此外，该方法应用于微体古生物化石研究在大庆探区发现了以前本区未见的孢子化石种类。在原油乳化机理研究方面，首次应用共聚焦观察了乳化油的内部结构，通过动态分析可以确定其稳定性，这为乳化油乳化机理研究提供了科学可靠的依据。激光扫描共聚焦显微检测技术在大庆探区储层分析研究中取得了前所未有的效果。

New progress of Reservoir research by the technology of Laser Confocal Scanning Microscope analysis in The Daqing exploration area

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.
