摘要(Abstract)：
传统的碳氧比能谱测井仪器虽然具有较好的稳定性和重复性,但存在纵向分辨率低和受环境因素影响大的缺点。为了解决薄、差层的剩余油评价问题,在大庆油田杏树岗地区采用了纵向分辨率相对较高的伴随粒子碳氧比能谱测井仪。通过伴随粒子碳氧比能谱测井仪器的原理研究及初步应用,阐述了该仪器在薄层剩余油测井中的优越性,指出伴随粒子碳氧比能谱测井仪能够进行地层的选择性测量,可以去除井眼、流体等影响,其纵向分辨率达到0.4m,是在薄、差层中寻找剩余油的有效手段。杏树岗地区6口生产井的实际测量及其水淹层解释结果也说明,该仪器的解释精度高,投产效果好,实现了在油田开采后期提高薄、差储层产油量、降低含水率的目的,显示出广阔的应用前景。
Though the traditional carbon/oxygen spectrometry logging tool has good stability and repetitiveness, it's resolution is poor and easily effected by environmental factors. In order to solve this question, the new associated particle carbon/oxygen spectrometry logging tool which has higher resolution was used in Xing-shugang region of Daqing oilfield. The new spectrometry tool is advantaged to evaluate thin-bed reservoir by the principle' s research and its initial application, which can measure the information from the specific region of the formation and the influence of borehole, casing, cement can be entirely eliminated. Measured by the new tool is an effective method to find residual oil in thin-bed reservoir because of the high resolution of 0. 4 meter. High precision and good impact were showed by using the tool and the result of flooded strata interpretation in 6 production wells in Xingshugang region. Therefore, increasing oil output and reducing water output have been realized, which showed that there is a good market in finding the residual oil in thin-bed reservoir oilfield during the latter stage of high water cut.
