摘要： 应用同步辐射X 射线荧光微探针(SRXRF) 无损分析技术,对准噶尔盆地中部Ⅰ区块两口井侏罗系储集层砂岩中与含油包裹体共生的盐水包裹体进行了微区分析。结果表明,庄1 井和征1 井的包裹体样品同步辐射X 射线能谱图各元素净峰面积存在一定差别,通过标样对K、Ti、Mn、Fe、Ni、Cu、Sr 等元素含量进行了标定,除Fe 含量变化大外,其他元素含量都有较大差别,认为庄1 井和征1 井成藏流体性质差别较大,推测庄1 井与征1 井侏罗系油藏具有不同的成藏史,其油源也是有差别的。这也得到了流体包裹体均一化温度和全岩含油包裹体成分分析的佐证。

Abstract: The saline inclusions in the authigenic minerals of sandstone reservoirs of Jurassic from two wells in Block-1 of center Junggar basin are measured by synchrotron radiation X-ray microprobe techniques. Some element contents, such as K, Ti, Mn, Fe, Ni, Cu and Sr, are calibrated by NIST SRM 612 typical sample. The results show that the microelement contents (except for Fe) of saline inclusions of Well Zhuang-1 and Well Zheng-1 are distinctly different. It is predicted that the reservoirs of Jurassic in Well Zhuang-1 and Well Zheng-1 are different in hydrocarbon accumulation and oil source, for their fluid properties are in big difference. The analysis of the homogenization temperature and the oil-bearing fluid inclusions of whole core confirm the conclusion above.

Key words: Junggar basin, saline inclusion, microelement, homogenization temperature
