• understand correlative relationships at the basin or field scale

• 识别古生态重建中使用的元素代理

• 帮助建设序列地层框架

• identify physical properties of rocks for drilling and compilations

Bruker为核心和切割的元素和化学分析提供了工具，以使Chemostraphy容易和可扩展。点击下方了解更多有关将ChemostraTigraph对任何大小项目应用的更多信息。

Elemental Analysis is an important tool for the field and petroleum geologist to characterize and identify petroleum- or gas-bearing formations. Drill cuttings, mud, or cores can be analyzed by X-ray Fluorescence (XRF).

Additional information on the mineralogical composition of the sediment or formation is offered by X-ray Diffraction (XRD). XRD distinguishes minerals that have the same or similar chemistry by their crystal structures. It not only allows the identification of minerals withdiffrac.eva.，还提供了使用RIETVELD方法提供的无标准量化。甚至可以使用该方法量化均匀的非结晶相。它使得能够针对潜在的储层和主机形成。主要优点是相当简单且快速的样品制备。钻头切割的分析可以在使用Bruker的Benchtop中的移动实验室完成D2 PHASER。在实验室设置中D8 ENDEAVOR或者D8推进是最佳选择。

Understanding porosity and permeability is important for oil and gas reservoir characterization, sedimentology, hydrogeology and groundwater studies. XRM enables characterization and visualization of pores, pore size distribution, and of open versus closed pore networks. This information can have profound implications on oil and gas production models, gas or water flooding, analog studies, contaminate flow modeling, deformation experiments and sedimentary petrology.

这analysis of shale reactivity typically involves a variety of analytical techniques, including but not limited to X-ray diffraction, X-ray fluorescence, gamma logging, optical microscopy, electron microscopy, total organic content, and cation exchange capacity. From a mineralogical perspective, XRD is widely considered to be the favored technique, particularly for discrimination between elementally similar phases.

For example, hematite (Fe2O3) and siderite (FeCO3) give similar elemental signatures but distinct diffraction patterns. Diffraction data are often obtained for both vertical and horizontal segments of wellbores. Analysis of the vertical section allows for the identification of zones with desirable physical properties. In horizontal segments of unconventional reservoirs, XRD is primarily used in geosteering, to ensure that the wellbore stays within a specific geological bed.
