对操作，钻探和完成的编队评估

Cuttings provide a valuable direct measurement of rock where physical and chemical properties can be directly assessed. Cuttings provide a cost-effective alternative and supplement to high-resolution核心上的化学地层学by providing:

• 成本效益的实时直接测量地层
• 水平和垂直井的数据
• 保留有机物
• No down-hole operational risk

On-site elemental data can revolutionize a drilling program. Wellsite X-ray Fluorescence (XRF) analysis programs are easy to implement into any standard mudlogging workflow. Cleaned and dried cuttings can be easily prepared in sample cups or pressed pellets to provide laboratory-quality geochemical analysis in near real-time. This data can be used for:

• Landing a well with confidence by identifying geochemical markers
• Additional information for Geosteering and a backup technology in the event of a MWD or LWD failure
• Identifying downhole lithology with confidence as a verification to wireline and MWD
• Identifying metal in cuttings to determine if it is from the bit, casing, whip stock or surface equipment
• 构建本地或区域化学地层学模型，可在井之间提供更准确的相关性
• 提供裂缝设计的其他信息
• 改善未来的健康计划

Mineral data at the well-site has been sought-after to aid in formation evaluation, completions design and to de-risk wells. It has been well established that poor stage performance has been linked to properties like rock type and pre-existing fractures. The addition of on-site mineral identification can give operations geologists and petroleum engineers near real-time data for robust scientific decision making that reduces costs and increases performance. For example, Bruker's automated mineralogy solution友善leverages technologies that can be deployed on-site or in forward field labs to collect mineral data from cuttings. All Bruker’s solutions are easy to set up, can be run by a technician with remote data reduction, and run off standard rig power.

Elemental and mineral data is most useful as part of a comprehensive formation evaluation program. Well-site mineral and geochemical data can be incorporated into reservoir and petroleum system models as tools for all aspects of the exploration and development process. For example:

• 可以将散装和模态矿物信息纳入储层质量评估，并确定有问题的区域（例如肿胀粘土）
• 纹理分析和岩性型可以将岩层划分为易于理解并纳入完整设计和良好计划的岩性。
• Aid in sequence stratigraphic interpolations and well-to-well correlations
• 出处分析包括识别和映射数据矿物
• 计算岩石地质力学和物理特性，包括杨的模量，润湿性，硬度
• Direct analysis of porosity, compaction, kerogen, texture, grain size, grain shape, grain composition and diagenesis

粘土矿物包括大量矿物风化产生的大颗粒，分层的硅酸盐。由于它们对周围地质地层的物理特性，粘土对于采矿和钻探行业特别感兴趣。在这里，我们通过X射线衍射（XRD）与D2 Phaser Bachtop衍射仪讨论粘土的定性分析，特别是针对识别肿胀的粘土物种。在许多钻井应用中，粘土矿物是关键问题。例如，在液压压裂工业中，高浓度的粘土表明延展性更高，可能导致骨折的形成不良。此外，肿胀粘土的存在可能导致在启动过程中水引起的水肿胀或在生产阶段的负面影响（例如自我修复）。这些矿物质的识别对于开发添加剂和稳定剂的量身定制溶液至关重要。
