SBIR Phase II: X-Ray Instrument for Formation Bulk Density Determinations MWD Applications

小行星9500680 这个小型企业创新研究第二阶段项目提供了消除目前在随钻测量（MWD）密度测井工具中使用的放射性物质的机会。 现有的工具为大多数地层评价提供了关键信息，但对环境以及操作和运输这些工具的人员构成了风险。 该项目的总体目标是进行所需的研究，以开发一种新型的电子X射线仪器，用于测量随钻测量应用中的松散地层密度和岩性（成分）。 该项目的具体技术目标是：（1）改进第一阶段设备，以实验方式证明高能电子束的可靠操作;（2）改进X射线密度/岩性测井仪的基本几何结构，以最大限度地提高其性能;（3）设计和建造高能实验室原型X射线测井仪;（4）测量实验室原型X射线系统的性能特征;以及（5）实验评估高能MWD 模拟地层中的X射线工具。 Sperry-Sun钻井服务公司是随钻测量领域的领导者，也是第一阶段的贡献者，将参与目标2、3和5。 如果成功，该项目将提供一种新型的MWD密度/岩性测井工具，其性能参数与放射性工具相当或超过放射性工具。 然而，它将消除与现有工具中的放射性材料有关的风险。 ***

9500680 Bayless This Small Business Innovative Research Phase II project provides the opportunity to eliminate the radioactive material currently used in Measurement-While-Drilling (MWD) density logging tools. The existing tools, which provide critical information for most formation evaluations, pose risks to the environment and to the personnel that operate and transport them. The overall objective of the project is to perform the research required to develop a novel electrical x-ray instrument for the measurement of bulk formation density and lithology (composition) in MWD applications. The specific technical objectives of the project are: (1) to modify the Phase I device to experimentally demonstrate reliable electron beam operation at high energies; (2) to improve the basic geometry of the x-ray density/lithology logging tool in order to maximize its performance; (3) to design and construct a high energy laboratory prototype x-ray logging tool; (4) to measure the performance characteristics of the laboratory prototype x-ray system; and (5) to experimentally evaluate the high energy MWD x-ray tool in simulated formations. Sperry-Sun Drilling Services, a leader in the MWD field and a Phase I contributor, will participate under Objectives 2, 3 and 5. If successful, this project will provide a new type of MWD density/lithology logging tool with performance parameters comparable to, or exceeding, those of radioactive tools. However, it will eliminate the risks associated with the radioactive material in existing tools. ***
