项目摘要
9360215 Bayless The measurement of bulk density as a function of position in boreholes is of major importance for determining the characteristics of geological formations. The best approach for measuring bulk density involves the scattering of high energy photons in the formation by Compton processes. However, only radioactive gamma ray sources are currently available for use in both measurement while drilling (MWD) and wireline density instruments. These involve substantial concerns with safety and environmental contamination. We propose to perform the research necessary to develop an x ray source, termed the Double ended X ray Tube (DXT), for MWD applications. This novel, compact source is expected to offer absolute safety and improved measurement accuracy in the highly stressing MWD environment. The overall objective of Phase I is to demonstrate the technical feasibility of the DXT concept. This will be accomplished by performing three tasks: (1) design and assemble a DXT experiment for operation at high voltage; (2) perform tests to evaluate and demonstrate the DXT operating characteristics with the goal and (3) develop the conceptual design for a low cost DXT system for MWD applications. A leading MWD logging company will participate in Task 3 and provide an overall technical review of the project. If successful, the Phase I results will form a firm foundation for the development and demonstration of a laboratory prototype DXT system in Phase II.
小行星9360215 作为钻孔中位置的函数的体积密度的测量对于确定地质构造的特性是非常重要的。 测量体积密度的最佳方法涉及康普顿过程对地层中高能光子的散射。 然而,目前只有放射性伽马射线源可用于随钻测量(MWD)和电缆密度仪器。 这些涉及安全和环境污染的重大问题。 我们建议进行必要的研究,以开发一种X射线源,称为双端X射线管(DXT),随钻测量应用。 这种新颖、紧凑的光源有望在高应力随钻测量环境中提供绝对的安全性和更高的测量精度。 第一阶段的总体目标是证明DXT概念的技术可行性。 这将通过执行三项任务来实现: (1)设计并组装DXT高压运行实验;(2)执行测试,以评估和演示DXT的运行特性,并实现目标;(3)开发用于MWD应用的低成本DXT系统的概念设计。 一家领先的MWD测井公司将参与任务3,并提供项目的总体技术审查。 如果成功的话,第一阶段的结果将为第二阶段的实验室原型DXT系统的开发和演示奠定坚实的基础。
