中国同位素中子源测井技术与应用进展

摘要

同位素中子源测井技术是以同位素中子源产生的中子与井眼和地层物质元素原子核发生作用,通过探测中子或伽马射线,从而进行孔隙度、含油饱和度和元素含量等地质和工程参数确定的测井技术.本文概述了同位素中子源测井技术,回顾了我国同位素中子源测井技术的发展历程、技术现状及应用,并展望了同位素中子源测井技术的发展前景.%Isotopic neutron source well logging is a technology, through wich the geological and project parameters of porosity, oil saturation and element content can be determined by recording neutron or gamma ray, which are produced through the reaction of neutron generated by isotopic neutron source with nuclei in borehole and formation material. Isotopic neutron source well logging technology was sketched out, the development course, technical aspect and application of isotopic neutron source well logging were summarized and the development prospect of isotopic neutron source well logging was looked ahead.
