摘要

利用X射线源替代密度测井中的

137

Cs放射源成为石油测井发展的新趋势。为探究在密度测井中使用较低能量的X射线源替代

137

Cs放射源后的近源距变化，利用蒙特卡罗模拟方法，研究了不同能量X射线源在不同孔隙石灰岩含水地层中所对应的零源距位置，另外根据不同源对应的密度响应灵敏度，分析了近源距区间。研究表明：能量较低的X射线源相比于

137

Cs放射源密度仪器对应的零源距较小，两者密度灵敏度相同时，X射线源的近源距区间更短。

Abstract

Background

It has become a new trend to use X-ray source instead of

137

Cs source in density logging for development of oil logging.

Purpose

This study aims to analyze the near detector-source spacing's change when using a lower energy X-ray source instead of

137

Cs source in density logging.

Methods

Monte Carlo simulation method is used to study the critical detector-source spacing of different energy X-ray sources during the formation of water saturated limestone with different porosity

in addition

the near detector-source spacing is analyzed according to those sensitivities of X-ray sources and

137

Cs source.

Results

Simulation results show that low energy X-ray source's critical detector-source spacing is shorter compared with

137

Cs source's density instrument. When the density sensitivity is the same

the near detector-source spacing of X-ray source is shorter than that of

137

Cs source.

Conclusion

This study provides a theoretical basis for the design of near detector-source spacing of instrument.
