原油含水测定及化验分析方法的研究

Research on Determination of Water Content in Crude Oil and Its Analytical Method

准确测量进口原油中明水以及测定原油中含水率是实现原油公平计量、交接的基本依据。而且,含水率会影响原油中的盐含量,进而影响原油物性品质,高含盐原油会与某些炼化企业装置不兼容。同时,在油田企业与管道企业交接或者管道企业与炼化企业交接时,含水率也是各方关注的焦点,由于采取的方法不妥以及设备条件的限制或人为因素的影响,极易使原油含水率测量的准确度降低。本文根据现有的原油含水测定以及化验分析计量技术,查找影响原油含水测定化验的不利因素,为含水测定提供了理论、技术、实践指导。

Accurate measurement of open water in imported crude oil and determination of water content in crude oil are the basic basis for realizing fair measurement and connection of crude oil. Moreover,the water content affects the salt content in crude oil,and then affects the physical quality of crude oil. Crude oil with high salt content will be incompatible with some equipments of refinery enterprises. At the same time,water content is also the focus of attention when enterprises of oil field join pipeline enterprises or pipeline enterprises join refinery enterprises. Due to improper methods,equipment conditions or human factors,it is easy to reduce the measurement accuracy of water content in crude oil. In this paper,according to the existing determination,analysis and measurement technology of water content in crude oil,the unfavorable factors affecting water content determination of crude oil are found,which provides theoretical,technical and practical guidance for water content determination.
