油气藏工程常用公式的单位变换

Unit Conversion of Often-used Formulas in Petroleum Reservoir Engineering

油气藏工程常用公式的单位变换,是一项重要的工作内容,它是理论研究与实际应用相结合的重要步骤。SI单位制,包括SI基础单位(SI base units)和SI矿场单位(SI field units)两部分。前者用于油气藏工程不同计算公式的理论推导,后者用于实际问题的矿场计算。因此,对于由SI基础单位表示的油气藏工程计算方法,必须进行由SI基础单位到SI矿场单位的正确变换,否则,就不可能得到正确的计算结果。本文将介绍油气藏工程中常用物理量的SI基础单位和SI矿场单位,以及它们之间的变换常数,并将重点介绍由SI基础单位表示的油气藏工程常用公式,如何变换而得到由SI矿场单位表示的相应公式。

The unit conversion of often-used formulas in an important task, and is an significant step in combining theoretical research and actual application.SI units system consists od SI base units and SI field units,the former are used in the theoretical derivation of formulas in the petroleum reservoir engineering,the latter are used in the calculation of actual field problems.So,the units conversion from SI base units to SI field units is necessary so as to achieve correct results.This paper introduces the often-used SI base and field units in the petroleum reservoir engineering and the conversion constants between them,and demonstrates how to transform from SI base units to SI field units in practice.
