摘要
孔隙度是储层评价的重要参数之一.密度测井是一种重要的孔隙度测井方法,在石油勘探领域常常被用作确定岩层孔隙度.通过研究密度测井的基本原理、仪器构成、刻度方法等,推导出不同情况下孔隙度的计算公式.并利用该公式进行Matlab编程,对实际测井数据进行处理,计算了多个井段的岩层孔隙度,证明了密度测井在孔隙度计算方面具有很高的应用价值.
Porosity is one of the important parameters in reservoir evaluation. Density logging is commonly used to determine the porosity of rock formations in petroleum exploration. With studies on basic principles, instrument and calibration method of density logging, the calculation formulas for porosity in different situations are derived. Such formulas are applied in the Matlab program to process the practical logging data and calculate porosities of rock formations in multiple well sections. The result shows that the method of density logging is highly applicable in porosity calculation.
