摘要
运用多元线性回归等方法研究临南油田夏 70块沙河街组沙三段低电阻率油层的形成机理。认为形成影响该区油层低阻的主要因素是高束缚水饱和度和地层水的高矿化度 ,润湿性的影响也是一个不容忽视的因素 ;
The multidimensional linear regression method was used in this article to study the formation mechanism of low resistance oil layer at Sha 3 Segment, Shahe Street of Block Xia-70 in Linnan Oilfield. It has been pointed out in the paper that the main factor of the low resistance oil layer in this area was highly-restricted water saturation and highly-mineralized stratum water. The influence of dampness was also a factor that can't be neglected. The append electric conductivity of mud was not a dominant factor to influence the low resistance oil layer in this area.
