吉林红岗油田低阻油层成因机理研究

低阻油气藏在全国各大油田都有发现,如渤海湾地区、南海莺歌海盆地、塔里木塔北地区等,形成低电阻率油层的机理不尽相同,但低电阻率产生的根本原因一般是束缚水含量高、粘土矿物的附加导电能力相对较强、存在导电矿物、油藏幅度低等。为了正确识别低阻油层,评价油藏条件下的饱和度,必须搞清低阻油层的低阻特性和形成机理。本文从可能引起低阻的各方面原因对吉林红岗油田泉四段低阻油层的成因机理进行了研究。

Forming principle research of oil layer with low resistivity in jilin oil field

Oil reservoir with low resistivity are very common in china,such as in Bohai Sea Bay,Southern Sea yinggehai basin,Talimu northern region,and so on.Formation principles for low resistivity layer are diverse in different regions,but the fundamental causalities are similar: high content of bound water,strong attached conductance of clay mineral,existence of conductive mineral,and low amplitude of reservoir.In order to recognize oil layer with low resistivity correctly,and evaluate saturation of reservoir,it is very significant to recognize property and forming principles of low resistivity reservoir. This article searches the diverse forming principles in honggang quan-4 low resistivity layer of jilin oil field.
