Study of Correction to Dual Laterolog of Directional Well in Heavy Oil Reservoir
摘要
Abstract
Due to the change of directional well's angle,environmental factors,such as layer thickness,shoulder bed,borehole,mud and so on,have great influence on dual laterolog,and this may lead inaccurate result of well log interpretation.The dual laterolog curves must be corrected before well log interpretation.Based on the characteristics of directional well,marker beds of its adjacent vertical wells can be used to correct its dual laterolog.Firstly,choosed are multi-group directional wells whose depths are corrected by minimum curvature method and vertical wells to select marker beds which includes mudstone formation and compact layer.Then,established are the correction charts with the data of marker beds and correct dual laterolog.Finally,given is the test of the result.This paper takes Qigu formation of Fengcheng oilfield as a study example.The result of well log interpretation after correcting dual laterolog is similar to the real situation of the study area.关键词
