Abstract

Abstract

The principle method of the Differential Strain Analysis technique is briefly recommended. We tested the rock samples taken from the Well Tun-1 which was located in Luoyang-Yichuan basin in Henan Province. The results shows that the maximum horizontal principal stress is NW orientation (141°-157°) in the well of 1153.4~1167.8 m, which is consistent with the maximum horizontal principal stress orientation of the drill collapsing ellipse macro axis. Its value is less than vertical stress, and belongs to normal fault stress. The principal stress increases with depth linearity. Advice for the injection-production well pattern in this area is given, that is the pattern shall not parallel to 141°-157° orientation.
