摘要
水平井测井仪器经过地层界面时,测井曲线会出现延迟现象,本文结合地质录井资料和水平井井眼轨迹与油藏关系成图系统软件,在标定地层界面的前提下求得延滞区间长度,进而求得地层界面间的地层倾角和方位角,来确定水平井井旁构造特征及其空间展布。
When logging tools in horizontal wells passes through stratigraphic boundaries, the logging curve will show the delay phenomenon. In this paper, based on the geological logging data and the mapping system software of the relations between well trajectory and reservoir in horizontal log, it obtains the delay interval length under the condition of the calibration of stratigraphy and then obtains inclination and azimuth of stratigraphic boundaries, which determines the characters of well location structure and its spatial distribution.
