倾角测井矢量图可以标示出井眼范围内各深度点的地层产状,一定的地层构造形态在矢量图上有一定的倾角矢量组合模式。通过正演计算,总结出了19种褶曲和断层等构造组合模式的样板及在一口井内各构造模式间的“串”、“缺”、“嵌”连接规律。对照组合模式样板进行矢量组合模式识别,采用“倾角矢量逐点叠加法”,可把井眼范围纵向排列的倾角矢量转换成任意方位的地层视产状,绘制构造剖面图。用多个剖面的地层空间坐标数据可绘制倾角构造平面图,确定钻遇构造的形态。据此原理,编制了一套倾角测井构造解释软件系统。
Inclination logging vectors can be used to indicate the occurrence of strata at various depths within the borehole range. Certain stratigraphic configurations have a vector model of dip angle vectors. Through the forward calculation, 19 kinds of tectonic combination models such as fold and fault are summed up, and the “string”, “missing” and “embedded” connection rules among various structural modes in a well are summarized. The pattern of vector combination pattern is identified by the pattern of combination pattern. By using the “point-by-point vector method of inclination angle vector”, the inclination vector of longitudinal wellbore range can be converted into any azimuthal stratum appearance, and the structure profile is drawn. The multi-profile formation coordinate data can be used to draw the dip plane and determine the shape of the drilling structure. According to this principle, a set of dip logging structure interpretation software system was compiled.
