胜利油田自1979年开始应用地层倾角仪以来,已在济阳坳陷测井五十多口,从而积累了地层倾角资料的计算机处理和地质解释的一些经验。实践表明,利用地层倾角测井资料,可以确定断层性质、断点深度和断面倾向,判断不整合面位置,校正根据地震(或钻井)资料绘制的构造图,计算斜井(或高倾角岩层)的地层真厚度。此外,地层倾角资料还可用于研究沉积特征。本文仅就如何应用地层倾角测井资料确定地质构造的问题作一叙述。文中提到的倾角矢量图,都是指长相关对比矢量图。
Since the application of the stratum inclinometer in Shengli Oilfield in 1979, it has logged more than 50 wells in the Jiyang Depression, thus accumulating some computer-processing and geological interpretation of stratum dip data. Practice shows that using the dip data of stratigraphy, we can determine the nature of faults, the depth of breakpoints and the tendency of sections, judge the position of unconformities, correct the tectonic map drawn from the seismic (or drilling) data, calculate the inclined wells (or high-dip strata) The true thickness of the formation. In addition, stratum dip data can also be used to study sedimentary features. This article only describes how to determine the geological structure by using dip data from stratigraphy. Inclination mentioned in the article vector, all refers to the long correlation vector.
