VSP 的纵、横波记录与处理的目的,是确定利用市场上能够得到的方法是否能从某一 VSP 标准纵波中提取有效的波型转换横波。该测区位于怀俄明州 Cheyenne 东北18英里的 Sile 油田。该油田产于破碎的 Niobrara 灰岩中。其上为5000ft 的 Pierre 页岩,是一种单独研究各向异性和波的传播特性的对象,其下面是几个有远景的储油砂岩,包括 Codell D 和 J 岩层。 The purpose of VSP vertical and transverse wave recording and processing is to determine whether the available mode-converted transverse waves can be extracted from a VSP standard longitudinal wave using commercially available methods. The area is located in Sile Field, 18 miles northeast of Cheyenne, Wyoming. The field is produced in crushed Niobrara limestone. The 5,000-foot Pierre shale is the object of a unique study of anisotropy and wave propagation characteristics. Below are several vistas of oil-bearing sandstone, including the Codell D and J rock formations.
