本文描述了一种运用置入盐丘的定向三分量检波器确定盐丘形状的方法。在地表进行激发, 其井源距范围和炮点的方位角取决于深度和感兴趣的翼部。我们提出了两种偏移旅行时间信息的射线追踪方法。第一种方法是利用初至波的射线方向及盐丘和沉积层中的P波速度来确定盐丘侧翼的唯一点。第二种方法是利用射线方向。盐的P波、S波速度以及盐丘-沉积层界面产生的直达波和横波之间的旅行时差。在对合成地震资料进行偏移之后,两种方法的结果均与原始模型吻合得很好。P-S波方法的主要优点是它与沉积层的速度无关。采集这些资料最经济有效的方法是,把一串三分量检波器胶结在盐丘中的套管上。该方法的关键步骤是确定胶结后的检波器的方向。本文描述了雪茯龙公司和哈里伯顿公司合作开发的一种方法。该方法是把检波器串装在套管的外面,它们与套管的方向是已知的。在每个检波器的外壳上, 于沿与套管相垂的水平检波器分量轴上安装一个放射性小球。装有陀螺仪的小口径伽马射线测井仪可以找到放射性小球,这样便确定了检波器的方向。

During oil/gas exploration in an area, there is a question as to whether methane in the strata was generated \%in situ\% mainly by thermal degradation of local organic matter. The key to the question is whether the kerogen could produce methane of more than 80 mL/g TOC, when its \%R\%\-o increased from initial (0.36%) to current value of 0.70% during thermal evolution. The authors have made efforts to answer this question by the kinetics method. First, a series of pyrolysis experiments were carried out to obtain data of methane yield and \%R\%\-o evolution, from which kinetic parameters of methane and \%R\%\-o were derived; then these parameters were extrapolated to the geological condition and finally, a methane yield, 96 mL/g TOC, was predicted. The result suggests that from the view of hydrocarbon generation, methane in the seam should be from thermal degradation of local kerogen.

In the paper"A numerical investigation of the acoustic mode waves in a deviated borehole penetrating a transversely isotropic formation"by Liu et al.[1]numerical experiments are reported for a dipole sonic logging scenario with a deviated borehole penetrating a VTI anisotropic *** such a situation it is important to clearly define the meaning of group and phase velocities as this has led to much confusion in the literature as discussed by Miller,Horne and Walsh[2].
