Resonance absorption of p-polarized electromagnetic wave by mode conversion in magnetized inhomogeneous plasma is investigated numerically as external magnetic field is perpendicular to density gradient.
用数值方法研究磁化非均匀等离子体(磁场与密度梯度垂直)中模转换机制对p极化电磁波的吸收效应,重点考虑磁场对吸收率的影响,结果表明:与非磁化等离子体相比,磁场的加入使得吸收率曲线相对入射角的分布发生小的偏移,吸收率为零的位置不是发生在零度入射(即垂直入射)时,而是在一个负的入射角位置,垂直入射时有不为零的吸收率,且正角度范围与负角度范围的峰值吸收率不相等,磁场提高了正入射角范围内的峰值吸收率而降低了负角度范围内的峰值吸收率(或反过来,这取决于磁场方向)。

白碱滩油田六中区克下组为冲积扇沉积,储集层非均质性严重,在对这类储层进行综合评价时,除了用到孔隙度、渗透率和泥质含量等常规评价参数外,在这里增加了变异系数、突进系数和级差三个参数,使得非均质性的作用在储层综合分类评价中得到充分体现;然后应用聚类分析将储集层分为三种类型,其中Ⅰ类储层最好,Ⅱ类储层次之,Ⅲ类相对较差;最后对每个单层中三类储层的分布进行了分析,进而指导油田的进一步开发。
