The Schur_Weyl_Brauer duality relation between A,B,C, and D type of Liealgebras and their centralizer algebras, and its quantum version is emphasized.

特别强调了关于A，B，C，D型李代数及其量子情形与其中心代数之间的舒尔魏尔布劳双关性关系。

Scene data indicate that in the process of actual making the casing into the Horizontal Well ,people used to reduce friction coefficient between the stratum and the Casing, Change the friction type between the casing and the wall,use special casing and centralizer with oriented ring, even join the slurry in the internal casing in order to increase self-casing, etc.

现场资料表明，在实际套管下入过程中，人们往往采用的是减小套管与井壁之间的摩擦系数、改变套管与井壁间的摩擦类型，使用带有导向环的套管和扶正器，甚至在套管内部加入泥浆，以增加套管自重等方法，但这些方法并没有改变套管下入驱动力减少的现实，不能从根本上解决套管下入困难的问题。

In order to enhance continuous-running efficiency,a special centralizer was developed and eliminated the tie back sting,and one trip was needed for the performance of sand washing by slim pipe.

为提高作业时效，成功研发了一种新型套管丢手内专用冲砂扶正工具，其省略了回接管柱，直接在大套管内下入小油管就可准确进入丢手内冲砂。
