It was considered that the control of the PRD fluid performance and the dosage of flow pattern adjusting agent PF-VIS were the key of the technique. The viscosity of PRD spudding fluid increased rapidly with the decrease of shearing rate, it indicated that it had good sand carrying ability. The spudding fluid was good capacity of high temperature stability under the low shearing rate, its viscosity was much higher than that of traditional drilling fluid, it was beneficial for cutting carrying in big deviated wells and preventing the formation of cutting bed.

认为要控制好PRD弱凝胶钻开液的性能，流型调节剂PF-VIS的加量是关键；PRD弱凝胶钻开液的粘度随着剪切速率的降低而急剧上升，显示了其优良的井壁携砂带砂性能；PRD弱凝胶钻开液体系具有较好的高温稳定性；PRD弱凝胶钻开液体系在低剪切速率的高粘度，大大高于传统聚合物钻井液，有利于在大斜度井携带岩屑以及防止岩屑床的形成。

The swaged machine in our company is UNIFLEX H325B of German .with advantages that the swaged dates can be controlled by computer to get accuracy.

Cutting process of soft tissue and organs is very important in virtual surgery simulation. Tetrahedron is widely used to construct the geometric model of virtual organs. Efficient methods must be developed to split or merge tetrahedrons in order to adapt to topology changes during cutting process. The main parts of this thesis are the two chapters on "Reconstruction of Tetrahedrons" and "Stability of Tetrahedrons".Main research work I have done is listed as follows:1 Reconstruction of Tetrahedrons.

人体软组织及器官的切割仿真是虚拟手术仿真的重要组成部分，软组织及器官的几何模型普遍采用四面体模型，切割的同时，软组织及器官的拓扑结构发生变化，模型中的部分四面体基元必须能够通过分裂或合并以适应上述变化，医学数据在三维场景中的交互和可视化是手术仿真的基本要求，因此，第二章&四面体重构&以及第三章&四面体单元稳定性&是本文重点讨论的两个部分。

There is political as well as economic strategy behind their approach, which triangulates between cutting spending too early and cutting it too little.

这些措施包括政治和经济上的对策，尽力在过早削减开支和削减开支的力量太小之间找到平衡的方法。

They are sensitive to cutting, and as the cutting waxes they will totally disappear.
