Choice of Squeezing Pressure of Superfine Count High Density Fabric and Fine Count High Density Fabric;

By using the method of on-the-spot testing,the processing parameters such as squeezing pressure and squeez- ing width of three kinds of advanced sizing machine,namely SUCKER S432 sizing machine,TSUDAKOMA HS20-Ⅱ sizing machine and local-made GA 308 sizing machine are studied.

Research on effect of sizing pressure on quality of sized yarns;

According to application of wire line formation tester, using data of formation pressure, mud pressure, etc to estimate reservoir property and fluid characteristics, examples validates the feasibility of using formation pressure to judge reservoir property.

In this paper, soil mechanical parameters in construction of pipeline crossing are analyzed and the new concepts of minimum required mud pressure and maximum allowed mud pressure are put forward.
