进行地层破裂(渗漏)试验。
The gradient PPS/FEP composite anti-corrosive coatings were prepared on carbon steel. The bonding strength of all coating systems was determined by the pull-off test.
在碳钢表面制备了具有梯度结构的PPS/FEP复合防腐蚀涂层，采用拉开法测定了各涂层体系的结合强度。
During thermal recovery, to estimate swept volume with pressure fall off test is very important, while hest loss effect of the formation can not be ignored during analysis of pressure fall off test.
在热采项目中用压力降试井来估算蒸汽波及体积是非常重要的，而地层中热损效应在压力降试井分析中又是不可忽略的。
