本文对油田用各种测井仪的优缺点进行了比较,说明了微球形测井仪是目前最先进的测井仪器,而微球极板是该测井仪的关键部件。本文经过对极板工作原理的探讨,指出制作极板的材料应具备的性能以及选用的主体材料及选用的填充剂、促进剂、硫化剂等助剂的品种及数量。同时,对成型工艺也进行了研究,选择了两步法成型。
This paper compares the advantages and disadvantages of various logging tools used in oilfields. It shows that microspherical logging tools are the most advanced logging tools at present, and the microsphere polar plates are the key components of this logging tool. After the discussion of the working principle of the plate, this paper points out the properties of the materials used to make the plate and the selection of the main material and the selection of fillers, accelerators, curing agents and other additives varieties and quantities. At the same time, the molding process has also been studied, chose two-step molding.
