水平井生产管电化学切割动态分析及参数选择

在分析固定阴极电解加工参数并推导出加工量与其相应加工时间关系的计算公式后 ,经计算机处理 ,得到地面条件下和井下电化学切割水平井生产管过程中 ,被切割生产管内孔半径与切割时间的关系曲线。分析研究认为 :电化学切割过程中 ,外加电压对切割速度影响较大 ,选择电压既要满足切割速度的要求 ,又要考虑电源设计的可行性、施工的方便性及成本核算 ;阴极的结构和尺寸决定切割初始间隙的大小及均匀性 ,对切割速度有较大影响 ,设计阴极时 ,一方面要考虑快速高效切割的要求 ,还要考虑有利于阴极的送进和定位 ;电解液的电导率也直接影响切割速度 ,故以采用KCl电解液较为适宜

Dynamic analysis and parameters selection of electrochemical cutting of production pipe in horizontal hole

The parameters for electrochemical machining (ECM) by stationary cathode were analyzed, the relational expressions for process amount and process time were derived, and the relationship curve for the inside radius of the cut production pipe and the time for ECM of the production pipe in a horizontal hole was obtained. In the course of ECM, voltage has gnat influence on the cutting speed, therefore it should meet the need of the cutting speed in consideration of the feasibility of the power source design and convenience of construction and cost accounting. The structure and size of the cathode determine the initial intervals cut and their uniformity, therefore in the design of the cathode, ale requirement for quick and high-efficiency cutting should be satisfied, and the feeding and positioning of the cathode need to he considered. The conductivity of the electrolyte influences directly the cutting speed, KCI electrolyte is recommended to use.
