笔者研制的ZDCAD软件系统主要用于油田上调整井和开发井的地质设计,可对层位数据、断点断距、完钻井深度及地层倾角等参数自动进行预测和计算。系统对难度较大的断层井的设计采用了曲面拟合,平面拟合及线性插值等数学处理方法。尤其对确定设计井及其周围井的盘位提出了新的分盘方法。程序采用了模块化结构,设计结果既可在屏幕上显示修改,又可以表格方式打印输出。 The ZDCAD software system developed by the author is mainly used for the geological design of uphole and development wells in the oilfield, and can automatically predict and calculate the parameters such as horizon data, breakpoint offsets, drilling depth and formation dip. The system uses mathematical methods such as surface fitting, plane fitting and linear interpolation to design the more difficult fault wells. In particular, a new sub-plate approach is proposed for determining the location of the design well and its surrounding wells. The program uses a modular structure, the design results can be displayed on the screen changes, but also the form of print output.
