Abstract
The mathematical deifnition of horizontal well target with multiple control points was set, so as to describe it accurately in the drilling design software. The vector algebra was used as the mathematical tool, and the external boundary curve of target was mathematically deifned by using the normal plane coordinates of an arbitrary point on the target design axis. Then, a new concept of cuboid target with curved boundary was proposed and the calculation formula was also established for the external boundary curve of target. And ifnally, the drilling design software was applied in ifeld. It is shown that the deifnition of cuboid target with curved boundary is reasonable and its calculation formula is accurate and can be easily presented in programming. Moreover, it was made possible to draw horizontal well targets accurately in horizontal projection, vertical projection, proifle expansion and 3D diagrams.关键词
