In the graphical method of the orthographic axonometry, the principal direction of ellipse and the size of the major, radius are worked out according to the orthographic projection theory, while the size of the minor radius is worked out according to the relation between the minor radius deformation coefficient and the deformation coefficient of normal vector of circular plane. In the method of calculation, the direction of projection and the normal vector of circular plane are taken as two vectors, and the size of the minor radius is found by using their scalar produt. In the graphical method of the oblique axonometry, the affine transformation is taken as the ellipse's principal direction and the size of the principal radius. In the method of calculation, the property of ellipse is used to build three equations to find out the size of major radius R and minor radius r of the ellipse, as well as the angle θ between the major axis and the X axis.

水平井钻井技术已在世界20多个主要产油国的4000余口井中开花结果。由于水平井是一项复杂的系统工程,目前对其技术经济的分析和综合效益的评价尚不完善,国外多从水平井钻井成本下降和产量(或产能)增加两个方面评价,国内正在探索建立自己的水平井经济评价标准.本文通过综述国内外大量水平并钻井的经济性评价结果,提出了水平井技术经济评价新思路──指标体系和方法体系,藉以促进我国水平井技术发展和水平井效益提高,并建议开展超短半径水平井技术研究以挖掘东部老油田的增产潜力。
