摘要: 应用“点在多边形中”判断和确定勘探或开发区块内的井位,采用垂直射线与多边形交点个数的奇、偶性来判断井点是否在多边形内部,解决了任何复杂区块内井点的判别问题。在井位判断和确定过程中自动化程度高,具有精度高、操作简单和工作效率高等特点,目前该方法已在生产中进行了推广应用。Abstract: Well locations in exploration and/or development blocks can be determined according to "well points in polygon". Whether the well points are located in polygon can be determined according to the number of crossing points of perpendicular with the polygon being odd or even. This method can solve the problem of well point determination in any complex blocks. It is characterized by high level of automation, high accuracy, simple operation and high efficiency and has been popularized and applied in production at present.
