井网设计是油气田开发中数值模拟、油气田开发方案编制和井网调整的重要内容。随着油田开发水平的不断提高,水平井开发在油田开发中所占比例逐年上升,而水平井交错七点注水井网是水平井开发中常用的井网形式。目前石油系统油田开发还没有成型的水平井井网设计软件,本文在研究水平井交错七点注水井网井位分布规律的基础上,通过直角坐标系坐标间关系和三角形边角关系,采用VBA编程,实现了水平井交错七点注水井网坐标设计、井号编制、井别判别,从而提高了井网设计的效率。
Well pattern design is an important part of numerical simulation of oil and gas field development, formulation of oil and gas field development plans and well pattern adjustment. With the continuous improvement of oilfield development, the proportion of horizontal well development in oilfield development has been increasing year by year. The horizontal well staggered seven-point water injection well pattern is commonly used in horizontal well development. At present, there is no horizontal well pattern design software developed in petroleum system oil field. Based on the study of the well pattern distribution of horizontal wells with seven injection wells, the relationship between the coordinates of the rectangular coordinate system and the triangle corner is studied. The VBA Programming, to achieve a horizontal well staggered seven water injection well coordinate design, well number preparation, well do not distinguish, thus improving the efficiency of well pattern design.
