Abstract
В заявке описаны компьютерно-реализуемые способ и система определения относительных положений ствола скважины и объекта, когда ствол скважины представлен первым эллипсом, а объект представлен вторым эллипсом. Первый эллипс отображает неопределенность координат ствола скважины, а второй эллипс отображает неопределенность координат объекта. Способ включает шаги: приема входных данных, касающихся вычисленного или предполагаемого положения ствола скважины и объекта, при этом положение ствола скважины содержит первый набор параметров, характеризующих первый эллипс, а положение объекта содержит второй набор параметров, характеризующих второй эллипс, расчета коэффициента расширения, отображающего величину, на которую может быть расширен один из двух эллипсов или первый и второй эллипсы относительно одного из двух соответствующих наборов или первого и второго наборов параметров эллипсов, чтобы первый и второй эллипсы соприкасались, при этом расчет коэффициента расширения предусматривает вычисление и решение уравнения четвертой степени, основанного на геометрии эллипсов, и вычисления на основании рассчитанного коэффициента расширения координат, указывающих относительные положения ствола скважины и объекта.The application describes a computer-implemented method and system for determining the relative positions of a wellbore and an object when the wellbore is represented by the first ellipse and the object is represented by the second ellipse. The first ellipse represents the uncertainty of the wellbore coordinates, and the second ellipse represents the uncertainty of the object's coordinates. The method includes the steps of: receiving input data relating to the calculated or estimated position of the wellbore and the object, while the wellbore position contains the first set of parameters characterizing the first ellipse, and the object position contains the second set of parameters characterizing the second ellipse, calculating the expansion coefficient representing the value , to which one of the two ellipses or the first and second ellipses can be expanded with respect to one of the two corresponding sets or the first and second sets of ellipse parameters so that the first and second ellipses are in contact, while calculating the expansion coefficient involves calculating and solving a fourth degree equation based on on the geometry of the ellipses, and calculations based on the calculated spread factor of coordinates indicating the relative positions of the wellbore and the object.
