Abstract
Способ определения пространственного положения подводного трубопровода методом магнитометрической съемки, включающий измерение модуля вектора индукции магнитного поля Земли (ВИМПЗ) при помощи магнитометров, установленных на носителе, буксируемом за судном, определение градиента модуля ВИМПЗ и совместную обработку магнитометрических данных и координат магнитометров, отличающийся тем, что все магнитометры размещают совместно с точкой приема сигнала на одном вертикальном носителе, координаты магнитометров определяют расчетным путем на основании измеренных координат вертикального носителя и измеренных углов наклона вертикального носителя с учетом рассчитанных поправок на деформацию вертикального носителя, причем расчет координат каждого из магнитометров выполняют синхронно с измерением упомянутым магнитометром модуля ВИМПЗ, магнитометрическую съемку осуществляют путем криволинейного перемещения вертикального носителя над трубопроводом, при этом измерение модуля ВИМПЗ выполняют в заданных предварительно точках пересечения траектории движения вертикального носителя с трубопроводом, а в процессе совместной обработки магнитометрических данных и координат магнитометров определяют x, y, z координаты в точках пересечения траектории движения вертикального носителя с трубопроводом, найденных по аномальным значениям модуля ВИМПЗ, и по упомянутым координатам судят о пространственном положении трубопровода. A method for determining the spatial position of an underwater pipeline using magnetometric surveying, including measuring the module of the Earth's magnetic field induction vector (VIMPZ) using magnetometers mounted on a carrier towed behind a vessel, determining the gradient of the VIMPZ module and processing the magnetometric data and the coordinates of the magnetometers together, characterized in that all magnetometers are placed together with the signal receiving point on one vertical carrier, the coordinates of the magnetometers are determined by the calculated path based on the measured coordinates of the vertical carrier and the measured angles of inclination of the vertical carrier, taking into account the calculated corrections for the deformation of the vertical carrier, and the calculation of the coordinates of each magnetometer is performed synchronously with the measurement of the mentioned magnetometer of the VIMPZ module, the magnetometric survey is carried out by curvilinear movement of the vertical carrier above the pipeline, while the measurement VIMPZ module is performed at predetermined points of intersection of the vertical path of the carrier with the pipeline, and in the process of joint processing of the magnetometric data and the coordinates of the magnetometers, the x, y, z coordinates are determined at the points of intersection of the path of the vertical carrier with the pipeline, found by the abnormal values of the VIMPZ module, and the spatial position of the pipeline is judged by the mentioned coordinates.
