Abstract

Предложен способ определения глубины скважины. Способ включает определение изменения подвешенной нагрузки бурильной колонны между первым и вторым моментами времени. Определяют изменение осевого положения верхнего участка бурильной колонны между первым и вторым моментами времени. Ожидаемую величину сжатия бурильной колонны, связанного с изменением подвешенной нагрузки, корректируют для перемещения нижнего участка бурильной колонны за период между первым и вторым моментами времени. Положение нижнего участка бурильной колонны вычисляют по изменению осевого положения и откорректированной величине сжатия бурильной колонны. В одном варианте корректировка включает оценку перемещения бурильного долота путем определения осевого движения бурильной колонны около поверхности земли в промежутке времени, в котором отсутствует изменение подвешенной нагрузки бурильной колонны.Отчет о международном поиске был опубликован 2004.01.08.
