METHOD FOR DETERMINING POSITION REGARDING horizontal wellbore top and bottom of the productive formation BASED ON LOGGING low-frequency acoustic wave reflection

摘要

A method for determining the position of the horizontal wellbore relative to top and bottom of the productive formation on the basis of low-frequency acoustic logging on reflected waves, characterized in that, to improve the efficiency and accuracy of logging data interpretation, the position of the top and base layer is determined by direct measurements of the time of the acoustic wave path on the device disposed in a horizontal wellbore, the producing reservoir interface and the host species.
