Abstract
Disclosed in the invention is an apparatus for identifying entrance of a production logging instrument into a lubricator. The apparatus comprises an induction coil, a micro-current detection switch, and an acousto-optic alarm device. The induction coil senses a magnetic field change that is caused when a production logging instrument enters a lubricator; the micro-current detection switch detects an induction current caused by the magnetic field change and is excited to be turned off to trigger the acousto-optic alarm device to carry out alarming. Therefore, whether the instrument enters the lubricator can be identified accurately; and the apparatus can be used conveniently at field. Moreover, the sensitivity, stability and practicability of the apparatus are high; and even when the production logging instrument passes at a low speed, alarming can be trigged, thereby effectively avoiding an instrument falling risk into the well due to wrong judgment.
