Description

TECHNICAL FIELD

[0001] The utility model belongs to the petroleum logging technical field relates to the logging marker fixing device of being able to clean mud. BACKGROUND

[0002] The logging marker is an important part of the petroleum logging equipment. It is mainly used for marking the depth on the logging cable to record the depth position of the downhole instrument accurately. During the logging process, the marker will make marks at certain intervals or at the key depth position along with the lowering or lifting of the cable. The existing advanced marker adopts the electromagnetic induction principle. When the marker is needed, the electromagnetic device inside the marker will generate a local magnetic field change or electromagnetic signal on the cable. The depth sensor in the logging system can detect the electromagnetic change to determine the depth mark. However, during the lifting of the cable, the drilling mud will adhere to the cable. The mud not only brings inconvenience to the logging operation, but also pollutes the environment of the operation site. Therefore, there is an urgent need for a logging marker fixing device that can clean the mud.

[0003] The Chinese utility model patent with the authorization announcement number CN201013295Y, the application date of February 14, 2007, and the authorization announcement date of January 30, 2008, provides a dual-purpose anti-magnetic wellhead device. The device includes a magnetic marker fixing frame located at the wellhead. The magnetic marker fixing frame is fixed with a magnetic marker. The magnetic marker is opposite to the center of the cable. There is an inner circular magnetic guide pipe cylinder in the inner wall of the oil well casing. There is a metal circular pipe cylinder in the inner wall of the inner circular magnetic guide pipe cylinder. There is a gap between the inner wall of the metal circular pipe cylinder and the logging cable. When the logging cable passes through the inner wall of the pipe, the inner wall can scrape off the mud adhered to the logging cable. Then the mud adhered to the logging cable can be washed away by the high-pressure gas jetted out through the air hole on the inner wall of the pipe. However, the device scrapes off the mud through the gap in the inner wall of the pipe first, and then washes the mud away by the high-pressure gas. Since the air holes are only distributed on both sides of the cable, it is difficult to ensure that the mud is completely cleaned. CONTENT OF THE UTILITY MODEL
