GEOPHYSICAL CABLE CLEANING DEVICE Russian patent published in 2022 - IPC E21B33/08 

FIELD: geophysical cable cleaning.

SUBSTANCE: invention relates to a device for cleaning a geophysical cable. The device comprises a hollow cylindrical body with a cylindrical hole, an annular clip forming a central hole in the state closed along the split planes for the passage of the cleaned geophysical cable, an elastic cuff. The hollow cylindrical body from the side surface to the center has a radial slot with a width h. The annular holder is made in the form of two semi-cylinders installed in a cylindrical hole of a hollow cylindrical body. The inner surfaces of the semi-cylinders, which form a central hole in a state closed along the parting planes, are equipped with semi-annular toothed notches, and the elastic cuff is placed in a hollow cylindrical body above the annular holder and is made tubular with a radial cut from the periphery to the center. From above, the elastic cuff has the possibility of being compressed by means of a threaded connection relative to the annular cage by a sleeve screwed from above into a hollow cylindrical body. The sleeve is equipped with a radial slot of width a from the periphery to the center. The widths h and a, respectively, of the radial cut of the hollow cylindrical body and the bushing, are greater than the diameter d of the cleaned geophysical cable. From below, the hollow cylindrical body is equipped with two longitudinal grooves located at an angle of 180 degrees with respect to each other. The hollow cylindrical body is fixed on the wellhead flange by means of L-shaped pins with a gap. The hollow cylindrical body is made with the possibility of radial displacement relative to the wellhead flange within the longitudinal slots.

EFFECT: improving the efficiency and quality of cleaning the surface of the geophysical cable, eliminating oil pollution of the working site, operating equipment and wellhead equipment, as well as the surrounding area of ​​the well, improving working conditions for operators of the geophysical lift, expanding the scope of the device.
