Abstract

The invention relates to a well control logging cable hanger and a tool assembly and a using method thereof. The well control logging cable hanger comprises a wellhead chuck, a hanging main body, a split slip, a slip pressing sleeve, a double-female joint, an elastic threaded ring and a split retaining ring; the matched tool component is composed of an ejector rod and a pressing cap, wherein the split retaining ring corresponds to the elastic threaded ring in structure and can be matched with the elastic threaded ring to form an axial elastic clamping matching structure; a logging cable can bequickly and directly hung by using the well control logging cable hanger; an oil well drill rod can be quickly clamped with the hanging main body; and therefore, redundant time for pulling out a logging instrument can be saved, the connecting speed of an oil well drill rod can be increased, the wellhead treatment time of emergency situations in the well logging process can be effectively shortened, the risk corresponding speed in the well logging process can be increased, the risk treatment capacity in the well logging process can be improved, possible risk hidden dangers and possible economic losses are reduced, and a more reliable guarantee is provided for safe production of an oil field.

Description

technical field

[0001] The invention relates to a cable hanger and its tool assembly, in particular to a well control logging cable hanger and its tool assembly. Background technique

[0002] In oilfield drilling and production, all newly drilled open-hole wells without casing usually require logging operations to measure various information in the reservoir or production layer along the wellbore, and provide relevant information for various stages of oil and gas reservoir exploration and development At present, the logging operation of open-hole wells generally uses the drilling derrick to lift the sky pulley, and at the same time, the ground pulley is installed on the ground, and the logging cable connects the logging instrument or electrode system with the ground logging instrument The connection method is suspended by the logging cable, and the downhole instrument is lowered into the wellbore filled with drilling fluid, and the measurement work is completed during the li...
