Abstract

The invention provides a well logging tool string and a manufacturing process of the well logging tool string, the well logging tool string comprises a first shell section, a second shell section and a third shell section which are sequentially connected in a preset direction and are all of a cylindrical structure, and a cylindrical cavity of the third shell section comprises a first cavity section and a second cavity section which are distributed in the preset direction and are mutually independent; the first cavity section is communicated with the cylindrical cavity of the second shell section; the fixing assembly is arranged in the first shell section and is used for being connected with a cable so as to fix the cable; the first locking piece is arranged on the fixing assembly and the first shell section in a penetrating mode. The one-way valve assembly is arranged in the second shell section; and the conductive assembly is arranged in the second cavity section and penetrates out of the second cavity section, and the first end of the cable penetrating into the second cavity section is electrically connected with the conductive assembly. According to the logging tool string, the problem that in the prior art, a logging tool string is inconvenient to manufacture is solved.

Description

technical field [0001] The invention relates to the field of petroleum logging equipment, in particular to a logging tool string and a manufacturing process of the logging tool string. Background technique [0002] In the process of oilfield development and production, in order to understand the internal conditions of the wellbore, well logging is usually used for analysis and comparison. [0003] Conventional well logging uses a separate cable for related operations. Due to the weight and structural problems of the cable itself, the running depth is limited, and the internal cable connection is fixed and rigid, which reduces the success rate of logging. On the other hand, conventional logging cannot complete Well killing operations further limit the scope of logging operations. Contents of the invention [0004] The main purpose of the present invention is to provide a logging tool string and a manufacturing process of the logging tool string to solve the problem of inco...
