Abstract
The utility model relates to a pressure-bearing housing of a petroleum logging instrument, which comprises a connector body and a housing main body, wherein external threads are formed at one end of the connector body; internal threads are formed at one end of the housing corresponding to the connector body; the connector body and the housing main body are welded into a whole after threaded connection; the other end of the connector body is connected with the upper port of the logging instrument; external connecting threads are formed on the outer wall of the upper port of the logging instrument; the other end of the housing main body is connected with the lower port of the logging instrument; and internal connecting threads are formed on the inner wall of the lower port of the logging instrument. By changing the structure of components, the pressure-bearing housing of the petroleum logging instrument can greatly save precious metal materials and improve lumber recovery of the metal materials to 62.5 to 79 percent according to measurement and calculation. Besides, the pressure-bearing housing of petroleum logging instrument can meet various operating requirements of well logging via high-temperature and high-pressure test and multi-aspect verification in the practical logging operation.
Description
Technical field:
The utility model relates to a kind of oil well logging instrument bearing shell.
Background technology:
Former project organization can satisfy the use job requirement of oil well logging instrument.But owing to adopt global design, its problem is: after deep hole machining, a large amount of metal material consumes with the form of smear metal.
Because the metal material that the oil well logging instrument bearing shell adopts is more valuable, high-intensity alloy material (as TC4), material " lumber recovery " only is 32%.Thereby, take morely and wasted social precious metal material resources.
The utility model content:
The purpose of this utility model provides a kind of oil well logging instrument bearing shell of selecting the split-type structural design for use, thereby changes component processing process, the resource of saving the precious metal material to greatest extent.
Oil well logging instrument bearing shell described in the utility model is made of fittings body and two parts of housing main body; Fittings body one end is provided with external screw thread, the corresponding end of housing main body and fittings body is provided with internal thread, be welded as a whole after fittings body and the housing main body thread connection, the fittings body other end is connected with interface on the logger, the interface outer wall is provided with outer connecting thread on the logger, the other end of housing main body is connected with the logger lower interface, and logger lower interface inwall is provided with interior connecting thread.
The utility model oil well logging instrument bearing shell has changed design of part, saves the resource of precious metal material to greatest extent, and according to measuring and calculating, the lumber recovery of metal material is increased to 62.5%～79%.Through high temperature, high-potting, instrument all satisfies the well logging instructions for use in many-sided checkings such as actual logging operations.
Description of drawings:
Fig. 1 oil well logging instrument bearing shell structural representation.
1 fittings body, 2 housing main bodies, 3 external screw threads, interface on 4 loggers, 5 internal threads, 6 logger lower interfaces,
The specific embodiment:
Oil well logging instrument bearing shell described in the utility model is made of fittings body 1 and 2 two parts of housing main body; Fittings body 1 one ends are provided with external screw thread 3, housing main body 2 is provided with internal thread 5 with fittings body 1 a corresponding end, be welded as a whole after fittings body 1 and housing main body 2 thread connection, fittings body 1 other end is connected with interface 4 on the logger, interface 4 outer walls are provided with outer connecting thread on the logger, the other end of housing main body 2 is connected with logger lower interface 6, and logger lower interface 6 inwalls are provided with interior connecting thread.
