Abstract
The utility model discloses a receiving transducer part structure, which relates to the field of petroleum logging, and comprises a receiving transducer body, wherein a plurality of groups of receiving transducer bodies externally sleeved with metal sound-transmitting covers are respectively installed on receiving transducer mandrels to form a plurality of receiving transducer components, adjacent receiving transducer bodies are fixedly connected through pan head screws, adjacent receiving transducer mandrels are connected through metal corrugated pipes in a welding way, grooves are formed on the receiving transducer mandrels and used for being clamped into nylon sleeves and fixed by hexagon socket head screws, and the connection between adjacent receiving transducer components is realized; and a lead is arranged in the mandrel of the receiving transducer to realize the electric connection between adjacent receiving transducer bodies. Compared with the conventional receiving transducer structure, the structure of the capsule is changed into an all-metal structure, so that the corrosion resistance of the instrument is improved; separating the metal portion of the receiving transducer assembly from the metal portion of the inner bore of the slotted housing of the acoustic system greatly reduces the noise transmitted by the slotted housing.
Description
Technical Field
The utility model relates to an oil well logging field, concretely relates to receive transducer part structure.
Background
Acoustic logging tools are one of the important tools for logging systems in the petroleum industry. The functions of measuring the longitudinal wave of the formation of the open hole well, measuring the full wave train of the formation of the open hole well, checking the cementing quality of the cased hole well and the like can be realized. The receiving part of the acoustic probe is used for receiving acoustic signals transmitted from the stratum, is an important component of the acoustic logging instrument, and is used for processing and converting the signals received by the receiving transducer in the receiving acoustic system into analog signals or digital signals which are provided for a ground instrument for processing. The conventional receiving transducer structure generally adopts a structure that a capsule is sleeved outside a transducer or a metal sound-transmitting cover is sleeved outside the transducer, and the transducers are connected by a soft metal corrugated pipe for sound insulation treatment.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art existence, and provide a receive transducer part structure, have the advantage that the measurement is accurate, the result is reliable, corrosion resistance is strong.
The purpose of the utility model is accomplished through following technical scheme: the receiving transducer part structure comprises a receiving transducer body, wherein a plurality of groups of receiving transducer bodies externally sleeved with metal sound-transmitting covers are respectively arranged on receiving transducer mandrels to form a plurality of receiving transducer assemblies, adjacent receiving transducer bodies are connected and fixed through pan head screws, adjacent receiving transducer mandrels are welded and connected through metal corrugated pipes, grooves are formed in the receiving transducer mandrels and used for clamping nylon sleeves and fixing the nylon sleeves through inner hexagon screws, and connection between adjacent receiving transducer assemblies is achieved; and a lead is arranged in the receiving transducer mandrel to realize the electric connection between adjacent receiving transducer bodies.
The utility model has the advantages that: compared with the conventional receiving transducer structure, the structure of the capsule is changed into an all-metal structure, so that the corrosion resistance of the instrument is improved, and the instrument is more attractive; the nylon sleeve is added, so that the very soft metal corrugated pipe is protected, the internal tension and pressure are transmitted to the nylon sleeve, the assembly and the maintenance are convenient, and the reliability of the instrument is improved; separating the metal portion of the receiving transducer assembly from the metal portion of the inner bore of the slotted housing of the acoustic system greatly reduces the noise transmitted by the slotted housing.
