Abstract

The invention relates to the field of oil exploitation, and particularly discloses a water injection well mouth water sound transmitting and receiving device which comprises an active sensor, an intelligent water distributor, an upper connector, an upper outer sleeve, a conversion connector, a lower outer sleeve and a lower connector which are arranged at the working end in a water injection well, water passing holes are formed in the upper connector and the lower connector, and an eccentric through hole is formed in the conversion connector and connected with an inner sleeve. The inner sleeve is connected with a circuit board fixing frame, the circuit board fixing frame is connected with a circuit control board, a plurality of circuits used for processing signals are arranged in the circuit control board, the bottom of the conversion connector is detachably connected with an underwater acoustic transducer, the upper connector on one side of the circuit control board is provided with a cable channel, and an AC / DC module is arranged outside the cable channel of the upper connector. The lower connector is provided with a water injection channel and an acoustic channel, the underwater acoustic transducer is electrically connected with the circuit control board, the underwater acoustic transducer carries out underwater acoustic communication with the active sensor through water, and the problem that a wellhead communication signal of a traditional water injection well is unstable can be effectively solved.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a wellhead hydroacoustic transceiver of a water injection well. Background technique [0002] After the oil field is put into development, with the increase of the production time, the pressure of the oil layer will continue to drop, resulting in a significant reduction in the production of the oil well, and even stop the injection and production. At this time, in order to make up for the underground deficit caused by the extraction of crude oil, maintain and increase the pressure of the oil layer to achieve In order to achieve high and stable production in oilfields, layered water injection must be carried out in oil layers. Layered water injection is a technical measure to implement water injection through the isolation of packers and the control of water nozzles, so that high, medium and low permeability formations can play the role of water injection, so as to adjust the contr...
