Water injection well mouth pressure measurement device

The utility model provides a water injection well mouth pressure measurement device. The water injection well mouth pressure measurement device comprises an oil pipe connector used for being connected with an oil production tree water injection well testing gate. An electronic pressure gauge is inserted into the oil pipe connector. A plurality of water passing holes are formed in the position where the lower end of the oil pipe connector makes contact with the electronic pressure gauge. A communication plug interface is designed on the electronic pressure gauge. An interface hole for containing the communication plug interface is formed in the oil pipe connector. The whole water injection well mouth pressure measurement device is arranged on the oil production tree water injection well testing gate to unceasingly monitor and store the pressure and the temperature, and the data playback and the continuous real-time monitoring can be achieved in the test process.
