The utility model discloses a decentralized wellhead casing pressure is surveyed and is got device belongs to the mechanical technical field of oil field oil recovery. The survey is got the device and is included plug, pressure meter connector and manometer, the plug is used for being connected with the test valve of decentralized wellhead, is equipped with the through -hole that is used for intercommunication test valve on it, be equipped with the through -hole on the pressure meter connector, pressure meter connector is connected with the plug, pressure meter connector's through -hole and the through -hole of plug intercommunication, the manometer is connected with pressure meter connector. Can test the valve with the decentralized wellhead through the plug is connected for this survey is got the device and is dismantled the convenience, and the casing pressure to eccentric well that can be very fast is surveyed and is got, device simple structure, size little, light in weight, portable and loading and unloading are got in this survey.
