An oil and water well ground all-purpose tester relates to an oil and water well testing device for oil field production, characterizing in that it comprises a host machine, a pressure sensing device, an electric flow transducer, a screw pump sensing device, a pumping unit sensing device and liquid level gun. A microprocessor, an interface circuit, a wireless data receiving circuit, a liquid level front end circuit, a keyboard display circuit and a power circuit are equipped on the board of the host machine, and a keyboard, a display and various sensing device interfaces are equipped on the outer shell of the host machine. This utility model is provided with the benefits that it realizes the synchronic efficiency-related parameter testing of the three major system of a pump well, a screw pump well, a water perfusion well applying one instrument. This utility is provided with precise measurement data, safety, strong operation capacity and convenient data input into the computer without bringing computers on site. It is easy to carry due to its low cost, convenient portability, small cubage and only one kilogram or so weight, and thereby being suitable for field operation of the oil wells and testing of the commercial wells in the oil fields.
