The present invention belongs to the field of dynamic oil well monitoring method. The leakage diagnosing method for oil production well with ground driven screw pump includes the following steps: first collecting relevant production data and calculating the lower torque limit and lower axial force limit of the polished rod; testing to draw three curves of polished rod torque, axial force and well head oil pipe pressure in the process from starting through normal production to stopping of the oil production well with screw pump; and judging whether to have system leakage and further judging pump leakage or oil pipe leakage based on certain conditions. The method can obtain determined result and is favorable to further proper operation measures in high operation efficiency.
