Well-bore Mud-leak Survey Instrument for Drilling Engineering

摘要

According to the demand for measuring the mud leak of well bore, a new method for determining the position of leak stratum was proposed. The method was based on surveying the flow velocity of the mud fluid, temperature and pressure under the well. According to the oil field circumstance, a storage style well-bore mud-leak survey instrument scheme was introduced. And the corresponding hardware and software were developed, the measured parameters and interpretation results can be displayed in the form of curve and diagram after processing, which showed the precise position of the leak stratum.
