Abstract

The invention provides an indoor testing device and method for testing a production well resistivity instrument. The indoor testing device comprises a ground system, a cable simulator, a metal sleeve, a resistance simulation device, a pump speed regulator and an artificial resistance pool, wherein the ground system is electrically connected with the production well resistivity instrument through the cable simulator; the production well resistivity instrument is located in the metal sleeve; the metal sleeve is located in the resistance simulation device; one end of the resistance simulation device is connected with one end of the artificial resistance pool through the pump speed regulator and the other end of the resistance simulation device is connected with the other end of the artificial resistance pool; the pump speed regulator is connected with the ground system through a lead. When being used for testing the production well resistivity instrument, the indoor testing device is flexible to operate, small in floor space and capable of satisfying the indoor testing requirements.

Description

technical field [0001] The invention relates to the technical field of oil and gas resources and environment development, in particular to an indoor experimental device and method for testing a production well resistivity instrument. Background technique [0002] In the development of oil and gas resource environment, in order to extract oil and natural gas, it is usually necessary to drill wells, which are called production wells. Production wells in a broad sense also include water injection wells, gas injection wells, observation wells, etc. drilled for the development of oil and gas fields. The physical parameters of the formation can be obtained by logging using the electrochemical properties and electrical conductivity of the rock formation, so as to provide reference for oil and gas development. The resistivity instrument of the production well is a commonly used logging device. Different from general instruments, testing production well resistivity instruments requi...
