Bolt support control production zone identification method
An identification method and rod string technology, which are used in earth-moving drilling, production of fluids, wellbore/well components, etc., can solve the problem of inability to intuitively judge the situation of layer changes on the spot, the inability to realize the situation of downhole switch layer changes, and the inability to realize layer changes. It can achieve the effect of facilitating transportation and on-site operation, improving the reliability of layer changing, and simplifying the structure of the construction pipe string.
