Abstract
The recognition of fluid-filled channels in cased holes is significant for the safety production of oil and gas wells. The fluid-filled channel at the cement-formation boundary is more difficult to be detected than that at the casing-cement boundary. To solve the key technical problem, a dual-frequency acoustic measurement method is proposed to obtain the cementation state of the two interfaces at the same time. The related theory is that the...
