High-frequency signal sensing device for monitoring sand production in oil and gas wells

The utility model relates to a high-frequency signal sensing device for monitoring sand production in oil and gas wells, which is characterized by comprising an oil inlet pipeline and an oil return pipeline. The oil inlet pipeline and the oil return pipeline are arranged in parallel on an oil-gas production pipeline of an oil and gas well, and axially perpendicular to the oil-gas production pipeline, a metering pump is arranged on the oil inlet pipeline, a pressure sensor is further arranged on the oil return pipeline, an oil monitoring pipeline is communicated between the oil inlet pipeline and the oil return pipeline, a signal sensing diaphragm is arranged between the oil monitoring pipeline and the oil return pipeline., and a high-frequency signal sensor is tightly adhered to the signal sensing diaphragm. The high-frequency signal sensing device is applicable to the field of oil and gas well development projects.
