Abstract: This application relates to the field of oil and gas devices, systems, and methods, and particularly relates to a packing leakage detection system and method. The packing leakage detection system includes a plunger pump, a pressure sensor and a control system, where the pressure sensor is configured to detect a pressure value inside a hydraulic end of the plunger pump, and send the detected pressure value to the control system; and the control system is configured to acquire the pressure value sent by the pressure sensor, and send prompt information according to the pressure value, where the prompt information includes at least one of alarm information and information for prompting shutdown and overhaul. This application is used for solving the problem that a leakage anomaly caused by a packing failure is not discovered in time.

Abstract: A fracturing manifold skid and a fracturing manifold skid set are provided. The fracturing manifold skid includes a skid base assembly and a first manifold assembly. The first manifold assembly is installed on the skid base assembly and includes a first transport pipe and a second transport pipe, and a first connecting pipe and a second connecting pipe. The first connecting pipe is connected with the first transport pipe at a first position and connected with the second transport pipe at a second position; the second connecting pipe is connected with the first transport pipe at a third position and connected with the second transport pipe at a fourth position. The first transport pipe is provided with a first valve located between the first and third positions; the second transport pipe is provided with a second valve located between the second and fourth positions.
