Gas-invaded mud flows through the inlet, strikes the impact plate, and disperses over internal baffles. This collision and exposed surface area create turbulent flow, separating the gas from the drilling fluid. The gas outlet at the top of the tank discharges free gas. A technician determines and configures the exhaust line length on-site. The degassed drilling fluid flows through a shale shaker and into a circulation tank.
Gas-laden mud ejected from the well flows through the manifold of the choke manifold and enters the cyclone flow in the upper portion of the separator assembly. Sedimentation is the primary separation of some gas and liquid. The mud flows through the separator plates, where it is dispersed into a thin layer, exposing bubbles on their surface. This further separates the gas from the mud. The separator discharges the separated gas from its top through an exhaust pipe to a desired location. Clean mud falls to the bottom of the separator, and a drain pipe returns it to the mud tank.
A centrally mounted liquid level mechanism controls the air supply to the pneumatic butterfly valve. This mechanically controlled valve maintains a constant liquid level, regulates mud discharge through the drain pipe, and prevents aerated mud from flowing directly into the mud tank.
The liquid level control mechanism consists of a float, a pressure regulating valve, a reversing valve, and a connecting rod piston rod. When the liquid level in the separator reaches a certain level, the float rises under buoyancy, driving the connecting rod (the piston rod) to push the reversing valve. Gas enters the pneumatic butterfly valve, opening it and discharging the liquid from the separator. When the liquid level in the separator drops to a certain level, the connecting rod (the piston rod) retracts, reversing the reversing valve and closing the pneumatic butterfly valve, stopping the discharge.
The main functions of the poorboy degassers
The main functions of the poor boy oil and gas are: 1. It serves as the suction port for oil and gas to enter the multi-stage centrifugal pump; 2. Before the mixed gas enters the multi-stage centrifugal pump, the separator separates free gas from the well fluid. This reduces the impact of gas on the operating characteristics of the submersible electric pump, prevents cavitation and gas lock, and ensures the normal operation of the multi-stage centrifugal pump. The gas-oil separator is a device that separates crude oil and associated natural gas produced by the oil well. Placed between the submersible centrifugal pump and the protector, the separator separates free gas from the well fluid, delivering liquid to the submersible centrifugal pump while releasing gas into the annular space between the tubing and casing.
Position the separator on the ground adjacent to the No. 1 circulating tank near the shale shaker. Anchor the unit to the ground using wire ropes attached to the four upper lifting lugs. Mount the ignition chamber and ignition device directly at the exhaust line outlet.
Inspect the lower buffer plate before each use. If wear exceeds 10 mm, replace both plates before returning to service.
After each use, the drilling crew should drain the drilling fluid from the separator (especially in winter to prevent the tank from freezing and cracking) and open and clean the cleaning port or inlet.
