Three-phase well test apparatus using pumped recirculation to maintain homogenous flow |
摘要 |
A three-phase well test apparatus and method using a two-phase separator. A separator is used to separate well fluid into gas and liquid constituents. The gas constituent is measured by a gas flow meter, and a pressure control valve is used to prevent surging of the gas beyond the range of the meter A pump is used to pump liquid out of the separator through a liquid flow line. A recirculating line is provided, and a valve may be acutated between a flow position and a recirculating position in response to a liquid level in the separator. When liquid is not being flowed for measurement, it is recirculated to the separator and thereby continuously mixed to maintain the liquid in a homogeneous condition. Downstream from the valve is a liquid meter and a meter prover connection. The recirculation mixes the liquid A mixer may be positioned downstream from the pump to additionally mix the liquid flowing therethrough. A back pressure valve is positioned in the liquid flow line to keep an adequate back pressure on the meter.
