Oil Well Production Analyzing System

摘要

An oil well production analyzing system receives production fluid samples from the oil well according to an automated sampling schedule. The fluid samples are received within a degassing cylinder and separated into a liquid phase and a gas phase, with the liquid phase automatically transferred to a sampling cylinder for water cut analysis. Once the liquid phase has been transferred to the sampling cylinder, a piston within the degassing cylinder automatically evacuates all fluid from the cylinder in preparation of receiving a subsequent fluid sample from the oil well.

主权项

1. A system for ascertaining a relative percentage of water contained in a liquid phase of a fluid sample received from a well, where the fluid sample comprises the liquid phase and a gas phase, and the liquid phase comprises oil and water, the system comprising:
a fluid inlet from the well through which the fluid sample is received, a fluid outlet through which the fluid sample is discharged, and a vessel disposed between the fluid inlet and the fluid outlet; the vessel comprising a degassing cylinder wherein the degassing cylinder receives at least a portion of the fluid sample from the fluid inlet; a piston disposed within the degassing cylinder wherein the piston is moveable from a first position to a second position, wherein substantially all of the liquid phase of the fluid sample received by the degassing cylinder is transferred outside of the degassing cylinder as the piston moves from the first position to the second position; and a first sensor connected to the degassing cylinder which ascertains when the piston is in the first position and a second sensor which ascertains when the piston is in the second position.
