Level measurement in oil well production

The above theory is based on the fluid is homogeneous density, but the actual production is divided into the early low water cut period of oil Wells, aqueous medium and high water cut period, the early and mid moisture content less than 50% ~ 60%, more than 60% for high water-cut stage. Before mid, the well fluid is water-in-oil phenomenon, namely the crude oil is a liquid is the continuous phase, the output water for which phase separation. Under this situation, free water does not occur. Exists in the form of emulsion liquid, can think in this period the well produced fluid is uniform density of liquid, close to the above theory.

the fluid at the high water-cut stage, the well flow after entering the separator, free water precipitation in the bottom of the separator, the separator at the bottom of the water will be the main factors influencing the moisture content of calculation accuracy. The emergence of the bottom water means between the two thermometer installation height reduction, namely the H3 narrow. In theory of H3 narrowed, directly affect the value of H4. When the bottom water covered all the H3, Pfn magnetic flap | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer

H4 disappear, namely two thermometer at the same height, moisture content is 100%. However, floating in the upper part of the separator of crude oil is still there. At this point the water analysis will lose its significance. Magnetic flap Pfn | | glass thermometer thermometer floating ball | | glass thermometer thermometer two-color thermometer
