n: the number of centigrams of bromine that are absorbed by 1 gram of oil under certain conditions. This is a test for the degree of unsaturatedness of a given oil.

n: A kind of method measuring degree of unsaturation of bromine. It is a target of choosing oil of oil base drilling fluid.

a viscosimenter use for some fluid measurements, particularly when solid suspension properties are needed.

n: a metal cap, mounted on a tray, that has openings allowing vapour bubbles in a gas-processing tower to contact cool liquids, causing some of the vapour to condense to liquid.

n: A kind of brassboard method for controlling gas overflowing. When gas overflowing leading to underground blowout happens, an actuator will be threw into the drill column to open side opening of diverter valve.

n: 1. the temperature and pressure at which part of a liquid begins to convert to gas. For example, if a certain volume of liquid is held at constant pressure, but its temperature is increased, a point is reached when bubbles of gas be- gin to form in the liquid. That is the bubble point. Similarly, if a certain volume of liquid is held at a constant temperature but the pressure is reduced, the point at which gas begins to form is the bubble point. Compare dew point. 2. the temperature and pressure at which gas, held in solution in crude oil, breaks out of solution as free gas.

the pressure at which gas begins to break out of an under saturated oil and form a free gas phase in the matrix or a gas cap.

n: a vertical cylindrical vessel in which bubble caps and bubble-cap trays are arranged.

n: a perforated steel tray on which bubble caps are mounted. Bubble caps and trays are arranged in bubble towers, cylindrical vessels set vertically. See sieve tray. valve tray.

n: The inferior drill column bend since bit load produced by self-weight reach to definite value when drill column is in the wellbore. It is decided by bit load and deviation angle.
