Experimental Study of Wax Precipitation in Gas Condensate with High Temperature, High Pressure and High Wax

Abstract

Abstract: The study of wax precipitation in gas condensate with high temperature, high pressure and high wax from Tarim basin indicates that the phase behavior of such a gas condensate is extremely complex under different temperatures and pressures, showing gas, liquid, gas-liquid, gas-solid and gas-liquid-solid phases. The pressure has a distinct influence on the temperature of the wax precipitation: when the pressure is high, the influence is not clear; when it is close to dew point pressure, the temperature goes up with the drawdown of pressure; when it is lower than dew point pressure, it goes down with the decrease of pressure.

Key words: gas condensate, phase state, wax precipitation, temperature
