Integrated multifunctional skid for heating, separating, buffering and loading of photo-thermal well fluid

Abstract

The invention discloses an integrated multifunctional skid for heating, separating, buffering and loading of photo-thermal well fluid. The integrated multifunctional skid comprises an oil-gas separation buffer; the oil-gas separation buffer is connected with a well fluid wellhead pipeline, a crude oil outlet pipeline, a gas phase backflow pipeline and a liquid separation bag; the liquid separation bag is externally connected with a natural gas outlet pipeline; a heat exchange coil pipe is arranged in the oil-gas separation buffer; and a circulating hot water inlet pipeline is arranged at one end of the heat exchange coil pipe, and a circulating hot water outlet pipeline is arranged at the other end of the heat exchange coil pipe. Compared with the prior art, the integrated multifunctional skid has the beneficial effects that facilities such as a well site raw water jacket heating furnace, an oil-gas separator, natural gas drying gas and an elevated oil tank are replaced, light energy is fully utilized for heating crude oil, the technological process is simplified, and separation, heating and closed loading of the well fluid are achieved through one skid.

Description

technical field [0001] The invention relates to the field of well fluid treatment equipment, in particular to a photothermal well fluid heating, separation, buffering and loading integrated multifunctional skid. Background technique [0002] At present, oil production well sites with high content of associated gas are generally equipped with facilities such as water jacket heating furnace, oil and gas separator, natural gas drying gas, and elevated oil tank. Water jacket furnaces often use wellhead associated gas to heat well fluids; in order to ensure the temperature of crude oil during pipeline transportation or tanker transportation, as oil storage facilities commonly used in well sites, elevated oil tanks generally use electric heating rods to heat crude oil. Heating, high energy consumption, short service life. At the same time, the elevated oil tank loading process is non-airtight, and there is a certain amount of VOCS emission, which pollutes the environment. Conte...
