Abstract
The invention relates to a countercurrent high-pressure-injection emulsion breaker filling device. The countercurrent high-pressure-injection emulsion breaker filling device comprises a storage tank (1), a feeding port (2), an air outlet hole (3), a measuring pump (4), a filling pipe (5) and a main pipeline (7). The countercurrent high-pressure-injection emulsion breaker filling device is simple in structure, reasonable in design and convenient to operate. When an emulsion breaker is filled in a countercurrent high-pressure injection way, the defects that the emulsion breaking time is short and the mixing is non-uniform can be overcome, and the emulsion breaking effect can be improved; and drastic turbulent flow can ensure that the emulsion breaker is uniformly mixed with crude oil emulsion, so that the emulsion breaker can rapidly reach an oil-water interface, and the stability of the emulsion can be broken.
Description
Technical field
The present invention relates to a kind of adverse current high pressure spraying emulsion splitter filling apparatus.
Background technology
At present oil field emulsion splitter dosing method commonly used has: instillation technology, injection injection technology etc., these traditional filling technology filling points are arranged on the branch pipe tee connection position more, some in addition directly inject from pressure gauge connection.The emulsion splitter following current that the total characteristics of these injection modes are exactly flow in pipes is flowed with crude oil emulsion, and there are characteristics such as the viscosity high-density is big in present domestic most crude oil, in pipeline, flow and all be laminar flow respectively, this has just caused the emulsion splitter of filling and crude oil emulsion evenly to mix very difficult, if the filling technology after without equipment shear histories such as vigorous agitation or pumps, emulsion splitter is difficult to evenly reach oil-water interfacial film, thereby had a strong impact on the crude oil demulsification dehydration effect, it is big to cause many oil fields all to exist emulsion splitter to add dosage, demulsification is poor, and emulsion splitter is changed difficult problems such as frequent.By discovering when emulsion splitter injects in adverse current high pressure spraying mode, can remedy the inhomogeneous shortcoming of short mixing of breakdown of emulsion time, improve demulsification, mainly due to violent turbulent flow emulsion splitter and crude oil emulsion are evenly mixed, make emulsion splitter reach water-oil interface fast, destroy the stability of milk sap.
Present domestic crude oil extraction majority is heavy crude, and the water content height adds that various chemical displacement of reservoir oil The Application of Technology make output crude oil emulsion emulsification degree height, multiple milk sap coexistence, breakdown of emulsion difficulty.The high-density of viscous crude and high viscosity make that adding breakdown of emulsion is difficult to evenly be mixed into the oil-water interfacial film surface, even there is high-efficient demulsifier also not reach good breaking emulsion and dewatering effect, and then it is big to cause emulsion splitter to add dosage, and production cost improves.
Existing emulsion splitter charging method:
(1) " well head adds agent, breakdown of emulsion in the pipe " namely at well head emulsion splitter is added collector tubing, along with crude oil emulsion flows ducted, promote the mixing of emulsion splitter and milk sap.Mainly be to mix apart from improving mixed effect by increasing, oil sample high viscosity high density viscous crude mostly is laminar flow distribution in pipeline, and the emulsion splitter that this mode adds and milk sap mixed effect are undesirable.
(2) filling emulsion splitter before the lift pump, this mode mainly is the mixing that promotes emulsion splitter and milk sap by the high speed shear of pump, because the emulsion splitter with the concurrent filling before pump mainly is distributed in pipeline filling position one side, even be difficult to also guarantee that by the shearing of pump itself and milk sap evenly mix.Emulsion splitter generally mostly is high molecular polymer simultaneously, the branched structure complexity, and side chain is more, and the too high emulsion splitter molecular structure that might cause of pump shearing rate destroys, and then influences demulsification.
Emulsion splitter dosing method at present commonly used is difficult to guarantee that emulsion splitter and milk sap evenly mix, simultaneously present the most frequently used " well head adds agent; breakdown of emulsion in the pipe " mode, need one cover emulsion splitter filling apparatus be set at every mouthful of oil well, and it is inapplicable for the abortion gauging field of drawing oil with car, certain limitation is arranged, filling cost height.
The filling emulsion splitter needing to be mainly used in the occasion of supercharging before dehydration before the pump, otherwise need increase equipment such as pump in technical process, both uneconomically can not guarantee to improve demulsification.
