Description
Technical field
The present invention relates to ageing oil in oil filed processing technology fields, more particularly to a kind of ageing oil in oil filed inorganic agent.
Background technique
Ageing oil in oil filed refers to that the accumulation time is long, the reluctant sump oil of prior art means.Since ageing oil contains perhaps
The mechanical admixtures such as the stronger clay of more electric conductivity and FES, these substances often will cause dewatering system purification oil it is aqueous exceeded or
Sewage quality is exceeded after de-, while these impurity are very fine crushing, it is not easy to settle, after being largely flocked on grease transition zone, make oil
Water termination is smudgy, and under the action of electric field, causes electric dehydrator short circuit to be tripped, or even break electric field, seriously affects just
Often production；Especially oil recovery technique is quickly grown in recent years, and various chemistry increase oily measure and occupy the very big component of oil recovery technique, although
Chemistry increases oil and improves yield, but also brings very big negative effect, and the aging oil ingredient for producing generation is more complicated, in addition to
Have the conventional substances such as petroleum hydrocarbon, colloid, asphalitine, wax, solid particle, inorganic salts and bacterium, there are also containing polymer, alkali,
Transfer drive surfactant etc., ageing oil processing cost are continuously increased.In addition, country payes attention to environmental protection, wanting for ageing oil is recycled
It asks and is also increasingly stringenter, therefore how efficient, economy processing ageing oil is the severe challenge that oil field faces.
Aging oil processing at present mainly passes through the means such as sedimentation, filtering and is handled, and is then recycled to oil treatment system, with
Enter electro-dewatering apparatus after fresh crude oil blending, droplets form is made under the action of electric field, power is then relied on for support and is isolated from oil
Come.
Summary of the invention
The present invention for solve technical problem present in well-known technique provide it is a kind of have component is simple, it is convenient to prepare,
Rapidly and efficiently, the ageing oil in oil filed inorganic agent of the features such as low in cost, wide application, high-efficient, usage amount is small demulsification.
