Description
Technical field
The utility model is related to oil exploration equipment technical field, specifically a kind of pipeline is sustained high-efficiency antiscaling device.
Background technology
There are mainly two types of reasons for dirt formation in the equipment such as oil extraction pipeline：First, containing the easy scaling salt of high concentration in water flooding
Ion, in oil recovery process, because pressure, temperature or water constituent variation change original chemical balance due to generate dirt, mainly with
Based on calcium carbonate scale, it is in addition also mixed with magnesium carbonate, calcium sulfate/magnesium etc..Second is that two or more incompatible water is blended in
Together, scale-forming ion interacts and generates dirt.
Antiscale is using the either physically or chemically crystallization of control dirt, nuclei growth and deposition before dirty brilliant formation, mainly
Means have：(1) it prevents germination or inhibits crystal growth；(2) nucleus is detached, scaling cations, mainly chelating divalent are controlled
Metal ion；(3) it prevents from depositing, solid phase particles is kept to spread in water and prevents from depositing in metal surface.
Oilfield produced fluid fouling is a kind of deposit of compact structure, and dirt will dispose incrustation and need with a large amount of once being formed
Scale remover and construction equipment, input cost is high and cannot eradicate fouling, injury of the scale removal to pit shaft tubing and casing and surface line
It is larger；And be then of relatively low cost using antiscale means, select Low Damage scale preventative to stratum, tubing and casing and surface line not
It will produce injury.
