Description
Technical field
The utility model relates to polishing filter technical field, particularly a kind of oil field resistance to erosion filter.
Background technology
The filter of current oil field at home water filling mainly contains quartz filter, walnut shell filter, fiber ball filter and a small amount of fiber bundle filter.Wherein quartz filter be a kind of quartz sand that adopts as the filter of filler, although to have filtration resistance little for it, specific area is large, resistance to acids and bases is strong, the advantages such as resistance tocrocking is good, but it is not high to sewage disposal precision, is difficult to reach the requirement of water injection in low-permeability oilfield water quality index; Walnut shell filter take walnut shell as filter medium, because this walnut shell as filter medium entered specially treated, so it is large to have surface area, high adsorption capacity, the advantage that clearance is high, but also there is the not high problem with being difficult to reach the requirement of water injection in low-permeability oilfield water quality index to sewage disposal precision in it; Fiber ball filter is a kind of filter adopting fiber-ball filter media, the fiber of this fibrous nodules is made by the special fibre silk synthesized through new chemical formulation, fiber filtering is changed into hydrophilic by lipophilic by the modification that its main feature is through essence, filtrate diameter can reach tens microns even several microns, there is specific area large, the advantages such as filtration resistance is little, also solve the filtering accuracy of particulate filter by problems such as particle diameter of filter medium restrictions simultaneously.It is the renewal product of the granular filter material such as quartz sand and walnut shell filter plant.
In above-mentioned, existing fiber ball filter also exists following defect: in metre filter process, often ignore the impact of filtrate to baffle plate, this can have influence on the job stability of elevating motor, make elevating motor be in the duty of vibration for a long time, cause elevating motor easily to break down and reduction of service life; When filtering oil-field flooding, usually containing various dregs in water, shape size differs, as some filiforms, bulky grain thing, when these dregs are transported in filter packing, although can be filtered filler to filter out, in follow-up cleaning process, pole is not easy to wash, particularly filiform, its meeting and filter packing are intertwined, and cause being separated, at this moment just have to change filter packing and again fill in new filter packing, this is a kind of larger waste in resource and cost, does not meet the green production standard of national regulation.
Utility model content
Goal of the invention of the present utility model is: for above-mentioned Problems existing, a kind of oil field resistance to erosion filter is provided, by arranging a filter screen, the impact of filtrate to baffle plate can be reduced on the one hand, make elevating motor work more steady, on the other hand can filiform in filter liquor and bulky grain thing, filter packing is more easily cleaned, reduces the use amount of filter packing.
