Abstract
The utility model discloses a high-speed self-cleaning fine seam filtering mechanism, which belongs to the technical field of oilfield comprehensive development, comprising a cylindrical stainless steel filtering cover; single-edge curve fine seams or double-edge curve fine seams are distributed on the filtering cover. The edge of the fine seam is a curve, and the curve equation is similar to the Archimedean spiral equation. The utility model has the advantages of self-cleaning function, stable filtering precision and high filtering efficiency, can lighten the erosion of the carried sand on the mechanical critical parts, prolongs the service life, and is used for filtering the oil gas in the oilfield exploration.
Description
Affiliated technical field
The utility model relates to filter mechanism, and especially hydrocarbon filter mechanism belongs to synthetical development technology field, oil field.
Background technology
At present, the filter mechanism of using in the oilfield exploitation has laser slotted mechanism, take-up mechanism, punching press vertical masonry joint mechanism etc., the effect that it can play sand control to a certain extent and improve oil field comprehensive development efficient.But exist not enough at anticorrosion, filter efficiency, filtering accuracy stability, self-cleaning ability, the anti-aspect such as sand erosion of taking.
The utility model content
At the problems referred to above, the utility model provides high speed self-cleaning slit filter mechanism.
The technical scheme that its technical problem that solves the utility model adopts is:
The self-cleaning slit filter mechanism of high speed comprises cylindrical stainless steel filter mantle, is distributed with monolateral curve slit on the filter mantle, and the edge line of slit is a curve, and its curvilinear equation and Archimedes spiral equation are approaching.
The self-cleaning slit filter mechanism of high speed comprises cylindrical stainless steel filter mantle, is distributed with bilateral curve slit on the filter mantle, and the edge line of slit is a curve, and its curvilinear equation and Archimedes spiral equation are approaching.
The beneficial effects of the utility model are, the tool self-cleaning function, filtering accuracy is stable, filter efficiency is high, can alleviate take sand to the erosion at mechanical key position, prolong its application life.Being used for oilfield exploitation filters oil gas.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
As Fig. 1-4, the self-cleaning slit filter mechanism of high speed comprises cylindrical stainless steel filter mantle 1, is distributed with monolateral curve slit 2 on the filter mantle 1, and the edge line of slit is a curve, and its curvilinear equation and Archimedes spiral equation are approaching.
As Fig. 5-8, the self-cleaning slit filter mechanism of high speed comprises cylindrical stainless steel filter mantle 1, is distributed with bilateral curve slit 3 on the filter mantle 1, and the edge line of slit is a curve, and its curvilinear equation and Archimedes spiral equation are approaching.
Monolateral or bilateral curve slit is can be largely balanced and subtract the primary oil flow edge drag, increases effective filtration area, thereby improves filter efficiency; Also can take sand simultaneously and provide one along one of the curve tangential direction very little power to oily stream, make and take sand and flow away along slit, to avoid impacting frequently, energetically even block seam to the curve slit, in a word, this mechanism can be balanced and subtracts the primary oil flow edge drag, possess self-cleaning function and guarantee stable filtering accuracy, also can avoid taking the erosion of sand, thereby prolong the working life of filter mantle key position.
