Abstract
The utility model discloses a cascading petroleum pipeline filtering device which comprises a multi-level filtering inner core and a single-level filtering inner core, wherein the outer part of the multi-level filtering inner core is provided with an upper-level filtering pipe section and is communicated with a lower-level filtering pipe section at the outer part of the single-level filtering inner core through the pipe section; three mesh type filtering strips are vertically arranged in the multi-level filtering inner core; a filtering tank is mounted above the inside of the single-level filtering inner core; and a layer of filtering screen is additionally arranged at each port at the junction between the upper-level filtering pipe section and the lower-level filtering pipe section. The device disclosed by the utility model has the beneficial effects that a cascading dual-core structure is used for filtering, and filtering structures are vertically and horizontally arranged in the two inner cores respectively; meanwhile, a filtering structure is additionally arranged at the junction between the outer pipe sections of the two inner cores to realize running type filtration; and the device has the advantages of reasonable structure, convenience, practicability, strong filtering effect, layered filtration of petroleum, convenient using conditions and the like.
Description
Technical field
The utility model relates to technical field of petroleum extraction, relates in particular to a kind of concatenation type petroleum pipeline filter.
Background technology
At present, the pipe fitting that is applied to the industries such as oil, chemical industry, electric power, boats and ships, metallurgy, machinery, weaving, food, building, pharmacy all needs to possess higher intensity, resistance to pressure, corrosion-resistant, resistance to elevated temperatures, therefore, in technical field of petroleum extraction, in order to improve the recovery ratio of crude oil, usually will carry out secondary oil recovery and tertiary oil recovery, screen casing is installed on oil well bottom, a kind of special tubes that the oil that is used for exploiting out separates with the sandstone on stratum.But present Petroleum screen tube structure is too simple, generally at tubing table wall processing strip or poroid screen casing, also some screen casing is to adopt stainless steel wire to be wound around after punching to make screen casing, and clearly, its filtering function is relatively poor, can't layering filter, can not satisfy industrial requirement; In addition, present screen casing function is too single, can only carry out the sieving operation, but can't carry out normal transportation work, can't satisfy people's demand, and heat insulation effect is not good enough, not corrosion-resistant, service life is short.Therefore, for above aspect, need to make rational improvement.
The utility model content
But the purpose of this utility model is to provide, and a kind of series connection structure is reasonable, convenient and practical, the concatenation type petroleum pipeline filter of the strong layered filtration oil of filter effect, the service condition that facilitates, to solve many deficiencies of prior art.
The purpose of this utility model is come specific implementation by the following technical programs:
A kind of concatenation type petroleum pipeline filter, comprise multistage filtering inner core, single-stage filtration inner core, described multistage filtering inner core outer setting higher level filters pipeline section and is communicated with by subordinate's filtration pipeline section that this pipeline section and single-stage are filtered the inner core outside, multistage filtering inner core internal vertical wherein arranges three road mesh-type filter bags, wherein single-stage is filtered the inner core inner and upper lautertuns is installed, and is positioned at the higher level and filters pipeline section and set up respectively one deck screen pack with subordinate filtration pipeline section joining place port separately.
Be positioned at the interface outer setting sealing ring that the higher level filters pipeline section and subordinate's filtration pipeline section joining place, described single-stage is filtered one section flowline of the outside connection of inner core.
The beneficial effect of concatenation type petroleum pipeline filter described in the utility model is: filter by the concatenation type twin-core structure is set, two interior core inners respectively vertical, be horizontally disposed with filtration, simultaneously, set up again filtration at the outside pipeline section joining place of two inner cores, realize the purpose that continuous-flow type filters, but possessed the advantages such as rational in infrastructure, convenient and practical, the strong layered filtration oil of filter effect, the service condition that facilitates; During use, by these different filtrations, can make the sandstone in fluid filter clean.
Description of drawings
The below is described in further detail the utility model according to drawings and embodiments.
Fig. 1 is the structure chart of the described concatenation type petroleum pipeline of the utility model embodiment filter.
In figure: 1, multistage filtering inner core; 2, single-stage is filtered inner core; 3, screen pack; 4, sealing ring; 5, mesh-type filter bag; 6, the higher level filters pipeline section; 7, pipeline section filters in subordinate; 8, lautertuns; 9, flowline.
The specific embodiment
As shown in Figure 1, the described concatenation type petroleum pipeline of the utility model embodiment filter, comprise multistage filtering inner core 1, single-stage filtration inner core 2, described multistage filtering inner core 1 outer setting higher level filters pipeline section 6 and filters inner core 2 outside subordinate by this pipeline section and single-stage and filter pipeline section 7 and is communicated with, is connected in series connection thereby filter inner cores with two; Multistage filtering inner core 1 internal vertical wherein arranges three road mesh-type filter bags 5, single-stage is wherein filtered inner core 2 inner and upper lautertuns 8 is installed, be positioned at the higher level and filter pipeline section 6 and filter pipeline section 7 joining places port separately with subordinate and set up respectively one deck screen pack 3, be positioned at the higher level and filter the interface outer setting sealing ring 4 that pipeline section 7 joining places filter in pipeline section 6 and subordinate; Simultaneously, described single-stage is filtered one section flowline 9 of the outside connection of inner core.
Claims (3)
1. a concatenation type petroleum pipeline filter, comprise multistage filtering inner core, single-stage filtration inner core, it is characterized in that:
Described multistage filtering inner core outer setting higher level filters pipeline section and is communicated with by subordinate's filtration pipeline section that this pipeline section and single-stage are filtered the inner core outside, multistage filtering inner core internal vertical wherein arranges three road mesh-type filter bags, wherein single-stage is filtered the inner core inner and upper lautertuns is installed, and is positioned at the higher level and filters pipeline section and set up respectively one deck screen pack with subordinate filtration pipeline section joining place port separately.
2. a kind of concatenation type petroleum pipeline filter as claimed in claim 1, is characterized in that: be positioned at the interface outer setting sealing ring that the higher level filters pipeline section and subordinate's filtration pipeline section joining place.
3. a kind of concatenation type petroleum pipeline filter as claimed in claim 1, is characterized in that: one section flowline of the outside connection of described single-stage filtration inner core.
