Abstract

The invention discloses a serial connection type petroleum pipeline filtering device. The serial connection type petroleum pipeline filtering device comprises a multi-grade filtering inner core and a single-grade filtering inner core, wherein the outer part of the multi-grade filtering inner core is provided with an upper-grade filtering pipe section and is communicated with a low-grade filtering pipe section at the outer part of the single-grade filtering inner core through the pipe section; the inner part of the multi-grade filtering inner core is internally and vertically provided with three paths of net hole type filtering nets; a filtering groove is formed above the inner part of the single-grade filtering inner core; a layer of a filtering net is respectively and additionally arranged in each one of respective end ports of the engaged part of the upper-grade filtering pipe section and the low-grade filtering pipe section. The serial connection type petroleum pipeline filtering device disclosed by the invention has the beneficial effects that a serial connection type double-core structure is arranged to filter and filtering structures are respectively vertically and horizontally arranged inside the two inner cores; meanwhile, a filtering structure is additionally arranged at the engaged part of outer part pipe sections of the two inner cores, so that the aim of running water form filtering is realized; the serial connection type petroleum pipeline filtering device has the advantages of reasonable structure, convenience and practicability, strong filtering effect and the like, and is capable of filtering petroleum by layers and capable of providing convenient use conditions.

Description

A kind of concatenation type petroleum pipeline filter

Technical field

The present invention relates to technical field of petroleum extraction, relate in particular to a kind of concatenation type petroleum pipeline filter.

Background technology

At present, the pipe fitting that is applied to 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, is used for a kind of special tubing that the oil that exploitation is come out is separated 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 twine 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 sieving operation, but can't carry out normal transportation work, can't satisfy people's demand, heat insulation effect is not good enough, not corrosion-resistant, service life short.Therefore, at above aspect, need make rational improvement.

Summary of the invention

But the purpose of this invention is to provide that 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.

Purpose of the present invention 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 filters pipeline section by the subordinate of this pipeline section and single-stage filtration inner core outside and is communicated with, 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 one deck screen pack respectively 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 of the present invention is: filter by the concatenation type twin-core structure is set, two inner core inside respectively vertical, be horizontally disposed with filtration, simultaneously, set up filtration again at the outside pipeline section joining place of two inner cores, realize the purpose that continuous-flow type filters, but possessed 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 the fluid filter clean.

Description of drawings

The present invention is described in further detail with embodiment with reference to the accompanying drawings below.

Fig. 1 is the structure chart of the described concatenation type petroleum pipeline of embodiment of the invention filter.

Among the 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 embodiment of the invention 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 subordinates filtration pipeline sections 7 by this pipeline section and single-stage and is communicated with, and connects thereby filter the inner cores serial connection 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 one deck screen pack 3 respectively, 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

1. a concatenation type petroleum pipeline filter comprises multistage filtering inner core, single-stage filtration inner core, it is characterized in that:
