Abstract
The invention discloses a convenient-to-clean petroleum sieve pipe auxiliary device, which mainly solves the problems that the existing wire-wrapped sieve pipe can be easily damaged or generate seam deformation in the use process, so that the well completion quality and the sand-proof effect are lowered, or failure occurs. The convenient-to-clean petroleum sieve pipe auxiliary device consists of an input pipeline (1), two filtering devices (2) and an output pipeline (3) which are in sequential connection. The convenient-to-clean petroleum sieve pipe auxiliary device is characterized in that a three-way valve (4) is connected with a petroleum outlet end of the input pipeline (1); the petroleum inlet end of the output pipeline (3) is connected with a three-way pipeline (5); and the two filtering devices are detachably connected between the three-way valve (4) and the three-way pipeline (5). The convenient-to-clean petroleum sieve pipe auxiliary device has the advantages that the sand content in the petroleum is reduced; the petroleum suction filtering effect is not influenced; meanwhile, the cost is low; and the cleaning is convenient, and the like.
Description
Technical field
The present invention relates to a kind of Petroleum screen tube servicing unit, what be specifically related to is the Petroleum screen tube servicing unit being convenient to clear up.
Background technology
The Main Function of Petroleum screen tube is exactly sand prevention, and because recover petroleum makes the geology residing for oil well, the grade of steel of the pipe that sand bed difference adopts is different with kind.
In petroleum drilling and mining operation, screen casing is a kind of important equipment, often adopts completion or oil extraction sand prevention in advance.At present, more screen casing is used to be wire-wrapped screen.The manufacture method of this screen casing is: around being uniformly distributed in, being wound around the steel wire in certain cross section on sieve bar or on the metal liner of perforate and welding, and reserving certain gap as sieve aperture.Although this manufacture method is used by numerous producer at home, but there are some problems when going into the well in this screen casing, especially when suppressing the curved segment by high angle hole or horizontal well, inevitably collide with the borehole wall or sleeve pipe, extrude and rub, easily there is sleave phenomenon, cause screen damage or gap distortion, cause total completion time and sand controlling result reduce or lost efficacy.
For this drawback of wire-wrapped screen, invent a kind of servicing unit, can filter the husky body in oil further, reduce the sand content in oil.
Summary of the invention
The object of the invention is to solve existing wire-wrapped screen in use easily damage or gap distortion, the problem causing total completion time and sand controlling result to reduce or lost efficacy, provides a kind of and reduces oil sand content, do not affect oil suction filtration effect, cost is low and be convenient to the Petroleum screen tube servicing unit cleared up simultaneously.
For solving above-mentioned shortcoming, technical scheme of the present invention is as follows:
Be convenient to the Petroleum screen tube servicing unit cleared up, be made up of the input channel connected in turn, filter and output channel, the oil export end of described input channel is connected with a three-way valve, and the oil arrival end of output channel is connected with a three-way pipeline; Described filter is two, and it is removably connected between three-way valve and three-way pipeline.
The use of filter in the present invention, the husky body remained in oil after effectively can filtering out Petroleum screen tube screening, reduces the sand factor in oil; Simultaneously, this filter is two, can the filter of transform filter in time after coordinating with three-way valve and three-way pipeline, and then under filtering in filter during rockier body, more can facilitate replacing or the cleaning of filter, thus not affect the suction filtration effect of oil.
Further, described filter comprises filter chamber, to be set in parallel in filter chamber and filter chamber to be separated into the screen pack of two or more chamber, with the entrance of one of them chamber, and with the outlet of another chamber.
In order to reach filter effect best, described screen pack is fixed in filter chamber by sealing joint strip.
As preferably set-up mode, described screen pack is two, and filter chamber is separated into three chambers by from left to right, and entrance is positioned at above right chamber, and outlet is then positioned at below left chamber.
In order to filtration situation can be understood in time, and in time filter replaced and clear up, the outlet of described filter is also provided with electromagnetic flowmeter.
The present invention compared with prior art, has the following advantages and beneficial effect:
1, the use of filter in the present invention, effectively can filter out husky body residual in oil after Petroleum screen tube screening, reduce the sand factor in oil;
2, in the present invention, filter is set to two, the filter for filtering can be converted in time after coordinating with three-way valve and three-way pipeline, and then when remaining rockier body in filter, more can facilitate replacing or the cleaning of filter, thus do not affect the suction filtration effect of oil;
3, the setting of electromagnetic flowmeter in the present invention, can understand the filtration situation of filter PetroChina Company Limited. in time, and can replace filter in time and clear up;
4, structure of the present invention simple, with low cost, be convenient to cleaning and change, and it does not affect the suction filtration effect of oil, is applicable to very much applying.
