Die Drainageschicht ist mit Leitringen fixiert. Die Filtersiebe und der fixierende Draht sind mit Leitringen befestigt. Die Leitringe bestehen aus einem Stahlblechband. Am Anfang und am Ende eines Filterschlitzelements sind Abstandsringe angeordnet.The drainage layer is fixed with guide rings. The filter screens and the fixing wire are attached with guide rings. The guide rings consist of a steel strip. At the beginning and at the end of a filter slot element spacer rings are arranged.
Mängel dieses Filters sind eine niedrige Zuverlässigkeit und ein schneller Verschleiß des Filterelements.Shortcomings of this filter are low reliability and rapid wear of the filter element.

Die vorliegende Erfindung hat sich zur Aufgabe gestellt, die Stabilität eines Bohrlochfilters zu erhöhen, den Verschleiß dieses Filters zu vermindern und die Versorgung eines notwendigen Filtrierungsniveaus im Laufe einer längeren Zeit zu gewährleisten.The object of the present invention is to increase the stability of a wellbore filter, to reduce the wear of this filter and to ensure the supply of a necessary filtration level over a longer period of time.
Diese Aufgaben werden dadurch gelöst, dass der Drahtbohrlochfilter, der ein perforiertes Rohr und ein filtrierendes Schlitzelement umfasst, das aus einem Draht besteht, der auf in Rohrlängsrichtung verlaufende Elemente spiralförmig aufgewickelt ist, wobei der Querschnitt eines spiralförmig aufgewickelten Drahts fünfflächig ausgebildet ist, eine der Drahtflächen parallel zur Filterlängsachse verläuft und die Außenfläche des Filters bildet und wobei jeder Seitenrand mit zwei Flächen versehen ist; dabei bilden die oberen Seitenflächen einen filtrierenden Spielraum, während die unteren Seitenflächen aufeinander zulaufen und einen spitzen Winkel bilden. Die oberen Flächen stehen senkrecht zur Filterlängsachse und parallel zu den oberen Flächen der benachbarten Windungen.These objects are achieved in that the wire borehole filter comprising a perforated tube and a filtering slit member made of a wire spirally wound on members extending in the tube longitudinal direction, wherein the cross section of a spirally wound wire is formed five-fold, one of the wire surfaces extends parallel to the filter longitudinal axis and forms the outer surface of the filter and wherein each side edge is provided with two surfaces; The upper side surfaces form a filtering clearance, while the lower side surfaces converge and form an acute angle. The upper surfaces are perpendicular to the filter longitudinal axis and parallel to the upper surfaces of the adjacent turns.
Der Neigungswinkel einer querlaufenden Achse der oberen Flächen ist geringer als der der unteren Flächen. Die Stoßstellen der unteren sind abgerundet. Die Perforation im Rohrmittelteil ist durch Öffnungen gebildet. Die Öffnungen der Perforation im Rohrmittelteil sind durch abgeschnittene Pfropfen verschlossen. Die Perforation im Rohrmittelteil kann durch Schlitze längs des Rohrs gebildet sein. Die Perforation im Rohrmittelteil kann auch durch Schlitze gebildet sein, die quer über das Rohr verlaufen. Die Perforation im Rohrmittelteil kann auch durch Schlitze gebildet sein, die schräg zur Rohrlängsachse verlaufen. Am Anfang und am Ende eines filtrierenden Schlitzelements sind Abstandsringe angeordnet. Auf dem perforierten Rohr können zwei filtrierende Elemente angeordnet sein, von denen jedes durch Abstandsringe befestigt ist.The inclination angle of a transverse axis of the upper surfaces is less than that of the lower surfaces. The joints of the lower are rounded. The perforation in the middle part of the pipe is formed by openings. The openings of the perforation in the middle part of the tube are closed by cut-off plugs. The perforation in the middle part of the pipe can be formed by slots along the pipe. The perforation in the pipe middle part can also be formed by slots which extend across the pipe. The perforation in the middle part of the pipe can also be formed by slots which run obliquely to the tube longitudinal axis. At the beginning and at the end of a filtering slit element spacer rings are arranged. On the perforated tube two filtering elements can be arranged, each of which is fixed by spacer rings.
Die vorliegende Erfindung verfügt über Neuheit und industrielle Anwendbarkeit, d. h. über alle Kriterien einer Erfindung. Die Neuheit dieser Erfindung wird von durchgeführten Patentforschungen bestätigt. Die industrielle Anwendbarkeit ist dadurch bedingt, dass bei der Herstellung eines Drahtbohrlochfilters nichtdefizitäre Stoffe und bekannte Technologien verwendet werden.The present invention has novelty and industrial applicability, i. H. about all criteria of an invention. The novelty of this invention is confirmed by patent researches. The industrial applicability is due to the fact that in the manufacture of a wire borehole filter non-deficient substances and known technologies are used.
Die Erfindung wird nun anhand von Ausführungsbeispielen, die in den folgenden
In den
Die oberen Ränder
Der Drahtbohrlochfilter arbeitet folgendermaßen:
Abgesonderte Drahtbohrlochfilter werden in einer Kolonne auf Futterrohren oder im Bestand einer Aufhängung eines Stützankers gesammelt und in einem Produktionshorizont eingefahren. Beim Vorhandensein der abgeschnittenen Pfropfen
Separate wire borehole filters are collected in a column on casings or in the inventory of a suspension of a support anchor and retracted in a production horizon. In the presence of cut-off stoppers
Die Verwendung der Erfindung hat erlaubt:
- 1. Die Zuverlässigkeit und Haltbarkeit des Filters zu erhöhen,
- 2. im Laufe einer langen Zeit ein notwendiges Filtrierungsniveau zu gewährleisten,
- 3. eine Erdgas- und Erdölfiltrierung von mechanischen Beimischungen zu gewährleisten und
- 4. die Stabilität des filtrierenden Elements in Bezug auf den Schleifverschleiß zu erhöhen.
- 1. To increase the reliability and durability of the filter
- 2. to ensure a necessary level of filtration over a long period of time,
- 3. to ensure natural gas and oil filtration of mechanical admixtures and
- 4. to increase the stability of the filtering element with respect to grinding wear.
