Description
Foreliggende oppfinnelse angår en kabel for mating av boresonder i olje- og gassbrønner. The present invention relates to a cable for feeding drill probes in oil and gas wells.
En kabel av denne art må ha minst mulig diameter for lett å kunne passere gjennom borehullet og tillate oppspoling av store kabellengder på kabeltromler. Videre må den være i stand til å motstå betraktelig påkjenning av tre forskjellige typer, nemlig mekanisk påkjenning på grunn av oljetrykk som kan gå opp til 350 bar eller mer, varierende kjemiske påkjenninger alt etter arten av den foreliggende oljesubstans, samt termiske påkjenninger ved temperaturer som kan nå opp til eller overskride 150°C. A cable of this nature must have the smallest possible diameter to be able to easily pass through the borehole and allow the winding of large cable lengths on cable drums. Furthermore, it must be able to withstand considerable stress of three different types, namely mechanical stress due to oil pressure which can go up to 350 bar or more, varying chemical stress according to the nature of the oil substance present, as well as thermal stress at temperatures which can reach up to or exceed 150°C.
En kabel av denne art er særlig kjent fra britisk patentskrift 2.027.553 og omfatter en midtre elektrisk leder samt to forsterkningselementer på hver sin diamametralt motsatte side av denne, og som alle tre er innkapslet i et flatt elastomerhylster. Denne kabel opptar liten plass på grunn av elasto-merhylsterets flate form, samt har god klemstyrke takket være de to sidestilte forsterkningselementer. Den gir imidlertid ingen god ytre beskyttelse mot slagpåkjenninger e.l. og heller ikke god beskyttelse mot høye temperaturer nede i borehullet. A cable of this type is particularly known from British patent document 2,027,553 and comprises a central electrical conductor and two reinforcement elements on each diametrically opposite side of this, and all three of which are encased in a flat elastomer sleeve. This cable takes up little space due to the flat shape of the elastomer sheath, and has good clamping strength thanks to the two side-by-side reinforcement elements. However, it does not provide good external protection against impact stresses etc. nor good protection against high temperatures down the borehole.
Det er derfor et formål for foreliggende oppfinnelse å sikre en god ytre beskyttelse ved å forsyne elastomerhylsteret med en metallarmering samt god temperaturbestandighet ved an-vendelse av uroganisk isolasjonsmaterial for den midtre leder-kabel. It is therefore an aim of the present invention to ensure good external protection by providing the elastomer casing with a metal reinforcement as well as good temperature resistance by using inorganic insulation material for the central conductor cable.
Oppfinnelsen gjelder således en matekabel for boresonder i olje- og gassbrønner og som består av en midtre elektrisk leder samt to sidestilte forsterkningselementer, idet lederen og de to forsterkningselementer er innkapslet i et flatt elastomerhylster. The invention thus relates to a feed cable for drill probes in oil and gas wells and which consists of a central electrical conductor and two side-by-side reinforcement elements, the conductor and the two reinforcement elements being encased in a flat elastomer sleeve.
På denne bakgrunn av kjent teknikk har da matekabelen i henhold til oppfinnelsen som særtrekk at nevnte elektriske leder omfatter en elektrisk ledende tråd, et lag av uorganisk isolasjon samt et ytre overtrekk, mens elastomerhylsteret er dekket av en fleksibel ytre armeringskappe av metall. On this background of known technology, the feed cable according to the invention has as a distinctive feature that said electrical conductor comprises an electrically conductive wire, a layer of inorganic insulation and an outer cover, while the elastomer sheath is covered by a flexible outer metal armor sheath.
En kabel i henhold til oppfinnelsen vil nå bli nærmere be-skrevet under henvisning til de vedføyde tegninger, hvorpå: A cable according to the invention will now be described in more detail with reference to the attached drawings, after which:
Fig. 1 viser kabelen med alle dens bestanddeler, og Fig. 1 shows the cable with all its components, and
Fig. 2 viser et tverrsnitt av samme kabel langs linjen Fig. 2 shows a cross-section of the same cable along the line
II-II i fig. 1. II-II in fig. 1.
I fig. 1 er det vist at foreliggende kabel består av en midtleder 10 som omfatter en sentral kobbertråd 11, en uorganisk isolasjon 12 av magnesiumoksyd, samt et overtrekk 13 av rust-fritt stål. Hver av de to forsterkningselementer 20 består av tvinnede ståltråder, mens et hylster 30 av syntetisk elas-tomermaterialer omslutter midtlederen og de to forsterkningselementer og er forsynt med en ytre armering 40 av "Interlock"-type. In fig. 1 it is shown that the present cable consists of a central conductor 10 which comprises a central copper wire 11, an inorganic insulation 12 of magnesium oxide, and a covering 13 of stainless steel. Each of the two reinforcement elements 20 consists of twisted steel wires, while a sleeve 30 of synthetic elastomer materials encloses the central conductor and the two reinforcement elements and is provided with an external reinforcement 40 of the "Interlock" type.
Den ytre armering 40 er utført som en enkelt metallstrimmel 41 viklet i skrueform om kabelhylsteret med overlappende strim-melkanter. The outer reinforcement 40 is made as a single metal strip 41 wound in a screw shape around the cable sleeve with overlapping strip edges.
De to forsterkningselementer 20 er tvunnet eller slått i innbyrdes motsatt retning for å motvirke vridning og unngå floking av kabelen. The two reinforcement elements 20 are twisted or twisted in mutually opposite directions to counteract twisting and avoid tangling of the cable.
Fig. 2 viser klart kabelens flate tverrsnittsform samt det forhold at ytterdiameteren av forsterkningselementene er større enn midtlederens diameter for å gi beskyttelse mot innklemning av kabelen. Fig. 2 clearly shows the flat cross-sectional shape of the cable as well as the fact that the outer diameter of the reinforcement elements is larger than the diameter of the central conductor to provide protection against pinching of the cable.
