Ese uzi neza RTTS packer?

Paki ya RTTS:

Ibisobanuro by'ingenzi RTTSipakir ni icyuma kinini gipakira gifite ubushobozi bwo kwihanganira igitutu cy’impande zombi. Cyagenewe by’umwihariko gukora imirimo myinshi mu bikorwa nko gupima imiterere y’ikintu, gushyira aside mu kirere, no gukamura sima, bigatuma imirimo itandukanye irangizwa mu rugendo rumwe. Bityo, gikoreshwa cyane mu gihe cyo gukora igerageza. Gusobanukirwa neza imiterere yacyo imbere bifasha gukemura neza ibibazo bishobora kuvuka mu gihe cyo gukora no kubungabunga.

1. Ibisobanuro bya RTTS Packer

Ipaki ya RTTS ni ipaki ikoreshwa mu buryo bwa tekiniki, ifite igikoresho cyo gufunga amazi. Ikoreshwa cyane cyane mu gutandukanya uturere no gushyiramo aside, kandi ishobora no gukoreshwa mu bikorwa byo gupima amariba, gutera amazi, no gukamura sima. Ipaki ya RTTS ni igikoresho cyihariye gikoreshwa mu gutandukanya uturere twa peteroli, gazi n'amazi turi mu gisanduku. Yishingikiriza ku mbaraga zo hanze kugira ngo ikandagire igice cya rubber, ikagabanya uburebure bwayo kandi yongere umurambararo wayo kugira ngo ifunge agace kari hagati y'umuyoboro n'igisanduku. Ibi bitandukanya uturere turi hejuru no munsi y'igisanduku, bigatuma kiba cyiza mu gupima amavuta na gazi. Ingano zisanzwe zirimo 4½″, 5″, 5½″, 7″, na 9⅝″. Buri ngano ifite uburyo bwo guhindura J-slot, slips za mechanical, igikoresho cyo gupakira, n'imiterere ya hydraulic anchor. Ipaki ya hydraulic ibuza izamuka ry'ipaki iyo igitutu kiri munsi yayo kiri hejuru cyane. Iki kintu gituma igikoresho kiba cyiza cyane mu gupima mu byobo bidahuje. Imiterere ya paki ijyanye n'ingano zitandukanye z'igisanduku, byoroshya ibikorwa mu byobo bitandukanye.

2. Imiterere y'imiterere

Igipfunyika kigizwe n'icyuma gifunga amazi, ikintu gipfunyikamo amabati, uduce duto duto, n'uduce duto two gushyira hamwe, hamwe n'ibindi bice.

3. Ibiranga

a) Inkingi ya hydraulic ikoreshwa n'umuvuduko w'imiyoboro, bikarinda neza ko ipakiye izamuka.
b) Uduce duto dutandukanywa n'agace ko gukurura kandi tugakandagirwa mu gace k'inyuma iyo upakira utari mu mwanya uhamye.
c) Uburyo bwa J-slot bwikora butuma byoroha gushyiraho.
d) Ifata ry'umukandara rikozwe mu buryo bwa "casing collar grip" rifite "tungsten carbide inserts" hamwe n'uburyo bwa "hydraulic anchor" bworohereza imiterere myiza y'ipaki.

4. Ibigomba kwitabwaho mu mikorere

a) Mbere yo gukoresha icyo gipakira, icyo cyobo kigomba kuzunguzwa neza kandi kigasukurwa kugira ngo hatagira imyanda ibuza ibidukikije cyangwa kubikuramo.
b) Uburyo bwo gushyiraho ibintu bugomba gukorwa neza kandi buhoro. Guhagarara byihutirwa bigomba kwirindwa kugira ngo hirindwe ko ibintu bihinduka mu buryo butunguranye.
c) Ubujyakuzimu bw'aho imashini ishyirwa bugomba kwirinda ko ifata imigozi.
d) Iyo agapaki katarekuye mu gihe cyo kugakuramo, umugozi ugomba guterurwa no kumanurwa inshuro nyinshi kugeza ku burebure bw'aho kajugunywa kugira ngo kakuremo utubuto twa tungsten carbide mbere yo gukurura.

5. Ibyiza bya RTTS Packer

RTTS packer ni kimwe mu bikoresho bikoreshwa cyane mu gupima amariba. Ikwiriye cyane cyane amariba afite umuvuduko muke, adapfa kwinjira mu mazi ndetse n'amariba afite amavuta menshi (amariba adapfa amazi) yangiritse cyane mu gihe cyo gucukura, gutera sima, cyangwa ibindi bikorwa. Ayo mariba akunze kugira igihombo gikomeye, bisaba igihe kirekire cyo kugerageza no gusubira inyuma inshuro nyinshi kugira ngo haboneke ibipimo nyabyo by'amazi n'imiterere yayo.

RTTS packer ifasha ibikorwa bitandukanye bihuriweho, harimo:
Ikizamini cya TCP (Tubing Conveyed Perforating) + MFE (Multi-Flow Evaluator)

Isuzuma rya TCP + MFE + JET (hydraulic pump discharge)

Ibikorwa bya TCP + MFE + JET + gutera aside

Iyi RTTS packer iroroshye kuyikoresha, ihendutse, igabanya cyane ikiguzi cyo kuyikoresha, kandi itanga inyungu zikomeye mu bukungu no mu mibereho myiza y'abaturage.

Ipaki ya RTTS ni ipaki yuzuye, ikoreshwa mu gupima, kuvura no gukamura sima. Kenshi na kenshi, ikoreshwa hamwe n'itsinda ry'imashini zizunguruka. Ipaki igizwe na J-slot mechansim, imashini zizunguruka, ikintu cyo gupakira, n'imashini zizunguruka. Imashini nini kandi ziremereye ziri mu ifunga rya hydraulic lock zifasha gukumira ko igikoresho kivanwa mu mwobo. Ku mashini zizunguruka ≤ 3½″ (88.9 mm), imashini ikurura ikoresha uburyo bwa J-slot, mu gihe imashini zikurura zikoreshwa ku ngano ≥ 4″ (101.6 mm). Imashini zose zizunguruka zifite agakoresho ka J-slot nk'uko bisanzwe. Iyo hakoreshejwe valve izunguruka, iba yo mu bwoko bwa lock-open/lock-close kandi ikora nka valve izunguruka na bypass. Iyo packer ishyizweho, valve ihita ifunga mu mwanya wayo. Mu gihe cyo kugerageza cyangwa gukamura sima, ifunga ibuza valve gufunguka. Agace ka J gahagaze neza mu mwanya wo gufungura gahuye n'agace ka J gahagaze neza mu gice cyo gupakira (ni ngombwa). Uku guhuza bikuraho gukenera kuzunguruka umuyoboro kugira ngo ufunge valve izenguruka cyangwa kongera gushyiramo agapaki nyuma yo kwimura sima.

Ibiranga:

Imiterere yuzuye ya packer mandrel ituma amazi menshi anyura muri icyo gikoresho. Imbunda zitwarwa n'imiyoboro n'ibindi bikoresho by'insinga bishobora kunyura muri packer.

Agapaki gashobora gushyirwaho no gusubizwaho inshuro nyinshi binyuze mu gukoresha imiyoboro y'amazi mu buryo bworoshye.

Utwuma twa tungsten carbide dutanga uburyo bwo gufata no kudashira neza, cyane cyane mu gasanduku gakomeye. Uburyo bwo gufunga hydraulic bukorwa hakoreshejwe imbaraga zinyuzwa mu muyoboro.

Valve ikoreshwa mu gupima ifunze cyangwa ifunze mu gihe cyo gupima, ishobora gufungurwa byoroshye iyo bikenewe kugira ngo igere hejuru y'agapaki.

Imikorere:

Kugira ngo ushyireho agapaki, shyira igikoresho munsi gato y'ubujyakuzimu bw'aho gishyirwa, hanyuma uzamure kandi uzunguruke inshuro nyinshi. Niba igikoresho kiri hasi, ni ngombwa ko uzunguruke igice cy'inyuma gusa. Ariko, mu byobo birebire cyangwa byacitse, hashobora kuba ngombwa ko uzunguruke inshuro nyinshi ukoresheje igikoresho kizunguruka. Kugira ngo ukomeze aho uhagaze, imbaraga zo gufunga iburyo zigomba gufatwa kugeza igihe imiyoboro y'amashanyarazi ishyizwe kandi uburemere bugashyirwa. Hakenewe imbaraga zihagije ku mpande zombi z'agapaki kugira ngo ufungure agapaki. Mu gihe ukurura umuyoboro, valve izenguruka ikomeza gufunga, bigatuma uzenguruka inyuma munsi y'agapaki. Kugira ngo ufungure valve izenguruka kugira ngo iriba rihinduke, umanure umuyoboro, uzunguruke iburyo, kandi uzamure.
Uburyo bwo gushyiraho no gusohora RTTS Packer

Hagarika agapaki hanyuma wimure agakoresho ko gukurura hejuru no hasi inshuro nyinshi kugira ngo urebe ko utunyuzi twa mekanike tugenda mbere yo kwinjira mu mwobo.

Mbere yo kwinjira, funga valve izenguruka aho ifunguye; J-slot igomba kandi kuba ifunze aho umugozi ufatanye n'agace ka J-slot hook hanyuma uduce dusubira inyuma,
Mu gihe cy’uko imashini ikora, imashini irazamuka, ishyiraho uburyo bwo gusimbuka no gufunga valve izenguruka. Kugira ngo wirinde ko valve ifunga ku buryo butunguranye, gabanya umugozi, zunguruka iburyo, uzamuke ugere aho ufunguye, hanyuma uzunguruke ibumoso kugira ngo ufunguke—witondere kudakuramo umuyoboro.

Iyo igikoresho kigeze ku burebure bw'intego yo kugerageza, gimanure gato munsi y'ubujyakuzimu bw'intego, hanyuma uzamuke ugere aho gishyirwa.

Mu ruziga, zunguza umugozi w'umuyoboro inshuro nyinshi iburyo—ubusanzwe igice cy'uruziga gusa ni cyo gikenewe ku gikoresho.

Komeza imbaraga z'iburyo kandi ushyireho uburemere ku miterere y'icyuma.

Hagarika kumanura umugozi, zunguruka ibumoso, hanyuma urekure imbaraga z'iburyo. Muri rusange, kimwe cya kabiri cy'izunguruka kuri metero 300 kirahagije; nturenze umubare w'ingufu z'iburyo zakoreshejwe mu gihe cyo gushyiraho.

Ukoresheje imbaraga z'iburyo, shyira umugozi ku gipakira kugira ngo ushyireho imbaraga wifuza zo gushyiraho.

Kugira ngo ufungure valve izenguruka kandi ukomeze kugenzura ikigega, zunguza umugozi iburyo hanyuma uzamuke; shyira igitutu hejuru y'umuyoboro hanyuma ukomeze kuzamura kugeza igihe umuvuduko w'amazi ugeze. Fata uyu mwanya, pompa amazi, hanyuma ureke kugeza umuvuduko uvuye amaraso, ureke igikoresho gifate uburemere. Hindura ibumoso kugira ngo urekure imbaraga, hanyuma ukomeze kugabanya uburemere kugeza igihe igipakira gishyizwemo imbaraga zikenewe.

Kugira ngo usoze ikizamini kandi urekure agapaki, banza ushyire igitutu ku gapaki, hanyuma ukure umugozi udahindukiye kugira ngo valve izenguruka ikomeze gufunga hanyuma ushyireho uruziga rw'inyuma ruzengurutse agapaki.

Manura umuyoboro, zunguza umugozi, hanyuma uzamuke kugira ngo ufungure valve izenguruka. Icyo gikoresho gishobora gukurwa mu mwobo.
