I-RTTS packer ivumela imisebenzi eyahlukeneyo edibeneyo, kuquka:
Uvavanyo lwe-TCP (iTubing Conveyed Perforating) + i-MFE (iMulti-Flow Evaluator)

Uvavanyo lwe-TCP + MFE + JET (hydraulic pump discharge)

Imisebenzi ye-TCP + MFE + JET + ukwenza i-asidi

I-RTTS packer kulula ukuyisebenzisa, ixabisa kancinci, inciphisa kakhulu iindleko zokusebenza, kwaye inika iingenelo ezinamandla kwezoqoqosho nakwezentlalo.

I-RTTS packer yi-full-bore, suspended packer esetyenziselwa uvavanyo, unyango, kunye nemisebenzi yokucinezela i-cement. Kwiimeko ezininzi, isebenza kunye ne-circulating valve assembly. Umzimba we-packer uquka i-J-slot mechansim, ii-mechanical slips, i-packing element, kunye nee-hydraulic slips. Ii-slips ezinkulu nezinzima kwi-hydraulic lock zinceda ukuthintela ukuba ifom yesixhobo ipompelwe emngxunyeni. Kwi-packer bodies ≤ 3½″ (88.9 mm), i-drag spring isebenzisa i-J-slot mechanism, ngelixa ii-drag blocks zisetyenziswa ngobukhulu ≥ 4″ (101.6 mm). Zonke ii-packer bodies zixhotyiswe nge-automatic J-slot sleeve njengesiqhelo. Ukuba kusetyenziswa i-circulating valve, iluhlobo lwe-lock-open/lock-close kwaye isebenza njenge-circulating kunye ne-bypass valve. Xa i-packer isetiwe, i-valve iyazitshixa ngokuzenzekelayo kwindawo evaliweyo. Ngexesha lokuvavanya okanye ukucinezela i-cement, i-lock ithintela i-valve ekubeni ipompelwe ivuleke. I-J-slot ethe tye kwindawo evulekileyo yokutshixa ifana ne-J-slot ethe tye emzimbeni we-packer (ukhetho). Olu dibaniso lususa isidingo sokujikeleza ityhubhu ukuvala ivalvu ejikelezayo okanye ukuseta kwakhona i-packer emva kokususa isamente.

Iimbonakalo:

Uyilo olupheleleyo lwe-packer mandrel luvumela ukuba kufakwe ulwelo olukhulu kwisixhobo. Izibhamu ezithuthwa ngetyhubhu kunye nezinye izixhobo zentambo zinokusetyenziswa kwi-packer.

Ipakethi ingamiselwa kwaye imiselwe kwakhona amaxesha amaninzi ngokusebenzisa ulawulo olulula lwetyhubhu.

Ii-tungsten carbide inserts zibonelela ngokubamba okuphuculweyo kunye nokumelana nokuguguleka, ingakumbi kwi-casing enamandla aphezulu. Indlela yokutshixa i-hydraulic iyasebenza ngokusebenzisa uxinzelelo ngetyhubhu.

Ivalvu ejikelezayo edibeneyo ekhethiweyo itshixa kwindawo evulekileyo okanye evaliweyo ngexesha lovavanyo lokucinezela kwaye ingavulwa lula xa kufuneka ukuvumela ukuhambahamba ngaphezulu kwepakethi.

Umsebenzi:

Ukuze usete ipakethi, yehlisa isixhobo kancinci ngaphantsi kobunzulu obufunekayo bokuseta, uze uphakamise kwaye ujikelezise izihlandlo ezininzi. Ukuba isixhobo sisezantsi, kufuneka isiqingatha sokujika kuphela. Nangona kunjalo, kwimingxuma enzulu okanye ephambukileyo, kufuneka ujikelezise izihlandlo ezininzi kusetyenziswa isixhobo esijikelezayo. Ukuze ugcine indawo, i-torque yesandla sasekunene kufuneka ibanjwe de kube kubekwe izilayidi zoomatshini kwaye ubunzima bunokusetyenziswa. Uxinzelelo olulinganiselayo kumacala omabini epakethi luyafuneka ukuze kukhululwe ipakethi. Xa utsala ityhubhu, ivalvu ejikelezayo ihlala ivaliwe, ivumela ukujikeleza okungasemva ngaphantsi kwepakethi. Ukuvula ivalvu ejikelezayo ukuze kufudukelwe umthombo, yehlisa ityhubhu, jikelezisa uye ngasekunene, kwaye uphakamise.
Indlela Yokuseta Nokukhulula I-RTTS Packer

Xhoma ipakethi uze uhambise isikhongozeli sebhloko yokutsala phezulu nasezantsi amaxesha amaninzi ukuze ujonge ukuhambahamba kwezilayidi zoomatshini ngaphambi kokuba ungene emngxunyeni.

Ngaphambi kokuba ungene, vala ivalvu ejikelezayo kwindawo evulekileyo; i-J-slot nayo kufuneka ibe kwindawo etshixiweyo kunye ne-lug ebambeke kwindawo ye-J-slot hook kwaye iziliphu zibuyiselwe umva,
Ngelixa ingena, indlela yokutsala ityibilika iye phezulu, ibeka izilayidi zoomatshini kwaye ivale ivalvu ejikelezayo. Ukuthintela ukuvalwa kwevalvu ngengozi, yehlisa umtya, ujikelezise ngasekunene, unyuse uye kwindawo evulekileyo, uze ujikelezise ngasekhohlo ukuze uyivale—uqaphele ukuba ungayikhululi ityhubhu.

Xa isixhobo sifikelela kubunzulu obujoliswe kubo ukuze kuvavanywe, sehlise kancinci ngaphantsi kobunzulu bokuseta, uze unyuse uye kwindawo yokuseta.

Umgodi wokuhla, jika umtya wetyhubhu ujike kaninzi uye ngasekunene—ngesiqhelo kufuneka isiqingatha sokujika kuphela kwisixhobo.

Gcina i-torque yesandla sasekunene kwaye ubeke ubunzima kwii-mechanical slips.

Yeka ukuthoba umtya, jikelezisa ngasekhohlo, uze ukhulule i-torque yesandla sasekunene. Ngokubanzi, isiqingatha sokujika kwi-300 yeemitha sanele; ungadluli kwinani lokujika kwesandla sasekunene elisetyenzisiweyo ngexesha lokuseta.

Xa usebenzisa i-torque yasekunene, yehlisa intambo kwi-packer ukuze usebenzise amandla okuseta afunekayo.

Ukuze uvule ivalvu ejikelezayo kwaye ugcine ulawulo lomngxuma, jikelezisa intambo ngasekunene uze unyuse; cinezela phezulu kwityhubhu uze uqhubeke nokuphakamisa ude ujikeleze umbane. Bamba le ndawo, pompa ulwelo, uze uyeke umbane ude uphume umbane, uvumele isixhobo ukuba sithathe ubunzima. Jikelezisa ngasekhohlo ukuze ukhulule i-torque, uze uqhubeke uyeke umbane ude upakishe ngamandla afunekayo.

Ukuze ugqibezele uvavanyo kwaye ukhulule ipakethi, qala ulinganise uxinzelelo kwipakethi, uze utsale intambo ngaphandle kokujikeleza ukuze ivalvu ejikelezayo ivalwe kwaye umisele ukujikeleza okujikelezayo okujikeleze ipakethi.

Yehlisa umbhobho, jikelezisa umtya, uze uwuphakamise ukuze uvule ivalvu ejikelezayo. Isixhobo singatsalwa siphume emngxunyeni.
