Umahluko phakathi kwe-Cement Retainers kunye neBridge Plugs

Ukugrumba & Ukugaya Eyona Nkqubo:

Ukuba imeko ukwenza ukomba okanyeimisebenzi yokusila(ijunk mill), inkqubo ecetyiswayo yile ilandelayo:

• Sebenzisa aIncinci ye-tricone(IADC Bit Codes2-1, 2-2, 2-3, 2-4, kunye ne-3-1) - ukubunjwa kanzima okuphakathi.PDC Bitayikhethwa.
• Eyona RPM ingcono iya kuba yi-70 ukuya kwi-125
• Sebenzisa i-viscosity yodaka ye-60 CPS yokususwa kwe-cuttings
• Ubunzima kwibit - Faka i-5-7 Klbs. De isiphelo phezulu mandrel ibhodlozwa kude, nto leyo 4-5 intshi. Emva koko wandise i-3 Klbs. yobunzima nge-intshi nganye yobukhulu be-bit ukugrumba inxalenye eseleyo. Umzekelo: I-4-1/2 bit iya kusebenzisa i-9,000-13,500 lbs. ubunzima.
• Musa ukusebenzisa ubunzima ngaphezu kwesixa esicetyiswayo. Ubunzima obungekho ngqiqweni bunokukrazula amaqhekeza ePlug yeBridge, kwaye ukwenza olunye uhambo kuya kuba yimfuneko ukususa amaqhekeza ukuze kuvumeleke ukungena ngakumbi.
• Drill iiKhola– iya kusetyenziselwaubonelele ngeWOB efunekayokwayeIntwana yokugrumbaUmzekelo: 4-1/2 thru 5-1/2 (8 imiz.) 7 nangaphezulu (12 min.).
• Iibhaskithi eziyinkunkuma– Ibhaskithi enye okanye ngaphezulu iya kusetyenziswa kwindawoumtya wokubhola. Ukuba ukujikeleziswa okubuyela umva kucwangcisiwe, naziphi na izixhobo ezikwityhubhu okanye umtya wokubhobhoza kufuneka zibe ne-ID efanayo yebit ukuze ukusika kungabi bhulorho.
• Isantya soNyaka– 120 ft/min iya kuqwalaselwa.
• Ingobozi yenkunkuma ngaphezulu kwentwana.

Izixhobo ezifunekayo kuSeto kunye neNkonzo

• I-Wireline Adapter Kit
• INdibano Yetywina Elihlabayo
• I-Tubing Centralizer
• Isixhobo sokuSeta oomatshini
• I-Wireline Adapter Kit ye-Flapper Bottom
• Isixhobo sokuSeta i-Hydraulic

Ukuseta iPlug yeBridge kunye nokuKhululwa kweeMechanism

Ngenene, ukusetwa kunye neendlela zokufumana kwakhona ziyakwahluka kumenzi-mveliso. Kodwa, sazisa inkqubo ngokubanzi ukuze ufumane umbono.

Iseti yoxinzelelo

Baleka ubunzulu obufunekayo ngelixa uqhagamshelwe kwisixhobo sayo sokubuyisa.

Thatha, jikelisa iXX (1/4) jikela ngasekunene kwiplagi, kwaye uhlise iityhubhu ukuseta iziliphu ezisezantsi.

Tsala uxinezeleko olwaneleyo lokupakisha izinto, yehlisa, emva koko ucofe kwakhona ukuze uqinisekise ukusetwa kweplagi (15,000 ukuya kwi-20,000 lbs).

Emva kokuseta iplagi, yehlisa ubunzima betyhubhu, ubambe itorque ngasekhohlo, kwaye uthathe ukukhulula isixhobo esibalekayo kwiplagi.

Thatha, jikelisa iXX (1/4) jikela ngasekunene kwiplagi, kwaye uhlise iityhubhu ukuseta iziliphu ezisezantsi.

Yehlisa ubunzima obaneleyo ukupakisha izinto, emva koko uphakamise ukuseta iziliphu eziphezulu kwaye uthobe kwakhona (15,000-20,000 lbs).

Emva kokuseta iplagi, yehlisa ubunzima betyhubhu, ubambe itorque ngasekhohlo, kwaye uthathe ukukhulula isixhobo esibalekayo kwiplagi.

Ukukhulula Inkqubo

Iityhubhu esezantsi ide ibe ithegi yesixhobo sokubuyisela kwiplagi yebhulorho kunye neentambo ezifanayo.

Jikelezisa ukuhlamba isanti kwiziliphu zeplagi.

Vula ivalve ngokuthoba ubunzima, ubambe itorque ngasekunene, emva koko uphakamise.

Lindela ukulingana koxinzelelo.

Tsalela phezulu ukuze ukhulule iziliphu, phumla izinto zokupakisha, kwaye uphinde ubambe.

Iplagi ngoku ingakhululeka ukuba ihambe.

Ukuba iplagi ayizi kukhulula ngokwesiqhelo, yehlisa, usete kwakhona, emva koko tsala phezulu ukucheba ii-J-pins kwaye ukhulule iplagi (i-J-pins iya kucheba nge-40,000 ukuya kwi-60,000 lbs nganye).

Nje ukuba uphumelele ukucheba izikhonkwane, isixhobo asiyi kukwazi ukushukuma emngxunyeni.

Iimpawu ezibalulekileyo zePlug yeBridge onokucinga ngayo

Iiplagi ezininzi zebhulorho ziza nokudlula okukhulu kwangaphakathi ukuze kuncitshiswe impembelelo yokuswabha ye-RIH & POOH. Le bypass ivula ngaphambi kokukhulula iplagi ukwenza ukulingana koxinzelelo. Ezinye iiBPs nazo ziyakwazi ukuseta kwaye zipakishe into ekuxinaniseni.

Ukuqhutywa kwesixhobo nako kufuneka kuqwalaselwe ukonga ixesha kunye neendleko zokusebenza.

Ezinye izixhobo ziza kunye nefitsha yokuguqulela kwisigcini sesamente okanye ukusuka kwiseti yomatshini ukuya kwiseti yocingo.

Ucociso olulungileyo phakathi kweplagi yebhulorho kunye necasing kufuneka ithathelwe ingqalelo nokuba inemisebenzi ebalekayo ekhawulezayo nekhuselekileyo ngaphandle kokuseta ngequbuliso.

Kukho ezinye ziyilo ezithintela ukunyakaza ngenxa yeziliphu ezichasiweyo. Olu phawu luqinisekisa ukuba akuyi kubakho ntshukumo kwimeko yokunyuka koxinzelelo oluhlukeneyo kunye nolwalathiso (phezulu okanye phantsi).

Iiplagi zebhulorho ziyimfuneko ephantsi kwezixhobo ezisetyenziselwa ukusebenza kwe-oyile kunye negesi yokulinganisa uxinzelelo, ukulahlwa okwethutyana, kunye nokuhlukaniswa kwendawo. Kukho iintlobo ezininzi zeeplagi zebhulorho ezikhoyo ukuze zilungele usetyenziso olwahlukeneyo. Uhlobo ngalunye luneempawu zalo ezizodwa kunye neenzuzo ezenza ukuba zilungele iintlobo ezithile zokusebenza. Ukusebenzisa uhlobo olufanelekileyo lweplagi yebhulorho kunokunciphisa kakhulu ixesha lokulawula kunye nokuqinisekisa iimvavanyo zoxinzelelo oluyimpumelelo.

Ukuba unomdla kwiimveliso zeplagi yebhulorho yeVigor, nceda ungalibazisi ukunxibelelana nathi ukuze ufumane ezona mveliso zibalaseleyo kunye nenkonzo esemgangathweni.
