Mbhobho yoQhaphaza

Umbhobho wobhobhozayintsimbi drill umtya wetubula eneziphelo eziphazamisekileyo kunye nezixhobo ezidityanisiweyo, zenziwe kwaye zihlolwe kwi-API Spec 5DP ukuze ukuthengwa kungatshixa ukwamkelwa, ukulandeleka, kunye nokwenza{1}} ukuthembeka phambi kokuba umbhobho ufikelele kwi-rig.

Njengomvelisi wemibhobho yokubhola, i-Octal Pipe igxininisa kwiindawo ezilawulekayo zokungaphumeleli-kwesixhobo sokuwelda, ingqibelelo yentambo, kunye nokuthunyelwa{1}}kwizinga lerekhodi{2}}kuba uninzi lolibaziseko luqala kuqhagamshelo, hayi kumzimba wombhobho., Umbhobho we-Octal Umbhobho wokubhola uveliswa ngokuthobelana ne-API Specry umbhobho we-API7 imizimba ye-API Spec7 i-drill stem elements, kunye ne-API Spec 7-2 yokudibanisa izixhobo ezidibeneyo. Oku kuqinisekisa amandla oomatshini, ukuchaneka kobukhulu, kunye nokutshintshiselana ngezixhobo zokomba zamazwe ngamazwe.

Kwimeko yokuthenga yokwenyani, iingxaki zemibhobho yokomba aziqalisi umngxuma{0}ziqala ngawo.ayicacanga iPSL/umda webakala, imidibaniso engahambelaniyo/izixhobo ezidityanisiweyo, kunye neerekhodi zokuhlola ezingekhoyoukuba kuhlolwa okucothayo okungenayo nokudala ukulibaziseka kwe-rig{0}}ecaleni. I-Octal ibonelela nge-API 5DP yombhobho wokubhola njengeukwamkelwa{0}}iphakheji esele ilungile: igalelo elicacileyo le-RFQ (usebenzisa i-API RP 7G njengereferensi yokukhetha), i-scope yokuhlola echaziweyo, kunye nepakethi yoxwebhu elinciphisa ukusebenza kwakhona kunye nengxabano kamva.

Imibhobho yokubhobhoza ingumtya osebenzayo odibanisa inkqubo yokujikeleza komhlaba kwi-bit kunye ne-bottomhole assembly (BHA). Kwi-drilling eqhelekileyo, yenza imisebenzi emithathu ngexesha elinye. Okokuqala, ihambisa itorque ejikelezayo kunye ne-RPM ukusuka kwi-drive ephezulu okanye itafile ejikelezayo ngesixhobo -imidibaniso edityanisiweyo ukujika isuntswana. Okwesibini, ithwala umthwalo we-axial (ubunzima-kwi-{5}} bit) kwaye igobe njengoko i-trajectory yomthombo itshintsha kwaye umtya uqhagamshelana nomngxuma. Okwesithathu, lisebenza njengomzila woxinzelelo lolwelo lokomba: udaka luphonswa phantsi kombhobho wokugrumba ukuya kwimibhobho encinci, emva koko ibuyisele i-annulus ukuthutha ukusika, ukulawula uxinzelelo, ukupholisa isuntswana, kunye nokuzinzisa umngxuma.

Ngenxa yokuba indawo ephantsi komngxuma ayizinzanga{0}}imeko, umtya wokubhola usoloko uboniswa kwiimpendulo eziguquguqukayo ezibonakala kumzobo: i-axial vibration kunye nokothuka (i-bit bounce), ukungcangcazela kwecala kunye nempembelelo (ukugoba kunye nokudibanisa nodonga), kunye nokungcangcazela kwe-torsional. Ukungcangcazela kweTorsional kunokuphuhla kube sisiliphu, apho intwana icotha okomzuzwana okanye izitali ngelixa ukujikeleza komphezulu kuqhubeka, ize ikhuphe ngequbuliso-ukudala incopho yetorque kunye nokukhawulezisa ukudinwa kuqhagamshelo kunye neendawo zotshintsho. I-Bit whirl kukungazinzi kwecala apho i-bit / i-BHA ihamba phambili malunga nomngxuma ophakathi; i-whirl yangaphambili nasemva ichaza iipateni ezahlukeneyo zokujikeleza/zoqhagamshelwano kwaye inokuqhuba ukunxiba kwe-cutter ekhawulezayo kunye nomonakalo wonxibelelwano. Yiyo loo nto ukhetho lwemibhobho yokubhola kunye nokuhlolwa kuqhutywa yintembeko yoqhagamshelo, ukungaguquguquki komda, kunye nokulandeleka, hayi nje i-OD kunye nobukhulu bodonga.

Yakhelwe ngumvelisi wombhobho wokugrumba kwi-API Special 5DP ukuze ukuthengwa kungatshixa ukwamkelwa, ubushushu{1}ukuya{2}}ukulandeleka okudityanisiweyo, kwaye kwenze{3}}ukuthembeka phambi kokuba umbhobho ufikelele kwirig.
