Amathuluzi Kawoyela We-Landrill Aveza Umhlahlandlela Wokukhetha Wesayensi Weziplagi Zebhuloho Ezingancibiliki

Emkhakheni oyinkimbinkimbi wemisebenzi yensimu kawoyela, ukukhetha okulungileipulaki yebhuloho elincibilikayokubalulekile ekwakheni nasekukhiqizeni imithombo ngempumelelo. I-Landrill Oil Tools yethule umhlahlandlela wokukhetha ophelele osekelwe ezinqumweni - ezisekelwe emthini, okwenza inqubo ibe lula kochwepheshe bemboni.

Isinyathelo 1: Ukushisa - Ukufaniswa Kwezinto Eziqhutshwayo

Izinga lokushisa lokwakheka liyisici sokuqala esibalulekile. Linquma ukuzinza kokushisa kanye nezinga lokuncibilika kwezinto zokuxhuma amabhuloho. Ezindaweni eziphansi (ngaphansi kuka-60℃), amamodeli e-Single Slip noma e-Compacted Double Slip afana ne-LZ001, LZ002, kanye ne-LZ022 afaneleka kakhulu. Lawa anikeza ubukhulu obuncane (ubude ≤ 330mm) kanye nokuncibilika okusheshayo (20 - 40mg · cm⁻² · h). Ezimweni eziphakathi (60 - 90℃), ama-Compacted Double Slip noma ama-Double Slip plug afana ne-LZ008, LZ016, kanye ne-LZ027 ukukhanya, okunikeza ukuzinza okuthuthukisiwe kokubambelela kwezimo ezimaphakathi (≤ 70MPa). Imithombo yokushisa ephezulu (ngaphezu kuka-90℃) idinga izixazululo ze-Double Slip noma ze-Full Metal ezifana ne-LZ025, LZ030, kanye ne-LZ031, ezimelana nokucindezela okuphezulu (85MPa) kanye nakho konke - ukumelana nokugqwala kwensimbi.

Isinyathelo 2: Ukuguquguquka kosawoti kanye nokugqwala

Usawoti (ukuhlushwa kwe-Cl⁻) kanye nezindawo ezigqwalisayo kunciphisa kakhulu ukukhetha. Imithombo yosawoti ophansi (ngaphansi kuka-500mg/L) ifanelekela uchungechunge lwe-LZ001/LZ002, ngesilinganiso sokuncibilika esingu-20 – 40mg·cm⁻²·h. Ezilungiselelweni zosawoti ophezulu (ngaphezu kuka-15000mg/L), uchungechunge lwe-LZ025/LZ028 luhamba phambili, lunesilinganiso sokuncibilika esingu-80 – 120mg·cm⁻²·h. Ezindaweni ezine-acidic (pH ≤ 3), uchungechunge lwe-Full Metal LZ030 luyanconywa, ngenxa yokugqoka kwalo okumelana ne-acid kanye nesilinganiso sokuncibilika esingu-20 – 300mg·cm⁻²·h emazingeni okushisa aphezulu.

Isinyathelo 3: Ukucatshangelwa Kwesicabha Nokucindezela

Usayizi wekhesi kanye nomfutho wokwakha nakho kubalulekile. Amakhesi amancane (≤ 4″) ahambisana kahle ne-Single Slip LZ001 (OD 89mm). Ukusebenza komfutho ophezulu (ngaphezu kuka-70MPa) kuzuza kwi-Double Slip LZ025 (Pressure 85MPa), enomklamo wokushelela oqondene nezinhlangothi ezimbili ukuze kube namandla okusika aphezulu angu-30%. Kumakhesi aguqukile, i-Compacted Double Slip LZ022 (OD 110mm) iqinisekisa ukudluliseka kumakhesi angu-4.5″.

Ngokulandela lesi sihlahla sezinqumo, amaqembu e-oilfield angakhetha ngokunembile ama-bridge plugs ancibilikayo, athuthukise ukusebenza kahle kwemithombo futhi aqinisekise ukusebenza okungenamthungo ezimweni ezahlukahlukene ze-geological. Umhlahlandlela we-Landrill Oil Tools unika imboni amandla okubhekana nezinselele zemithombo eziyinkimbinkimbi ngokunemba kwesayensi.
