1. Ukutholwa Kwedatha Yesikhathi Sangempela
I-LWD: Inikeza ukutholwa kwesikhathi sangempela kwedatha yokuhlola ukwakheka, okuhlanganisa ukumelana nokumelana, imisebe ye-gamma, ne-porosity. Lokhu kuvumela ososayensi bendawo nonjiniyela ukuthi bahlole izakhiwo zamachibi njengoba kuqhubeka ukumba.
I-MWD: Ihlinzeka ngokuqapha okusheshayo kwamapharamitha okubhola njenge-trajectory, isisindo kubhithi, netorque. Le datha ibalulekile ekuthuthukiseni imisebenzi yokumba kanye nokuqinisekisa ukuzinza kwe-wellbore.
2. Ukuqonda Okuthuthukisiwe Kwechibi
I-LWD: Isiza ukucaciswa kwezindawo zokugcina amanzi ngokuqhubekayo ngokulinganisa izakhiwo zokwakheka. Lokhu kuvumela ukuqonda kangcono i-lithology, okuqukethwe koketshezi, nezici zembobo.
I-MWD: Inikela ekuqondeni kwe-reservoir ngokunikeza imininingwane kungcindezi yokwakheka, izakhiwo eziwuketshezi, namapharamitha we-geomechanical. Lolu lwazi lusiza ekuhleleni kahle nasezinqumweni zokuphathwa kwamachibi
3. I-Geosteering ne-Wellbore Placement
I-LWD: Inika amandla i-geosteering enembile ngokunikeza idatha yesikhathi sangempela kumingcele yokwakheka nezindawo ezithwala i-hydrocarbon. Lokhu kuqinisekisa ukubekwa okunembile kwe-wellbore ukuze uthole ukuthintana nedamu elilungile.
I-MWD: Isiza ekwenzeni i-geosteering ngokuqapha imingcele yokumba kanye nokunikeza impendulo mayelana ne-trajectory yomthombo. Ama-opharetha angalungisa isiqondiso sokumba ngesikhathi sangempela ukuze bazulazule ezindaweni eziyinkimbinkimbi futhi bagweme izingozi.
4. Ukusebenza Ngempumelelo Kokumba kanye Nokonga Izindleko
I-LWD: Ithuthukisa ukusebenza kahle kokumba ngokuhlonza izindawo zokumba ezivumayo kanye nokwenza kahle ukubekwa kwemithombo. Lokhu kunciphisa isikhathi sokumba, kunciphisa izindleko zokusebenza, futhi kukhulisa amandla omnotho wemithombo.
I-MWD: Ithuthukisa ukusebenza kahle kokumba ngokuthuthukisa amapharamitha wokumba kanye nokunciphisa isikhathi esingakhiqizi. Ukuqapha ngesikhathi sangempela kuvumela ukulungiswa ngokushesha emisebenzini yokumba, okuholela ekongeni kwezindleko kanye nokwanda kokukhiqiza kokumba.
5. Ukunciphisa Ubungozi Nokuphepha
I-LWD: Isiza ukunciphisa izingozi zokumba ngokunikeza ukutholwa kusenesikhathi kwezinguquko zokubunjwa, ukungena koketshezi oluningi, kanye nezingozi zokumba. Lokhu kuvumela opharetha ukuthi basebenzise izinyathelo zokuvimbela futhi bagcine ubuqotho be-wellbore.
I-MWD: Inikela ekuphepheni ngokuqapha izimo zokumba kanye nokuxwayisa opharetha ngezingozi ezingaba khona ngesikhathi sangempela. Le ndlela yokwenza izinto ngokushesha inciphisa amathuba ezingozi futhi iqinisekise ukuphepha kwabasebenzi kanye nezisetshenziswa.
6. Ukwandisa Ukubuyiselwa Kwe-Hydrocarbon
I-LWD: Idlala indima ebalulekile ekwandiseni ukutholwa kwe-hydrocarbon ngokuhlonza izikhawu zamachibi akhiqizayo kanye nokuthuthukisa amasu okuqeda. Lokhu kuholela ekusebenzeni kahle okuthuthukisiwe kanye nokwanda kwesivuno sokukhiqiza.
I-MWD: Isiza izinqumo zokubekwa kahle kwemithombo kanye nokuphathwa kwedamu, ekugcineni ikhulise ukutholakala kwe-hydrocarbon futhi yandise impilo yezomnotho yezizinda zikawoyela negesi.
Ngezansi kuneshadi elichaza umehluko oyinhloko phakathi Kokuloga Ngenkathi Umba kanye Nokulinganisa Ngenkathi Umba.
| Isici | Ukugawula Ngenkathi Umba (LWD) | Ukulinganisa Ngenkathi Umba (MWD) |
| Inhloso | Ukutholwa kwesikhathi sangempela kwedatha yokuhlola ukwakheka | Ukuqapha kwesikhathi sangempela nokulawula imisebenzi yokumba |
| Ukutholwa Kwedatha | Ikala izakhiwo zokwakha ezifana ne-resistivity, imisebe ye-gamma | Ikala amapharamitha okubhoboza njenge-trajectory, isisindo kubhithi |
| Indawo Yamathuluzi | Kuhlanganiswe eduze nendawo yokubhoboza ngaphakathi kwe-Bottom Hole Assembly (BHA) | Iphinde ihlanganiswe eduze kwebhithi yokubhola ngaphakathi kwe-BHA |
| Uhlobo Lwedatha Eqoqiwe | Izakhiwo zokwakheka kufaka phakathi ukumelana, ukuminyana, i-porosity | Amapharamitha ahlobene nokubhoboza njenge-trajectory, isisindo kubhithi |
| Izinhlelo zokusebenza | Ukuhlolwa kokwakheka, i-geosteering, ukuhlukaniswa kwezinhlamvu ze-reservoir | Ukulungiswa kokubhoboza, ukubekwa kwe-wellbore, i-geosteering |
| Izinzuzo | Ukuhlolwa kokwakheka kwesikhathi sangempela, ukuqonda okuthuthukisiwe kwechibi | Ukuqapha ngesikhathi sangempela, ukuthuthukiswa kokusebenza kahle kokumba |
I-Gyroscope inclinometer evela ku-Vigor manje isibe yinye yezinketho eziyinhloko zokugawulwa kwemithi Ngenkathi Umba ngenxa yokunemba kwayo okuphezulu, ukusebenziseka kalula nokuqina, futhi iye yasetshenziswa emikhakheni emikhulu kawoyela emhlabeni wonke futhi iye yaqashelwa futhi yaqinisekiswa ngabasebenzisi bokugcina. Uma unentshisekelo ku-Vigor's gyroscope inclinometer noma insizakalo yasensimini, sicela ungangabazi ukusithinta ukuze uthole ukwesekwa kobuchwepheshe obuchwepheshile.
