MWD VS LWD

Kodi MWD (Measurement When Drilling) ndi chiyani?

MWD, kutanthauza Measurement When Drilling, ndi njira yaukadaulo yodula mitengo yomwe yapangidwa kuti ithetse mavuto obwera chifukwa cha kubowola mopitilira muyeso. Njira imeneyi imaphatikizapo kuphatikiza zida zoyezera mu chingwe chobowola kuti mupereke chidziwitso cha nthawi yeniyeni chomwe chimathandizira kuwongolera chiwongolero cha kubowola. MWD ili ndi udindo woyeza zinthu zosiyanasiyana zakuthupi monga kutentha, kuthamanga, ndi njira ya chitsime. Imatsimikizira ndendende momwe borehole imayendera ndi azimuth, ndikutumiza detayi pamwamba pomwe imatha kuyang'aniridwa nthawi yomweyo ndi ogwira ntchito.

Kodi LWD (Kudula Mitengo Pamene Mukubowola) ndi chiyani?

LWD, kapena Logging When Drilling, ndi njira yokwanira yojambulira, kusunga, ndi kutumiza zidziwitso panthawi yoboola. Imajambula deta yowunikira mapangidwe, kuphatikizapo kuyerekezera kwa pore ndi kulemera kwamatope, motero kumapatsa ogwira ntchito chidziwitso chozama cha chikhalidwe cha nkhokwe. Izi, zimalola munthu kupanga zisankho mwanzeru pankhani yoboola. LWD imaphatikizapo njira zosiyanasiyana monga kubowola ma electromagnetic, kudula mitengo ya nyukiliya, kudula mitengo mwamawu, ndi kudula mitengo ya nyukiliya. Njirazi zimathandizira kuwunika kwa geosteering, kusanthula kwa geomechanical, kusanthula kwa petrophysical, kusanthula kwamadzi am'madzi, ndi mapu osungira madzi.

Kusiyana Pakati pa MWD ndi LWD:

Ngakhale MWD imatengedwa kuti ndi gawo laling'ono la LWD, pali kusiyana kosiyana pakati pa njira ziwirizi.

Kuthamanga kwa Kutumiza: MWD imadziwika ndi kupereka kwa data zenizeni zenizeni, zomwe zimathandiza oyendetsa kubowola kuyang'anira ntchito mosalekeza ndikusintha nthawi yomweyo ngati kuli kofunikira. Mosiyana ndi zimenezi, LWD imaphatikizapo kusunga deta mu kukumbukira kokhazikika musanatumize pamwamba kuti muwunikenso. Kusungirako ndi kutulutsa kumeneku kumapangitsa kuti pakhale kuchedwa pang'ono chifukwa deta yojambulidwa iyenera kutengedwa ndikusinthidwa ndi akatswiri.

Mulingo wa Tsatanetsatane: MWD imayang'ana kwambiri zamayendedwe, kuyang'ana zambiri monga kutengera kwa chitsime ndi azimuth. Kumbali inayi, LWD imapereka zambiri zambiri zokhudzana ndi mapangidwe omwe mukufuna. Izi zikuphatikizapo miyeso ya gamma ray, resistivity, porosity, kuchedwa, kupanikizika kwa mkati ndi annular, ndi milingo ya vibration. Zida zina za LWD zimatha kusonkhanitsa zitsanzo zamadzimadzi, zomwe zimawonjezera kulondola kwa kusanthula kwamadzi.

M'malo mwake, MWD ndi LWD ndi njira zofunika kwambiri pakuwongolera ntchito zoboola m'mphepete mwa nyanja. MWD imapereka kufalitsa kwa data mu nthawi yeniyeni, makamaka kumayang'ana kwambiri malangizo, pomwe LWD imapereka kuchuluka kwa data yowunikira. Pomvetsetsa kusiyana pakati pa njirazi, makampani amatha kupititsa patsogolo ntchito yawo yoboola bwino komanso chitetezo. Kuphatikiza apo, kusungitsa ma cabins okhala ndi malo ocheperako kumathandizira kwambiri kuwonetsetsa kuti ntchito yoboola bwino. Kuganizira zinthu zimenezi kungathandize kuti ntchito yobowola ikhale yabwino komanso kuti zinthu ziziyenda bwino.
