MWD VS LWD

MWD ni iki (gupima mugihe cyo gucukura)?

MWD, isobanura gupima Mugihe cyo gucukura, ni tekinike yateye imbere yo gutema amariba yatunganijwe kugirango ikemure ibibazo bijyanye no gucukura ku mpande zikabije. Ubu buhanga bukubiyemo kwinjiza ibikoresho byo gupima mumurongo wimyitozo kugirango utange amakuru nyayo afasha mugutezimbere kuyobora imyitozo. MWD ishinzwe gupima ibintu bitandukanye bifatika nkubushyuhe, umuvuduko, hamwe na trayectory ya riba. Igena neza neza imyenge ya borehole na azimuth, igatanga aya makuru hejuru aho ishobora gukurikiranwa ako kanya nabakoresha.

LWD ni iki (Kwinjira mugihe ucukura)?

LWD, cyangwa Kwinjira Mugihe Gucukura, nuburyo bwuzuye butuma gufata amajwi, kubika, no guhererekanya amakuru mugihe cyo gucukura. Ifata amakuru yingirakamaro yo gusuzuma, harimo kugereranya umuvuduko wibyorezo nuburemere bwibyondo, bityo igaha abashoramari ubushishozi bwimbitse kumiterere yikigega. Ibi na byo, bituma habaho gufata ibyemezo bijyanye no gucukura. LWD ikubiyemo ubuhanga butandukanye nko gucukura amashanyarazi, gutema ibisasu bya kirimbuzi, gutema acoustic, no gutema magnetiki resonance. Ubu buryo bworoshya geosteering, isesengura rya geomehanike, isesengura rya petrophysical, isesengura ryamazi yibigega, hamwe no gushushanya ikigega.

Itandukaniro hagati ya MWD na LWD:

Nubwo MWD ifatwa nkigice cya LWD, hariho itandukaniro ritandukanye hagati yubuhanga bubiri.

Umuvuduko wo kohereza: MWD irangwa no gutanga amakuru yigihe-nyacyo, ituma abakora imyitozo bakurikirana ibikorwa ubudahwema kandi bagahindura byihuse nibiba ngombwa. Ibinyuranye, LWD ikubiyemo kubika amakuru mububiko bukomeye bwa leta mbere yo kohereza kubutaka kugirango isesengurwe nyuma. Ubu buryo bwo kubika no kugarura ibintu bivamo gutinda gato kuko amakuru yanditswe agomba kuboneka hanyuma akayashiraho abasesenguzi.

Urwego Rurambuye: MWD yibanda cyane cyane kumakuru yicyerekezo, yibanda kumakuru nkaya iriba na azimuth. Kurundi ruhande, LWD itanga intera nini yamakuru ajyanye no gushiraho intego. Ibi birimo ibipimo byurwego rwa gamma ray, birwanya, ubwoba, gutinda, umuvuduko wimbere nuwumwaka, hamwe nurwego rwo kunyeganyega. Ibikoresho bimwe na bimwe bya LWD bifite n'ubushobozi bwo gukusanya urugero rwamazi, bikarushaho kunoza isesengura ryibigega.

Muri rusange, MWD na LWD ni inzira zingenzi zingirakamaro mugutezimbere ibikorwa byo gucukura ku nyanja. MWD itanga amakuru nyayo-yoherejwe, cyane cyane yibanda ku makuru yerekanwe, mugihe LWD itanga umurongo mugari wo gusuzuma amakuru. Mugusobanukirwa neza hagati yubuhanga, ibigo birashobora kuzamura cyane imikorere yubucukuzi numutekano. Byongeye kandi, kubona akazu kacumbikiwe muri zone bifite uruhare runini mugukora neza. Urebye ibi bintu birashobora koroshya ibikorwa byo gucukura no kugira uruhare mubikorwa rusange.
