Ibipimo bisanzwe Mugihe cyo gucukura (MWD) ibikoresho

Igipimo gisanzwe Mugihe Sisitemu yo gucukura (MWD) igizwe nubushakashatsi bwo hasi, sisitemu yo kohereza amakuru hamwe nibikoresho byo hejuru. Ibyerekezo byerekanwa bipimwa na probe yamanutse kandi byoherejwe na mud pulse telemetrie cyangwa amashanyarazi ya electronique. Hamwe nibikoresho byinshi uburyo butandukanye bwo gukora burashobora guhindurwa na pulse ikurikirana.

Hasi

Iperereza ryibipimo byo gupima Mugihe sisitemu yo gucukura (MWD) isanzwe igizwe na moteri eshatu zikomeye za leta kugirango zipime impengamiro hamwe na magnetometero eshatu zikomeye za leta zo gupima azimuth. Ipasi ya downhole isa niy'ibikoresho bikomeye bya leta imwe hamwe n’ibikoresho byinshi birasa kandi bigashyirwa muri cola itari magnetique.

Kohereza amakuru

Uburyo butatu bwibanze bwo kohereza amakuru hejuru burahari:

1.Icyuma cyitwa pulse telemetry gikubiyemo amakuru muburyo bwa binary ikohereza kubutaka hejuru yimpanuka nziza cyangwa mbi yumuvuduko ukomoka mumazi yo gucukura aho bigaragazwa na transducers yumuvuduko kuri pipe-stand hanyuma ikabikwa na mudasobwa yo hejuru.

2.Ibihe bya telemetrie ikomeza, uburyo bwa pulse nziza, ikoresha igikoresho kizunguruka gitanga ibimenyetso byerekana umurongo uhoraho wohereza amakuru ya kodegisi ikomatanyirijwe mu byiciro bigenda bihindagurika ku muvuduko w’umuvuduko ukagera ku nkingi y’ibyondo. Inyungu nyamukuru ya sisitemu ikomeza ya telemetrie hejuru ya sisitemu nziza kandi itari nziza ni inshuro ndende ya pulse igabanya igihe gikenewe cyo gukora ubushakashatsi.

3.Ikwirakwizwa rya elegitoroniki ikoresha imiyoboro mike ya electromagnetic yumurongo inyura mumikorere. Ibi byakirwa hamwe na antenne yashyizwe mubutaka bwegeranye na site ya rig. Sisitemu ifite intera ndende iterwa no kurwanya imiterere. Hasi yo kurwanya, imbaraga ni intera yingirakamaro. Kugeza ubu ibi mubisanzwe biri hagati ya metero 1000 na 2000. Bitandukanye na sisitemu nziza, mbi kandi ikomeza ya telemetrie ya sisitemu, sisitemu ya electromagnetic telemetry sisitemu irashobora gukoreshwa mugihe iriba rifunze, urugero kubucukuzi buke.

Ibikoresho byo hejuru

Ubusanzwe ubuso bwibice byibyondo Gupima Mugihe Sisitemu yo gucukura (MWD) ikubiyemo transducers yumuvuduko wo kumenya ibimenyetso, ibikoresho bya elegitoronike yerekana ibikoresho, hamwe na analogue hamwe nibisomwa bya digitale hamwe nabapanga.

Ubwishingizi bufite ireme

Ubwishingizi bufite ireme bwo gupima Mugihe ibikoresho byo gucukura (MWD) bisa nkibikoresho bya leta bikomeye hamwe nibikoresho byinshi. Usibye ibi, ikizamini cyimikorere kigomba gukorwa mbere yo gukora BHA kugeza hasi.

Uburyo busanzwe:

1.Kora ikizamini cyimikorere yo hejuru. Reba guhuza Ibipimo Mugihe Gucukura (MWD) igikoresho hamwe na sub yunamye, niba bishoboka.

2.Kora uburyo bwo gupima ikizamini.

3.Igipimo Mugihe Igikoresho cyo Gucukura (MWD) kigomba kugeragezwa, igihe cyose ari ingirakamaro kubikora, hafi yubuso bushoboka. Mubisanzwe ni 1 kugeza kuri 2 ya drillpipe munsi ya rotary. Uburyo bukurikira:

-kugerekaho kelly cyangwa hejuru yo hejuru;

-kora ubushakashatsi hanyuma utegereze kohereza byuzuye. Ibipimo byubushakashatsi bushimishije ni:

-ubushake bugomba kuba munsi ya 1 °;

-ikibanza gikurura imbaraga kigomba kuba muri 0.003 g yagaciro kateganijwe;

-wandike ko amakuru ya magnetiki yafashwe imbere muri riser cyangwa case bitemewe;

-niba ikizamini gishimishije, kandi ibyondo byondo byacuzwe bikomeza gukora. Niba bidashimishije, subiza igikoresho hejuru.

4.Kora ubushakashatsi bwibipimo. Iruka mu mwobo kugirango igipimo cyo gupima Mugihe icyuma (MWD) sensor iri kuri sitasiyo ngenderwaho hanyuma ukore ubushakashatsi bwibipimo bikurikira:

5.Ibipimo ngenderwaho biri kuri metero 15 munsi yinkweto zabanjirije iyi, ariko birahagije kure yandi mariba kugirango wirinde kwivanga kwa magneti kubipimo mugihe cyo gucukura (MWD).

6.Kora ubushakashatsi. Ibi bizafatwa hepfo gato mbere yo gucukura kandi nibyiza nko hafi yipimwa ryanyuma Mugihe ubushakashatsi bwo gucukura (MWD) bwakorewe kubanza bishoboka. Birashobora kuba nkenerwa gukoresha igipimo cyanyuma ariko Igipimo Mugihe Mugihe cyo Gucukura (MWD) ubushakashatsi bwakozwe mbere. Ubu bushakashatsi buzemeza neza amakuru yubushakashatsi bwakozwe mbere. Iyo itandukaniro riri hejuru ya dogere zirenga ebyiri muri azimuth na kimwe cya kabiri cya dogere yubushake byagaragaye muri ubu bushakashatsi bwakozwe, ibiro bigomba kubazwa kugira ngo bitange inama kubikorwa bikenewe.

7.Kora mu mwobo hanyuma ukore imyitozo mbere yo gukora ubushakashatsi nkuko bisabwa cyangwa icyerekezo cyibikoresho.

8.Ubushakashatsi buteye gushidikanya bugomba kugenzurwa no gufata ikindi Gipimo Mugihe Ubushakashatsi (MWD).

Nkumushinga wumwuga wibikoresho byo gutema ibiti, abajenjeri bacu ba tekinike bafite uburambe bwimyaka myinshi yo kurangiza no gutema ibiti, ibikoresho byose byo gutema ibicuruzwa bishobora kugurishwa ukurikije ibisabwa nabakiriya, birumvikana ko dushobora no kuguha serivise kumurongo kugirango tugufashe ukorera ibipimo kurubuga. Niba ushishikajwe no kurangiza no gutema ibiti, nyamuneka ntutindiganye kuvugana nitsinda rya Vigor, tuzaguha inkunga yubuhanga bwa tekiniki hamwe ninkunga yibicuruzwa mugihe cyambere.
