Zvishandiso Zvekudhonza Zvinotungamira Zvakajairika

Nyaya nhatu dzinofanira kugadziriswa mukudzora nzira dzekufamba kwemvura:

① Gadzirai gomba repasi (BHA) zvine musoro kuti mudzore mwero wekuchinja kwekona yekutsauka kwegomba.

② Gadzira kana kusarudza maturusi emugomba une zvivakwa zvakakosha kudzora mwero wekuchinja kwekona yegomba.

③ Sarudza nekudzora huremu hwebhiti (WOB) zvine musoro kuti udzore mwero wekupinda kwebhiti wakamira uye hukuru hwemasimba ekuumbwa, nokudaro uchikwanisa kudzora kutenderera kwebhiti.

Zvishandiso zvechinyakare zvekuboorera zvinoshandisa nzira dzinosanganisira ma subs ekuboorera, ma non-magnetic drill collars (NMDC), ma heavy-weight drill pipes (HWDP), ma stabilizers, ma key-seat wipers, nezvimwewo.

I. Chikamu Chinotungamira

1. Mhando

Chikamu chakatwasuka chinonongedzera divi: Chinoshandiswa pakuboorera divi uchishandisa mabhora ekugadzira madziro ekugadzira madziro (PCD).

Directional bent sub: Inoshandiswa pakuboorera zvakananga nekushandisa ma straight-housing progressive cavity drills (PCD).

2. Chimiro Chekutanga

1) Sub Yakatwasuka Inotungamira

Zvikamu: Housing 4, centralizing sleeve 1, direction key 3, set screw 2

2) Kutungamira Kunopinza Sub

Zvikamu: Housing 4, centralizing sleeve 1, directional key 3, set screw 2. Kana ichienzaniswa ne directional straight sub, ine structural bend angle λ, uye formula yekuverenga ndeiyi:λ = 57.3 × (a – b) / d

II. Kola Yekudhirowa Isina Magnetic (NMDC)

1. Basa

Zvishandiso zvekuyera magnetic kudzivirira zvikanganiso zvekuyera.

Ita mabasa emakarasi ekuboorera akajairika.

2. Zvinhu zveMakori eKuboorera Asiri eMagineti

Zvikuru zvinosanganisira Monel alloy (ine mhangura, nickel, chromium, nezvimwewo), chromium-nickel alloy, austenitic alloy yakavakirwa pa chromium-manganese, beryllium-copper alloy, SMFI non-magnetic steel, uye manganese-chromium-nickel steel yemumba.

3. Kusarudzwa kweUrefu hweKora reKudhonza Risiri reMagineti

Tarisa ku "Mepu yeHorizontal Earth Magnetic Field Intensity". Kusarudzwa kwakaringana kwehurefu hwekori rekudhira risiri remagineti kunoita kuti kuyerwa kwakarurama kweazimuth yemagineti muchikamu chegomba rakavhurika. Kana simba remagineti renzvimbo yacho rakakwirira, kori rekudhira risiri remagineti rinoreba.

4. Kuongorora nekushandisa maCollar eKuboorera Asiri eMagineti

1) Kutwasuka kwekunze kwe cylindrical kwe collar yekuboorera isina magineti kunofanira kuva ≤ 2mm/m, uye kutwasuka kwehurefu hwese kunofanira kuva ≤ 5mm/m.

2)Kukwenya pamusoro pepombi yekori yekuboorera isina magineti hakufanirwe kudarika muganho wekukwenya wakatarwa.

3)Pamusoro peshinda panofanira kunge pakanyatsotsetseka, pasina mavanga asina kuenzana, mitswe, kupenga, kana zvimwe zvinokuvadza.

4）Torque yekugadzira yeshinda dzechibhora dzisiri dzemagineti inofanira kuva ≥ torque shoma yakatarwa yekutenderera.

5)Kupinda kwesimba remagineti uye kufanana kwesimba remagineti kwekorari yekudhirowa isiri yemagineti zvinofanira kuongororwa kamwe chete pagore, uye mhedzisiro yekuongorora inofanira kuenderana nezvinodiwa neNon-Magnetic Drill Collar Standard (SY5145-86).

III. Pombi Yekubhoorera Inorema (HWDP)

Inoshandiswa pasi peBHA kutsiva mabhora ekuboorera pakuisa simba. Mukushanda kwekutungamira nemidziyo yekufambisa, inoderedza nzvimbo yekubata nemadziro etsime, inoderedza kuramba kwekukweshana, inobatsira kutsvedza, inowedzera kuchengetedzeka kwemugomba, uye inobatsira kudzora maparamita etsime rekutungamira. Inoshandawo sechikamu chekuchinja pakati pemabhora ekuboorera nemapombi ekuboorera kuderedza kuchinja kwekuoma.

IV. Chinosimbisa

1.Mashandisirwo eStabilizers muDirectional Drilling

MumaBHA akabatana uye maBHA anodonhedzwa, zvinosimbisa zvinoshanda sezvikamu zvekusimbisa. Nekugadzirisa nzvimbo yezvinotsigira muBHA yepasi, mamiriro ekumanikidzwa kweBHA yepasi anogona kuchinjwa kuti pave nekudzora nzira yekufamba zvakanaka.

2.Wedzera kuomarara kweBHA yepasi kuti usimbise kutsauka kwegomba uye azimuth. MumaBHA ekubata-angle, kuomarara kweBHA yepasi kunowedzerwa nekuderedza daro riri pakati pe bit ne stabilizer, uye pakati pe stabilizers, kuitira kuti pasave nekudzvanywa kwe BHA yepasi uye kuwana simba rekubata kutsauka.

3.Pfeka tsime remvura kuti tsime remvura rive rakapfava uye rakatsetseka, izvo zvinobatsira kuderedza matambudziko ari mugomba.

Cherechedza! Paunenge uchiisa chinodzivirira mugomba wochiburitsa mugomba, nyatsoyera dhayamita yekunze yechinodzivirira, tarisa mamiriro acho ekupfekwa uye nzvimbo yachinoiswa muBHA. Kupfekwa kwedhayamita yekunze kwechinodzivirira hakufanirwe kudarika 2mm.

Mhando dzezvigadziriso:

Chinosimbisa mativi maviri chembabvu chakatwasuka. Chinosimbisa mativi maviri chembabvu shanu (matatu)

Chinosimbisa denderedzwa remaonde mashanu (maonde matatu)r Chivharo che stabilizer chinotsiviwa

Chinosimbisa madziro chine mativi matatuChinotsiviwa chinotsiviwa

V. Chipunu cheKiyi-Chigaro

Chimiro chemuchina wekugadzirisa chigaro chekiyi chakafanana nechemuchina wekugadzirisa mativi ose. Chimiro chayo chose chidiki pane chemuchina wekugadzirisa mativi ose asi chakakura kupfuura chemuchina wekugadzirisa mativi ose. Kusiyana nemudziyo wekugadzirisa mativi ose, mapendekete ekumusoro neapasi emuchina wekugadzirisa chigaro chekiyi akabatanidzwa nemagetsi akaomarara kuita chimiro chekona, icho chine mabasa ekucheka, kusanganisa, uye kupukuta zvigaro zvekiyi.

Nzvimbo yemuchina wekupukuta chigaro chekiyi mutambo yekuboorera ndeiyi inotevera:

1. BHA Yakagadzirirwa Kupukuta Zvigaro Zvine Makiyi

Magadzirirwo eBHA ekupukuta zvigaro zvemakiyi: Bit + drill collar diki (50)～60m) + chipunu chekiyi + chirongo chekuboorera + pombi yekuboorera inorema (HWDP).

Pakupukuta zvigaro zvekiyi zvakareba, BHA inotevera inogona kushandiswa: Bit + stand imwe ye drill collar diki + key-seat wiper + stand imwe ye drill collar diki + flexible joint + drilling jar + heavy-weight drill pipe (HWDP).

Dhayamita yekunze yekora yekuboorera diki mutambo yekuboorera inofanira kunge yakafanana nedhayamita yekunze yejoini yepombi yekuboorera inoshandiswa panguva yekuboorera. Paunenge uchimhanyisa tambo yekuboorera kusvika pa100m pamusoro pechigaro chekiyi, dzora kumhanya kwekumhanya; kana paine kudziviswa, tanga kudzoreredza uye dzora zvakanyanya WOB (kazhinji isingasviki 49kN).

2. Kupukuta Zvigaro zveKiyi Paunenge Uchiboorera

Mukuchera nedivi, kutanga kubva pachikamu chakaunganidzwa, machira ekuisa zvigaro zvekiyi anowanzo shandiswa muBHA. Zvichienderana nekukombama kwenzvimbo yakaboorwa yemvura uye kuumbwa kwayo, chirairo chekuisa zvigaro zvekiyi chinoshandiswa kudzokorora kudzokororwa muzvikamu zve "gumbo rembwa" uko zvigaro zvekiyi zvingangoumbwa, kuitira kudzivirira kuumbwa kwechigaro chekiyi.

VI. Vharuvhu Inoyangarara

Mabasa ayo makuru ndeekudzivirira kudzokera shure kwemvura yekuboorera (iyo inogona kukanganisa maturusi ekuyera gomba) uye kudzivirira maburi e bit kuti asavharwe.

VII. Chikamu cheHanger

Chishandiso chekuyera panguva yekuboorera (MWD) chakaiswa mukati macho, zvichipa nzvimbo yekuyera yakachengeteka uye yakagadzikana yeMWD.

Pane mutsetse wepamusoro-soro pamadziro ekunze ehanger sub, unoshandiswa kugadzirisa divi repamusoro reprogressive cavity drill (PCD) uye kuyera kukosha kweoffset pakati peMWD nePCD. Rusvingo rwemukati rwehanger rune kiyi inobuda, iyo inoshandiswa kana MWD yaiswa. Kana MWD isiri kushandiswa, kungwarira kunofanira kupihwa pakubvisa hanger sub kutanga kudzivirira kiyi kuti isasukwe nekuda kwekuyerera kwakanyanya (izvo zvinogona kukonzera tsaona dzemugomba).

VIII. Chirongo

Basa rayo guru nderekuchengetedza kushanda zvakanaka kwe bit ne drill string, uye kubatsira kubvisa paipi yakanamira kana paipi yanamira.

IX. Joint Inochinjika

Basa rayo guru nderekuchengetedza chirongo uye kuwedzera kusimba kwetambo yekuboorera panguva yekuboorera.
