1.Kodi ntchito ya downhole ndi chiyani?
Kugwira ntchito ku Downhole ndi njira yaukadaulo yowonetsetsa kuti zitsime zamafuta ndi madzi zikuyenda bwino pakafukufuku ndi chitukuko. Mafuta ndi gasi wokwiriridwa masauzande kapena masauzande a mita pansi pa nthaka ndi zinthu zapansi panthaka. Mafuta amtengo wapataliwa amakumbidwa kudzera m'miyala yobowoleredwa pansi pamiyala yamafuta pansi pamtengo wokwera kwambiri. Pakupanga kwanthawi yayitali, zitsime zamafuta ndi madzi zimakhudzidwa mosalekeza ndi kayendedwe ka mafuta ndi gasi, kotero kuti zitsime zamafuta zikusintha nthawi zonse, kukalamba pang'onopang'ono, ndipo zolephera zamitundu yosiyanasiyana zimachitika, zomwe zimapangitsa kulephera kwabwinobwino. kupanga zitsime zamafuta ndi madzi. Ngakhale anasiya. Choncho, m'pofunika kuchita ntchito zapansi pa zitsime za mafuta ndi madzi zomwe zimakhala ndi mavuto ndi zolephera, kuti zibwezeretsenso kupanga bwino kwa zitsime za mafuta ndi madzi. Ntchito zotsika pansi makamaka zimaphatikizapo kukonza zitsime zamafuta ndi madzi, kukonzanso zitsime zamafuta ndi madzi, kukonzanso nkhokwe ndi kuyezetsa mafuta.
2. Ntchito yosamalira
Pakupanga mafuta ndi jakisoni wamadzi mu zitsime zamafuta ndi madzi, chifukwa cha kupanga mchenga ndi mchere, kuikidwa m'manda, kumamatira mchenga wa pampu, kumamatira mchere, kapena kuyika sera, kuwononga ma valve, kulephera kwa paketi, machubu, kupopera mafuta. Chifukwa cha zifukwa zosiyanasiyana monga kusweka kwa ndodo, zitsime za mafuta ndi madzi sizingapangidwe bwino. Cholinga cha kukonza zitsime zamafuta ndi madzi ndikubwezeretsa kupanga kwabwinobwino kwa zitsime zamafuta ndi madzi kudzera mukugwira ntchito ndi kumanga.
Kukonza chitsime chamafuta ndi madzi kumaphatikizapo: jakisoni woyezetsa chitsime cha madzi, kusintha chisindikizo, kuyeza mbiri ya mayamwidwe amadzi; kuyang'anira pampu yamafuta, kuyeretsa mchenga, kuwongolera mchenga, kukolopa sera, kuthira madzi komanso kukonza ngozi zapabowo ndi ntchito zina.
Pampu yoyendera chitsime chamafuta
Pamene mpope wa mafuta akugwira ntchito m'chitsime, amawukiridwa ndi mchenga, sera, gasi, madzi ndi zinthu zina zowonongeka, zomwe zingawononge zigawo za mpope, kuchititsa kuti pampu iwonongeke, ndipo chitsime cha mafuta chidzasiya kupanga. Chifukwa chake, kuyang'ana mpope ndi njira yofunikira kuti pampu ikhale yogwira ntchito bwino komanso kuti pampuyo ikhale yabwinobwino.
Ntchito yayikulu ya pampu yoyendera chitsime chamafuta ndikukweza ndi kutsitsa ndodo ndi chitoliro chamafuta. Kuthamanga kwa posungira sikuli kwakukulu, ndipo chipangizo chowombera chingagwiritsidwe ntchito poyendetsa pansi. Kwa zitsime zokhala ndi zinthu zakugwa kapena kuthamanga kwapamwamba pang'ono, brine kapena madzi oyera atha kugwiritsidwa ntchito pobowola chitsime chikatsekeredwa, ndipo kupha matope kuyenera kupewedwa.
Chisamaliro chapadera chiyenera kuperekedwa ku ntchito yoyendera mpope: kuwerengera molondola kwa kuya kwa mpope, kuphatikiza koyenera kwa ndodo zoyamwitsa ndi machubu, ndikuyendetsa ndodo zoyamwitsa zoyenerera, machubu ndi mapampu akuzama bwino, ndi zina zotero, zomwe ndizofunikira kwambiri kuti pampu ikhale yabwino.
Jakisoni wamadzi aku Oilfield
Jakisoni wamadzi a Oilfield ndi njira yabwino yolimbikitsira kupanikizika kosanjikiza mafuta, komanso njira yabwino yolimbikitsira kukhazikika kwanthawi yayitali komanso kupanga kwakukulu m'malo opangira mafuta, kuonjezera liwiro lobwezeretsa mafuta komanso kuchira komaliza.
Pambuyo pa dongosolo lachitukuko la jekeseni wamadzi la malo opangira mafuta, kuti mupeze chidziwitso chofunikira monga kuthamanga kwa jekeseni ndi kuchuluka kwa jekeseni pamtundu uliwonse wa jekeseni, siteji ya jekeseni yoyesera iyenera kuperekedwa isanayambe jekeseni wamadzi.
Jakisoni woyeserera: chitsime chamafuta chisanayikidwe mu jakisoni wamadzi, kuyesa ndi kupanga jekeseni watsopano wa chitsime kapena jekeseni wa mafuta kumatchedwa jekeseni woyesera. Makamaka pa chitsime cha jekeseni wamadzi, ndiko kuchotsa keke yamatope, zinyalala, ndi dothi pa khoma la chitsime ndi pansi pa chitsime chatsopano kapena mafuta bwino asanabadwe jekeseni, ndikuzindikira ndondomeko ya mayamwidwe a madzi a jekeseni wa madzi bwino, kuyala. maziko abwino a kukhazikitsa dongosolo la jekeseni wa madzi. Jakisoni woyeserera agawika m'magawo atatu, omwe ndi ngalande zamadzimadzi, kuthamangitsa bwino, jekeseni wotengera ndi zina zofunika jekeseni.
Kutsekereza madzi osankhidwa
Pakukula kwa malo opangira mafuta, madzi omwe atuluka mumafutawo akhudza kwambiri ntchito yachitukuko cha malo opangira mafuta, komanso kuchepetsa kuchira komaliza kwa malo opangira mafuta. Chitsime chamafuta chikatulutsa madzi, choyamba dziwani kuchuluka kwa madzi, ndiyeno gwiritsani ntchito njira yotsekera madzi kuti mutseke. Cholinga cha plugging madzi ndi kulamulira kuyenda kwa madzi mu wosanjikiza madzi kupanga ndi kusintha kayendedwe ka madzi mu madzi osefukira mafuta, kupititsa patsogolo dzuwa kusefukira kwa madzi, ndi kuyesera kuti madzi kupanga oilfield kuchepa kapena. kukhazikika kwakanthawi, kuti apitilize kuchulukirachulukira kwamafuta kapena kupanga kokhazikika ndikuwongolera kuchira komaliza.
Ukadaulo wotsekera madzi ukhoza kugawidwa m'magulu awiri: kutsekera kwamadzi kumakina ndi kutseka kwamadzi kwamankhwala. Kutsekera kwamadzi kwa Chemical kumaphatikizapo kutsekera kwamadzi kosankha komanso kutsekera kwamadzi kosasankha ndikusintha mbiri ya mayamwidwe amadzi a zitsime za jakisoni wamadzi.
1.Kutsekera kwamadzi kwamakinandikugwiritsa ntchito mapaketi ndi zida zothandizira kutsitsa madzi kuti asindikize wosanjikiza wotulutsira madzi pachitsime chamafuta. Kutsekera kwamadzi kwamtunduwu kulibe kusankha. Pakumanga, chingwe cha chitoliro chiyenera kukhala ndi zida kuti chisindikizo champando wapaketi chikhale cholondola komanso cholimba, kuti akwaniritse cholinga chotseka madzi. Njira yotsekera madzi iyi imatha kusindikiza gawo lapamwamba kuti mgodi wapansi, usindikize wosanjikiza wapansi kuti umbale chapamwamba, kapena kusindikiza wosanjikiza wapakati kuti upange malekezero onse awiri ndikusindikiza malekezero awiriwo kuti ukhale wapakati.
2.Chemical madzi pluggingndi kubaya mankhwala plugging wothandizila mu madzi kotuluka wosanjikiza, ndi kugwiritsa ntchito mankhwala katundu wa plugging agent kapena zinthu zopangidwa ndi kusintha kwa mankhwala reactants mu mapangidwe kusindikiza madzi ngalande zotulutsira madzi mapangidwe ndi kuchepetsa lonse madzi kudula. mafuta bwino.
Kutsegula kwamadzi kosankha ndikutulutsa ma polima apamwamba kwambiri kapena zinthu zina zomwe zimatsika ndikulimba zikakumana ndi madzi kuti zipangidwe. Jini la hydrophilic mu polima limakhala ndi kuyanjana komanso kukopa madzi likakumana ndi madzi, ndikukulitsa; imachepa ikakumana ndi mafuta, ndipo ilibe adsorption effect. Zinthu zopanda organic zomwe zimapanga mpweya ndi kulimba zikakumana ndi madzi zimatha kutsekereza njira yotulutsira madzi, ndipo sizipanga mvula kapena kulimba pokumana ndi mafuta.
Kutsekera kwamadzi kosasankha nthawi zambiri kumadalira tinthu tating'onoting'ono kuti titseke pores. Njira yotsekera madzi iyi sikuti imangotchinga njira yamadzi, komanso imatchinga njira yamafuta.
Kusintha bwino mafuta
Popanga zitsime zamafuta, nthawi zambiri chifukwa cha ngozi zapabowo ndi zifukwa zina, zitsime zamafuta ndi madzi sizingapangidwe bwino, makamaka pakachitika zinthu zomata ndi kugwa, kupanga zitsime zamafuta ndi madzi kudzachepetsedwa kapena kuyimitsidwa. , ndipo zikavuta kwambiri, zitsime zamafuta ndi madzi zimachotsedwa. Chifukwa chake, ndikofunikira kuwonetsetsa kuti malo opangira mafuta apangidwe bwino kuti apewe ngozi zapamadzi ndikuthana nazo mwachangu. Zomwe zili mkati mwa kukonzanso zitsime zamafuta ndi madzi ndi izi: kusamalira ngozi zapabowo, kupulumutsa zinthu zovuta kugwa, kukonza ma casing, kusokoneza, ndi zina zambiri.
Kukonzanso zitsime zamafuta ndi madzi ndizovuta, zovuta, komanso zimafuna zambiri mwaukadaulo. Kuphatikiza apo, pali zifukwa zambiri zomwe zimachititsa ngozi zapamadzi, ndipo pali mitundu yambiri ya ngozi zapabowo. Ngozi zodziwika bwino za m'mabowo nthawi zambiri zimagawidwa m'magulu atatu: ngozi zaukadaulo, ngozi zapaipi zokakamira ndi ngozi zakugwa. Mukathana nazo, ndikofunikira kudziwa mtundu wa ngoziyo, kudziwa chomwe chayambitsa ngoziyo, ndikutenga njira zofananira zaukadaulo kuti muyigwire bwino. Ngozi zonse zaukadaulo zimachitika panthawiyi, ndipo zitha kuchitidwa pasadakhale malinga ndi zomwe zidayambitsa ngoziyi panthawi yomanga. Ngozi zomata m'miyendo ndi ngozi zogwa pansi ndi ngozi zazikulu zomwe zimakhudza kupanga kwamafuta ndi zitsime zamadzi. NGOZI. Komanso ndi chiwerengero chachikulu cha ngozi wamba mobisa.
