Musi waNyamavhuvhu 30, China National Offshore Oil Corporation (CNOOC) yakazivisa kuti kugadzirwa kwemafuta emafuta anorema kubva kumahombekombe kweChina kwakapfuura matani 5 miriyoni. Izvi zvinoratidza dombo rakakosha mukushandiswa kwakakura kwemahombekombe anorema mafuta ekudzoreredza tekinoroji masisitimu uye midziyo yepakati, kumisa China senyika yekutanga pasirese kuwana hukuru hwekudzoreredza kudzoreredza kwemafuta anorema ekumahombekombe.
Sekureva kwemishumo, oiri inorema pari zvino inotora chikamu che70% chezvepasi rose zvepetroleum zviwanikwa, zvichiita kuti ive yekutanga kutariswa kwekuwedzera kwekugadzirwa munyika dzinogadzira oiri. Kune yakakwira-viscosity inorema oiri, iyo indasitiri inonyanya kushandisa nzira dzekudzikinura dzekubvisa. Musimboti wemusimboti unosanganisira kubaya kudziya kwepamusoro-soro, kudzvanya kwemhepo mudhishi kupisa mafuta anorema, nekudaro kuderedza viscosity yayo nekuishandura kuita mobile, inotorwa nyore nyore "mafuta akareruka".

Heavy oil imhando yemafuta asina kuchena anoratidzirwa nehigh viscosity, high density, kushomeka kwemvura, uye tsika yekuomesa, izvo zvinoita kuti zviome zvakanyanya kuburitsa. Zvichienzaniswa neminda yemafuta ekumahombekombe, mapuratifomu ekumahombekombe ane nzvimbo shoma yekushandisa uye anounza mutengo wakakwira zvakanyanya. Iyo yakakura-yekupisa kudzoreredza kweoiri inorema saka inopa matambudziko maviri maererano nezvose zvehunyanzvi midziyo uye kugona kwehupfumi. Izvi zvinozivikanwa zvakanyanya sedambudziko rakakura rehunyanzvi uye rehupfumi mukati meindasitiri yesimba repasi rose.
MaChina ekumahombekombe anorema mafuta ekudzoreredza maoiri akanyanya kutariswa muBohai Bay. Mazhinji makuru ekudzoreredza mafuta ekudzoreredza akamiswa, kusanganisira iyo Nanpu 35-2, Lvda 21-2, uye Jinzhou 23-2 mapurojekiti. Pakazosvika 2025, kugadzirwa kwepagore kubva pakudzoreredza kwekupisa kwakange kwatopfuura matani miriyoni 1.3, nekubuda kwegore rose kunotarisirwa kukwira kusvika kumamiriyoni maviri ematani.

Kuti ishandise zvine hungwaru uye zvine hupfumi matura emafuta anorema, CNOOC yakaramba ichiita tsvakiridzo yesainzi uye hunyanzvi hwekuvandudza tekinoroji, ichipayona "yakaderera kuverenga, kuburitsa kwakakwira" theory yekudzoreredza kudzoreredza dzidziso. Iyo kambani yatora yakakura-spacing tsime pateni yekusimudzira modhi inoratidzwa neyakakura-kusimba jekiseni uye kugadzirwa, yakakwirira-inopfungaira mhando, uye synergistic kusimudzira kuburikidza neakawanda-chikamu chinopisa zvinwiwa.
Nekuisa jekiseni yakakwira-calorific steam inowedzerwa nemagasi akasiyana-siyana uye makemikari ejenti, uye inotsigirwa nepamusoro-vhoriyamu inobudirira yekusimudza tekinoroji, nzira iyi inosimudzira zvakanyanya kugadzirwa kwega-tsime. Yakabudirira kugadzirisa matambudziko akamira kwenguva refu mukudzoreredza kwekupisa, senge kuderera kwechigadzirwa uye kurasikirwa kwakanyanya kwekupisa, nekudaro zvichiwedzera kuwedzera kwese kudzoreredza mwero wemafuta anorema.
Sekureva kwemishumo, kugadzirisa mamiriro akaomarara ekudzika kwekushisa kwepamusoro uye kudzvanywa kwemafuta anorema ekudzoreredza mashandiro, CNOOC yakabudirira kugadzira inotungamira pasi rose yakasanganiswa jekiseni-yekugadzira michina inokwanisa kumira 350 degrees Celsius. Iyo kambani yakazvimiririra yakagadzira compact uye inoshanda majekiseni emajekiseni, downhole kuchengetedza kudzora masisitimu, uye inogara kwenguva refu jecha kudzora michina. Pamusoro pazvo, yakagadzira nekuvaka puratifomu yekutanga pasi rose yejekiseni remafuta—”Thermal Recovery No.1″—ichizadza mukaha wakanyanya mukukwanisa kwemidziyo yemafuta anodziya yekuChina yekumahombekombe.

Nekuenderera mberi kwekusimudzira tekinoroji yekudzoreredza tekinoroji uye kutumirwa kwemidziyo yakakosha, kuvakwa kwesimba rekugadzira kwemahombekombe anorema mafuta kudzoreredza kudzoreredza kuChina kwakakwidziridzwa zvakanyanya, zvichitungamira mukuvandudzwa kwedhamu. Muna 2024, kugadzirwa kwemafuta ekumahombekombe kweChina kwakapfuura miriyoni-tani kekutanga. Kusvika pari zvino, kugadzirwa kwekuwedzera kwapfuura matani emamiriyoni mashanu, kuwana hukuru hwekupisa kwemafuta anorema munzvimbo dzemahombekombe.
Mafuta anorema anoratidzirwa nehupamhi hwepamusoro, high viscosity, uye yakakwira resin-asphaltene yemukati, zvichikonzera kusanaya kwemvura. Kubviswa kwemafuta anorema Iyo yaizotakura yakawanda yejecha rakanaka rakasimba nemafuta anorema anotorwa uye mhedzisiro yakaoma yekuparadzanisa pazasi kwerukova system, kusanganisira inogadzirwa kurapwa kwemvura kana hurombo hunogadzirwa mvura yemhando yekurasa. Nekushandisa SJPEE yakakwirira inoshanda sedutu rekuparadzanisa michina, aya akatsetseka zvidimbu zvesaizi kusvika kune serval microns zvichabviswa kubva kune main process system uye kuita kugadzirwa zvakanaka. .
Iine akawanda akazvimirira ezvivakwa patents, SJPEE inopihwa chitupa pasi peDNV/GL-inocherechedzwa ISO 9001, ISO 14001, uye ISO 45001 kunaka manejimendi uye masisitimu ebasa rekugadzira. Isu tinopa yakagadziridzwa magadzirirwo ekugadzirisa, chaiyo chigadzirwa dhizaini, kunyatso kuomerera kune dhizaini yekudhirowa panguva yekuvaka, uye mushure mekugadzirwa kwekushandisa mazano masevhisi kune vatengi mumaindasitiri akasiyana.
Yeduhigh-efficiency cyclone desanders, nekuita kwavo kunoshamisa kwe98% kuparadzanisa, vakawana mukurumbira mukuru kubva kune akawanda epasirese simba hofori. Yedu yepamusoro-soro cyclone desander inoshandisa advanced ceramic kupfeka-resistant (kana inonzi, yakanyanya-anti-ikukurwa) zvinhu, kuwana kubviswa kwejecha kunyatsogona kunosvika 0.5 microns pa98% kurapwa gasi. Izvi zvinobvumira gasi rinogadzirwa kuti ripinzwe mumadziva enzvimbo yemafuta yakaderera iyo inoshandisa gasi rakakanganiswa mafashamo uye inogadzirisa dambudziko rekushomeka kwemvura inogadziriswa uye inowedzera zvakanyanya kupora kweoiri. Kana kuti, inogona kurapa mvura inogadzirwa nekubvisa zvidimbu zve2 microns pamusoro pa98% kuti ibayezve majekiseni mumadziva, ichideredza kukanganiswa kwezvakatipoteredza uku ichiwedzera kugadzirwa kwemafuta-mumunda nehunyanzvi hwekufashamira kwemvura.
SJPEE's desanding hydrocyclone yakaiswa patsime uye mapuratifomu ekugadzira munzvimbo dzese dzemafuta negasi dzinoshandiswa neCNOOC, CNPC, Petronas, pamwe neIndonesia neGulf yeThailand. Iwo anoshandiswa kubvisa zvakaomeswa kubva gasi, zvinwiwa zvemutsime, kana condensate, uye anoshandiswawo mumamiriro ezvinhu akadai sekubvisa kwakasimba kwemvura yegungwa, kudzoreredza kugadzirwa, jekiseni remvura, uye mafashama emvura kuti awedzere kudzoreredza mafuta.
Ehe, SJPEE inopa zvinopfuura kungoita desanders. Zvigadzirwa zvedu, sengemembrane kupatsanurwa - kuwana CO₂ kubviswa mugasi rechisikigo, deoiling hydrocyclone, yepamusoro-mhando compact flotation unit (CFU),uyemulti-chamber hydrocyclone, ose anofarirwa zvikuru.
