Kupezeka Koyamba kwa Oilfield Oilfield ya 100-Million-Ton ku China's Deep-Ultra-Deep Clastic Rock Formations

Pa Marichi 31, CNOOC idalengeza kuti China idapeza malo opangira mafuta a Huizhou 19-6 okhala ndi nkhokwe zopitilira matani 100 miliyoni kum'mawa kwa South China Sea. Ichi ndi malo oyamba amafuta aku China ophatikizika a m'mphepete mwa nyanja m'miyala yozama kwambiri, zomwe zikuwonetsa kuthekera kotulukira m'malo osungiramo mafuta a hydrocarbon m'mphepete mwa nyanja.

Ili ku Huizhou Sag ya Pearl River Mouth Basin, pafupifupi makilomita 170 kuchokera ku Shenzhen, malo opangira mafuta a Huizhou 19-6 amakhala pamadzi akuya pafupifupi 100 metres. Mayeso opanga awonetsa kutulutsa kwatsiku ndi tsiku kwa migolo 413 yamafuta osapsa ndi ma cubic metres 68,000 a gasi wachilengedwe pachitsime chilichonse. Kupyolera mu ntchito yofufuza mosalekeza, malowa apeza nkhokwe zovomerezeka za nthaka zopitirira matani 100 miliyoni ofanana ndi mafuta.

Pobowola nsanja ya "Nanhai II" ikuchita ntchito zobowola m'madzi a mafuta a Huizhou 19-6.

Pakufufuza kwamafuta ndi gasi m'mphepete mwa nyanja, mapangidwe okhala ndi kuya kwakuya kupitilira 3,500 metres amatchulidwa mwaukadaulo ngati malo osungiramo madzi akuya, pomwe opitilira 4,500 metres amagawidwa ngati madamu akuya kwambiri. Kufufuza m'madera akuya kwambiri apanyanja kumabweretsa zovuta zaumisiri, kuphatikiza kutentha kwambiri / kuthamanga kwambiri (HT/HP) komanso kusinthasintha kwamadzimadzi.

Mapangidwe a miyala yamtengo wapatali, pomwe akugwira ntchito ngati malo osungiramo ma hydrocarbon oyambira m'madzi akuya, amawonetsa mawonekedwe otsika kwambiri. Katunduyu wachilengedwe wa petrophysical amaphatikiza zovuta zaukadaulo pakuzindikiritsa zomwe zingachitike pamalonda, zazikuluzikulu zamafuta.

Padziko lonse lapansi, pafupifupi 60% ya nkhokwe za hydrocarbon zomwe zapezeka kumene m'zaka zaposachedwa zachokera kuzinthu zakuya. Poyerekeza ndi malo osungiramo madzi osaya kwambiri, mapangidwe akuya kwambiri amawonetsa ubwino wodziwika bwino wa nthaka kuphatikizapo kutentha kwa kutentha, kukhwima kwa hydrocarbon, ndi njira zowonjezeretsa hydrocarbon migration. Izi zimathandizira makamaka kutulutsa gasi wachilengedwe komanso mafuta opepuka.

Makamaka, mapangidwewa ali ndi zinthu zambiri zomwe sizinagwiritsidwe ntchito komanso kukhwima kocheperako, zomwe zimawayika ngati madera ofunikira kuti apititse patsogolo kukula kwa nkhokwe zamtsogolo komanso kupititsa patsogolo ntchito yamafuta amafuta.

Malo osungiramo miyala a m'mphepete mwa nyanja omwe ali m'madera akuya kwambiri amatulutsa mchenga ndi dothi panthawi yochotsa mafuta / gasi, zomwe zimapangitsa kuti pakhale chiopsezo cha abrasion, kutsekeka, ndi kukokoloka kwa mitengo ya Khirisimasi ya pansi pa nyanja, manifolds, mapaipi, komanso zipangizo zopangira pamwamba. Makina athu a Highly anti-rosion Ceramic Hydrocyclone Desanding Systems akhala akugwiritsidwa ntchito kwambiri m'minda yamafuta ndi gasi kwazaka zambiri. Tili ndi chidaliro chakuti, kuwonjezera pa mayankho athu apamwamba a desanding, Huizhou 19-6 Oil & Gas Field yomwe yangopezedwa kumene itenganso Njira Yathu Yochotsa Mafuta ya Hydrocyclone Yapamwamba Kwambiri, Compact Injet-Gas Flotation Unit (CFU) ndi zinthu zina.
