ʻIke mua o 100-Million-Ton Offshore Oilfield i loko o ka Deep-Ultra-Deep Clastic Rock Formations o Kina

Ma Malaki 31, ua hoʻolaha ʻo CNOOC i ka loaʻa ʻana o Kina i ka ʻaila hinu Huizhou 19-6 me nā mea mālama i ʻoi aku ma mua o 100 miliona mau tona ma ka hikina o ke Kai Kina Hema. ʻO kēia ka mākaʻikaʻi ʻaila mua loa o Kina i hoʻohui ʻia i waho o ke kahakai i nā ʻano pōhaku clastic hohonu hohonu, e hōʻike ana i ka hiki ke ʻimi koʻikoʻi i loko o ka ʻāina hoʻopaʻa wai hohonu hohonu o ka ʻāina.

Aia ma ka Huizhou Sag o ka Mouth Basin o ka muliwai Pearl, ma kahi o 170 mau kilomita mai Shenzhen mai, aia ka Huizhou 19-6 oilfield ma ka hohonu o ka wai o 100 mika. Ua hōʻike ʻia nā hoʻāʻo hana i kēlā me kēia lā o 413 barela aila ʻaila a me 68,000 cubic mika o ke kinoea kūlohelohe i kēlā me kēia luawai. Ma o nā hoʻoikaika ʻimi hoʻomau, ua loaʻa i ka māla i nā mālama ʻāina i hōʻoia ʻia ma mua o 100 miliona tons o ka aila like.

Ke alakaʻi nei ke kahua hoʻoheheʻe "Nanhai II" i nā hana wili ma ka wai ʻaila ʻo Huizhou 19-6.

I ka ʻimi ʻana i ka aila a me ke kinoea i waho, ua hoʻokaʻawale ʻia nā mea kanu me ka hohonu o ke kanu ʻana ma mua o 3,500 mika i loko o nā loko hohonu, aʻo nā mea ma mua o 4,500 mau mika e hoʻokaʻawale ʻia i loko o nā wai hohonu hohonu. ʻO ka ʻimi ʻana i loko o kēia mau kaiapuni moana hohonu hohonu e hōʻike ana i nā luʻi ʻenekinia weliweli, e komo pū ana me nā kūlana wela kiʻekiʻe/kiʻekiʻe (HT/HP) a me nā dynamics wai paʻakikī.

ʻO nā kumu pōhaku Clastic, ʻoiai e lawelawe ana ma ke ʻano he mau waihona wai wai-hydrocarbon mua ma nā wahi wai hohonu, e hōʻike ana i nā hiʻohiʻona haʻahaʻa haʻahaʻa. Hoʻopili nui kēia waiwai petrophysical i nā pilikia ʻenehana i ka ʻike ʻana i nā hoʻomohala ʻoihana ʻaila nui.

Ma ke ao holoʻokoʻa, ma kahi o 60% o nā waihona hydrocarbon hou i ʻike ʻia i nā makahiki i hala iho nei ua loaʻa mai nā kumu hohonu. Ke hoʻohālikelike ʻia me nā waihona wai pāpaʻu waena, hōʻike nā ʻano hoʻokumu hohonu-ultra-hohonu i nā pono kūlohelohe kūʻokoʻa e pili ana i nā hoʻomalu wela-piʻi kiʻekiʻe, kiʻekiʻe o ka hydrocarbon oʻo, a me nā ʻōnaehana neʻe ʻana o ka hydrocarbon proximal. ʻO kēia mau kūlana kūpono loa i ka hanaʻana i ke kinoea maoli a me kaʻailaʻaila māmā.

ʻO ka mea nui, loaʻa kēia mau hoʻokumu i nā kumuwaiwai nui ʻole me ka haʻahaʻa haʻahaʻa haʻahaʻa o ka ʻimi ʻana, e hoʻonoho ana iā lākou ma ke ʻano he wahi hoʻololi koʻikoʻi koʻikoʻi no ka mālama ʻana i ka ulu ʻana o ka wā e hiki mai ana a me ka hoʻonui ʻana i ka hana ʻana i ka ʻoihana ʻaila.

Hiki i nā waihona pōhaku clastic ma waho o ke kahakai ke hana i ke one a me ka lepo i ka wā e ʻohi ai i ka ʻaila/gas, e hōʻeha ana i ka abrasion, clogging, a me ka ʻāʻī ʻana i lalo o nā kumulāʻau Kalikimaka, manifolds, pipelines, a me ka ʻaoʻao o luna. ʻO kā mākou Highly anti-erosion Ceramic Hydrocyclone Desanding Systems ua hoʻohana nui ʻia i nā māla aila a me nā kinoea no nā makahiki. Ke hilinaʻi nei mākou i kēlā, ma waho aʻe o kā mākou mau hoʻonā desanding holomua, ʻo ka Huizhou 19-6 Oil & Gas Field i ʻike hou ʻia e lawe pū i kā mākou High-efficiency Hydrocyclone Oil Removal System, Compact Injet-Gas Flotation Unit (CFU) a me nā huahana ʻē aʻe.
