Hoʻopiha ʻia ʻana o ka luawai ʻaila ʻĀkau komohana

I ka makahiki 2022, i mua o ka hopena o ka maʻi maʻi maʻi COVID-19, ua hoʻopau ka Northwest Oilfield Well Completion Management Center i 24 mau papahana, ʻo ia hoʻi nā mea hoʻomalu o ka aila a me ka hoʻomaʻemaʻe ʻana i ka paipu hoʻomaʻemaʻe ʻaila nui, e mālama ana i nā kumukūʻai kūʻai o 13.683 miliona yuan.

I ka wā o ka hoʻohana ʻana i nā paipu aila, ʻoi aku ka liʻiliʻi o ke anawaena o ka paipu ma muli o nā hopena o ka wax, polymers, a me nā paʻakai, e hōʻemi ana i ke kahe ʻaila ʻaila a pili i ka hana ʻaila ʻaila. No laila, ho'oma'ema'e nā hui wili i nā paipu i ho'okahi makahiki. Ma hope o ka mālama ʻana i nā weld seams o nā hui paipu, pono e hoʻomaʻemaʻe i nā paipu.

Ma nā kūlana maʻamau, ʻo nā paipu kila i hoʻohana ʻia e like me nā paipu aila he ʻōpala ma nā ʻaoʻao o loko a me waho. Inā ʻaʻole hoʻomaʻemaʻe ʻia, e hoʻohaumia kēia i ka ʻaila hydraulic ma hope o ka hoʻohana ʻana, e pili ana i ka hana maʻamau o nā mea hydraulic. No laila, pono e wehe i ka ʻōpala ma ka ʻili o loko o nā paipu ma o ka holoi ʻana i ka waikawa. Hiki nō hoʻi i ka holoi ʻana i ka waikawa ke wehe i ka ʻōpala ma ka ʻaoʻao o waho o nā paipu, he mea maikaʻi ia no ka hoʻopili ʻana i ka pena anti-rust i ka ʻili o waho o nā paipu, e hāʻawi ana i ka pale anti-corrosion lōʻihi. Hana ʻia ka holoi ʻana i ka waika me ka hoʻohana ʻana i kahi hopena waika me ka ʻike o 0% a 15%. ʻO Youzhu Company, ma ka hoʻolako ʻana i nā huahana hoʻopaʻapaʻa corrosion: UZ CI-180, kahi mea hoʻopaʻapaʻa ʻawaʻawa kūpaʻa kiʻekiʻe no ka hoʻohana ʻana i ka ʻaila. I ke kaʻina hana o ka acidizing a pickling paha, e hoʻopōʻino ka waikawa i ke kila, a ma ke kiʻekiʻe wela, e hoʻonui nui ʻia ka nui a me ke ʻano o ka corrosion, no laila, i ka hana ʻana o ka ʻaila, ʻo ka pale ʻana i ka corrosion o ka paipu wela kiʻekiʻe. ʻAʻole pili wale i nā pono o ka hoʻohana ʻana i ka ʻaila hinu, akā pili pū kekahi i ka palekana hana. ʻO ke kiʻekiʻe o ka hoʻoheheʻe ʻana i ka waika ma nā pipeline a me nā mea hana e pili ana i ka manawa pili, ka hoʻopaʻa ʻana o ka waikawa a me nā kūlana mahana, a me nā mea ʻē aʻe. Hiki ke hoemi nui ia ka hopena o ka waika ma ke kila ma na wela wela ma ka lalo o ka luawai ma ka hookomo ana i ka UZ CI-180 i ka hui waika. Ua loaʻa iā Youzhu ka mahalo nui ʻia mai ka Northwest Oilfield Management Center no kāna mau papahana i ka hoʻomaʻemaʻe paipu, ka hoʻoheheʻe ʻana i ka wai, a me ka mālama ʻana i nā lako.
