Mea Hana Hoʻopili Electro-Magnetic Interference (EMIT)
Nā hiʻohiʻona
ʻO ka VIGOR Electro-Magnetic Interference Tool (EMIT) kahi ʻāpana electromagnetic defect scope i hoʻohana ʻia e ana i ka casing a me ka corrosion tubing me ke anawaena o waho o 43mm, holo ka mea hana ma o ka tubing me ka mana kūʻokoʻa e nānā i nā paipu a me 2-3 papa o pahu ma hope ona. Hiki ke loiloi ʻia ke kūpaʻa o ke kaula casing me ka ʻole o ke koi no ka rig workover kumu kūʻai a me ka lawe ʻana i ka manawa o ke kaula paipu.
Hiki i ka EMIT hou o Vigor ke loiloi i ke ana mānoanoa nui a me ka ʻike ʻino o nā paipu concentric ʻehā. Hoʻohui ka mea hana kiʻekiʻe i kahi mea hoʻouna mana kiʻekiʻe, hoʻomaikaʻi i ka hōʻailona-a-noise ratio (SNR) electronics, a me kahi module acquisition kiʻekiʻe loa a me ka algorithm. Hiki ke hoʻohana ʻia kēia ʻano maʻalahi no ka nui o nā noi loiloi ma nā ʻano hoʻāʻo like ʻole.
Nā hiʻohiʻona
Hoʻohana i kahi mea hoʻohui wikiwiki 13-core, hiki ke hoʻopili maʻalahi iā Gamma, CCL, MIT, CBL, downhole eagle eye, a me nā mea hana ʻē aʻe.
Loaʻa no ka nānā ʻana i ka paia o loko a me waho o ka hemahema casing.
Loaʻa no ka ʻike ʻana i ke ʻano o ka pōʻino, e like me ka māwae ākea, māwae kūkū, ʻinoʻino etc.
Loaʻa e ʻike i 3-4 papa o nā paipu.
Hoʻopaʻa hoʻomanaʻo, maʻalahi no ka hana.
Hoʻohālikelike me nā mea hana hole cased ʻē aʻe o Vigor e hoʻopau i ka loiloi pono pono.
Loaʻa i kēia EMIT kahi pūʻulu pōkole ("C") a me kahi pūʻulu o ka lōʻihi ("A"), a lawe i ke kumu o ke ʻano electromagnetic transient. Hoʻouna ka ʻimi hoʻouna i nā pulse electromagnetic ikaika nui i loko o ka pipeline a puni, a laila hoʻopaʻa ka pipeline i ka hoʻohuihui ʻana o nā hōʻailona o kēia manawa eddy e pili ana i ke kumu kino o ka pulse eddy current (PEC), a ua hoʻohana ʻia kēia mau hōʻailona e loiloi i ke kūlana pipeline.
Hoʻopaʻa ka sensor lōʻihi a hiki i 127 mau kaha, a ʻo kona manawa palaho mai ka 1ms a hiki i 280ms. Hoʻopili kēia i ka hōʻailona attenuation wikiwiki o ka hōʻailona mamao mamao mai ka paipu alloy a hiki i ka pahu nui. ʻOi aku ka liʻiliʻi o ke ana ʻana o ka sensor kaapuni pōkole a ʻoi aku ka kiʻekiʻe o ka hoʻonā kū i luna e nānā i ka paipu i loko.
