Hōʻike nā mea hana ʻaila Landrill i ke alakaʻi koho ʻepekema no nā plug alahaka hiki ke hoʻoheheʻe ʻia

Ma ke kahua paʻakikī o nā hana kahua aila, ke koho ʻana i ka mea kūponoplug alahaka hiki ke hoʻoheheʻe ʻiahe mea nui ia no ke kūkulu ʻana a me ka hana ʻana i ka luawai kūpono. Ua hoʻolauna ʻo Landrill Oil Tools i kahi alakaʻi koho hoʻoholo piha - kumu lāʻau - e hoʻomaʻamaʻa ana i ke kaʻina hana no nā poʻe loea o ka ʻoihana.

KaʻAnuʻu Hana 1: Hoʻohālikelike Mea i Hoʻokele ʻia e ka Mahana

ʻO ka mahana o ke kūkulu ʻana ke kumu nui mua. Hoʻoholo ia i ke kūpaʻa wela a me ka wikiwiki o ka hoʻoheheʻe ʻana o nā mea plug alahaka. No nā wahi haʻahaʻa wela (ma lalo o 60 ℃), kūpono nā hiʻohiʻona Single Slip a i ʻole Compacted Double Slip e like me LZ001, LZ002, a me LZ022. Hāʻawi kēia mau mea i nā ana liʻiliʻi (lōʻihi ≤ 330mm) a me ka hoʻoheheʻe wikiwiki (20 - 40mg·cm⁻²·h). I nā kūlana mahana waena (60 - 90 ℃), ʻālohilohi nā plug Compacted Double Slip a i ʻole Double Slip e like me LZ008, LZ016, a me LZ027, e hāʻawi ana i ka paʻa hoʻopaʻa ʻana i hoʻonui ʻia no nā hiʻohiʻona kaomi waena (≤ 70MPa). ʻO nā lua kiʻekiʻe wela (ma luna o 90 ℃) e kāhea ana i nā hoʻonā Double Slip a i ʻole Full Metal e like me LZ025, LZ030, a me LZ031, e haʻaheo ana i ke kūpaʻa kiʻekiʻe o ke kaomi (85MPa) a me ke kūpaʻa ʻana i ka pala o nā metala āpau.

KaʻAnuʻu Hana 2: Hoʻololi ʻana i ka Paʻakai a me ka Corrosion

Hoʻemi hou aku nā koho i ka paʻakai (ka nui o ka Cl⁻) a me nā wahi ʻino. Kūpono nā lua wai paʻakai haʻahaʻa (ma lalo o 500mg/L) no ka LZ001/LZ002 Series, me ka nui o ka hoʻoheheʻe ʻana o 20 – 40mg·cm⁻²·h. I nā hoʻonohonoho paʻakai kiʻekiʻe (ma luna o 15000mg/L), alakaʻi ka LZ025/LZ028 Series, me ka nui o ka hoʻoheheʻe ʻana o 80 – 120mg·cm⁻²·h. No nā wahi waikawa (pH ≤ 3), ua ʻōlelo ʻia ka Full Metal LZ030 Series, mahalo i kona uhi kūpaʻa waikawa a me ka nui o ka hoʻoheheʻe ʻana o 20 – 300mg·cm⁻²·h ma nā mahana kiʻekiʻe.

KaʻAnuʻu Hana 3: Nā Manaʻo no ka Pahu ʻana a me ke Kaomi

He mea koʻikoʻi nō hoʻi ka nui o ka pahu a me ke kaomi kūkulu. Hoʻopili maikaʻi nā pahu liʻiliʻi (≤ 4″) me ka Single Slip LZ001 (OD 89mm). Loaʻa ka pōmaikaʻi o nā hana kaomi kiʻekiʻe (ma luna o 70MPa) mai ka Double Slip LZ025 (Pressure 85MPa), nona kahi hoʻolālā paheʻe bidirectional no ka ikaika shear 30% kiʻekiʻe. No nā pahu deformed, hōʻoia ka Compacted Double Slip LZ022 (OD 110mm) i ka passability i loko o nā pahu 4.5″.

Ma ka hahai ʻana i kēia kumulāʻau hoʻoholo, hiki i nā hui kahua ʻaila ke koho pololei i nā plug alahaka hiki ke hoʻoheheʻe ʻia, e hoʻomaikaʻi ana i ka hana o ka luawai a me ka hōʻoia ʻana i nā hana maʻalahi ma nā kūlana geological like ʻole. Hāʻawi ke alakaʻi a Landrill Oil Tools i ka ʻoihana e hoʻoponopono i nā pilikia luawai paʻakikī me ka pololei ʻepekema.
