ʻO ka wehewehe pōkole:

ʻO ke kaʻa Downhole he mea hoʻoneʻe maikaʻi i lalo o ka mana drilling tool, ka mea i hoʻoikaika ʻia e ka wili ʻana i ka wai a me ka uhi ʻana i ke kaomi wai i loko o ka ikehu mechanical. Kahe ka wai lepo mai ka puka o ka paila lepo ma o ka valve by-pass i loko o ke kaʻa. Hoʻopuka kēia kahawai i ka poho puʻe ma waena o ka inlet a me ka puka o ke kaʻa e pana i ke kaʻa e kaʻapuni ana a puni ke koʻi o ka stator, a laila e hoʻouna i ka wikiwiki o ka hoʻololi ʻana a me ka torque i ka bit ma o ke kumu honua a me ka pahu hoʻokele e hoʻokō i ka hana maikaʻi.
Hiki i ka LANDRILL ke hoʻolako i nā ʻano kaʻa lepo lepo e hālāwai me ke ʻano wili like ʻole o nā mea kūʻai aku.

ERT (Ka mānoanoa ʻo Rubber mānoanoa):
Maikaʻi e hoʻololi i ke ʻano o ka hale stator, ʻo ka ʻāpana stator elastomer o Uniform Thickness downhole motor he lahilahi a ʻano like. ʻO nā hiʻohiʻona o ke kaʻa downhole ka lōʻihi pōkole, ka mana kiʻekiʻe, ka hāʻule o ke kaomi kiʻekiʻe, ka wikiwiki o ka hoʻololi haʻahaʻa, ka maikaʻi hoʻoluʻu kiʻekiʻe, ʻo ka hoʻonui ʻana i ka wela, hoʻohana nui ʻia, ʻoi aku ka maikaʻi o ka hana a me ka māmā māmā. ʻO ka mea nui, hiki i nā hiʻohiʻona ke hoʻolōʻihi i ke ola o ka kaʻa downhole a hoʻomaikaʻi i ka hana wili ʻana i ka pūnāwai ultra-hohonu, ʻaoʻao kuhikuhi a me ka wela wela.

Kū'ē i ka wela kiʻekiʻe a me ka ʻaila ma muli o ka lepo:
He kūpono ke kaʻa downhole no ke kiʻekiʻe-mehana, kiʻekiʻe aila kumu lepo ʻōnaehana. Ma nā kūlana o lalo o 180 ° C a me ka aila kiʻekiʻe, loaʻa ka stator elastomer i hoʻonohonoho kūikawā ʻia i nā helu paʻa kiʻekiʻe o ka ikaika ikaika ikaika, ikaika waimaka a me nā waiwai ʻē aʻe. ʻOi aku ka maikaʻi o ka hoʻohana ʻana i ka hopena o ka elastomer pale ʻaila me ka nui kūpono o ka hoʻohana ʻana i ka lepo kiʻekiʻe-mehana, kiʻekiʻe.

Ma hope o ka hoʻoheheʻe ʻana i ka corrosion e hana i ka uhi kūikawā, ʻoi aku ka maikaʻi o ka palaka, ka ʻino a me ka abrasion-resistant ka rotor. A kūpono ke kaʻa downhole no ka manawa lōʻihi i ka wai corrosive.

ʻO ka ʻeli ea:
Hiki i ka hoʻoheheʻe ʻana i ka ea ke pale maikaʻi i ka punawai, hoʻomaikaʻi i ka wikiwiki o ke komo ʻana, hoʻopōkole nui i ka wā wili, mālama i ka nalo ʻana o ka lepo a me ka hāʻule ʻana o ka lua, i kēia manawa ke hoʻohana nui ʻia nei. Hoʻokele ʻia ka ʻenekini hoʻoheheʻe ʻana i ka ea e ke kinoea, foam a me nā wai compressible ʻē aʻe, hāʻawi i ka mana no ka downhole a hoʻokele bit e komo i ka pōhaku. He kiʻekiʻe ke koi o ka ʻenehana hoʻoheheʻe ʻana i ka ea o ka hale hui, ka hoʻolālā laina o ka stator kaʻa a me nā kikoʻī hana.
