ʻO ka hoʻoulu ʻana he nui bypass valve

ʻO ka wehewehe pōkole:

Versatility: Hoʻohālikelike me nā ʻano wili ʻana like ʻole, kūpono no ka wili maʻamau, kuhikuhi, a i ʻole ka wili ʻana.

ʻO ka lōʻihi: Kūkulu ʻia me ka ikaika kiʻekiʻe, ke kila i hoʻomaʻamaʻa ʻia i ka wela e kū i nā kūlana downhole paʻakikī.

Pono: E ʻae i ka holo mau ʻana o ka wai a me ka hoʻomaʻemaʻe ʻana i ka lua i ka wā e holo ana i loko a huki paha i waho, e hōʻemi ana i ka manawa hua ʻole.

Palekana: Hoʻemi i nā pilikia e pili ana i ka pipili ʻokoʻa, hāʻule ka lua, a me nā pōʻino wili ʻē aʻe.

Hoʻopilikino: Loaʻa i nā ʻano nui a me nā ʻano milo e hoʻohālikelike i nā kikoʻī drill pipe.

I ka wā o ka wili ʻana, i ka wā i hoʻokō ʻia ai ke kī ʻana o ka pūnāwai a paʻa ka bit bore. Hiki ke wehe ʻia ka valve by-pass e hele i ke kahe wai a me ka pepehi maikaʻi. Ma mua o ka hoʻoheheʻe ʻana i ka hoʻoheheʻe ʻana i ke kinoea, e hoʻonoho ʻia ka valve by-pass ma kahi kokoke a i ʻole ma ka bit.

Ke kiʻekiʻe a paʻa ʻia ke kiʻi maikaʻi a paʻa paha ke kaomi ʻana, hiki ke lawe ʻia kēia mau ʻanuʻu e wehe i ka valve by-pass:

1. E hoʻokuʻu iā Kelly a hoʻokuʻu i loko o ke kinipōpō kila (a i ʻole ka poepoe Nylon) i lawe ʻia e ka mea hana;

2. Hoʻopili me Kelly;

3. E hookomo i ka poepoe i loko o ka waihona ma ke kaa ana o ka pamu;

4. Ke pani ʻia ka wai, hiki ke ʻoki ʻia ka pine shear ma ka hoʻohui ʻana i ka 0.5 ~ 1.5Mpa kaomi ma mua o ke kaomi ʻana o ka paila mua;

5. Ma hope o ka ʻako ʻia ʻana o ka pine, neʻe ka lima o ka sila i lalo e wehe i ka puka hoʻokuʻu a hāʻule iho ke kaomi ʻana i lalo, a laila hiki ke hoʻomaka i ka holo maʻamau a me ka hana pepehi maikaʻi.
