Hoʻolālā ʻia ia e hoʻemi i ka coefficient o ka friction ma nā wai wili kumu wai a pau, e hoʻohaʻahaʻa i ka torque a kauo i loko o ka luawai.Me kahi hiʻohiʻona wai ʻokoʻa e hoʻohaʻahaʻa i ka hiki no ka pōleʻa ʻana o Bottom-Hole Assembly (BHA), ʻaʻohe hydrocarbons a kūpono me nā wai kumu wai āpau, e komo pū me nā wai brine mono-/divalent.Me ka liʻiliʻi o ka hāʻawi ʻana i nā waiwai rheological o nā ʻōnaehana lepo, ʻaʻole ia e huhū a hiki ke hoʻohui ʻia i ka ʻōnaehana lepo ma o ka hopper hui ʻana a i ʻole pololei i ka ʻōnaehana o ka ʻili i kahi e loaʻa ai ka hoʻouluulu maikaʻi.

7-Pono

1. ʻO ka lubricant kūpono no nā ʻōnaehana lepo kumu wai

2. E hoemi i ke koena o ka friction e hoemi ana i ka torque a me ke kauo

3. ʻAʻole hoʻonui i ka rheology a i ʻole ka ikaika gel

4. Loaʻa i nā mea hoʻohui metala ʻē aʻe e hoʻemi ana i ka manaʻo o ka shale palupalu a paʻa e hoʻopololei i ka bit a me ka BHA.

5. ʻAʻole ia e hoʻohua

6. Biodegradable me ka hydrocarbons ʻole

7. Palena wela ≤200 ℃ (BHCT)
