1. Ka nui o ka perforation
ʻO ka helu o nā perforations no ka mika o ka lōʻihi. Ma lalo o nā kūlana maʻamau, no ka loaʻa ʻana o ka mana hana kiʻekiʻe loa e pono ai ka nui o ka perforation density, akā i ke koho ʻana i ka perforation density, ʻaʻole hiki ke palena ʻole e hoʻonui i ka density, pono e noʻonoʻo i nā mea aʻe:
Hiki i ka nui o nā puka ke hōʻino maʻalahi i ka casing.
Nui loa ka nui o ka lua, kiʻekiʻe ke kumukūʻai;
ʻO ka nui o nā lua e hoʻopilikia i nā hana i ka wā e hiki mai ana.
Ke liʻiliʻi loa ka nui o nā pore, ʻike maopopo ʻia ka hoʻonui ʻana o ka huahua ke hoʻonui ʻia ka nui o nā pore. Akā, ke piʻi ka nui o nā lua i kahi waiwai, ʻaʻole maopopo ka hopena o ka nui o nā lua ma ka lakio huahua. Hōʻike ka ʻike i ka wā he 26 ~ 39 mau lua/m ka nui o nā lua, e hoʻonui ʻia ka hiki ke hana ma ke kumukūʻai haʻahaʻa loa.
2. Ke anawaena o ka lua
He mea nui ia e hōʻike ana i ka nui o ka perforation. ʻO ka nui o ka perforation maʻamau ma ka pae o 5 a 31mm (0.2 a 1.23in), ma muli o ke ʻano o ka perforation a me ka nui o ka uku. Me ka nui like o nā pōkā, ʻoi aku ka liʻiliʻi o ka puka perforation o ka perforation hohonu-penetrating, a ʻoi aku ka nui o ka perforation puka nui. ʻO ka nui o ka nui o nā pōkā, ʻoi aku ka nui o ka puka perforation.
ʻO kekahi kumu e hoʻopilikia ai i ka puka ʻana, ʻo ia ka hakahaka ma waena o ka pū perforating a me ka pahu. ʻOi aku ka maikaʻi o ka hopena perforating ke kau ka pū perforating ma waenakonu o ka luawai. I ka hana perforating, pono e hana i nā hana kūpono e mālama i ka pū perforating ma waenakonu o ka luawai.
3. Pae
ʻO ke kihi ma waena o nā perforations ʻelua e pili ana ua kapa ʻia ʻo ka phase Angle. He hopena nui ko ka phase i ka huahua. I kēia manawa, aia ʻeono mau phase perforating i hoʻohana pinepine ʻia o 0°, 45°, 60°, 90°, 120° a me 180°. I ke ʻano anisotropic, piʻi nui ka huahua ke loli ka phase Angle mai 180° a i 0° a i ʻole 90°, akā ʻaʻole loli nui ka huahua ke loli ka phase Angle ma waena o 0° a me 90°.
Hōʻike ka nui o nā hoʻokolohua a me nā noi kahua he haʻahaʻa loa ka huahana o ka lua ʻaila ke 0° ka pae o ka lua. Ke 120° a me 180° ka pae, aia ka mana hana ma waena; Kiʻekiʻe iki aʻe ma ka pae 45°; Ke 60° a me 90° ka pae, ʻo ka mana hana ka mea kiʻekiʻe loa.
4. Ka hohonu o ke komo ʻana o ka perforation
Pili i ka lōʻihi o ke kahawai perforation. Hoʻoholo ʻia ka hohonu o ke komo ʻana o ka perforation e ke ʻano o ke ʻano o ka hoʻouka perforation a me ka nui o nā pōkā. ʻO ke ʻano komo hohonu o ka hoʻouka nui, ua lōʻihi ka hohonu o ke komo ʻana, ʻo ka hohonu o ke komo ʻana ma ka laulā o 146 ~ 813mm, a piʻi ka hohonu o ke komo ʻana me ka piʻi ʻana o nā pōkā. Piʻi ka lakio huahua o nā lua ʻaila me ka piʻi ʻana o ka hohonu perforation, akā piʻi mālie ke ʻano o ka lakio huahua, ʻo ia hoʻi, i ka wā e piʻi ai ka hohonu o ka lua i kahi waiwai, ʻaʻole e piʻi nui ka lakio huahua.
