1.Perforation mānoanoa
ʻO ka helu o nā perforations i kēlā me kēia mika o ka lōʻihi. Ma lalo o nā kūlana maʻamau, no ka loaʻa ʻana o ka mana hana kiʻekiʻe e pono ai ke kiʻekiʻe o ka perforation density, akā i ke koho ʻana o ka perforation density, ʻaʻole hiki ke palena ʻole e hoʻonui i ka density, pono e noʻonoʻo i kēia mau mea:
Hiki ke hoʻopōʻino maʻalahi ka nui o ka puka.
ʻOi aku ka nui o ka nui o ka lua, he kiʻekiʻe ke kumukūʻai;
ʻO ka nui o ka nui o ka puka e paʻakikī i nā hana e hiki mai ana.
Ke liʻiliʻi loa ka pore density, ʻike ʻia ka piʻi ʻana o ka huahana ke hoʻonui ʻia ka pore density. Akā i ka piʻi ʻana o ka nui o ka puka i kekahi waiwai, ʻaʻole maopopo ka hopena o ka puʻu haʻahaʻa i ka ratio huahana. Hōʻike ka ʻike i ka wā o ka nui o ka puka he 26 ~ 39 mau puka / m, e hoʻonui ʻia ka mana hana ma ke kumukūʻai haʻahaʻa.
2. Anawaena puka
He mea nui e hōʻike ana i ka nui o ka perforation. ʻO ka nui o ka perforation ma ke ʻano o 5 a 31mm (0.2 a 1.23in), e pili ana i ke ʻano o ka perforation a me ka nui o ka uku. Me ka nui like o nā pū, ʻoi aku ka liʻiliʻi o ka puka perforation o ka perforation hohonu hohonu, a ʻoi aku ka nui o ka puka nui. ʻO ka nui o ka nui o nā pū, ʻoi aku ka nui o ka puka perforation.
ʻO ke kumu ʻē aʻe e pili ana i ka aperture, ʻo ia ka wehe ʻana ma waena o ka pū perforating a me ka pahu. ʻOi aku ka maikaʻi o ka hoʻohālua ʻana i ka wā i waena o ka luawai ka pū puhi. I ka hana hoʻoheheʻe ʻana, pono ia e hana i nā hana kūpono e mālama ai i ka pū puhi i waenakonu o ka luawai.
3. Māhele
Ua kapa ʻia ka Angle ma waena o ʻelua perforations pili ʻo ka ʻāpana Angle. He hopena nui ka Phase i ka huahana. I kēia manawa, ʻeono mau ʻāpana perforating maʻamau o 0°, 45°, 60°, 90°, 120° a me 180°. I ka hoʻokumu anisotropic, piʻi nui ka huahana i ka wā e hoʻololi ai ka Angle māhele mai 180 ° a i 0 ° a i 90 °, akā ʻaʻole loli nui ka huahana i ka wā e hoʻololi ai ka Angle māhele ma waena o 0 ° a me 90 °.
Hōʻike ka nui o nā hoʻokolohua a me nā noi āpau i ka ʻaila ʻaila i ka haʻahaʻa haʻahaʻa loa i ka wā o ka lua o 0 °. Ke 120 ° a me 180 ° ka pae, aia ka mana hana i waenakonu; Kiʻekiʻe iki ma ka pae 45°; Ke 60 ° a me 90 ° ka pae, ʻoi aku ka kiʻekiʻe o ka hana hana
4. Ka hohonu komo ʻana o ka perforation
E pili ana i ka lōʻihi o ke kahawai perforation. Hoʻoholo ʻia ka hohonu o ke komo ʻana o ka perforation e ke ʻano o ka hoʻolālā perforation charge a me ka nui o nā pū. ʻO ke ʻano o ke komo hohonu ʻana i ka uku nui, lōʻihi ka hohonu o ke komo ʻana, ʻo ka hohonu o ke komo ʻana ma ke ʻano o 146 ~ 813mm, a piʻi ka hohonu o ke komo ʻana me ka piʻi ʻana o nā pū. Piʻi ka ratio productivity o ka ʻaila Wells me ka piʻi ʻana o ka hohonu perforation, akā e piʻi mālie ke ʻano o ka ratio productivity, ʻo ia hoʻi, ke piʻi ka hohonu o ka lua i kekahi waiwai, ʻaʻole e piʻi nui ka ratio productivity.
