He aha nā hopena o ka perforation Density i ka hopena perforation?

ʻO ka nui o ka perforatione pili ana i ka helu o nā puka i puka i ka mika o ka lōʻihi. Ma keʻano laulā, koi ʻia ka nui perforation kiʻekiʻe e loaʻa ai ka mana kiʻekiʻe, akā i ke koho ʻana i ka density perforation, ʻaʻole hiki ke hoʻonui ʻia ka density no ka manawa pau ʻole, a pono e noʻonoʻo ʻia kēia mau mea:

1. Kamānoanoa perforationhe nui loa, he mea maʻalahi ke hoʻopōʻino i ka casing;

2. Kamānoanoa perforationnui loa a he kiʻekiʻe ke kumukūʻai;

3. Kamānoanoa perforationnui loa, e hoʻopili ana i nā hana e hiki mai ana.

Ke liʻiliʻi loa ka puʻupuʻu perforation, ʻoi aku ka ʻike o ka piʻi ʻana o ka hiki ke hoʻonui i ka nui o ka perforation. Eia nō naʻe, ke piʻi aʻe ka nui o ka perforation i kekahi waiwai, ʻaʻole maopopo ka hopena o ka puʻupuʻu i ka ratio hiki. Hōʻike ka ʻike i ka wā o ka nui o ka puka he 26 ~ 39 mau puka / m, e loaʻa ka mana kiʻekiʻe ma ke kumukūʻai haʻahaʻa.

Ua komo nui ka hui 'oihana o Vigor i ka 'oihana wili aila a me ke kinoea, e 'olu'olu e hilina'i iā Vigor e hā'awi iā 'oe i ka hopena maika'i loa e like me kou makemake, e hā'awi iā 'oe i ka huahana maika'i loa a me ka lawelawe maika'i loa. Inā loaʻa iā ʻoe kekahi mea e pono ai i ka ʻoihana wili ʻaila a me ke kinoea, mai hoʻokaʻulua e launa pū me mākou.
