Agbanyeghị, echiche a anaghị emezu mgbe niile n'ọnọdụ ụwa n'ezie ebe nhazi ala nwere ike igosipụta ihe onwunwe anisotropic. Usoro ala ọma jijiji Anisotropic, nke na-eburu n'uche ọsọ nke ebili mmiri ala ọma jijiji dabere na ntụziaka, aghọọla ihe dị mkpa na nyocha geophysical na ngwa ụlọ ọrụ mmepụta ihe.
Ịghọta Anisotropy
Tupu anyị eleba anya n'ihe gbasara usoro anisotropic seismic seismic, ọ dị mkpa ịghọta ihe anisotropy pụtara n'ihe gbasara geophysics. Anisotropy na-ezo aka na ndabere nke ihe ndị dị ndụ. N'okwu seismic, nke a pụtara na ọsọ nke ebili mmiri seismic dịgasị iche dabere na ntụziaka ha si agbasa. Anisotropy dị n'okpuru ala ụwa nwere ike ịbụ n'ihi ihe dị iche iche dị na ala dịka nhazi nke mineral, mgbawa, na oyi akwa nke nkume sedimentary.
E nwere ụdị anisotropy dị iche iche nke nwere ike imetụta mgbasa nke ebili mmiri seismic, gụnyere:
1. VTI (Vertical Transverse Isotropy): Nke a bụ ụdị anisotropy kachasị na mpaghara sedimentary, ebe àgwà nkume dị iche iche na-agbanwe agbanwe. Okpokoro sedimentary nwere ike ime ka ebili mmiri na-aga ngwa ngwa karịa kwụ ọtọ.
2. HTI (Isotropy nke na-agbanwe agbanwe kwụ ọtọ): Nke a na-eme mgbe ala dị n'okpuru ala nwere akwa kwụ ọtọ ma ọ bụ mgbawa, na-eme ka ebili mmiri na-aga ngwa ngwa n'akụkụ kwụ ọtọ karịa n'akụkụ kwụ ọtọ.
3. Anisotropy nke Orthorhombic: Nke a bụ ọnọdụ dị mgbagwoju anya karịa ebe ala dị n'okpuru ala nwere usoro nhazi atọ nke otu, nke na-abụkarị n'ihi njikọta nke atụmatụ ala dị iche iche.
4. Anisotropy Triaxial: Nke a na-anọchite anya ụdị anisotropy kachasị n'ozuzu na-enweghị symmetry ọ bụla kpọmkwem, ebe ọsọ ebili mmiri dị iche iche na akụkụ atọ niile.
Ịghọta na ịkọwa ihe gbasara anisotropy dị oke mkpa maka nkọwa ziri ezi nke ala ọma jijiji, nke nwere ike ibute onyonyo ala na atụmatụ akụrụngwa a pụrụ ịtụkwasị obi karị.
Inweta na Nhazi Data Ala Ọma Jijiji
Usoro Anisotropic seismic na-amalite site n'inweta data. Nnyocha nke oge a na-eji ngwa dị elu nke na-ejide data dị elu n'ebe buru ibu. Nke a gụnyere iji isi mmalite dị ka dynamite ma ọ bụ gwongworo vibration iji mepụta ebili mmiri seismic nke na-agafe n'ụwa ma a na-edekọ ha site na usoro geophones ma ọ bụ hydrophones n'elu ma ọ bụ n'ime olulu mmiri.
Nhazi data seismic a iji kọwaa maka anisotropy gụnyere ọtụtụ usoro:
