Dị ka anyị niile maara, nhọrọ nke akụkụ ndị bụ isi nke rotary drilling rig na-ekpebi ozugbo ndụ ọrụ ya. Maka nke a, Sinovo, onye na-emepụta ihe na-eme mkpọtụ, ga-ewebata otu esi ahọrọ bọket ọkpọ.
1. Họrọ bọket ọkpọkọ dịka ọnọdụ ọnọdụ ala
Isi ọrụ nkerotary mkpọpu igwebụ ime oghere n'elu, ihe na-arụ ọrụ bụ nkume nkume. N'ihi na obere omimi nke ikpo oghere rụrụ, nkume enweela mgbagwoju anya mgbanwe nhazi, urughuru size, porosity, cementation, omume na compressive ike site tectonic ije na eke n'ibu na chemical edinam, otú ahụ na-arụ ọrụ ihe nke rotary mkpọpu rig. dị mgbagwoju anya karịsịa.
Iji chịkọta ọnụ, enwere ụdị ndị a.
Dị ka lithology si kwuo, a na-ekewa ya na shale, sandstone, limestone, granite, wdg.
Dị ka usoro ọmụmụ si kwuo, enwere ike kewaa ya na nkume magmatic, nkume sedimentary na nkume metamorphic;
Dị ka ihe eji arụ ọrụ si dị, a na-ekewa ya na nke siri ike, plastik na rụrụ arụ. Ya mere, otu esi ahọrọ akuakuzinwo bit dị ka e guzobere ọnọdụ? Nke a bụ mmeghe nkewa:
(1) Clay: A na-ahọrọ bọket mkpọpu rotary nwere ala otu oyi akwa. Ọ bụrụ na dayameta ahụ dị ntakịrị, enwere ike iji bọket abụọ ma ọ bụ bọket mkpọpu nwere efere ebutu.
(2) Apịtị, oyi akwa cohesive ala na-adịghị ike, ala aja na oyi akwa pebble na cimentation na-adịghị mma na obere urughuru nwere ike iji bọket mkpọpu ala okpukpu abụọ.
(3) Mastic siri ike: bọket mgbapu rotary nwere otu mbata ala (otu na ala abụọ) ma ọ bụ skru kwụ ọtọ nwere ezé ịwụ ka a ga-ahọrọ.
(4) Permafrost oyi akwa: ogologo auger ịwụ na rotary mkpọpu ịwụ nwere ike iji maka ndị nwere obere ice ọdịnaya, na conical auger bit nwere ike iji maka ndị nwere nnukwu ice ọdịnaya. Ekwesiri iburu n'uche na auger bit dị irè maka oyi akwa ala (ma e wezụga sludge), ma a ghaghị iji ya mee ihe na enweghị mmiri dị n'ime ala iji zere nkwụsịtụ nke nsị na-akpata.
(5) nkume cemented na gravels na nkume siri ike ihu igwe: conical spiral bit na okpukpu abụọ ala rotary mkpọpu mmiri ga-akwadebe (otu ọdụ ụgbọ mmiri maka nnukwu urughuru size na okpukpu abụọ n'ọdụ ụgbọ mmiri maka obere urughuru size)
(6) akwa akwa strok: nke nwere obere coring barrel - conical spiral bit - bọket mkpọpu rotary nwere ala okpukpu abụọ, ma ọ bụ buru obere spiral bit kwụ ọtọ - bọket mkpọpu rotary nwere ala abụọ.
(7) Akwa akwa akwa nke nwere ntakịrị ihu igwe: nke nwere cone barrel coring bit - conical spiral bit - bọket mgbapu mmiri okpukpu abụọ. Ọ bụrụ na dayameta ahụ buru ibu, a ga-anakwere usoro mkpọpu ala.
