Ngwa nke Cement Retainer

1. Ọrụ Cementi nke mbụ:

Ndị na-ejide ciment bụ ihe dị mkpa na usoro ciment bụ isi n'oge a na-ewu olulu mmiri. Mgbe gwuchara olulu mmiri ahụ, a na-agbaba nchara nchara n'ime oghere ahụ iji gbochie ọdịda ma chebe olulu mmiri ahụ. Oghere anular dị n'etiti casing na olulu mmiri na-ejupụta na ciment iji chekwaa ihe mkpuchi ahụ ma mepụta akara a pụrụ ịdabere na ya. Ndị na-ejide ciment na-arụ ọrụ dị mkpa n'ịhụ na a na-etinye ciment ahụ kpọmkwem ebe ọ dị mkpa, na-egbochi ịkwaga mmiri n'etiti mpaghara olulu mmiri dị iche iche. Ngwa a dị mkpa maka ịmepụta ikewapụ mpaghara yana ịkwalite iguzosi ike n'ezi ihe site na mbido.

2.Ọrụ mmezi:

N'ọnọdụ ebe ọnọdụ olulu mmiri na-agbanwe ma ọ bụ okwu nwere ikewapụ mpaghara na-ebilite n'oge ndụ nke olulu mmiri ahụ, enwere ike iji ndị na-ejide ciment rụọ ọrụ nrụzi. Ọrụ ndị a nwere ike ịgụnye nrụzi n'ọbọ ciment, mwepu nke mpaghara ụfọdụ, ma ọ bụ mgbanwe maka imecha. Ndị na-ejide ciment a na-eji na-arụ ọrụ mmezi na-atụnye ụtụ na-edobe ma ọ bụ iweghachi iguzosi ike n'ezi ihe, na-edozi ihe ịma aka ndị nwere ike ịpụta n'ihi mgbanwe mmiri mmiri ma ọ bụ ọrụ chọrọ.

3.Wellbore iguzosi ike n'ezi ihe na arụmọrụ:

Ngwa n'ozuzu nke ndị na-eji ciment gbanyere mkpọrọgwụ na ntinye aka ha maka iguzosi ike n'ezi ihe na ịrụ ọrụ nke ọma. Site na igbochi nzikọrịta ozi mmiri n'etiti mpaghara dị iche iche, ndị na-ejide ciment na-echekwa nguzozi sitere n'okike nke ọdọ mmiri ahụ, na-ebuli mmepụta, na ibelata ihe egwu dị ka nsonaazụ mmiri ma ọ bụ gas. Ịhụ ikewapụ iche mpaghara site n'iji ciment na-ejide ya bụ ihe kacha mkpa maka ọganihu na-aga n'ihu na arụmọrụ nke olulu mmanụ na gas n'oge ndụ ha niile na-arụ ọrụ.

4. Mwepu mpaghara ahọpụtara:

Ndị na-ejide ciment na-achọtakwa ngwa n'ọnọdụ ebe achọrọ ikewapụ zonal nhọrọ. Dịka ọmụmaatụ, n'ime olulu mmiri nwere ọtụtụ mpaghara na-emepụta ihe, enwere ike idowe ebe nchekwa simenti iji kewapụ otu mpaghara ma na-ekwe ka nrụpụta ma ọ bụ ịgbanye n'ọzọ ọzọ. Nhọrọ a na-ahọrọ na-enyere ndị na-arụ ọrụ aka ijikwa ike nchekwa mmiri nke ọma na ịhazi mmepụta nke ọma iji mezuo ebumnuche arụ ọrụ.

5. Ntụnye aka na mgbaji hydraulic:

N'ime olulu mmiri ndị na-arụ ọrụ mgbawa hydraulic, ndị na-ejide ciment na-arụ ọrụ dị mkpa n'ịwepụ akụkụ dị iche iche nke olulu mmiri. Site n'inye iche iche zonal, ha na-ahụ na a na-eduzi mmiri mmiri na-agbaji agbaji na nhazi nke e bu n'obi, na-eme ka ịdị irè nke usoro mgbawa ahụ dịkwuo mma ma na-ebuli mgbake hydrocarbon.

6. Ngwa Downhole rụchara:

N'oge a na-arụ ọrụ mmecha, enwere ike iji ciment na-ejikọta ya na ngwa mgbada dị ka ndị na-ebu ihe. Ngwakọta a na-eme ka ikewapụ mpaghara dị elu site na ịmepụta ihe mgbochi n'etiti ihe mmecha na olulu mmiri gbara ya gburugburu, na-enye aka n'ịrụ ọrụ nke ọma na nkwụsi ike.

N'ezie, ndị na-eji ciment nwere ngwa dị iche iche n'ofe dị iche iche nke iwu ụlọ olulu mmiri, mmecha, na ntinye aka. Ngbanwe ha na ịdị irè ha na-eme ka ha bụrụ ngwá ọrụ dị mkpa na ngwá ọrụ nke ndị ọkachamara mmanụ na gas, na-enye aka na ọganihu zuru oke na ịrụ ọrụ nke ọma.

Dị ka ndị kasị ọkachamara soplaya nke downhole mkpọ ala na mmecha osisi akụrụngwa na mmanụ na gas ụlọ ọrụ, Vigor's engineering otu ga-enye gị ihe kasị adabara ngwọta na nke mbụ oge; Ndị otu azụmahịa nke Vigor ga-enyere gị aka na ajụjụ ịre ere; Ngalaba njikwa mma nke Vigor ga-eme atụmatụ mmepụta dị mkpa ma na-eduzi nlekọta mmepụta zuru oke tupu etinye ngwaahịa ahụ n'ime mmepụta; Ndị otu QC nke Vigor ga-eduzi nyocha 100% nke ngwaahịa ahụ ozugbo emechara mmepụta ahụ iji hụ na ngwaahịa ahụ nwere ike gboo mkpa ndị ahịa nke ọma.
