Ihe mgbakwunye acidizing

Emebere ihe mgbochi corrosion (CI: 201/203/401) maka nchebe corrosion na gburugburu acidic. Ha dabara maka ụdị acid dị iche iche ma nwee ike iji ya rụọ ọrụ ịsacha pipeline acid.

Youzhu Chem na-enye ndị ọrụ ntụgharị zuru oke na Acidizing Treatments of oil and gas production.designed to help optimally dobe the acid treatment along the wellbore iji nyere aka mepụta usoro ọgwụgwọ kwesịrị ekwesị na atụmatụ iji jide n'aka na ọ bụghị naanị na etinye acid n'ime oge kwesịrị ekwesị.

Corrosion Inhibitor bụ ihe mgbakwunye mmiri na-egwu mmiri nke a na-agbakwunye na mmiri mmiri iji zere ma ọ bụ kpochapụ corrosion nke na-ebute ọnyà na ike ọgwụgwụ nke elu igwe, na-eduga n'oge na mberede ọdịda nke ngwaahịa igwe dị ka mgbawa olu, mkpuchi na ngwa pụrụ iche.

A na-eji ihe mgbochi corrosion eme ihe n'olulu mmanụ na gas kemgbe 1930s. Ụbọchị ndị a, ndị na-egbochi corrosion bụ ndị a maara nke ọma dị ka ụzọ a na-ejikarị achịkwa corrosion, karịsịa na olulu mmiri ndị e ji ígwè carbon mee.

A na-eji ihe mgbochi corrosion eme ihe na ọgwụgwọ acid, dịka matrix acidizing, mgbawa acid, ma ọ bụ na ọgwụgwọ njikwa aja. Mmiri acid dị ukwuu na-eduga na corrosion siri ike mana Youzhu na-enye pọtụfoliyo nke corrosion inhibitors eji dị ka akụkụ nke usoro na-echebe ihe metal dị na olulu mmiri ma ọ bụ n'ime tubing gbakwụnyere site na mmebi nke mmiri ahụ.

Ihe mgbakwunye corrosion Inhibitor na-ezere corrosion na mmepụta nke ọma na usoro nchịkọta nke mmiri metụtara mmepụta mmanụ crude tupu corrosion erichapụ uru n'ihi ụbara ọnụ ahịa.

Ndị na-egbochi ihe bụ ụzọ mbụ nke nchebe megide corrosion. N'ebe mmanụ na gas na usoro mmepụta ihe, ha na-ebelata ihe ize ndụ nke corrosion kpatara CO2, H2S, organic acids, na ndị ọzọ, na-agwa obodo, n'okpuru nkwụnye ego, galvanic, na ụdị corrosion ndị ọzọ nke nwere ike iduga ọdịda akụrụngwa.

A na-eji onye na-atụgharị ihe na-atụgharị elu nwa oge ma ọ bụ ebe a na-agwọ ya n'oge acidizing, nke na-eme ka mmiri mmiri na-atụgharị gaa na ọkwa dị ala nke permeability ma ọ bụ ebe a na-adịghị agwọ ọrịa iji nweta acidizing yiri.

E wezụga nke ahụ, nkà na ụzụ nke hydraulic fracturing na acid fracturing na-adabere na onye na-atụgharị uche iji gbochie ọkpụkpụ ochie, ọkpụkpụ anụ ahụ ma ọ bụ ọkpụkpụ ọhụrụ meghere, na-amanye mmiri na-agbaji agbaji ma ọ bụ acid ka ọ gbanwee ka ịmepụta ọkpụkpụ ọhụrụ, si otú ahụ nweta mgbawa volumetric ma ọ bụ netwọk acid fracturing.

Ndị ọrụ na-atụgharị, nke a makwaara dị ka ndị na-atụgharị kemịkalụ, na-arụ ọrụ site na ịmepụta mmetụta mgbochi nwa oge, ihe na-ahụ maka kemịkalụ nke a na-eji na ọgwụgwọ mkpali iji hụ na ogbugba otu n'ofe ebe a ga-agwọ ya. N'ịkwalite arụmọrụ mkpali, onye nnọchi anya TDA-200 nwa oge bụ akụkụ dị oke mkpa n'akụkụ mkpali nke ọma yana arụrụ ọrụ hydraulic.

Ndị ọrụ na-atụgharị, nke a makwaara dị ka ndị na-atụgharị kemịkalụ, na-arụ ọrụ site na ịmepụta mmetụta mgbochi nwa oge, ihe na-ahụ maka kemịkalụ nke a na-eji na ọgwụgwọ mkpali iji hụ na ogbugba otu n'ofe ebe a ga-agwọ ya. N'ịkwalite arụmọrụ mkpali, onye nnọchi anya TDA-200 nwa oge bụ akụkụ dị oke mkpa n'akụkụ mkpali nke ọma yana arụrụ ọrụ hydraulic.

Iji mee ka mgbake mmanụ dịkwuo mma site n'iji mmiri emelitere viscosity dị ka ihe nchekwa ngagharị. Acid thickener AT350P bụ cationic, nke ukwuu polymer arọ-molekụla arọ nke na-abawanye viscosity nke hydrochloric acid dị ka gelling acid.

Enwere ike iji mmiri ọgwụgwọ viscosified mee ihe n'ụdị ọgwụgwọ dị n'okpuru ala dị iche iche. Ọgwụgwọ ndị dị otú ahụ gụnyere, mana ọnweghị oke na ọgwụgwọ mkpali, ọgwụgwọ njikwa ájá na ngwa ndị ọzọ yiri ya.

A na-ejikarị Surfactant SFT-100 maka mmanụ na gas nke ọma na-agbaji, acidizing na ọrụ ndị ọzọ dị n'okpuru ala, belata esemokwu elu (ma ọ bụ esemokwu interfacial), belata nguzobe nke mgbochi capillary porous, na-eme ka owuwu nke mmiri fọdụrụnụ na-agbaghachi ngwa ngwa na nke ọma, ka ọ dị irè belata mmebi ahụ.

A na-eji surfactants eme ihe n'ọtụtụ ebe na usoro mgbawa hydraulic iji welie mmanụ / gas na-emepụta ma belata oriri ike site na ịchịkwa viscosity kacha mma nke mmiri na-agbaji, na-ebelata esemokwu elu / interfacial n'etiti usoro shale na mmiri na-agbaji, na-enyere aka mgbake mmiri mgbe agbajichara, na-agbanwe mmiri mmiri nke nkume na ibelata esemokwu nke mgbawa.

Ihe emulsifier bụ molekul amphiphilic nke dị obere ma ọ bụ dị elu nke na-achọ ịkwaga ma na-agba ọsọ ngwa ngwa na mmanụ (apolar) na mmiri (polar), na-akwado nhazi nke ntanye na obere ume ike. Ngwakọta ndị a na-ebelata esemokwu ihu ma mepụta ihe nkiri na interface.

Maka oru ngo nke matrix acidizing, Youzhu Chem na-enye kemịkalụ emulsions acid.

Ihe fọrọ nke nta ka ọ bụrụ pasenti 60 nke mmanụ na 40% nke ihe nchekwa gas n'ụwa niile dị n'ime ebe nchekwa carbonate ebe mkpali acid na-esi ike karịa ma e jiri ya tụnyere mmiri mmiri ájá.

Iji emulsified acids n'ọrụ matriks acidizing bụ usoro kachasị dị irè. Mgbe a na-arụ ọrụ, mmiri miri emi, warara dị warara na-emepụta, yana njiri mara mma nke ọma na mgbochi corrosion nke akụrụngwa olulu mmiri.

Na Youzhu Chem Innovations on Corrosion inhibition, etinyere ihe mgbakwunye maka ịkwalite arụmọrụ nke emulsified acid maka ọnọdụ dị iche iche, oke ha, yana ngwọta mmepe.
