1. Nkọwa nke ndị na-akwakọba ihe na RTTS

A na-eji ngwa nchikọta RTTS eme ihe mkpuchi nke e ji igwe rụọ, nke nwere ngwa nchikọta hydraulic. A na-ejikarị ha eme ihe maka mgbawa na ime ka acid dị na ya, mana a pụkwara iji ha mee ihe maka ọrụ dị n'ime olulu mmiri dịka nnwale olulu mmiri, ịgba mmiri, na ịpịcha simenti.

Ngwa ndị na-ebuga ihe n'ime oghere mmiri RTTS bụ ngwa ọrụ pụrụ iche e ji emechi mmanụ, gas, na mmiri n'ime olulu mmiri e tinyere n'ime ya. Ha na-eji ike mpụga eme ka ogologo silinda roba dị mkpụmkpụ ma mee ka dayameta ya dịkwuo elu. Site n'imechi oyi akwa mmanụ na oghere annular, onye na-ebuga ihe n'ime ya na-ekewapụ oyi akwa mmanụ (ma ọ bụ oyi akwa gas/mmiri) n'elu na n'okpuru, na-emezu ebumnuche nke ịnwale olulu mmanụ na gas.

Ngwa ndị na-ebuga ihe n'ime RTTS na-abịa n'ọtụtụ nha, gụnyere 4 1/2 inch, 5 inch, 5 1/2 inch, 7 inch, na 9 5/8 inch. Nha nke ngwa ndị na-ebuga ihe n'ime ya nwere usoro ntụgharị J-slot, ihe ndọda igwe, ahụ onye na-ebuga ihe n'ime ya, na usoro njikọ hydraulic. Usoro njikọ hydraulic na-egbochi onye na-ebuga ihe n'ime ya ka ọ ghara ibuli elu mgbe nrụgide dị n'okpuru onye na-ebuga ihe dị oke elu. N'ihi ọrụ njikọ hydraulic a, ngwaọrụ a dabara adaba karịsịa maka ịnwale olulu mmiri ndị nwere nrụgide dị ala.

Ọnụọgụgụ ihe nlereanya nke ihe mkpuchi ndị ahụ kwekọrọ na nha ha: 4 1/2 inch, 5 inch, 5 1/2 inch, 7 inch, na 9 5/8 inch, na-eme ka ha dabara adaba maka ọrụ oghere dị n'ime nha mkpuchi dị iche iche.

d) Ọ bụrụ na ahụghị mkpọchi ọ bụla n'oge a na-ewepụ ihe mkpuchi ahụ, a ga-adọpụta paịpụ ahụ ọzọ ruo mgbe ọ ruru omimi olulu mmiri ahụ ka e wee nwee ike iwepụ ihe mgbochi alloy dị n'ime mkpuchi ahụ site na mkpuchi ahụ ma bulie ya elu.

5. Uru nke ndị na-akwakọba ihe na RTTS

1. Ngwa RTTS ndị a na-ejikarị eme ihe maka nnwale olulu mmanụ. Ha dabara adaba karịsịa maka olulu mmiri ndị nwere obere nrụgide, obere mmiri na-agafe agafe na olulu mmanụ dị arọ (olulu mmiri ndị na-anaghị agba onwe ha), nakwa maka ọnọdụ ebe mmetọ dị njọ na-eme n'oge a na-egwupụta ihe, na-arụzi simenti, na usoro owuwu ndị ọzọ. N'ihi nnukwu mfu, a chọrọ ọtụtụ olulu mmiri nnwale, a chọkwara ọtụtụ mmiri mmiri na nhazi dị iche iche iji nweta ezigbo paramita mmiri mmiri na nhazi.

2. Ngwa RTTS fracturing nwere ike ime nnwale abụọ nke TCP (Conventional Fracturing) + MFE (Multi-stage Fracturing), ma nwee ike ime nnwale atọ nke TCP (Conventional Fracturing) + MFE (Multi-stage Fracturing) + JET (hydraulic pump drainage), wee mezuo TCP (Conventional Fracturing) + MFE (Multi-stage Fracturing) + JET (hydraulic pump drainage) + acidizing na teknụzụ ọhụrụ anọ ndị ọzọ ejikọtara ọnụ.

3. Ngwa RTTS na-arụ ọrụ dị mfe, dị ọnụ ala, nwere ike ibelata ọnụ ahịa nke ukwuu, ma nwee ezigbo uru akụ na ụba na mmekọrịta mmadụ na ibe ya.

Ngwa ngwungwu RTTS (Nnwale-Ịgbapụta-Ịgbapụta) bụ ngwa ngwungwu mepere emepe, nke a na-eji eme nnwale, ọgwụgwọ, na ọrụ simenti. N'ọtụtụ oge, a na-agba ngwa a n'ime oghere ala na njikọta valvụ na-agagharị. Ahụ ngwa ngwungwu ahụ gụnyere usoro oghere J, mmịpụta igwe, ihe mkpuchi, na mmịpụta hydraulic. Mmịpụta buru ibu na usoro mkpọchi hydraulic na-enyere aka igbochi ngwa ahụ ịbanye n'ime olulu mmiri. Maka ahụ ngwa ngwungwu ≤ 3 1/2 inch (88.9 mm), mmiri drag na-arụ ọrụ usoro oghere J, ebe maka nha ngwa ngwungwu ≥ 4 inch (101.6 mm), a na-eji ngọngọ drag. Ahụ ngwa ngwungwu niile na-abịa ọkọlọtọ na aka uwe oghere J akpaka. Ọ bụrụ na ejiri valvụ na-agagharị, ọ bụ ụdị mkpọchi mepere emepe/kpọchi mechiri emechi, nke enwere ike iji dị ka valvụ na-agagharị na valvụ na-agafe agafe. Mgbe etinyere ngwa ngwungwu ahụ, valvụ ahụ na-emechi emechi na akpaghị aka. N'oge nnwale ma ọ bụ ọrụ simenti, ngwaọrụ mkpọchi ahụ na-egbochi valvụ ahụ imepe. Oghere J kwụ ọtọ dị n'ọnọdụ mkpọchi ahụ mepere emepe dakọtara na oghere J kwụ ọtọ (nhọrọ) dị n'ahụ onye na-etinye ngwugwu ahụ. Njikọ a na-ewepụ mkpa ọ dị ịtụgharị ọkpọkọ ahụ iji mechie valvụ na-agagharị ma ọ bụ tọgharịa ọkpọkọ ahụ mgbe simenti ewepụchara ọkpọkọ ahụ 1.

Atụmatụ:

1. Nhazi zuru oke nke packer mandrel bore na-enye ohere ka a na-awụpụ nnukwu mmiri mmiri site na ngwaọrụ ahụ. Enwere ike ịgba egbe ndị na-agbapụta tubing na ngwaọrụ waya ndị ọzọ site na packer ahụ.
2. Enwere ike ịtọ ma gbanwee ihe mkpuchi ahụ ọtụtụ ugboro site na iji usoro nhazi ọkpọkọ dị mfe.
3. Ihe e tinyere na Tungsten carbide na-enye ike ijide ihe nke ọma ma na-eguzogide iyi nke ọma, nke na-arụ ọrụ nke ọma karịsịa mgbe ejiri ya na mkpuchi siri ike. Nrụgide etinyere na tube ahụ na-eme ka ihe e tinyere na usoro mkpọchi hydraulic rụọ ọrụ.

4. Valvụ mgbasa ozi agbakwunyere nke a na-akpọchi n'ọnọdụ mepere emepe ma ọ bụ nke mechiri emechi n'oge a na-eme nnwale nrụgide ma a na-emepe ya ngwa ngwa mgbe ọ dị mkpa iji kwe ka mgbasa dị n'elu ihe mkpuchi ahụ.

Iji tinye ihe e ji etinye ihe, a na-ebelata ngwa ahụ ntakịrị n'okpuru ebe achọrọ ịtọ ya, wee bulie ya elu ma tụgharịa ya ọtụtụ ntụgharị. Ọ bụrụ na ngwaọrụ ahụ dị n'ala, ọ nwere ike ịdị mkpa naanị ịtụgharị ya ọkara ntụgharị. Agbanyeghị, n'olulu miri emi ma ọ bụ nke gbagọrọ agbagọ, enwere ike ịchọ ọtụtụ ntụgharị site na iji ngwa ntụgharị. Iji nọgide na-enwe ọnọdụ, a ga-ejigide ike aka nri ruo mgbe etinyere ihe ndị e tinyere na ngwa ahụ ma nwee ike ịmalite ibu ibu. A ga-etinye nrụgide nha nha n'akụkụ abụọ nke ihe e ji etinye ihe iji tọhapụ ihe e ji etinye ihe. Mgbe a na-adọpụta ya na tube ahụ, valvụ na-agagharị na-anọgide na-emechi, na-emepụta mgbasa ozi azụ n'ala ihe e ji etinye ihe. Mgbe a na-ebelata tube ahụ, tụgharịa ya n'aka nri, ma bulie ya elu, valvụ na-agagharị na-emepe iji kwe ka mmiri gbasaa n'olulu ahụ.
