Permanent Packer uye Retrievable Packer

Permanent Packer

Zvimisikidzo zvinotsanangurwa sezvisingaperi zvinobviswa kubva mumatsime nekugaya. Aya ndeekuvaka ari nyore uye anopa tembiricha yepamusoro uye kudzvanywa kwekuita ratings. Iyo diki yekunze dhayamita yemayuniti echigarire inogonesa yepamusoro kumhanya kujeka mukati meiyo casing tambo. Iyo compact kuvaka inovabvumira kutaurirana kuburikidza nezvikamu zvidiki uye kutsauka kunowanikwa mutsime. Yadzo yakakura mukati medhayamita inoita kuti ive yakakodzera kushandiswa netubing tambo dzekuwedzera madhayamita uye mukupedzisa monobore.

Zvinoitwa uye zvinogadzikwa pachishandiswa tambo dzemagetsi, pombi dzekuchera, kana tubing. Kana yangosetwa, zvinhu zvacho zvinoramba kufamba zvichibva kune chero nzira. Wireline marongero anofambisa magetsi kuseta iyo packer kuburikidza nekuputika kwechaji inoputika. Zvadaro chitubu chekusunungura chinoparadzanisa gungano kubva kune packer. Permanent elements akanakira matsime ane high pressure kana tubing load differentials.

Retrievable Packer

Mapaketi anogona kudzoserwa anosanganisira ese ari maviri akajairwa low pressure/low tembiricha (LP/LT) modhi uye zvakanyanya kuomarara kukwira kwepamusoro/tembiricha yepamusoro (HP/HT) modhi. Zvigadzirwa izvi zvinodhura kupfuura zvimiro zvechigarire zvinopa kuita kwakafanana nekuda kwekuoma kwavo kwekugadzira kana zvichibatanidzwa nemidziyo yepamusoro. Nekudaro, zvinhu zvakaita sekureruka kwepacker wellbore kubviswa uye reusability zvinoshanda kudzikamisa chiratidzo chemutengo.

Zvigadzirwa zvakare zvinopatsanurwa kuita assortment yemhando, kusanganisira:

Mechanically set: Kugadzika kunoitwa kuburikidza netubing kufamba kweimwe fomu. Izvi zvinosanganisira kutenderera kana kukwira/kudzika pasi. Uyezve, mutoro unobatanidzwa mukuseta mauniti sezvo huremu hwetubhing huchimanikidza kana kuwedzera chinhu chekuisa chisimbiso. Kudhonza tambo kunoburitsa zvinhu. Izvi zvinonyanya kuwanda mumatsime asina kudzika, akatwasuka ane pressure yakaderera.

Tension-set: Packer zvinhu zvekirasi iyi zvinomisikidzwa kuburikidza nekudhonza tension yakaiswa pane tubing. Slack inoshanda kuburitsa chinhu. Anoshanda zvakanyanya mumatsime asina kudzika ane misiyano yepakati nepakati.

Kutenderera-seti: Aya anoshandisa kutenderera kwechubhu kumichina kuseta uye kukiya muchikamu.

Hydraulic-set: Ichi chikamu chinoshanda kuburikidza nekumanikidza kwemvura ichityaira koni munzvimbo kuseri kwematehwe. Mushure mekugadzika, ingave yekiyi yekiyi kana kuvharirwa kudzvanywa kunoita kuti varambe vakamira. Kutora tubing kunofambisa basa rekuburitsa.

Inflatable: Zvinozivikanwawo sezvinhu zvinozvimba, zvikamu izvi zvinotsamira pakumanikidzwa kwemvura kuti inflate cylindrical machubhu ekuamisa. Anowanikwa mukuyedzwa kwegomba rakavhurika pakuchera matsime ekuongorora uye nesimbisiro yesimende mukugadzira matsime. Iwo akakodzerawo matsime apo vanotakura vanofanira kupfuura nepazvirambidzo vasati vagadzika padhayamita yakakura kwazvo mumakesi kana maburi akazaruka.

Kunyatsotarisa kune dzimwe sarudzo dzakakurumbira dzinotevera pazasi:

Zvinodzoreredzwa tension packer zvinhu zvinotsigira zvepakati kusvika kudzika kudzika kugadzirwa kana majekiseni. Aya ane seti ye unidirectional slips inobata chete casing mumamiriro ezvinhu ane tension mutoro patubhing. Level tubing tension inopa zvinhu simba. Ichi chikamu chinoiswa muchina uye chinoburitswa nechubhu kutenderera. Mazhinji emamodheru anouya nekukurumidzira shear-kuburitswa kana iyo yekutanga nzira yekuburitsa ikatadza.

Tension packers anoshanda mumamiriro ezvinhu apo kudzvinyirirwa pasi kunogara kwakakwira kupfuura annulus pressure iri pachishandiso. Kudzvanyirira uku kunomanikidza zvinhu kuti zvipinde mugungano rekutsvedza kuitira kuchengetedza kushushikana.

Zvinodzoreredzwa compression packer zvinhu zvine fluid bypass zvakanakira yakaderera uye yepakati kudzvanywa mafuta uye gasi kuchera nharaunda pane epakati tembiricha. Mechanical interlock inochengetedza chikamu kubva pakugadzika. Ipo ichimhanya mugomba, tubing kutenderera inomutsa chinhu. Dhova zvidhinha zviri pachinhu chibate panzvimbo uye upe kupokana kunodiwa kuchiseta. Kana iyo interlock yaburitswa, kuderedzwa kwetambo yetubing kunobvumira kuvharwa kweiyo bypass chisimbiso uye kuseta kweanotsvedza. Kushandisa kuenderera mberi-slack-off simba kunogadzira chisimbiso nekusimbisa zvigadzirwa. Kusunungurwa kunoitwa nekungokwevera kumusoro patambo yechubhu.

Sarudzo iyi ine kwaniso yakasarudzika yekushingirira madhindindi akawedzerwa uye tembiricha pane dzimwe tension. Iyo bypass valve inonatsiridza kugona kwemutakuri kuenzana kumanikidzwa kunowanikwa muhubhu uye annulus uye inoita kuti zvive nyore kuburitsa chishandiso. Kuenderera mberi nekumanikidza kana tubing huremu hunodiwa kuti uve nechokwadi chekuti bypass valve inogara yakavharwa. Aya haakodzere matsime ejekiseni kana mashoma vhoriyamu yekumanikidza kurapa maoparesheni.

Kudzoserwa tension / compression set inosimudzira kumhara kwechubhu mukushushikana, kudzvanya, kana kusarerekera. Aya ndiwo anonyanya kufarirwa nemichina yekudzosa mayunitsi nhasi. Ivo vane huwandu hwakakura hwemagadzirirwo ekunetsana, kudzvanya, kana musanganiswa weaya maviri kuseta uye kurongedza chinhu. Kusarudzwa kwemasisitimu uye kusiyanisa zviyero zvinoita kuti zvive zvakakosha muhuwandu hwakawanda hwemamiriro. Nemaseti aya, simba rinopa simba rinovharirwa mukati nemukati yekuvhara michina kusvikira chikwata chasunungurwa nevhavhavhavha. Iyi valve inobatsira mukuenzana zvakare.

Midziyo iyi inoshanda zvakasiyana-siyana kupfuura dzimwe mhinduro uye iripo mune zvese kugadzirwa uye jekiseni mamiriro.

Zvisingaperi uye zvinodzoreredzwa sealbore zvimiro zvakamisikidzwa netambo dzemagetsi kana hydraulics patambo yechubhu. Kugadzika newaya kunopa kukurumidza kukurumidza uye kurongeka nepo imwe-rwendo hydraulic-setting sarudzo dzinobatsira mune imwe chete pass yekuisa. Ivo vanofambisa maitiro ekuseta nematsime akapedzwa kumusoro. Iyi kupatsanurwa inoratidzira yakakwenenzverwa emukati sealbores. Musanganiswa wetubing seal ine elastomeric packing inoumba chisimbiso chinobatanidza tubing yekugadzira uye packer bore. Kumisikidzwa kwezvisimbiso zve elastomeric mubore kunogadzira kuparadzaniswa kwetsime.

Mhando yegungano reLocator inobvumira kufamba kwechisimbiso panguva yekugadzira uye kurapa mashandiro. Anchor assembly type inochengetedza zvisimbiso mukati mepacker bore kudzikamisa tubing kufamba.

Permanent sealbore mhinduro dzinopa kuvandudzwa kwekuita pane zvinodzoreredzwa zvikamu. Ivo vane hukuru hwakaoma mukugadzira zvichiita kuti dzidhure.

Seimwe yemidziyo yakakosha mukupedzisa, mapaketi akaomarara zvakanyanya kugadzira hunyanzvi. Vigor's packers vanogadzirwa vachishandisa yakanyatso kuratidzwa maitiro ekugadzira uye anogara achidzorwa zvakanyatsoenderana neAPI11D1 zviyero panguva yekugadzira maitiro. Izvo chaizvo nekuda kweiyo Vigor kudzora kwakasimba kwemaitiro ayo mhando yechigadzirwa inogara ichipfuura zvinotarisirwa nevatengi, kana iwe uchifarira kuchera kwaVigor uye kupedzisa kugadzira matanda zvigadzirwa, ndapota usazeza kubata neVigor's nyanzvi yehunyanzvi timu kuti uwane zvakanakisa. zvigadzirwa zvemhando yepamusoro uye masevhisi.
