Packer Setting Mechanisms

Weight-Set kana Compression Set Packers

Rudzi urwu rwepakiti runogona kumisikidzwa rwakazvimiririra kana kuti runogona kumhanya mukati sechikamu chakakosha chetambo yechubhu uye kuiswa kana tambo yadzimwa.

Kazhinji uremu seti vanotakura vanoshandisa inotsvedza uye koni gungano iro rinogona kusimudzwa kuti ripe kudzvanywa kwechinhu chisimbiso, kana zvitubu zvekukwevera kana zvidhinha zvekukwesha zvinogona kupinza mukati memadziro ecasing. Nzira dzekuburitsa slips dzinowanzo kuwanikwa uchishandisa J slot mudziyo iyo painobatidzwa inobvumira huremu hwetambo kudzikiswa uye nekudaro kudzvanya chinhu chekuisa chisimbiso. Kuburitswa kwechimwe chinhu kunogona kuwanikwa nekunhonga huremu hwetambo.

Rudzi urwu rwemagadzirirwo ekurongedza anozongove akakodzera kana huremu huchigona kuiswa pane packer izvo zvingave zvisiri izvo mumatsime akarerekera zvakanyanya. Uye zvakare, mutakuri anozoregedza kana yakakwira-kumanikidza musiyano uripo kubva pazasi pepakiti.

Compression-set packers kazhinji inoda 8,000 kusvika 14,000 pondo mashoma ekuseta masimba pazvinhu (packer element durometer uye tembiricha pakudzika kwakadzika zvinofanirwawo kutariswa). Izvi zvinogona, hongu, kuva dambudziko pasi pemamita 2,000 kubva pakudiwa kwepombi yekuboora huremu husina mubvunzo zvichienderana nehukuru hwepakiti uye saizi yechubhu / uremu netsoka.

Tension Setting Packers P

Iri rudzi rwepacker rinonyatsoita huremu set packer inomhanya yakananga pasi, kureva slip uye cone system iri pamusoro pechinhu chekuisa chisimbiso. Iwo anonyanya kubatsira kune maapplication uko yakakwira pasi gomba kudzvanywa uye nekudaro mutsauko wekumanikidza kubva pazasi pepakiri uripo. Mamiriro ezvinhu aya anoitika mumatsime ejekiseni remvura, uko kudzvanywa kwejekiseni kunozobatsira mukuchengetedza iyo packer. Kuchengetedza kunofanira kutorwa kuve nechokwadi chekuti chero tembiricha inowedzera mutambo uye nemhedzisiro yekuwedzera tambo haipe simba rinokwanisa kusunungura mutakuri.

Sarudzo yakajairika yekupedzisa seti isina kudzika ndeye mechanical- tension-set packer. Izvi zvinodaro nekuti tsime risina kudzika rinowanzoratidza mamiriro ezvehupfumi uye tension-set mechanical inodhura zvishoma pane iyo hydraulic set kana wireline set inodzoserwa mamwe.

Roto-Mechanical Set Packers

Mune rudzi urwu rwepakiti, iyo packer yekumisikidza maitiro inofambiswa netubing kutenderera. Kutenderera kwetambo kana

inomanikidza makoni kutsvedza kuseri kwerinotsvedza uye nekudaro kudzvanya chisimbiso, kana kuburitsa iyo yemukati mandrel zvekuti huremu hwechubhu hunogona kuita pamakoni kumanikidza chisimbiso chinhu.

Hydraulic-Set Packers

Mune rudzi urwu rwepakiti, maitiro ekugadzirisa anoenderana ne hydraulic pressure inogadzirwa mukati metambo iyo inoshandiswa ku:

●tyaira piston kuti iite kufamba kweiyo slip uye cone system nekudaro inosanganisira chisimbiso chinhu, kana neimwe nzira.

●actuate seti yekumusoro inotsvedza mupakiti iyo inozogadzirisa iyo packer chinzvimbo uye kubvumira kudhonzwa kudhonzwa pane packer uye kumanikidza chisimbiso system.

Muchirongwa chekare, kana piston inofambiswa ne hydraulically yaita kufamba kwekoni, kudzoka kwekoni kunofanirwa kudzivirirwa nemuchina wekuvhara.

Kubvumira iyo hydraulic pressure kuti igadzirwe muchubhu isati yagadzikwa yepakiti, 3 nzira huru dziripo dzekuvhara tubing:

●Kuiswa kweplug isina chinhu senge Baker BFC plug mukati mezamu rakakodzera seBaker BFC rinogara zamu.

●Kushandiswa kwechigaro chinodhura umo bhora rinogona kudonhedzwa pasi netambo yechubhu. Pakuisa overpressure mushure mekugadzika mutakuri, bhora nechigaro zvinogera kunze uye zvinodonha mutsime sump. Imwe dhizaini inoratidzira iyo inokwidziridzwa collet iyo inodzika pasi uye kuwedzera murecess kamwe overpressure inogera mapini, nekudaro ichibvumira bhora kupfuura.

●Iko kushandiswa kweiyo mutsauko yekubvisa sub, inobvumira iyo tubing fluid kuti ibviswe kuburikidza nemadoko pane sub isati yaisa paki. Bhora kana radonhedzwa richagara pane inowedzerwa collet iyo inobvumira kudzvanywa kuti igadzirwe. Kana overpressure ikangoiswa collet inofamba ichidzika pasi uye mukuita kudaro, inovhara vharuvhu yekutenderera uye inoita kuti bhora ridonhe.

Magetsi Wireline Setting Packers

Mune ino sisitimu, kit yakasarudzika yakabatana neanotakura, ine kana isina tailpipe, uye sisitimu inomhanyiswa mugomba pawaya ine yakadzika yekubatanidza chiridzwa senge casing collar locator CCL Pakudzika kwakadzika, magetsi. chiratidzo chinopfuudzwa pasi tambo inobatidza inononoka-kupisa inoputika charge iri musetting tool iyo zvishoma nezvishoma inovaka gasi pressure uye inomisa kufamba kwepiston kudzvanya chisimbiso system.

Iyi mhando ye sisitimu inotungamira kune yakadzama kuseta kudzika tsananguro yepakiti pamwe nekukasira kuseta / yekumisikidza maitiro. Izvo zvisingabatsiri ndiko kuomerwa kwekumhanya kwewaya mumigodhi yakakwira-ekona uye chokwadi chekuti mutakuri anofanira kuiswa zvakasiyana kubva pakuzoiswa kwetubhing.

Zvigadzirwa zveVigor's packer zvinogadzirwa uye zvinogadzirwa zvinoenderana neAPI 11 D1 zviyero, parizvino tinogona kukupa 6 mhando dzakasiyana dzemapaki, parizvino, vatengi vakachengeta yakanyanya kuongororwa kwezvigadzirwa zvedu zvepakiti, vamwe vatengi vakaisa mberi zvakajairwa zvinodiwa, Vigor's tekinoroji mainjiniya uye kutenga mainjiniya vari kutsvaga mhinduro dzakavimbika kune vatengi vedu. Kana iwe uchifarira Vigor's packer zvigadzirwa, kudhirowa uye kupedzisa kutema matanda, kana OEM yakagadziridzwa masevhisi, ndapota usazeza kutibata nesu kune yakanyanya hunyanzvi rutsigiro rwehunyanzvi.
