Unoziva here nezveRTTS packer?

RTTS Packer:

Mashoko Akakosha RTTSpaketir ibhegi hombe, rakasungirirwa rinokwanisa kutsungirira kumanikidzwa kwemativi maviri. Rakagadzirirwa kuita mabasa akawanda mumabasa akadai sekuyedza kuumbwa, kuisa acid, uye kusvina simende, zvichiita kuti mabasa akasiyana-siyana apedzwe kamwe chete. Saka, rinoshandiswa zvakanyanya panguva yedu yekugadzira bvunzo. Kunzwisisa kwakadzama kwechimiro chayo chemukati kunobatsira kugadzirisa zviri nani matambudziko angamuka panguva yekushanda nekugadzirisa.

1. Tsanangudzo yeRTTS Packer

RTTS packer ipaki yemhando ye "slip-type packer" yakagadzirwa ne "hydraulic anchor" mudziyo we "hydraulic anchor". Inonyanya kushandiswa pakupatsanura nzvimbo uye kuisa acid mu "zonal isolation" mu "zonal", uye inogona kushandiswawo mu "downhole oil" dzakadai se "weld testing", "water injection", uye "simende pressing". RTTS packer chishandiso chakagadzirirwa kupatsanura nzvimbo dzemafuta, gasi, nemvura mukati me "casing". Inoshandisa simba rekunze kudzvanya "raber element", kupfupisa kureba kwayo uye kuwedzera dhayamita yayo kuti ivhare "annulus" pakati pe "tubing" ne "casing". Izvi zvinopatsanura nzvimbo dziri pamusoro nepasi pe "packer", zvichiita kuti ive yakakodzera kuongororwa kwe "oil" ne "gas well". Saizi dzakajairika dzinosanganisira 4½″, 5″, 5½″, 7″, uye 9⅝″. Saizi yega yega ine "J-slot shifting mechanism", "mechanical slips", "packing element", uye "hydraulic anchor structure". "Hydraulic anchor" inodzivirira "packer" kufamba kumusoro kana "pressure" iri pasi payo yakakwira zvakanyanya. Ichi chinhu chinoita kuti chishandiso chive chakakodzera kuyedzwa muma "wells" asina kuenzana. Ma "packer models" anoenderana nehukuru hwakasiyana-siyana hwe "casing", zvichibatsira mashandiro muma "wellbores" akasiyana.

2. Kuumbwa kweZvivako

Chigadziko ichi chine chinhu chinonamira hydraulic, chinhu chinopakira rabha, zvinotsvedza, uye zvinovhara pakati, pakati pezvimwe zvinhu.

3. Zvinhu Zvikuru

a) Chinongedzo che hydraulic chinoshandiswa nekumanikidzwa kwemachubhu, zvichidzivirira kufamba kwepacker kumusoro.
b) Maslip acho akaparadzaniswa neblock yekudhonza uye anomanikidzwa munzvimbo yekoni kana mupakiri ari panzvimbo isina kugadzikana.
c) Nzira yekuisa J-slot otomatiki inoita kuti zvive nyore kuisa.
d) Magadzirirwo emhando ye casing collar grip ane tungsten carbide inserts uye hydraulic anchor mechanism zvinoita kuti packer igare yakachengeteka.

4. Zvaunofanira Kufunga Nezvekushanda

a) Usati watanga kurongedza, tsime rinofanira kutenderedzwa zvakanaka uye kucheneswa kuitira kuti pasave nemarara anotadzisa kudonha kana kutorwa.
b) Nzira yekugadzika inofanira kushanda zvakanaka uye zvishoma nezvishoma. Kumira kwekukurumidza kunofanira kudzivirirwa kudzivirira kugadzika netsaona.
c) Kudzika kwenzvimbo yacho kunofanira kudzivirira makora emubhokisi.
d) Kana chirongo chikasabuda panguva yekuchitora, tambo yacho inofanira kutorwa yodzikiswa kakawanda kusvika pakadzika kuti ibvise tungsten carbide inserts isati yaburitswa.

5. Mabhenefiti eRTTS Packer

RTTS packer ndeimwe yezvishandiso zvinonyanya kushandiswa pakuedza matsime. Inonyanya kukodzera matsime ane simba shoma, asingapindi mvura yakawanda uye matsime ane mafuta akawanda (matsime asingapindi mvura yakawanda) akakuvara zvakanyanya panguva yekuchera, kuisa simende, kana mamwe mabasa. Matsime akadaro anowanzo rasikirwa zvakanyanya, zvichida nguva yakareba yekuedza uye kutenderera kwemvura kakawanda kuti awane parameters dzemvura nemaumbirwo azvo.

Iyo RTTS packer inobvumira mabasa akasiyana-siyana akabatanidzwa, anosanganisira:
Kuyedzwa kweTCP (Tubing Conveyed Perforating) + MFE (Multi-Flow Evaluator)

Kuyedzwa kweTCP + MFE + JET (hydraulic pump discharge)

Maitiro eTCP + MFE + JET + acidization

RTTS packer iri nyore kushandisa, inodhura zvishoma, inoderedza zvakanyanya mari yekushandisa, uye inopa mabhenefiti akasimba ehupfumi nemagariro evanhu.

RTTS packer ipacker ine simbi yakasungirirwa, inosungirirwa inoshandiswa pakuedza, kurapa, uye kusimudzira simende. Kazhinji, inoshandiswa pamwe chete ne circulating valve assembly. Packer body inosanganisira J-slot mechansim, mechanical slips, packing element, uye hydraulic slips. Ma slips makuru, anorema ari mu hydraulic lock anobatsira kudzivirira kuti tool form isapomperwe mugomba. Kune packer bodies ≤ 3½″ (88.9 mm), drag spring inoshandisa J-slot mechanism, nepo drag blocks dzichishandiswa saizi ≥ 4″ (101.6 mm). All packer bodies ine automatic J-slot sleeve seyakajairwa. Kana circulating valve ikashandiswa, inenge iri ye lock-open/lock-close type uye inoshanda se circulating ne bypass valve. Kana packer yaiswa, valvu inovhara yega panzvimbo yakavharwa. Panguva yekuedza kana pressing cement, lock inodzivirira valvu kuti isapomperwe. Nzvimbo yakatwasuka yeJ iri panzvimbo yakavhurika inoenderana nenzvimbo yakatwasuka yeJ iri mumuviri wepacker (sarudzo). Musanganiswa uyu unobvisa kudiwa kwekutenderedza chubhu kuti ivhare vharuvhu inotenderera kana kudzoreredza packer mushure mekudzinga simende.

Zvimiro:

Dhizaini yakazara ye packer mandrel inobvumira huwandu hwakawanda hwemvura kuti hupfukurwe nepakati pechishandiso. Pfuti dzinofambiswa nemachubhu nezvimwe zvishandiso zvewaya zvinogona kufambiswa nepakati pe packer.

Chigadziko chinogona kugadziriswa uye kugadziriswazve kakawanda kuburikidza nekushandisa machubhu ari nyore.

Tungsten carbide inserts dzinoita kuti pave nekubata kwakanyanya uye kusakara, kunyanya kana paine casing yakasimba. hydraulic lock mechanism inovhurwa nekushandisa kudzvanya nepachubhu.

Vharuvhu inotenderera yakabatanidzwa inovhara munzvimbo yakavhurika kana yakavharwa panguva yekuedza kudzvanywa uye inogona kuvhurwa zviri nyore kana zvichidikanwa kuti ibvumidze kutenderera pamusoro pemupaketi.

Mashandiro:

Kuti uise packer, dzikisa chishandiso pasi pehurefu hwese hwaunoda, wobva wasimudza nekutenderedza kakawanda. Kana chishandiso chiri pasi, hafu yekutenderera chete ingangodiwa. Zvisinei, mumatsime akadzika kana akatsauka, kutenderera kakawanda kunogona kudiwa uchishandisa chishandiso chinotenderera. Kuti uchengetedze nzvimbo, torque yeruoko rwerudyi inofanira kubatwa kusvika maslip emuchina agadziriswa uye huremu hwagona kuiswa. Kumanikidzwa kwakaringana kumativi ese epacker kunodiwa kuti packer ibudise packer. Pakudhonza packer, vharuvhu inotenderera inoramba yakavharwa, zvichiita kuti kutenderera kwese kwese kwese kwepacker kuende pasi pepacker. Kuti uvhure vharuvhu inotenderera kuti iendeswe patsime, dzikisa packer, tenderera kurudyi, uye simudza.
Maitiro Ekugadzirisa uye Kuburitsa RTTS Packer

Sungirira chipfeko chekutakura zvinhu wobva wafambisa ruoko rwekudhonza ruchikwira nekudzika kakawanda kuti utarise kufamba kwezvitsikidzi zvemuchina usati wamhanya mugomba.

Usati wapinda mukati, kiya vharuvhu inotenderera panzvimbo yakavhurika; nzvimbo yeJ inofanirawo kunge yakakiyiwa nerug yakabatirira panzvimbo yeJ-slot hook uye maslip akadzoserwa kumashure,
Paunenge uchimhanya, nzira yekudhonza inotsvedza ichikwira kumusoro, ichiisa maslip emakanika uye ichivhara vharuvhu inotenderera. Kuti udzivise kuvharika kwevharuvhu netsaona, dzikisa tambo, tenderera kurudyi, simudza kusvika panzvimbo yakavhurika, wozotenderera kuruboshwe kuti uivhare—uchingwarira kuti usabvise chubhu.

Kana chishandiso chasvika pahudzamu hwacho hwekuyedza, chidzikise zvishoma pasi pehudzamu hwekuisa, wobva wasimudza kusvika panzvimbo yekuisa.

Dzorera pasi gomba, tenderedza tambo yechubhu kanoverengeka kurudyi—kazhinji hafu yekutenderera ndiyo inodiwa pachishandiso.

Chengetedza simba reruoko rwerudyi uye isa huremu pazvitsikidzi zvemakanika.

Rega kudzikisa tambo, tenderera kuruboshwe, uye bvisa torque yeruoko rwerudyi. Kazhinji, hafu yekutendeuka pamamita mazana matatu yakakwana; usapfuure huwandu hwekutenderera kweruoko rwerudyi hunoshandiswa panguva yekuisa.

Kana torque yeruoko rwerudyi yaiswa, dzikisa tambo papacker kuti ushandise simba rekuisa rinodiwa.

Kuti uvhure vharuvhu rinotenderera uye uchengetedze kudzora kwetsime, tenderedza tambo kurudyi woisimudza; dzvanya pamusoro pechubhu woramba uchisimudza kusvika kutenderera kweropa kwasvika. Bata panzvimbo iyi, pomba mvura, wobva wadzikisa kusvika kumanikidzwa kwabuda ropa, uchibvumira chishandiso kutora huremu. Tendeukira kuruboshwe kuti ubvise torque, wobva waramba uchidzikisa huremu kusvika chipfeko chaiswa nesimba rinodiwa.

Kuti upedze bvunzo uye ubvise chipaketi, tanga waenzanisa kumanikidzwa kwechinhu chinopaketi, wobva wadhonza tambo usingatenderedze kuti vharuvhu inotenderera irambe yakavharwa uye wobva waisa kutenderera kwese kwese kwakatenderedza chipaketi.

Dzikisa chubhu, tenderedza tambo, wobva wasimudza kuti uvhure vharuvhu inotenderera. Chishandiso chinogona kuburitswa mugomba.
