Isebenza njani i-TCP

I-Tubing Conveyed Perforating (TCP) I-Bottom Hole Assemblies (BHA) idla ngokuba nentloko yokudubula, i-percussion initiator, imipu egqobhozayo, ixesha elilibazisiweyo lokuqhushumba, umqalisi wesixhobo sokumisela, kunye neplagi. Umqalisi, owaziwa ngokuba yi-CP Detonator, isetyenziselwa ukuqalisa ngokuthembekileyo i-BHA ephantsi komngxuma wokutyhoboza kwishishini leoli negesi.
Amandla empembelelo yoomatshini ukusuka kwintloko yokudubula aguqulwa abe yimveliso yokuqhushumba ngumqalisi ofunekayo ukutshisa umpu wokuqala kwi-BHA. Izixhobo zokutshintshela oomatshini zisetyenziswa phakathi kwemipu yokugqobhoza ukuqalisa iiprimers okanye izitshisi ukwenzela ixesha elilibazisekileyo leziqhushumbisi ukubonelela ixesha elithembekileyo lokutsalela kwiqela elilandelayo lokugqobhoza. Izixhobo zodluliselo eziqhumayo zinokusetyenziselwa ukujoyina iindlela ezingasafunekiyo okanye eziphindiweyo zamandla oololiwe abangasafunekiyo. Amaxesha okulibaziseka achanekileyo aphunyezwa phakathi kwemizuzu emi-5 kunye ne-6 kumngxuma osezantsi kwaye axhomekeke kuBubushushu boMngxuma ongezantsi (BHT). Kumsebenzi osebenza kakuhle ngakumbi, ngaphezulu kwamashumi amathathu (30) ixesha lokulibaziseka kweziqhushumbisi ziye zasebenza ngokuthembekileyo kumdibaniso omnye phakathi kwemipu egqobhozayo. Kumsebenzi weplagi kunye ne-perf, amandla empembelelo yomatshini avela kwintloko yokudubula, okanye isixhobo sokudlulisa, sisebenza umqalisi wezinto ezitshabalalisayo ngokukhawuleza (RDM) esetyenziselwa ukutshisa ngokuthembekileyo iipropellants ekuseteni izixhobo zokuqinisekisa amaxabiso okutsha angaguqukiyo ngaphambi kokwahlulwa kweplagi.

Iinzuzo ze-TCP

Ubuchule bokusebenza. I-TCP ivumela umqhubi wequla ukuba agqobhoze ixesha elide, okanye eliphangaleleyo, izikhewu ngaxeshanye kuhambo olunye ukuya equleni kunokuba enze imitsi emininzi kwi-wireline. Umahluko phakathi kwe-TCP kunye nexesha le-wireline-perforating rig lixhomekeke kubude bexesha kunye nenani le-wireline descents vs ixesha elongezelelweyo lokumisa umtya kunye nokulungiselela iqula lemisebenzi ye-TCP. Nangona kunjalo, i-TCP iveza umpu kwindawo yomthombo ixesha elide kune-wireline perforating, inkxalabo kwimisebenzi yobushushu obuphezulu. I-TCP ivumela umqhubi wequla ukuba enze uvavanyo lokuhamba ngokukhawuleza emva kokugqobhoza. Ubuchwephesha bovavanyo lohlobo lwempembelelo inokubona ubungakanani bomonakalo wequla ngaphambi kokuba kwenziwe utyalo-mali olukhulu kuvuselelo okanye ukupakishwa kwegrabile. Ukongeza kuvavanyo lokunyanzeliswa, ezinye izixhobo zokuvavanya kunye nokugqiba zinokudibaniswa kunye nomtya we-TCP ukubonelela ngovavanyo olubanzi lwe-reservoir ngokukhawuleza emva kokubhoboza.

Ngaphantsi kwePerforating elinganayo. Ukungalingani, okusekwe phakathi koxinzelelo kunye noxinzelelo lwe-wellbore phambi kokuba imipu ye-TCP idutyulwe, idala ukunyuka okukhawulezileyo kunye nokulawulwayo kokubunjwa kolwelo ukuya equleni, okucoca ukubhobhoza kunye nokunyusa imveliso yequla kunye nokutofa.

Ukhuseleko.

Izixhobo zokulawula kakuhle umphezulu zifakwe kwaye zivavanywa phambi kokugqobhoza, ziqinisekisa ukhuseleko olupheleleyo kuzo zonke izigaba zokusebenza kwe-TCP. Izigaba zokusebenza kwe-TCP. IiNkqubo zokuSebenza eziPhezulu. Ubungakanani bompu bukhawulelwe yi-ID yebhokisi, evumela ukusetyenziswa kwezona ntlawulo zinkulu zivumela ukusetyenziswa kwezona ntlawulo zininzi ezinokubakho (ingaba ukungena nzulu okanye uhlobo lokungena-umngxuma omkhulu) kunye nokuxinana kweembumbulu eziphezulu. Imipu inokuphinda iqwalaselwe ukunika eyona ingxinano yokudubula kunye nepateni yesicelo esithile.

Iintlobo zokugqitywa kwe-TCP

Ukugqitywa kweTCP okwethutyana. Ekugqityweni kwe-TCP yesikhashana, izibhamu ziqhutyelwa emthonjeni ekupheleni komtya womsebenzi. Emva kokuba izibhamu zigxothwe, kwaye ixesha livunyelwe ukucocwa kunye nokuvavanya, iqula libulawa kunye nolwelo olupheleleyo olungonakalisi kwaye umtya we-TCP uyasuswa. Iinkqubo zokugqibezela-ukuhlamba umva, ukugalela iasidi, iinkqubo-ukuhlamba umva, ukugalela iasidi, ukuqhekeza, okanye ukupakishwa kwegrabile emva koko kuphunyezwe. Izithuba ezinkulu okanye iMiltizone Wells. Izithuba ezinkulu okanye amaqula apho iindawo ezininzi ezinabileyo zidityanisiweyo zibe ngumtya omnye wemveliso zigqityezelwa ngokufanelekileyo kumsebenzi wethutyana. Emva kokugqobhoza, iqula liyabulawa ngokugqobhoza okungonakaliyo, iqula liyabulawa ngolwelo olungonakaliyo lokugqibezela kwaye umtya wompu uyasuswa. Le nkqubo ibonelela ngeenzuzo ze-TCP ngelixa ibonelela ngenye indlela yokushiya umtya wompu emthonjeni apho unokuphazamisa ukusebenza kwexesha elizayo. Imithombo yeGravel-Packed. Imipu ye-TCP enoxinaniso oluphezulu egcwele imirhumo yokungena emngxunyeni omkhulu isetyenziselwa ukugqobhoza ummandla oza kupakishwa igrabile. Emva kokuba indawo enemingxuma ukuba igrabile igrabile-packed. Emva kokucocwa, iqula liyabulawa ngolwelo olungonakaliyo lokugqibezela kwaye imipu iyalandwa ukuze kuvumeleke ukusebenza kwezikrini kunye nokufakelwa kwepakethi yegrabile. Uvavanyo. I-valve yokulawula kakuhle ingasetyenziselwa ngokubambisana ne-TCP ukubonelela ngokukhawuleza kwindawo ekufutshane ne-wellbore ngokuvavanya ngokunyanisekileyo. Uvavanyo lwe-drill stem oluthatha ixesha elide (DST) lubonelela ngocazululo oluthe kratya lwesakhono sorhwebo sedama ngokuqwalasela iintlobo zolwelo olufunyenweyo kunye namazinga okuqukuqela. Idibaniso ye-DST/TCP iqinisekisa ukucocwa kokugrumba okugqwesileyo kwaye ibonelela ngeempawu zokusebenza kwendawo yokugcina amanzi. Inkqubo ibandakanya izibhamu ze-TCP ezisebenza ngaphantsi kwe-packer efumanekayo kunye nesethi yezixhobo ze-DST. Kwakamsinyane emva kokudutyulwa, iqula liye lavavanywa ngokuqukuqela kwelinye kwaye livaleleke ngaphakathi ukuze kuphuhliswe ulwazi olufunekayo lwedama.

UkuGqibela iTCP esisigxina. KwiZigqibo zeTCP eziSisigxina. Ekugqityweni kwesigxina, izibhamu ziqhutywe ngokugqitywa kwe-TCP esisigxina, izibhamu ziqhutywe ekupheleni komtya wokugqibela wokugqiba. Intloko yequla kunye nezixhobo zokhuseleko zifakwe phambi kokudubula. Imipu isala equleni emva komsebenzi wokugqobhoza kwaye inokuphoswa kwi-rathole ukuba ifunwa.

Njengomvelisi oqeqeshiweyo wemipu yokugqobhoza, imipu yethu yokugqobhoza inokuqinisekisa umgangatho olungileyo kakhulu, kwaye iinjineli zethu zobuchwephesha zinokwenza ucwangciso lweprojekthi olufanelekileyo ngokweemfuno zakho ukukunceda wonge iindleko kunye nokunciphisa umngcipheko. Ukuba unomdla kwi-Vigor's TCP okanye i-WCP perforating guns, nceda unganqikazi ukuqhagamshelana nathi ukuze ufumane izixhobo ezingcono zokugqiba umgangatho kunye neenkonzo zokuthengwa kwempahla.
