Indlela yokukhetha i-Bridge Plug

Amapulaki ebhuloho angamadivayisi akhethekile okuxhuma angasethwa njengamathuluzi okuhlukanisa esikhashana ukuze abuyiswe (abuyiseleke) kamuva noma afakwe njengamathuluzi okuxhuma unomphela nawokuhlukanisa (OkuDrillable).

Angasebenza ngocingo noma amapayipi aklanyelwe ukusetha kuwo noma yikuphiibhokisi noma ishubhu. Futhi, amamodeli ayatholakala asethwe ku-casing kodwa angaqhutshwa ngentambo yeshubhu.

Izicelo ze-Bridge Plug

Ipulaki yebhuloho isetshenziswa lapho:

• Indawo eyodwa noma ngaphezulu enembobo (noma ebuthakathaka) kufanele ivikelwe ngaphansi kwendawo eselashwayo.
• Ibanga phakathi kwendawo eselashwayo kanye naphansi komthombo lide kakhulu.
• Izindawo eziningi kanye nemisebenzi ekhethiwe yokwelapha nokuhlola indawo eyodwa ihlanganisa ukwenza i-asidi,i-hydraulic fracturing,i-casing cementing, kanye nokuhlola.
• Kahle Ukulahlwa.
• Imisebenzi Yesimende Yokulungisa.

Uma kusetshenziswa ipulaki yebhuloho elikhiphekayo, limbozwa ngesihlabathi ngaphambi kokuba udaka lumpontshwe. Ngale ndlela, ivikelwe, futhi usimende oweqile ku-casing ungabhobozwa ngaphandle kokuwulimaza.

Imininingwane

• Ama-P akhethwa kuye ngezinto ezilandelayo:
• Usayizi wekesi, ibanga nesisindo ( 9 5/8″, 7″, .....) okuzosethwa.
• Max Ithuluzi OD.
• Izinga lokushisa.
• Isilinganiso sokucindezela.

Izigaba ze-Bridge Plug & Izinhlobo

Kunezigaba ezimbili eziyinhloko zamapulaki ebhuloho ngokuya ngezicelo zawo:

• Uhlobo Olunwebekayo
• Uhlobo Olubuyisekayo

Futhi, singazihlukanisa ngokwezindlela zokuzihlela:

• Uhlobo lwesethi yolayini wocingo
• Uhlobo lwesethi yomshini

Uhlobo Olunwebekayo

Amapulaki adonsayo ngokuvamile asetshenziselwa ukuhlukanisa i-casing ngaphansi kwendawo ezophathwa. Ziyafana ngomklamo neIsigcina Simende, futhi zingasethwa ku-wireline noma aipayipi lokubhoboza.Lawa mapulaki awakuvumeli ukugeleza kuthuluzi.

Uhlobo Olubuyisekayo

Amapulagi ebhuloho abuyiselekayo asebenza kahle futhi asetshenziswa ngamathuluzi anomsebenzi ofanayo nowohlobo olushayekayo. Ngokuvamile aqhutshwa ohambweni olulodwa (i-Tripping pipe) nama-Retrievable Packers futhi aphinde alandwe kamuva ngemva kokuba usimende sekumbiwe. Ama-opharetha amaningi azobona isihlabathi se-frac noma i-asidi encibilikayoi-calcium carbonate phezu kwepulaki elikhiphekayo ngaphambi kokwenza umsebenzi wokukhama usimende ukuvimbela usimende ukuthi ungahlali phezu kwepulaki yebhuloho elikhiphekayo.

I-Plug ye-Tubing Bridge

Ipulaki yebhuloho ye-thru-tubing (i-TTBP) ihlinzeka ngendlela yokuvala indawo ethile (ephansi) ngaphandle kwesidingo sokubuyisa amashubhu noma ukubulala (indlela yomshini wokumba - indlela yokulinda nesisindo) izindawo zokukhiqiza eziphezulu. Lokhu konga isikhathi nezindleko, futhi ngeke sibe khona isidingo se-rig. Ivala umthombo ngesegimenti yenjoloba enwebekayo enwebeka kakhulu engadlula kushubhu wokuphothula futhi ivalwe ku-casing engezansi.

Ipulaki yebhuloho isethwe nge-hydraulically ukuze ikwazi ukusebenzaamashubhu ahlanganisiwe noma izintambo zikagesi (kusetshenziswa ithuluzi lokusetha izintambo zikagesi ze-thru-tubing). Irabha evuthekayo ingasethwa kuma-ID amaningi okuhlanganisa ipayipi elingenalutho, izimbobo, amalayini e-casing slotted, izikrini zesihlabathi, nezimbobo ezivulekile. Ingase futhi isetshenziselwe ukuvala izindawo eziphansi unomphela noma ukulahlwa kwemithombo unomphela.

Ezinye Izinhlobo Emakethe

I-Iron Bridge Plugs

Amapulagi ebhuloho lensimbi aklanyelwe ukusetshenziswa ezinhlelweni lapho kukhona ukucindezela okuphezulu, izinga lokushisa kanye nezimo ezigugulekayo. Lawa mapulaki anomklamo oqinile futhi angasethwa kusetshenziswa amashubhu asontekile avamile noma ithuluzi lokusetha izintambo zocingo. Ipulaki ine-valve yokudlula yangaphakathi evumela uketshezi ukuthi lugeleze kupulaki uma ludingeka, kuyilapho luvimbela noma yikuphi ukuvuza okungadingeki noma ukugeleza kwamanzi. I-valve yokudlula yangaphakathi iphinde ivumele ukugezwa kwemfucumfucu ngesikhathi sokubuyiswa, okuqinisekisa ubuqotho bepulaki lapho isethiwe.

I-Composite Bridge Plugs

Amapulagi ebhuloho ahlanganisiwe aklanyelwe izinhlelo zokusebenza lapho amazinga okushisa adlulele nezingcindezi zikhona, kodwa angasetshenziswa nasezindaweni ezinomfutho ophansi. Lolu hlobo lwepulaki yebhuloho luthembeke kakhulu futhi ngokuvamile lusetshenziswa ekuqedeni umthombo lapho ikesi kufanele ivikelwe emonakalweni obangelwa uketshezi oluphuma emgodini. Amapulagi ebhuloho ayinhlanganisela afaka isici sokupakisha esihlanganisiwe, esidala uphawu phakathi kwepulaki nebhokisi elizungezile noma ishubhu.

I-WR Bridge Plugs

Amapulagi ebhuloho e-WR aklanyelwe izinhlelo zokusebenza lapho amazinga okushisa aphezulu nezingcindezi zikhona. Zifaka idizayini emisha ezivumela ukuthi zibuyiswe ngokushesha futhi kalula ngaphandle kwamathuluzi engeziwe noma okokusebenza. Ipulaki iqukethe iziliphu eziphezulu, ipulaki mandrel, into yokupakisha, neziliphu ezingezansi. Lapho isetshenziswa, iziliphu ezingenhla zinwebeka odongeni lwe-casing noma ishubhu kuyilapho ama-slip aphansi ewubamba ngokuqinile. Ngesikhathi sokubuyiswa, lezi zingxenye zisebenza ndawonye ukuze kuqinisekiswe ukuthi ipulaki lihlala lisendaweni kuze kube yilapho likhishwa.

I-BOY Bridge Plugs

Amapulagi ebhuloho ka-BOY aklanyelwe ukusetshenziswa ezinhlelweni lapho kukhona khona izingcindezi ezinkulu namazinga okushisa. Lawa mapulaki afaka idizayini eqinile ewavumela ukuthi asethwe kusetshenziswa amashubhu asontekile avamile noma ithuluzi lokusetha izintambo zezintambo. Ipulaki ine-valve yokudlula yangaphakathi evumela uketshezi ukuthi lugeleze kupulaki uma ludingeka, kuyilapho luvimbela noma yikuphi ukuvuza okungadingeki noma ukugeleza kwamanzi. Iphinde ibe ne-elementi yokupakisha edidiyelwe, eyenza uphawu phakathi komzimba wepulaki ne-casing ezungezile noma ishubhu.

Uhlu lwamapulaki ebhuloho akhiqizwa ithimba le-Vigor luhlanganisa amapulagi ebhuloho lensimbi ecijile, amapulagi ebhuloho ayinhlanganisela, amapulagi ancibilikayo ebhuloho kanye nama-Wireline Set Bridge Plugs (Ayabuyiswa). Wonke amapulaki ebhuloho angenziwa ngokwezifiso ngokuya ngezidingo zamakhasimende ukuze ahlangabezane nemvelo eyinkimbinkimbi yendawo yokwakha. Uma unentshisekelo ngemikhiqizo yochungechunge lwepulaki yebhuloho le-Vigor, sicela ungangabazi ukuxhumana nathi ukuze uthole imikhiqizo nezinsizakalo ezisezingeni eliphakeme kakhulu.
