ThezoboolaMfuti nthawi zambiri imakhala yotsekedwa kwathunthu yopangidwa ndi mutu wa mfuti, thupi lamfuti ndi mchira wamfuti. Ntchito yake ndikuteteza mkatizoboolazipolopolo, zipolopolo zipolopolo, zingwe zophulitsa, zophulitsira ndi zinthu zina zochokera ku kutentha kwakukulu ndi kuthamanga kwa asidi ndi alkali mumgodi. Ndipo chikoka cha chilengedwe chovuta monga kugwedezeka ndi kukhudzidwa panthawi yomanga, kuonetsetsa kuti zida zophulika zimaphulika modalirika, mongazoboolazipolopolo. Kukonzekera kwa thupi lamfuti ndiko makamaka kukonzanso malo osindikizira ndi ulusi, ndipo opanga ena ali ndi vuto lalikulu muzinthu zopangira zida zamfuti kuti apulumutse ndalama. Mlingo wokwanira sikokwanira, ndipo pali kusiyana kwa kulimba kwa ulusi wokwanira ndi kutalika kwa ulusi wokwanira panthawi yokonza. Nthawi zambiri zimapangitsa kuti madzi amadzimadzi alowe m'thupi lamfuti mopanikizika kwambiri, zomwe zimayambitsazoboolachipolopolo ndi chingwe chophulitsa kuti chinyowe ndi kukhudza mphamvu yosonkhanitsira mphamvu, zomwe zimapangitsa kuti pachitike ngozi zakuphana kwamfuti. Kukonzekera kwa mabowo akhungu pa thupi lamfuti ndikofunikanso kwambiri. Kukonzekera kwa mabowo akhungu pa thupi lamfuti ndi dzanja lamanja, ndi m'mimba mwake ¢ 32mm ndi khoma makulidwe osachepera 4mm. Kukonza kwa chofukizira zipolopolo makamaka kumabowo, ndipo kuyikapo pokonza chofukizira zipolopolo ndikofunikira kwambiri. Bowo loyamba liyenera kufanana ndi dzenje lakhungu la thupi lamfuti. Komabe, pali mitundu yambiri yazoboolamfuti, ndi opanga chofukizira zipolopolo ndi osiyana, amene mosapeŵeka kuwononga kwambiri ntchito perforation. Kuvuta kwina, monga zinthu zosayenerera za chimango cha zipolopolo, zomwe zimayambitsa kupindika kwakukulu ndi kupindika kwa chipolopolo, kusanjika kopanda nzeru kwa chimango cha zipolopolo ndi kuphulika, ndi malo olakwika a chimango cha zipolopolo ndi thupi lamfuti. Mapangidwe osasamala a kulemera kwa tsankho ndi kunyamula kwa bomba la chitsime chopingasa, kupatuka kwakukulu kwa mtunda wa dzenje ndi mbali ya gawo ndi zinthu zina. Pa ntchito yoboola, kuphulika kumachoka pa dzenje lakhungu kuti apange mabowo osakhazikika, omwe angapangitse kuti mfutiyo ikhale yosavuta.
Mkhalidwe wabwino wazoboolaopareshoni ndi: zipolopolo perforating kuphulika pa msinkhu womwewo mu mfuti, nthawi kuphulitsa ndi yofanana, chivundikiro chooneka ngati mankhwala anaphwanyidwa nthawi yomweyo, ndi wosanjikiza nthawi kutsegula kwa jet kufika wosanjikiza chandamale ndi chimodzimodzi. . Pokhapokha powonjezera kutalika kwa kuphulika kwa mkati kwa mfuti ya perforating ndizotheka kupanga luso lolowera bwino. Pakukula kwa mafuta,zoboolazipolopolo zokhala ndi pobowo lalikulu, kulowa mozama, ndi kuchulukira kwa dzenje nthawi zambiri zimagwiritsidwa ntchito kuchepetsa kukhuthala kwa thupi lamfuti ndikuwonjezera kutalika kwa kuphulika. Pamene kuphulika msinkhu kumawonjezeka kufika pamlingo wina, zidzakhudza luso lolowera la perforation, zomwe zimapangitsa kuchepa kwa chitukuko cha mafuta. Ndi mtundu wanji wa mfuti womwe uyenera kusankhidwa ndi mtundu wanji wa chipolopolo chomwe chiyenera kusankhidwa, ndipo mawonekedwe a dzenje, kachulukidwe ka dzenje, kabowo, mbali ya gawo ndi kukana kutentha ziyenera kusankhidwa moyenerera. Thezoboolachipolopolo mtundu ndi kuthamanga kwambiri akhoza kuonetsetsa patsogolo bwino ntchito perforating.
Zida monga mphete zosindikizira, mawaya apamwamba, matupi osaphulika ndi zopangira pakati sizinganyalanyazidwezoboolantchito. Kusindikiza mphete zokhala ndi zizindikiro zosiyana za kutentha ziyenera kusankhidwa malinga ndi zitsime. Zipangizo za polyfluororubber ziyenera kugwiritsidwa ntchito pobowoleza ndi kutentha kwambiri. Kwa zisindikizo, mafuta osindikizira otentha kwambiri ndi mafuta a ulusi wotentha kwambiri amagwiritsidwa ntchito nthawi imodzi, ndipo opanga ena amachepetsa njira zogwirira ntchito, ndipo khalidwe la zipangizo ndi losauka. Mlozera wotsutsa kutentha wa mphete yosindikizira sungathe kukwaniritsa zofunikira zomanga, ndipo mavuvu a mpweya ndi osavuta kupanga pa kutentha kwakukulu, zomwe zimakhudza kusindikiza kwa thupi lamfuti. Kutsegula ndi kutseka kwa bokosi la thupi lopanda kuphulika sikophweka, kukula kwa thupi lapakati sikuli yunifolomu, ndipo kukonza waya wa jacking sikolimba, ndi zina zotero, zomwe zidzakhudza kuphulika.
Makampaniwa achititsa ngozi monga kuphulika kwamfuti, kuphulika kwa mfuti, kuphulika kosadutsa, ndi mitembo yamfuti kugwera m'zitsime.
Zolakwa pakukana kwa kutentha ndi zizindikiro za kukana kwa woyambitsa, chingwe choboola, ndi chubu cholimbikitsa chimakhalanso ndi vuto linalakezoboolantchito. Kutentha kwambiri ndi kuthamanga kwambiri kusagwirizana ndi detonating chingwe 170 ℃, 80MP. Detonator 170 ℃, 70MP, pressure initiator 160 ℃/48h, pressure 60MP kapena 220℃/36h, pressure 100MP, detonator ndiye chigawo chofunikira kwambiri chowonetsetsa kuti chiwopsezo cha perforation ndi kuphulika kwabwinobwino. Chipangizo choyambirira cha kutentha kwapamwamba kwambiri chimagwiritsa ntchito zikhomo zometa ubweya umodzi, ndipo piniyo inali yamkuwa H62. Popeza zizindikiro za kutentha ndi kupanikizika kwazitsulo za mapangidwe a pini sizinaganizire kutentha kwapansi ndi kupanikizika, zizindikiro zosiyanasiyana zinachokera ku mayesero apansi. Chikoka cha downhole mikhalidwe kumapangitsa cholakwika kukameta ubweya mtengo waukulu. The detonation kuthamanga chiŵerengero ndi zolondola pa psinjika detonation, amene nthawi zambiri kuposa cholinga detonation kuthamanga, kuchititsa mfuti thupi kulephera kuphulika, ndipo zotsatira zake n'zovuta kulingalira, nthawi zambiri kumabweretsa rework, kukwirira zoopsa zosiyanasiyana zobisika kwa gulu opareshoni, ndi komanso zimakhudza kwambirizoboolantchito.
