Kupanga Chida cha Free Point Indicator (FPI).

Free Point Indicator (FPI) Chida ndi chida chomwe chimazindikiritsa malo aulere mu chingwe chomata cha chitoliro. Chida cha FPI chimayesa kutambasula kwa chitoliro chifukwa cha mphamvu yogwiritsidwa ntchito. Wopanga mawaya amalumikiza chidacho ku chitoliro chotsika, funsani chowongolera kuti chigwiritse ntchito mphamvu yokoka kapena torque, ndipo chidacho chidzawonetsa komwe chitoliro chimayamba kutambasula. Iyi ndiye mfundo yaulere-pamwamba pa izi, chitoliro ndi chaufulu kusuntha, pamene pansi pa mfundo iyi, chitoliro chimakanidwa.

Zida Zachikhalidwe Zaulere Zaulere

Zomwe nthawi zambiri zimatchedwa zida zakale, izi zimakhala ndi choyezera chomwe chimayesa kusintha pang'ono pang'onopang'ono kwa chitoliro, kuponderezana, ndi torque yomwe imayikidwa kuchokera pamwamba ndi chowongolera. Chiyerekezo cha strain, chikakhazikitsidwa, chimangiriridwa kumimba ya chitoliro chamkati, chopanda chotchinga ndi chikoka cha chingwe, ndipo chimatha kuyeza kutambasuka ndi kuzungulira. Komabe, zomwe zimatumizidwa ku gulu lapamwamba zimangoyimira mawonekedwe a chubu pakuya kwa strain gauge. Chifukwa chake, malo angapo oyima masiteshoni amayenera kuchitidwa kuti adziwe bwino kuzama komwe chitolirocho chamamatira. Kuyimitsa kulikonse kumafunikira chowongolera kuti chigwiritse ntchito kutambasula ndi torque kuti mudziwe momwe chitoliro chilili pakuya kwa chizindikiro chaulere.

Zida Za New Generation Free Point

Kumbali ina, zida za Free Point za m'badwo watsopano zimagwiritsa ntchito mwayi wachitsulo wachitsulo. Zidazi zili ndi masensa omwe amasintha kukana kwawo pokhudzana ndi maginito akunja ndi kulemba zotsatira. Imadziwika kuti Halliburton Free Point Tool (HFPT), imazindikiritsa ndikulemba pomwe chitolirocho chimakakamira, kuwonetsa deta mumtundu wa chipika cha digito. HFPT imafuna kugwiritsa ntchito kamodzi kokha kokoka kapena torque pazibowo zowongoka zowongoka kuti zipangitse kupsinjika mu chitoliro, zomwe zimasintha mawonekedwe a maginito a chitoliro pamwamba pa malo omata. Deta iyi imalowetsedwa ndikujambulidwa pa digito, kulola kuwunikanso pambuyo pake ndikuwunika zomwe zatsalira.

Njira Yogwiritsira Ntchito Chida Chatsopano

Njira yogwiritsira ntchito chida chatsopanocho imafuna mipata iwiri yodula mitengo. Chiphaso choyamba chodula mitengo chimalemba maginito okhudza chitoliro chokhala ndi chitoliro chosalowerera ndale (zoyambira). Chiphaso chachiwiri chodula mitengo chimalemba maginito omwe ali ndi mphamvu kapena torque yomwe imayikidwa pa chitoliro. Pamene torque kapena kupsinjika kumagwiritsidwa ntchito ku chitoliro chomwe chimatha kutambasulidwa kapena kugwedezeka, mawonekedwe ake a magnetostrictive amasintha. Ngati gawo la chitoliro silingatambasulidwe kapena kugwedezeka, zotsatira za magnetization zimakhala zosasinthika. Ndi mfundo iyi kuti malo omasuka - kusintha pakati pa chitoliro chomwe chingathe kutambasulidwa kapena kugwedezeka - chimadziwika mosavuta poyerekezera ndi maulendo awiri odula mitengo.

Njira zodziwira mfundo zaulere zam'mbuyomu zimafunikira miyeso yoyima ndi chitoliro chosalowerera ndale ndiyeno kugwiritsa ntchito matalikidwe kapena torque ndipo pamafunika katswiri waluso wowongolera mapaipi pamalo. Njira yatsopanoyi ikungophatikizanso kukuta mipata iwiri yodula mitengo isanayambe komanso itatha chitolirocho chatambasulidwa kapena kutenthedwa.

Komabe, zitsime zopotoka kwambiri kapena zopingasa zingafunike kukokera kwina kapena kutembenuka kwa torque kuti kugogomezera chitoliro chokwanira kuzindikira kuya kwa chitoliro. Kumbukirani, munjira zonsezi, ndikofunikira kuyang'anitsitsa kusintha kwa mphamvu yomwe imagwiritsidwa ntchito komanso kusintha kwa chitoliro (kutambasula, kupindika, etc.). Komanso, njira zonsezi zili ndi malire ake, ndipo zotsatira zake zimatha kukhudzidwa ndi zinthu zosiyanasiyana monga kutentha, kutopa kwa chitoliro, kulemera kwamatope, ndi zina zotero. Choncho, ndikofunikira kutanthauzira zotsatirazo mosamala ndikukambirana ndi akatswiri odziwa zambiri.

Njira yogwiritsira ntchito chida cha FPI ingagwiritsidwe ntchito pamanja ndi njira yowerengetsera yotambasula kuti muchepetse malo omwe akhazikika. Idzachepetsa nthawi ndi nthawi yolembera yofunikira kuti muloze malo enieni ndi chida cha FPI.

Pokakamira podziwika, njira zosiyanasiyana zingagwiritsidwe ntchito kuti amasule chitoliro, kuphatikizapo kugwiritsa ntchito madzi obowola kuti achepetse kuthamanga, kupopa asidi, kugwiritsira ntchito jarring, kapena kudula mapaipi pazovuta kwambiri. Njira yosankhidwa idzadalira momwe chitolirocho chimakhalira.

Chida cha Vigor's Memory Cement Bond chapangidwa makamaka kuti chiwunikire kukhulupirika kwa mgwirizano wa simenti pakati pa casing ndi mapangidwe. Imakwaniritsa izi poyeza matalikidwe a simenti (CBL) pogwiritsa ntchito zolandila pafupi ndi 2-ft ndi 3-ft intervals. Kuphatikiza apo, imagwiritsa ntchito cholandila chakutali pamtunda wa 5-ft kuti ipeze miyeso ya variable density log (VDL).

Kuti muwonetsetse kuwunika kokwanira, chidachi chimagawaniza kusanthula m'magawo 8 aang'ono, ndipo gawo lililonse limakhala ndi gawo la 45 °. Izi zimathandizira kuwunika kokwanira kwa 360 ° kwa kukhulupirika kwa chomangira cha simenti, kupereka zidziwitso zamtengo wapatali pazabwino zake.

Kwa iwo omwe akufuna mayankho makonda, timaperekanso chida cholipiridwa cha sonic Cement Bond Tool. Chida ichi chikhoza kupangidwa kuti chikwaniritse zofunikira zenizeni ndipo chimadzitamandira kamangidwe kameneka, zomwe zimapangitsa kuti chingwechi chikhale chachifupi. Zoterezi zimapangitsa kuti zikhale zoyenera kwambiri pakugwiritsa ntchito kukumbukira mitengo.
