Nzira Dzepasi Pose Dzekudzora Kurasikirwa Kwakanyanya Uye Kwakakwana
Sisitimu yeFoam Wedge Lost Circulation System, inokwanisa kuvhara mapfupa anosvika 40,000 microns, yakashandiswa zvinobudirira neHalliburton mukushandiswa kwenzvimbo munyika mbiri dzeMiddle East (Oman neUAE).
Matambudziko muKuumbwa Kwemapundu/Mapundu Eganda
Kugadzirisa kurasikirwa kwakanyanya kusvika pakuzara kwemasero akatyoka kana kuti akatsemuka kwave kwakaoma kwenguva yakareba, kunyanya kuMiddle East. Zvinhu zvinofamba neropa zvakajairika (LCMs) zvinowanzokundikana nekuda kwekusaziva saizi yekuvhunika kwemasero. Zvisinei, Halliburton's Foam Wedge System, inosanganisa High Fluid Loss Squeeze (HFLS) neReticulated Foam LCM (RFLCM), yakaratidza kushanda zvakanaka, ichitsigirwa nekubudirira kwakaedzwa mumunda.
Kugadzirwa uye kuongororwa kwekurapwa kweLCM kwakavakirwa pabvunzo dzakabudirira dzemurabhoritari, zvichiratidza kuvharwa kwemavanga anosvika 40,000 microns.
HFLS neRFLCM Dual Technology: Laboratory uye Field Results muNyika mbiri dzeMiddle East (Oman neUAE)
Izvi zvinosanganisira hunhu hwekuumbwa kwevhu, saizi yevhu, huwandu uye huwandu hwevhu reLCM, pamwe chete nenzira dzekugadzira uye dzekupomba dzinoshandiswa. Kubudirira kwekushandisa kwakaratidzwa nehuwandu hwekurasikirwa kwevhu risati ragadziriswa uye mushure mekugadzirisa pasi pemamiriro ese ari maviri evhu rakamira uye rinoshanduka, zvichiratidza nguva yakachengetwa yekuboorwa kwevhu.
MuOman, chinangwa chakawana kurasikirwa kwakaganhurirwa kwemabhareni anosvika 125 paawa (bbl/hr) uye kurasikirwa kwakaganhurirwa kwe280 bbl/hr (550 gallons paminiti, gpm) kusvika "kurasikirwa kwakazara." Kuumbwa kwacho kwaive nekuoma kwevhugular. Chinangwa chemutengi chaive chekupomba mhinduro inoshanda yeLCM yekugadzirisa kurasikirwa nekukurumidza mushure mekusvika pakadzika kwese (TD) uye kuita mabasa ekucheka matanda pasina kudiwa kwemapulagi esimende, nokudaro kuchengetedza nguva yekuboorera. Kurapa kweHFLS neRFLCM kwakasanganiswa mumvura, kwakapombwa kuburikidza nechikamu chinotenderera, uye kwakaiswa muitiro wekudzvanya unotenderera nekuwedzera kumanikidzwa zvishoma nezvishoma. Mushure mekudzvanywa, mwero wekurasikirwa kwakaganhurirwa uye kwakaganhurirwa wakaderedzwa kusvika zero, zvichibvumira mabasa kuenderera mberi zvakachengeteka.
MuUAE, chinangwa chakashandisa mvura yekuboorera isiri yemvura. Mumamiriro ezvinhu asingachinji, kurasikirwa kwaibva pa85 kusvika 200 bbl/hr, nepo mumamiriro ezvinhu anochinja (kuyerera kwe990–1250 gpm), chiyero chekurasikirwa chaive 150 bbl/hr. Kuumbwa kwacho kwairatidzwa nekupwanyika kwakagadzirwa zvechisikigo. Zvikamu zveHFLS neRFLCM zvakasanganiswa muoiri yebase, zvikapombwa nepasi rinotenderera, uye zvakaiswa mukuita kwekudzvanywa kunotenderera nekumanikidzwa kunowedzera zvishoma nezvishoma. Mushure mekudzvanywa, chiyero chekurasikirwa chisingachinji chakaderedzwa kusvika pa2–15 bbl/hr, uye chiyero chekurasikirwa chinochinja chakaderedzwa kusvika pa25 bbl/hr (kudonha kusvika pa5 bbl/hr panguva yekuboorera), zvichibvumira mabasa kuti atangezve.
Mumiedzo yekuongorora tekinoroji, kugona kuvhara maburi/maburi akapfumbuka murabhoritari ane maburi anosvika 40,000 microns kwakapa chivimbo chekuti musanganiswa weLCM unogona kubata saizi dzisina kujeka dzekuputsika/maburi. Kushandiswa kwakabudirira mumunda kwakagadzirisa kurasikirwa kukuru kusvika kuhuwandu, zvichisimbisa nzira yeHFLS/RFLCM dual. Chinhu chakakosha zvikuru chetekinoroji yeLCM yakagadziriswa kudzikiswa kwemitengo yekuvaka matsime nekuderedza nguva yekuboora inobatanidzwa nekugadzirisa kurasikirwa kukuru kusvika kuhuwandu.
Tichienzanisa sisitimu yekuyerera kweropa yataurwa pamusoro apa, kambani yedu yakagadzira zvigadzirwa zviviri yakazvimirira: iyo High Fluid Loss Squeeze (HFLS) agent FC-FLS uye iyo Reticulated Foam LCM (RFLCM) agent FC-LCM, zvese izvi zvinobudirira zvakaenzana neHalliburton's Foam Wedge Lost Circulation System.
