Chii chinonzi Thru-tubing Inflatable Bridge Plug tekinoroji?

Nhanganyaya yeTekinoroji: Panguva yekugadzira, matsime eoiri negasi anofanirwa kuita plugging yechikamu kana mamwe mabasa ekuwedzera nekuda kwekuwedzera kwemafuta asina kuchena emvura. Nzira dzakapfuura ndedzekuisa chidhirowa kana chidhinha chekushanda, kuuraya tsime, kuburitsa tubing yekugadzira, nekuisa plug yebhiriji kana jekiseni Cement inosimbisa aquifer, uye ipapo pombi yemafuta yekugadzira inogadzirwa. Iyi tekinoroji yechinyakare haingove nemitengo yakakwira yekugadzira, asi zvakare inosvibisa dhizaini inogadzira mafuta zvakare, inokanganisa kugadzirwa. Panguva imwecheteyo, zvakaoma kudzora kudzika kwebhiriji plug. Baker Oil Tool nguva pfupi yadarika yakakurudzira tekinoroji nyowani yekuvharisa mafuta inonzi "cable-set oil pipe expansion bridge plug technology." Iyi tekinoroji ine yakaderera maitiro zvinodiwa, mutengo wakaderera, mhedzisiro yakanaka uye plug yebhiriji inogona kudzokororwa. Mhedzisiro yehupfumi inonyanya kuoneka kana uchishanda pagungwa.

Mamiriro ehunyanzvi: Hapana rig yekuchera kana workover rig, pombi yemafuta kana coiled tubing midziyo inodiwa pakuseta plug yebhiriji. Kusauraya tsime kunodzivirira zvakare kusvibiswa kweiyo mafuta layer. Inochengetedza inopfuura hafu yenguva zvichienzaniswa nemidziyo yechinyakare. Yakashongedzerwa nemagnetic positioner kuti inyatso kudzora kudzika kwekupinda. Kugarisana kwakanaka uye kunogona kushandiswa nechero cable system. Inogona kudzorwa kure, iyo inonyanya kubatsira munzvimbo dzakawanda senge mapuratifomu ekuchera ayo asina kukodzera kuvharirwa tubing mashandiro. Inogona kupfuudzwa kuburikidza neakasiyana mataurirwo etubing, casing, drill pombi, kana kuiswa mairi (ona tafura pazasi). Inogona kumira musiyano wekumanikidza we41.3 MPa mumativi ese. Mushure mekunge plug yebhiriji yaiswa, simende inogona kubaiwa papuragi yebhiriji kuti ishanduke kuita plug yebhiriji zvachose. Kukurira misiyano yakakura yekumanikidza. Coiled tubing kana waya tambo inogona kushandiswa kupora uye kuburitsa kunze.

Kushanda musimboti: Tanga wabatanidza maturusi muhurongwa hunoratidzwa pazasi wobva wadzika mutsime. Iyo magineti locator inobvumira plug yebhiriji kudzikiswa kune yakavimbika kudzika. Maitiro ekushanda ehurongwa ane matanho mashanu: downhole, kuwedzera, kudzvinyirira, kununura uye kupora. Kana zvaonekwa kuti nzvimbo yeplug yebhiriji ndeyechokwadi, simba rinopihwa pombi yekuwedzera iri pasi kuti ishande. Pombi yekuwedzera inosefa mvura inouraya zvakanaka kuburikidza nesefa yobva yaisveta mupombi kuti imanikidzire, yoishandura kuita mvura yekuwedzera nekuipomba mubhiriji plug rabha dhiramu. Iyo bhiriji plug yekumisikidza kushanda inodzorwa uye inoteverwa kuburikidza nekuyerera kwazvino pane yepasi monitor. Paunenge uchitanga kupomba mvura mubhurogi plug, kukosha kwekutanga ikozvino kunoratidza kuti chishandiso chekumisikidza chatanga kushanda. Kana kukosha kwazvino kuchiwedzera nekukurumidza, zvinoratidza kuti plug yebhiriji yakawedzera uye yakatanga kumanikidza. Apo kukosha kwezvino kwekutarisa kwevhu kunoderera kamwe kamwe, zvinoratidza kuti hurongwa hwekugadzirisa hwakasunungurwa. Maturusi ekuseta uye tambo zvinosiiwa zvakasununguka uye zvinogona kudzokororwa. Iyo set bridge plug inogona kumira nekukasira mutsauko wepamusoro pasina kudiwa kwekuwedzera madota kana simende kudirwa. Iyo set bridge plug inogona kudzoserwa nekupinda mutsime netambo michina panguva imwe. Kudzvanyirira kusiyanisa kuenzanisa, kuzorora uye kudzoreredza zvese zvinogona kupedzwa murwendo rumwe.
