Zvinokonzera uye Mhinduro dzeKurasikirwa kweWOB Transfer muDrilling

1. Pfungwa, Zviitiko uye Njodzi dzeWOB Transfer Loss

Pfungwa:Panguva yekuboora, kukweshana kwakanyanya pakati petambo yekuboorerauye madziro emugodhi anodzivirira huremu hwechinhu (WOB) kuti husapfuudzirwe kuchinhu chinoboorwa—panzvimbo pezvo, WOB yese inodyiwa netambo yekuboorwa. Izvi zvinoonekwa sekuti hapana mwero wekupinda pasinei nekuwedzera kweWOB, hapana kumanikidzwa kwemusana, uye torque yakaderera. Mhinduro yacho inosanganisira kuderedza kumhanya kwekutenderera uye kuwedzera zvishoma nezvishoma WOB (uku uchiita kuti torque ienderane nesimba rekudzvanya retambo yekuboorwa) kusvika torque yakwira kamwe kamwe uye kumanikidzwa kwemusana paWOB kwaonekwa. Mushure mekuboorwa kwejoini rega rega, kudzokororwa kwejoini uye kudzokororwa kwejoini kunodiwa usati wabatanidza joini rinotevera kana stand.

Zviitiko Nenjodzi:Dambudziko iri rinonyanya kuitika panguva yekuchera gomba reverse-circulation mumigodhi yakamira, kugaya mahwindo nekushandisa nzira yekubvisa gomba, uye kuchera gomba repadivi rakatarisana. Izvi zvinokanganisa kuvaka kwakajairika uye zvinogona kukonzera kuti mapaipi anamire kana mabasa asina kuitwa zvakanaka.

2.Kuongorora Zvinokonzera

Nzira Isina Kunaka Yekubereka Zvine Mutsipa:Kutsauka munzira yekufamba kwemvura (kunokonzerwa nemamiriro ekugadzira kana zvikanganiso zvekuvaka) kunowanzoda kugadziriswa kwekufamba kwemvura kunobva kumashure. Kuwanda kwekuvaka (kwakawanda mumigodhi yepakati nepfupi-yakatwasuka kupfuura yemigodhi yakareba) uye nzira dzisina kurongeka, pamwe chete nekuomarara kwetambo yekuboorera, zvinoita kuti tambo yekuboorera igare pamadziro emugodhi kana paine kumanikidzwa—zvichikonzera kurasikirwa kwekutamiswa kweWOB. Simba rekudhonza rakawedzerwa panguva yekugumburwa mushure mekushandiswa kwekumanikidzwa rakafanana nemazinga akajairwa uye kazhinji haripfuuri kumanikidzwa kwakadzika.

Matanda Akasvibiswa (Kugadzirwa Kwemubhedha Wekucheka):Kubvisa zvidimbu kunonetsa mumatsime akananga uye matsime akatwasuka ane tsime rakatsauka remadhigirii 45–90. Mumaumbirwo akaomarara (semuenzaniso, maumbirwo eShahejie neKongdian), zvidimbu zvinoungana nyore nyore mumibhedha. Mibhedha iyi inowedzera kukweshana kunotsvedza pakati petambo yekuboorera nemadziro etsime, zvichikonzera kurasikirwa kwekutamiswa kweWOB.

Keke reMadhaka Gobvu uye Rakasununguka, Chiyero Chikuru Chekukweshana KweMadhaka:Kuwanda kwehuwandu hwakasimba muvhu kunoita kuti pave nemakeke evhu akakora, asina kusimba, ayo anowedzera nzvimbo yekubata netambo yekuboorera uye anowedzera njodzi yekunamira. Kuwanda kwehuwandu hwevhu kunowedzera kuramba kwetambo yekuboorera. Izvi zvinogona kukonzera kuvharika kwepombi kamwe kamwe kana WOB yawedzerwa (semuenzaniso, kusvika kumatani makumi matatu), nesimba rekudhonza rinopfuura WOB iri pasi.

3. Matanho ekuderedza dambudziko

Kugadzirisa Kudzora Nzira Yekudhonza uye Kuboorera Tambo:Shandisa kuchera kwakanyatsotungamirirwa zvakanaka kudzivirira kutsauka kwenzira kunoda kugadziriswa kwekutenderera kweropa. Rerutsa marongero etambo yekuboorera (deredzamakora ekuboorera, wedzera mapombi ekuboorera anorema) kuderedza kuomarara uye kuderedza kusangana nekeke rematope, kudzivirira kurasikirwa nekunamira kweWOB.

Yakawedzerwa Kuchenesa Madhaka Uye Wellbor:Shandisa michina yekudzora zvinhu zvakasimba kuchenesa matope pamusoro. Iva nechokwadi chekuti pane kusuduruka kwakakwana (kwete pasi pe3.4 m³/min yezvikamu zvetsime zve φ311, 1.1 m³/min yezvikamu zve φ216) uye gadzirisa ma rheological parameters ematope (YP/PV ratio: 0.42–0.50; viscosity: ≥48 s) kuti uvandudze kugona kwekutakura zvidimbu. Kune matsime akatambanuka, wedzera kusvika kumadigirii 20–30 ekutsauka kuti uparadze mibhedha yezvidimbu.

Kuvandudza Runako rweMadhaka uye Hunhu hweKeke reMadhaka:Wedzera matani 3-5 emafuta asina kucheneswa (asingapfuure 10%) pamwe chete nemafuta anozorwa nemvura kuti aenzane nekunyorova uye kunaka kwekeke remud. Isa asphalt kana phenolic resin ine sulfonated kuti uvandudze hunhu hwekeke remud. Kuti ubvise WOB mumafuta akaomarara, wedzera 200-300 kg yemafuta anozorwa egrafiti yakawedzerwa kana mafuta anozorwa zvakanyanya kuti uderedze kukweshana.
