Lisosa le Litharollo tsa Tahlehelo ea Phetiso ea WOB ho Chekeng

1. Khopolo-taba, Liketsahalo le Likotsi tsa Tahlehelo ea Phetiso ea WOB

Khopolo-taba:Nakong ea ho cheka, khohlano e feteletseng pakeng tsakhoele ea ho phunyale lebota la wellbor le thibela boima ba bit (WOB) ho fetisetsoa ho drill bit—ho e-na le hoo, WOB eohle e jeoa ke drill strip. Sena se bonahala e le sekgahla sa ho kenella ho sa tsotellehe WOB e eketsehileng, khatello ea mokokotlo ha e eo, le torque e tlase. Tharollo e kenyelletsa ho fokotsa lebelo la ho potoloha le ho eketsa butle-butle WOB (ha e ntse e netefatsa hore torque e latela matla a khatello a thapo ea drill) ho fihlela torque e phahama ka tšohanyetso 'me khatello ea mokokotlo ho WOB e hlaha. Kamora ho phunya quilt ka 'ngoe, ho phunya quilt khafetsa le ho phunya quilt hoa hlokahala pele ho hokela quilt kapa stand e latelang.

Liketsahalo le Likotsi:Bothata bona bo hlaha haholo-holo nakong ea ho cheka ka tsela e potolohang ka morao lilibeng tse otlolohileng, ho sila lifensetere le ho khelosa tsela e lebisang lehlakoreng, le ho cheka ka tsela e otlolohileng ka tsela e lebisang lehlakoreng. E sitisa kaho e tloaelehileng ea tsela 'me e ka lebisa ho khomareleng ha phaephe haeba mesebetsi e sa etsoa hantle.

2.Tlhahlobo ea Lisosa

Tsela e Fosahetseng ea ho Sireletsa Metsi:Ho kheloha tseleng ea ho potoloha ha metsi (ho bakoang ke maemo a ho thehoa kapa liphoso tsa kaho) hangata ho hloka liphetoho tsa potoloho ea mali morao. Sekhahla se phahameng sa kaho (se atileng haholo lilibeng tse mahareng/tse khutšoane tse rapameng ho feta tse bolelele ba limithara tse telele) le litsela tse sa tloaelehang, hammoho le ho tiea ha khoele ea ho phunya, li etsa hore khoele ea ho phunya e phomole leboteng la metsi ha khatello e sebelisoa—e leng se bakang tahlehelo ea phetisetso ea WOB. Matla a eketsehileng a ho hula nakong ea ho khoptjoa ka mor'a ts'ebeliso ea khatello a tšoana le maemo a tloaelehileng 'me hangata ha a fete khatello e theohelang tlaase.

Sekoti se Silafetseng (Sebopeho sa Bethe ea Cuttings):Ho tlosa makumane ho thata didibeng tse shebaneng le tsela le didibeng tse otlolohileng tse nang le kheloho ea seliba ea likhato tse 45-90. Libopehong tse thata (mohlala, Shahejie le Kongdian), makumane a bokellana habonolo libetheng. Libethe tsena li eketsa khohlano e thellang pakeng tsa khoele ea ho phunya le lebota la seliba, e leng se lebisang tahlehelong ea phetisetso ea WOB.

Keke ea Seretse e Tetenya le e sa Lokolohang, Koefficient e Phahameng ea ho Fetoha ha Seretse:Ho ba le seretse se tiileng se phahameng ho fella ka dikuku tse teteaneng, tse hlephileng tsa seretse, tse atolosang sebaka sa ho kopana le thapo ya ho tjheka mme di eketsa kotsi ya ho kgomarela. Palo e hodimo ya kgohlano ya seretse e eketsa kganyetso ya ho thella ha thapo ya ho tjheka. Boemo bona bo ka baka ho thiba ka tshohanyetso ha pompo ya ho tjheka ha WOB e eketseha (mohlala, ho ya ho ditone tse 30), ka matla a mang a ho hula a fetang WOB e theohelang tlase.

3. Mehato ea ho Fokotsa Mathata

Taolo ea Tsela ea Wellbore le Ntlafatso ea Likhoele tsa ho Cheka:Kenya tšebetsong ho tjheka ka botlalo ho qoba ho kheloha ha tsela ho hlokang liphetoho tsa potoloho ea mali morao. Nolofatsa sebopeho sa khoele ea ho tjheka (fokotsalikholara tsa ho phunya, eketsa liphaephe tsa ho tjheka tse boima) ho fokotsa ho tiea le ho fokotsa ho kopana le kuku ea seretse, ho thibela tahlehelo ea phetisetso ea WOB le ho khomarela.

E ntlafalitsoe Ho Hloekisa Seretse le ho se Silafatsa:Sebelisa lisebelisoa tsa taolo ea lintho tse tiileng ho hloekisa seretse se ka holim'a metsi. Netefatsa hore ho na le ho falla ho lekaneng (eseng ka tlase ho 3.4 m³/min bakeng sa likarolo tsa liliba tsa φ311, 1.1 m³/min bakeng sa likarolo tsa φ216) 'me u fetole liparamente tsa rheological tsa seretse (karolelano ea YP/PV: 0.42–0.50; viscosity: ≥48 s) ho ntlafatsa bokhoni ba ho jara li-cuttings. Bakeng sa liliba tse rapameng, li phaphametse ho fihlela ho likhato tse 20–30 tsa ho kheloha ho arola libethe tsa li-cuttings.

Ntlafatsa Boleng ba Seretse le Kaka ea Seretse:Kenya lithane tse 3-5 tsa oli e tala (e sa feteng 10%) hammoho le mafura a thehiloeng metsing ho leka-lekanya mafura le boleng ba kuku ea seretse. Kenya asphalt e nang le sulfonate kapa phenolic resin ho ntlafatsa thepa ea kuku ea seretse. Bakeng sa tahlehelo ea phetiso ea WOB ka har'a libopeho tse thata, eketsa 200-300 kg ea graphite e atolositsoeng kapa mafura a khatello e feteletseng ho fokotsa khohlano.
