Intshayelelo yeHardbanding

I-Hardbanding yintsimbi enganyangekiyo yokwaleka I-Hardbanding yinkqubo yokubeka phezu kwentsimbi eqinileyo] kwindawo ethambileyo yentsimbi. Ifakwe ngegesi yentsimbi ye-arc welding kumphezulu wangaphandle wokudityaniswa kwesixhobo sombhobho wokomba ukwandisa izixhobo zombhobho wokomba, iikhola, kunye nobomi benkonzo yombhobho wokomba wobunzima kunye nokunciphisa ukuguga komtya wokugrumba onxulunyaniswa nezenzo zokomba.

I-Hardbanding isetyenziswa apho ukujikeleza kunye ne-axial friction ehambelana nokugrumba kunye nokukhubeka kudala ukunxitywa kwe-abrasive ngokugqithiseleyo phakathi kwentambo yokubhobhoza kunye ne-casing okanye phakathi kwentambo yokubhola kunye nelitye. Ukwaleka kwe-Hard alloy kufakwe kwiindawo zoqhagamshelwano olukhulu. Ngokuqhelekileyo, i-hardbanding isetyenziswe kwi-joint yesixhobo njengoko iyona ndawo ibanzi yentambo ye-drill kwaye iya kuqhagamshelana ne-casing rhoqo.

Ekuqaleni, amasuntswana e-tungsten-carbide athotywa kwi-matrix yentsimbi ethambileyo, ehlala esemgangathweni weshishini iminyaka emininzi. Nangona kunjalo, abanini bemithombo bakhawuleza baqonda ukuba ngelixa isixhobo esidityanisiweyo sikhuselwe kakuhle, amasuntswana e-tungsten-carbide ayehlala esebenza njengesixhobo sokusika ngokuchasene ne-casing, ebangela amaxabiso agqithisileyo okunxiba kunye nokusilela kwecasing kwamaxesha athile. Ukujongana nesidingo esibalulekileyo semveliso ye-casing-friendly hardbanding enokukhusela ngokufanelekileyo izixhobo zokudityaniswa kunye nezinye izixhobo ze-downhole.

Iindidi ze-hardbanding:

1. I-hardbanding ephakanyisiweyo (IQINISELA)

2. Flush hardbanding (FLUSH)

3. I-Hardbanding kwi-central upset ye-Drill Collar kunye ne-Heavy Weight Drill Pipe

Imisebenzi yeHardbanding:

1. Ikhusela isixhobo semibhobho yokomba ekuqhawukeni nokuguga kwaye yandisa ubomi benkonzo ye-DP.

2. Ikhusela izixhobo zokusebenza ekuqhekekeni kwe-thermal.

3. Yehlisa ukunxiba kwecasing.

4. Yehlisa ilahleko yokugrumba.

5. I-Hardbanding ivumela ukusetyenziswa kwezixhobo ezidibeneyo ze-OD ezidityanisiweyo.

Usetyenziso lweHardbanding:

1. I-Hardbanding iyasebenza ekuqhubeni imibhobho yazo zonke iisayizi kunye namabakala.

2. I-Hardbanding ingafakwa kwi-new and u    sed tubular.

3. I-Hardbanding ingasetyenziswa kwii-drill pipe tool joints ezenziwe nge-GOST R 54383-2011 kunye ne-GOST R 50278-92 okanye ngokweenkcukacha zobugcisa bemibhobho yesizwe, kunye nezixhobo ze-drill pipe ezenziwe nge-API Spec 5DP.

4. I-Hardbanding ingasetyenziswa kwimibhobho yokugaya kunye neentlobo ezahlukeneyo zezixhobo zesixhobo, kubandakanywa izixhobo eziphindwe kabini zamagxa.

5. I-Hardbanding ingafakwa kwimibhobho yobhola ekwaziyo ukumelana nokubanda kunye ne-DP yenkonzo emuncu.

I-Hardbanding ingafakwa kwi-tubular yezi ntlobo zilandelayo kunye nobukhulu:

1. Umzimba wombhobho we-OD 60 ukuya kwi-168 mm, ubude ukuya kwi-12 m, i-OD yezixhobo ezidityanisiweyo zokudityaniswa ngamaxwebhu e-DP.

2. I-Hardbanding isetyenziselwa ukuphazamiseka kwe-HWDP, kwiindawo ezidibeneyo zesixhobo ze-HWDP, kunye ne-DC yazo zonke iintlobo kunye nobukhulu.

3. I-Hardbanding iphinda isetyenziswe kwi-central upset ye-HWDP kunye ne-DC.

4. I-Hardbanding ingasetyenziswa kwiintsimbi zesixhobo ngaphambi kokuba zifakwe kwi-drill pipe.

Ugcino oluveliswa ngokusetyenziswa kombhobho wokubhola nge-hardbanding:

1. Ubomi benkonzo yombhobho we-Drill bandiswa ukuya kuma-3 amaxesha.

2. Ukugqoka okuhlangeneyo kwesixhobo kuncitshiswa nge-6-15 % kuxhomekeke kuhlobo lwe-hardbanding esetyenzisiweyo.

3. Ukunxiba eludongeni lwe-Casing kuncitshiswe nge-14-20 % xa kuthelekiswa nokunxiba okubangelwa zizixhobo ezingenanto.

4. Yehlisa ilahleko yokukhuhlana kwamaqula.

5. I-torque ye-rotary efunekayo iyancitshiswa, ngaloo ndlela inciphisa ukusetyenziswa kwamandla.

6. Ukuphucula ukusebenza kokomba.

7. Linciphisa ixesha lokomba.

8. Ukunciphisa ukuphindaphinda komtya we-drill kunye nokungaphumeleli kwentambo ye-casing kwimisebenzi yokugaya.
