Iithegi zeMveliso

Umbhobho wokubhomba ojikelezayo

Umngxuma wokugrumba wenziwe ngokuqhekeza i-rock stratum yintshukumo ejikelezayo yesixhobo sokomba.Iindidi eziphambili zoomatshini bokwemba ngoomatshini abakhulu kunye nabancinci bokwemba imbiza, oomatshini bokomba betafile obujikelezayo obujikelezayo obujikelezayo, oomatshini bokomba bentloko behydraulic bamandla, kunye noomatshini bokwemba be-rotary vibration.Umatshini wokugaya ojikelezayo olula unesixhobo sokubhoboza kuphela, kwaye umatshini wokugrumba kakuhle onesakhiwo esigqibeleleyo uqukethe isixhobo sokugaya kunye nokujikeleza isixhobo sokuhlamba kakuhle.Izixhobo zokugaya zetafile ejikelezayo umatshini wokugaya iquka umbhobho wokubhobhoza kunye ne-drill bit.Ubukhulu bombhobho wokubhobhoza osetyenziswa ngokuqhelekileyo yi-60, 73, 89 kunye ne-114 mm.I-drill bit yahlulwe yangamacandelo amabini: isuntswana eligcweleyo lokomba kunye ne-ring drill bit.

Ii-cone drills ezinkulu nezincinci

Isixhobo sokugaya i-conical sisetyenziselwa ukusika okujikelezayo komgangatho womhlaba.Ngokobukhulu bezixhobo zokomba, zibizwa ngokuba yikowuni yembiza enkulu kunye nekowuni yembiza encinci, enokuthi iqhutywe ngabasebenzi okanye amandla.Iimvuthuluka zomhlaba ezisikiweyo ziwela embizeni kwaye ziphakanyiswe emhlabeni ukuze zikhutshwe.Ulwakhiwo lulula kwaye ukusebenza kakuhle kuphantsi.Ingasetyenziswa kuphela kumaleko womhlaba jikelele okanye kwisitrato esinengqalutye yesanti ubukhulu obungaphantsi kwe-10 cm kunye nesiqulatho esingaphantsi kwama-50%.Ububanzi bomngxuma we-cone encinci yi-0.55M, kwaye ubunzulu bokomba yi-80-100m;Ubukhulu bomngxuma yi-1.1m kwaye ubunzulu bokomba yi-30-40m.

Umbhobho ojikelezayo wokuhlamba kakuhle ngodaka olujikelezayo

Yenziwe yinqaba, iwintshi, itafile ejikelezayo, isixhobo sokomba, impompo yodaka, impompo kunye nemoto.Ngexesha lokusebenza, itafile ejikelezayo iqhutywa ngumatshini wamandla ngesixhobo sothumelo, kwaye i-drill bit iqhutywa ngumbhobho wokubhobhoza osebenzayo ukujikeleza ngesantya se-30 ~ 90 rpm ukuqhekeza i-rock stratum.Udaka luyampontshwa kwaye lucinezelwe yimpompo yodaka, emva koko lucinezelwe kumbhobho wokugrumba umngxuma kwitephu engaphezulu kombhobho wokubhobhoza, luqukuqelele ezantsi kwindawo yokubhola, kwaye lukhutshiwe kumbhobho ukuze luphole kwaye luthambise isuntswana lokubhola;Ukusikwa komngxuma ongezantsi kukhutshelwa ngaphandle kwentloko yomthombo ngomjelo we-annular ngaphandle kombhobho wokubhoboza.Emva kokuzinza kwitanki yentlenga, udaka lubuyela emva kwitanki yodaka ukuze luphinde lusetyenziswe.

Reverse circulation udaka ukuhlamba udaka rotary rig yokomba

Indlela yokugaya kunye nesakhiwo ngokusisiseko iyafana nale ingasentla, kodwa indlela yokujikeleza yodaka ichasene.Emva kokuzinza kwitanki yokumisa, udaka luqukuqela lungene emazantsi equla lusuka kwintloko yomthombo, luze udaka oluthwele iingceba zimpompe ngaphandle kwequla ngempompo yentlabathi ngombhobho wokubhoboza umngxuma ongaphakathi wombhobho wokubhoboza uze ubuyele equleni. itanki yokumisa.Le ndlela ibizwa ngokuba yi-pump reverse circulation.Impompo ingasetyenziselwa ukutofa amanzi acinezelekileyo ukusuka ezantsi kwequla ukuya kumngxuma ongaphakathi wombhobho wokugrumba ngombhobho ukuze zenze ukunyuka kwamanzi okuthwele izisikwa, oku kubizwa ngokuba yijet reverse circulation.Umatshini wokugaya unokwenza isantya esiphezulu kakhulu sokunyuka kumbhobho wokubhobhoza, kwaye unamandla amakhulu okukhupha amaqhekeza amatye kunye neengqalutye, ngoko ke isantya sokomba sikhawuleza.Ilungele umaleko womhlaba, umaleko wesanti jikelele kunye nokwakheka okuxekethileyo apho ububanzi bengqalutye buncinane kunobubanzi obungaphakathi bombhobho wokomba.I-diameter yangaphakathi ye-drill pipe esetyenziswayo inkulu, ngokubanzi i-150-200 mm, kwaye ubuninzi buyi-300 mm.Nangona kunjalo, ngenxa yothintelo lokufunxa impompo okanye umthamo wokuhanjiswa koxinzelelo, ubunzulu bokomba ngokuqhelekileyo bungaphantsi kwe-150 yeemitha, kwaye ukusebenza kakuhle kokususa itshiphu kuphezulu xa ubunzulu bequla bungaphantsi kweemitha ezingama-50.

Isixhobo sokomba esijikelezayo sokugungxulwa kakuhle komoya

Isebenzisa icompressor yomoya endaweni yempompo yodaka kunye nomoya ocinezelweyo endaweni yodaka ukuze ihlambe kakuhle kwirotary rig yokomba.Ukujikeleza okubuyela umva ngokuqhelekileyo kusetyenziswa, okukwabizwa ngokuba yi-gas lift reverse circulation.Oko kukuthi, umoya ocinezelweyo uthunyelwa kwigumbi lokuxuba amanzi omoya equleni ngombhobho wokuhambisa umoya ukuze udibanise nokuhamba kwamanzi kumbhobho wokubhobhoza ukuze wenze ukuhamba kwamanzi ane-aerated kunye nomxhuzulane othile ongaphantsi kwe-1. Phantsi komxhuzulane Intshukumo yomqolo wamanzi ojikeleza umbhobho wokugrumba, amanzi afakwe umoya kumbhobho wokugrumba athwala amaqhekeza anyuke aze aphume equleni, aqukuqelele kwitanki yentlenga, kwaye amanzi emva kokwehla kwentlenga abuyela equleni ngomxhuzulane.Xa ubunzulu bequla bungaphezu kweemitha ezingama-50, ukusika umthamo wolu hlobo lwesixhobo sokomba sikhulu kunoko kwesixhobo sokomba ngokufunxa impompo okanye ukujikeleziswa kwejethi umva, ngoko ifanelekile kwimeko yobunzulu bomthombo omkhulu, indawo eyomileyo. ngokunqongophala kwamanzi kunye nomaleko womhlaba onomkhenkce kwindawo ebandayo. (ezinye izixhobo zokomba ezijikelezayo zixhotyiswe ngempompo yodaka kunye necompressor yomoya ngaxeshanye, ngoko ke iindlela ezahlukeneyo zokuhlamba kakuhle zinokukhethwa ngokwemeko.)

I-hydraulic power drill entloko

Uhlobo lwe-rotary drilling rig.Iqhutywa yi-hydraulic motor ngokusebenzisa isinciphisi, kwaye intloko yamandla ihamba inyuka kwaye ihla ecaleni kwenqaba ithatha indawo ye-turntable kunye ne-faucet kwirigi yokubhola ejikelezayo ukuqhuba umbhobho wokubhobhoza kunye nesuntswana lokubhola ukujikeleza nokusika isitrato samatye.Imithombo yamanzi edayamitha emikhulu inokugrunjwa nge-drill bit enkulu enobubanzi obuyi-1m.Ibonakala ngesantya esikhawulezayo sokomba, ukudityaniswa okulula kunye nokuchithwa kwezixhobo zokomba kunye nokuqhutywa kwemibhobho yomthombo, akukho mfuneko yokuphakamisa izixhobo zokomba xa kusandiswa imibhobho yokubhobhoza, kunye nothotho lwamacandelo anjengama-hoists, iibhloko zokuphakamisa, ii-turntables, iitephu kunye noKelly. kuphetshwa.

Phantsi umngxuma vibration umatshini rotary sokomba

Luhlobo lwesixhobo sokomba esijikelezayo esidibanisa ukungcangcazela kunye nentshukumo ejikelezayo ukugrumba isitrato samatye.Isixhobo sokugaya siqulunqwe nge-drill bit, i-vibrator, i-vibration eliminator kunye ne-cylinder yesikhokelo.Amandla achulumancisayo aveliswa yi-vibrator enza ukuba isixhobo sokomba sijingi.I-drill bit igqunywe ngaphandle kweqokobhe le-vibrator ngeringi yokukhuhlana.Ngakolunye uhlangothi, i-vibrate kunye ne-vibrator kwisangqa esithe tye kunye ne-frequency malunga ne-1000 rpm kunye ne-amplitude malunga ne-9 mm;Ngakolunye uhlangothi, yenza intshukumo ejikelezayo ephantsi kwe-3-12 RPM malunga ne-axis ye-vibrator ukuphula ilitye, ngelixa umbhobho wokubhobhoza ungajikelezi, kwaye usebenzisa i-vibration eliminator ukuphepha ukuhambisa ukungcangcazela kwi-drill. umbhobho.Indlela yokujikeleza kwe-air reverse ecinezelweyo isetyenziselwa ukuhlamba iqula, ukwenzela ukuba i-cuttings ikhutshwe equleni ngombhobho kunye ne-drill cavity kwi-vibrator.Olu hlobo lwe-drill lunesakhiwo esilula kunye nokusebenza okuphezulu kokugaya.Ububanzi bomngxuma bumalunga ne-600mm kwaye ubunzulu bokomba bungafikelela
