Mastering Pob Zeb Hla nrog Advanced TCI Tricone Bit.

1. Pob zeb hla txoj kev Drilling

①Drectional drilling txoj kev rau pob zeb hla muaj xws li hauv qab no:

- Kev tsim kho yooj yim

- DITCH WITCH Ob Chav Phab Ntsa Laum Pipe Txoj Kev

- Pneumatic lossis HydraulicDown-the-Hole HammerImpact thiab Rotary Directional Drilling

- Mud Motor Directional Drilling Method

Txoj kev "mud motor directional drilling method" yog tam sim no feem ntau siv txoj kev rau pob zeb directional drilling ob qho tib si hauv tsev thiab txawv teb chaws. Nws yog tsim rau trenchless drilling rigs ntawm 25 tons thiab saum toj no, tshwj xeeb tshaj yog loj trenchless rigs.

Cov av nkos lub cev muaj zog, tseem hu ua lub hau ntswj, feem ntau yog ua ke nrog "tricone laum ntsis"los yog"PDC laum khoomThaum lub sij hawm ib txwm drilling, lub laum pas nrig thiab lub cev muaj zog tig ua ke rau txoj kab ncaj nraim drilling. Rau kev taw qhia drilling, lub tsev khoov ntawm lub cev muaj zog sib haum nrog 12 teev txoj hauj lwm qhia los ntawm qhov chaw nrhiav. tig lub laum me ntsis, ua tiav cov kev taw qhia drilling.

Lub kaum sab xis ntawm av nkos motors rau "kab rov tav drilling khoom” feem ntau yog nyob ntawm 1.5 ° txog 3 °, thiab qhov kev xaiv nyob ntawm qhov curvature ntawm lub raj xa dej tsim.

② Kev sib txuas Configurations rau av nkos Motor Directional Drilling:

- Wireless: Laum pas nrig → Instrument vaj tse → Tsav →Peb Cones xyaum ntsis

- Wired: Laum pas nrig → Non-magnetic laum dab tshos → Instrument tsev → Non-magnetic laum dab tshos → Tsav →Peb Cones xyaum ntsis

 

2. Pob zeb hla Reaming Drilling

Tom qab ua tiav qhov pilot qhov, reaming yog ua raws li txoj kab uas hla.

2.1 Hom Pob Zeb Reamers

① Muaj ob lub ntsiab ntawm pob zeb reamers:

- Tsau Tricone Pob Zeb Reamers: Cov no siv tricone cutter ntu los ntawm oilfield laum khoom ua cov cuab yeej txiav, welded rau reamer lub hauv paus ncej thiab puag phaj.

- Replaceable Roller Cutter Reamers: Cov reamers no siv cov khoom siv hloov pauv tau los ua cov cuab yeej txiav, uas tau nruab rau ntawm cov hlua lossis hauv kev ncua.

② Qhov zoo thiab qhov tsis zoo ntawmTricone Pob Zeb Khoom

Qhov zoo:

- Lub voj voog tsim luv luv.

- Haum rau ntau txoj kab uas hla (tshwj xeeb me me mus rau nruab nrab), xws li 220mm txog 1600mm, thiab yoog mus rau ntau qhov sib txawv geological formations.

- Customizable hniav hom thiab bearing qauv raws li rig thiab tsim tej yam kev mob.

- Ua haujlwm zoo hydraulic pob zeb tawg thiab khib nyiab tshem tawm.

Qhov tsis zoo:

- Rov qab hnav ntawm lub tshuab txiav yog qhov nyuaj rau kev hais nyob rau hauv sandstone formations.

-Qhov opener khoomtuaj yeem hnav tom qab ob peb kho.

- Cov kabmob ntsaws ruaj ruaj ntawm lub cutter interface yog qhov ua rau tsis ua haujlwm, txawm hais tias cov khoom siv los tiv thaiv kev poob qis txo qhov kev pheej hmoo.

2.2 Nta ntawm Hloov Cov Menyuam Cutter Pob Zeb Reamers rau Nruab Nrab-Me Rigs

① Cov kab no:

- Hais txog cov teeb meem hnav rov qab ntawmluag bits.

- Muaj tus nqi sib piv rau cov roj hmab kawTCI tricone khoom, txo cov nuj nqis ua haujlwm.

- Ua kom muaj kev nyab xeeb thiab txhim khu kev lag luam nrog kev hloov cov menyuam cutter yooj yim.

2.3 Nta ntawm Hloov Cov Menyuam Cutter Pob Zeb Reamers rau Loj Rigs

① Cov yam ntxwv tseem ceeb suav nrog:

- Haum rau cov khoom siv hnyav hauv cov pob zeb loj hla hla.

- Nruab nrog reusable lub cev thiabHDD reamer laum khoomtsim los rau kev siv txuas ntxiv.

- Rollers nrog Ø19 carbide hniav thiab customizable profiles (blunt rau tawv pob zeb, conical rau mos pob zeb).

 

3. Drilling Parameters

3.1 Drilling Siab

Drilling siab nyob ntawm tej yam xws li pob zeb hardness, borehole txoj kab uas hla, thiab xyaum me ntsis zog. Siab dhau ntawm cov cuab yeej zoo li covPDC rub me ntsistuaj yeem ua rau cov khoom puas tsuaj.

3.2 Kev sib hloov ceev

Feem ntau khaws cia ntawm 40 RPM lossis qis dua, ua kom muaj kev ua tau zoo rau cov cuab yeej xws licore chim laum khoom.

3.3 Mud Flow

Cov av nkos zoo yog qhov tseem ceeb rau kev ua kom txias thiab tshem tawm cov khib nyiab, tshwj xeeb tshaj yog thaum sivAPI tus qauv tricone khoomnyob rau hauv sandstone formations.

 

4. Av nkos Recovery System

Integrated av purification systems txhim kho drilling efficiency. Lawv txuag cov peev txheej thiab txo qhov cuam tshuam ib puag ncig, ua raws li cov txheej txheem niaj hnub drilling uas feem ntau koom nrogqhov opener khoomthiab cov txheej txheem trenchless.

Qhov zoo:

- Rov qab 80-90% av nkos.

- Txuag 40-50% ntawm bentonite.

- daws cov teeb meem pov tseg av thiab txo qis kev cuam tshuam ecological.
