Pangeboran Stabiliser Downhole Equipment of BHA
A stabilizer pangeboran mangrupakeun sapotong parabot downhole dipaké dina assembly liang handap (BHA) tina senar bor. Ieu mechanically stabilizes BHA dina borehole dina urutan ulah sidetracking dihaja, geter, sarta mastikeun kualitas liang keur dibor.
Ieu diwangun ku awak cylindrical kerung jeung wilah stabilizing, duanana dijieunna tina baja-kakuatan luhur. Bilah tiasa lempeng atanapi spiral, sareng hardfaced pikeun tahan ngagem.
Sababaraha jinis penstabil pangeboran dianggo di lapangan minyak ayeuna. Bari stabilisator integral (pinuh machined kaluar tina sapotong tunggal baja) condong jadi norma, tipe séjén bisa dipaké, kayaning:
penstabil leungeun baju replaceable, dimana wilah anu lokasina dina leungeun baju a, nu lajeng ngaco dina awak. Jinis ieu tiasa ekonomis nalika teu aya fasilitas perbaikan anu caket sareng sumur anu dibor sareng angkutan udara kedah dianggo.
Penstabil bilah dilas, dimana bilah dilas kana awak. Jinis ieu biasana henteu disarankeun dina sumur minyak kusabab résiko kaleungitan bilah, tapi biasa dianggo nalika ngabor sumur cai atanapi di lapangan minyak murah.
Biasana 2 nepi ka 3 penstabil dipasang kana BHA, kaasup hiji ngan luhureun bor bit (deukeut-bit penstabil) jeung hiji atawa dua diantara kerah bor (string stabilizers).
