Drilling Riser

Mumabasa ekuchera kunze kwemahombekombe, thekuchera riserinoshanda seyakakosha tubular link inojoinha iyosubsea wellhead uye blowout kudzivirira (BOP)kupamusoro pekuchera chikuva.
Pane kuti ishande sechigarire kikasi -sepombi kondakita{1}}rinosimudza rinoshanda sekwenguva pfupi, -yakakwirira mukotoinoshandiswa chete panguva yekuchera.

Chinangwa chayo chikuru ndechekugadzira anzira inodzorwakuitira kutenderera kwemvura yekuchera, zvicherwa, uye-kudzora kumanikidzana pakati pepasi pegungwa nepasi.
Izvi zvakavharwa-loop circulation zvinoita kuti pressure balance, fluid recovery, uye kuenderera mberi nekutarisa mutsime panguva yese yekuchera.

Inmvura yakadzika uye-yakadzika yakadzikamashandiro, uko kusingagoneke kupinda mumisoro yemvura yepasi pegungwa, chinosimudzwa chinova chikamu chakakosha chegadziriro yekudzora matsime.
Inofanirwa kushingirira kusimba kwemugungwa, kusanganisira vertical heave, current drift, uye hydrostatic loads{{0}kazhinji pakadzika kupfuura2,000 mamita.

Mazuva ano riser maassemblies anosanganisiratension joints, buoyancy modules, uye kuisa chisimbiso zvinhuiyo pamwe chete inovimbisa kugadzikana kwemuchina, kudzvanywa, uye kuchengetedzwa kwekushanda pasi pekuchinja kunoramba kuchichinja mamiriro ekunze.

A kuchera riserinoshanda seyekutanga mechanical uye hydraulic link pakati pepamusoro rig uye subsea tsime system, ichiva nechokwadi chekuenderera mberi kwekutonga uye kutaurirana panguva yekuchera kwemahombekombe.
Magadzirirwo ayo anobatanidza mabasa akasiyana-siyana anoshanda pamwechete kuchengetedza kugadzikana kwekushanda uye kuchengetedzeka munzvimbo dzakavhurika-mugungwa.

• Hydraulic Return Path:Mukwirimu unoisa nzvimbo yakavharwa kuti madhaka adzoke, zvichiita kuti kutakurwa kwakanaka kwezvichekwa uye kuchengetedza pasi{0}}paburi chairo.
• Well Pressure Regulation:Yakabatanidzwa inodzipa uye mitsara yekuuraya inobvumira yakachengetedzwa kudzvanywa mashandiro, ichipa yechipiri kuchengetedza envelopu yekutendeseka zvakanaka.
• Motion Accommodation:Kuburikidza nemusanganiswa wemajoini anochinjika, tension mhete, uye buoyancy zvinhu, riser inoramba yakabatana kunyangwe rig heave uye lateral displacement.
• Structural Backbone:Iyo inotsigira mitsara yekubatsira yekudzora uye inopa yakaomesesa asi inochinjika nzira yemakanika uye fluid masisitimu anobatanidza rig uye BOP stack.
• Operational Reusability:Kuvakwa kwemodular kunobvumira chikwiriso chega chega kuti chivharwe, chiongororwe, uye-chibvumidzwezve, kuve nechokwadi chekushanda-kwenguva yakareba yemitengo pamishandirapamwe yakawanda yekuchera.

Imwe neimwe yeaya magadzirirwo emhando inoratidza basa rekusimuka sedynamic structure system, haina kugadzirwa chete kuti ive nesimba asi kuchengetedza mutinhimira wemuchina wekuchera mvura yakadzika.

AtOctal Pipe, madrilling risers anogadzirwa uye anoedzwa kuita pasimamiriro akanyanya ekumahombekombe.
