Moteri y'Ibyatsi ni iki?

ItsindaMoteri yo Kwimura Abantu Bafite Ingufu (PDM), izwi kandi nka"moteri y'ibyondo","ni ikintu gikomeye cyaneigikoresho cyo gucukuraikoreshwa mu bikorwa bya peteroli na gaze. Ihindura ingufu za hydraulic ziva mu mazi acukura (icyondo) mu kuzizunguruka mu buryo bwa mekanike kugira ngo itware igice cy'imashini, bigatuma iba ingenzi mu gucukura mu cyerekezo, mu mariba atambitse, no mu kuyobya inzira.

I. Imiterere n'Ihame ry'Imikorere

1. Ibice by'ingenzi

Valve yo kunyuramo: Ituma amazi atembera neza mu gihe cyo kugwa kugira ngo hirindwe kwiyongera k'umuvuduko.

Igice cya moteri: Igice cy'amashanyarazi cy'ibanze, kigizwe nastator(umuyoboro urimo elastomer) narotor(vis y'icyuma gikoze mu cyuma).

Ihuriro rusange: Ihindura ingendo y’urukiramende idasanzwe mu kuzunguruka kwayo.

Umugozi wo gutwara: Yohereza torque ku gice cyo gucukura, ishyigikiwe n'ibice by'ingufu ku mitwaro ya axial/radial.

2.Ihame ry'imikorere

Amazi yo gucukura afite umuvuduko mwinshi yinjira muri moteri, agatuma rotor izenguruka muri stator mu buryo bw'isi (guzunguruka + kuzenguruka).

Ukuzunguruka kwa rotor kwimurirwa mu gice cy’urukuta n’umugozi ujya mu gice cyo gucukura.

Igipimo cy'umuvuduko w'amazi (Q) ugereranije na RPM (N):

N=qQ×ηv?

Q: Igipimo cy'amazi asohoka (L/s)

q: Kwimuka kuri buri revolution (L/rev)

ηv​: Ingufu z'ingano (ubusanzwe 80–90%)

II. Gushyira mu byiciro PDM

1. Binyuze mu gishushanyo mbonera

PDM ya Lobe imwe (imiterere ya 1: 2): Umuvuduko mwinshi, imbaraga nke (urugero, ku gucukura umwobo muto).

Multi-Lobe PDM (urugero, imiterere ya 5:6): Umuvuduko muto, imbaraga nyinshi (urugero, ku bice binini cyangwa imiterere ikomeye).

2. Binyuze mu gusaba

PDM isanzwe: Ikoreshwa mu byobo bihagaze cyangwa byoroheje.

Bent Housing PDM: Ifite inguni idahindagurika (urugero, 1°, 1.5°, 2°) yo kugenzura icyerekezo.

Turbine-PDM y'ubwoko bwa Hybrid: Ihuza RPM (turbine) iri hejuru hamwe na torque iri hejuru (PDM).

III. Ibipimo by'ingenzi by'imikorere

IV. Guhitamo no Gukoresha

1. Ibipimo ngenderwaho byo guhitamo

Ubukomere mu miterere: Imiterere ikomeye isaba PDM nyinshi kugira ngo torque ibe nyinshi.

Inzira y'Iriba: Amariba y'icyerekezo akeneye PDM zigoramye.

Amazi yo gucukura: Ibyondo bishingiye kuri peteroli bisaba elastomer zirwanya peteroli (urugero: HNBR); ibidukikije bya H₂S bikenera ibikoresho bisukura.

2. Porogaramu zisanzwe

Gucukura mu buryo butambitse: Ikoreshwa na sisitemu za MWD/LWD kugira ngo iyobore neza.

Gukurikirana no gukora imyitozo ngororamubiri: Itanga uburyo bwo kuzenguruka nyuma yo gusohoka mu gisenge.

Amariba maremare/yimbitse cyane: Ikenera stators zishyuha cyane n'ibikoresho bikomeye.

V. Gutsindwa no Kubungabunga Ibisanzwe

VI. Ingendo z'ejo hazaza

1.PDM zigezweho: Ibikoresho by’ikoranabuhanga bikoresha uburyo bwo kugenzura torque/ubushyuhe/gutigita mu gihe nyacyo.

2.Ibikoresho bigezweho: Rotor zikozwe muri nanocoated, elastomer 200°C++.

3.Sisitemu zivanze: PDM + turbine ihuza imiterere igoye.

Landrill ishobora gutanga ubwoko bwa moteri z'ibyondo (PDMS) zifite ubuziranenge bwiza. Niba ubikoraUbashishikajwe nabo, nyamuneka utubwire. Dushobora kuboherereza ibisobanuro birambuye.
