Ukwelashwa okungaphezulu kwe-downhole motor- ikhambi eliyimpumelelo lokugqwala ku-brine egcwele

1. Ixazulule ngempumelelo inkinga yokugqwala ku-brine egcwele.

Ukuqhathanisa indlela yokucubungula:

a. I-Chromium plating iyindlela esetshenziswa kakhulu njengamanje. Amaphesenti angu-90 amakhasimende e-petroleum asekhaya asebenzisa le ndlela, enokuphila okufushane kwesevisi kanye nenani eliphansi. Inkinga enkulu ye-electroplating ukungcoliswa kwemvelo, futhi i-electroplating ayikwazi ukusebenza ku-brine egcwele.

b. Ukufafaza i-WC, amakhasimende ngokuyisisekelo adinga i-WC enamathela kumathuluzi okumba, ngaphezu kokumelana okuqinile kokugqoka, futhi amelana ne-hydrogen sulfide, amanzi anosawoti nokunye ukugqwala. Ububi yizindleko eziphezulu, futhi inzuzo yimpilo ende yesevisi. Ithuluzi lokumba selisetshenziswe isikhathi esingaphezu kwamahora angu-600 futhi lisaphelele, futhi lingasetshenziswa ngokujwayelekile ku-saturated brine.

2. Ubuchwepheshe Bokumboza Xazulula Inkinga Yokugqwala Kwamanzi Anosawoti Agcwele

a. Ubuchwepheshe bokumboza (bethula kuphela isisombululo esiyimpumelelo senkinga yokugqwala emanzini anosawoti agcwele)

Amaphampu anodaka anezindawo ezigqamile ze-helical ezibizwa ngokuthi “ama-lobe” anama-lobe angu-4, 5 noma angu-7 phezulu okuthiwa ama-crests (noma ama-crests). Ama-crests akha "ububanzi obuyinhloko". Usayizi oyinhloko uyahlukahluka kusuka ku-4.0 kuya ku-6.5 amayintshi, okuba ububanzi bemoto.

Iphuzu eliphansi kunazo zonke libizwa ngokuthi umkhombe (noma umkhombe), futhi umkhombe wakha “ubukhulu obuncane”. Ibanga elijwayelekile ukusuka ku-lobe ukuya emkhombeni licishe libe ngu-¼-intshi (6.35mm). Kunezidingo eziqinile kakhulu ze "wave top" maphakathi nenjini kanye "nokweqa" phakathi kwamaphethelo amabili. Njengendinganiso, inani "eliphelile" kufanele libe ngaphansi kuka-0.010" (0.254 mm). Noma yini enye futhi ipayipi lerabha lephampu lizocekelwa phansi ngokushesha lapho injini ijikeleza phakathi nokusebenza.

ukulungiswa kwendawo

a. Ukuze kufakwe isifutho, ukuqhunyiswa kwegrit akudingekile. Indawo engaphezulu idinga ukuhlanzwa ngamathuluzi ezandla kuphela uma kunesidingo noma kudingekile ukwehlisa amafutha. Ukufafaza kusengasetshenziswa njengesipele, lapho kudingekile ukuhlanza ngokushesha indawo engaphezulu noma ukulungisa ingxenye yesigqoko esifuthiwe.
