Lub luag haujlwm ntawm kev muaj kev muaj zog polyacrylamide hauv cov roj tawm

Cov khoom ntawm muaj polyacrylamide rau thickening, flocculation thiab rawv cov kev cai ntawm cov kua ua kom nws lub luag haujlwm tseem ceeb hauv kev tsim cov roj av. Nws yog dav siv hauv kev drilling, aciding dej, ua tiav huv, ua tiav, coj kev txiav tawm, coj kev sib tw thiab cov roj kev hloov pauv.

Feem ntau, kev siv polyacrylamide yog txhawm rau txhim kho tus nqi rov qab. Tshwj xeeb, ntau cov roj av tau nkag mus rau hauv cov txheej txheem thib ob thiab qib tertiary, qhov tob ntawm lub qhov tob, thiab qee qhov tob ntawm lub pas dej uas muaj txog 7000m. Lub heterogeneity ntawm qhov tsim thiab sab nrauv cov liaj teb tau muab tso rau tom ntej ntau txoj hlua rau cov roj rov ua haujlwm.

Ntawm lawv, cov roj av ntau lawm thiab cov khoom siv hluav taws xob tsis kam,

Muaj polyacrylamide yog siv los ntawm cov kua dej tsis sib xws thiab ua kom cov kua dej ntxiv:

Ib nrab hydrolyzed polyacrylamide (Hpam), uas yog muab tau los ntawm hydrolysis ntawm polyacrylamide, feem ntau siv los ua cov kua hluav taws xob. Nws lub luag haujlwm yog txhawm rau tswj cov rheology ntawm drilling kua, uas tuaj yeem txo cov roj thiab roj ntau dua li cov roj sib tsoo, thiab txog 45% siab dua cov mechanical Drilling tus nqi.

Ib qho ntxiv, nws tuaj yeem txo qis cov nyo druck drilling xwm txheej, txo cov khoom siv hnav, thiab tiv thaiv kev poob thiab tsaus muag. Kev ntsuas thev naus laus zis yog ib qho tseem ceeb tshaj plaws rau kev txhim kho cov txaj kom huv hauv cov roj av. Polyacrylamide fracturing kua yog siv dav vim yog kev sib txhuam siab, zoo me me txhuam, dav siv, kev npaj dav dav thiab tus nqi qis.

Nyob rau hauv qhov khaus thiab acidizing kev kho mob, polyacrylamide tau npaj rau hauv cov tshuaj a a aantration ntawm 0.01% thiab muab tso rau hauv cov av nyob rau qhov kev tsim. Kev muaj kev muaj polyacrylamide daws muaj cov nuj nqi ntawm thickening thiab nqa xuab zeb thiab txo cov kua dej ploj. Tsis tas li ntawd, Polyacrylamide muaj cov nyhuv ntawm kev txo qis tsis kam, yog li kom lub siab hloov kev puas tuaj yeem txo.
