Natural Gas Well Foam Drainage Agent

Nrog rau kev siv cov khoom siv hluav taws xob, kev tsim cov siab txo qis, thiab cov roj rov qab tau txo qis, ua rau muaj kev cuam tshuam zoo, ua rau muaj kev kub ntxhov ruaj khov ntawm cov roj Wells kom txog rau thaum cov roj av crushed kom tuag. Txij li xyoo 2017, lub koom haum Shanghai tau tsim cov roj- cov tshuaj tiv thaiv ua npuas dej thiab qhov kub thiab txias- cov kua qaub resistant- cov dej ua npuas dej rau cov roj reservoirs uas muaj cov condensate thiab ultra- qhov tob tob uas muaj hydrogen sulfide thiab ua tiav cov ntawv thov kev lag luam.

Roj-cov khoom ua npuas dej resistant, cov yam ntxwv tseem ceeb ntawm cov khoom yog raws li nram no:

◆ Tsawg roj-kua qhov nro, ceev foaming ceev: y=27.5mn/m;

◆ Nrog kev sib txuam siab, cov condensate tuaj yeem nkag mus rau hauv cov kua nplaum ua npuas dej (kev nkag coefficient E＞O) tab sis nws tsis haum rau kev sib kis ntawm cov yeeb yaj kiab ua kua (kwv yees coefficient S Tsawg dua lossis sib npaug rau 0);

◆ Tsis muaj peev xwm emulsifying rau cov roj condensate;

◆ Rau cov condensate uas muaj 60%, qhov ua npuas dej ntws ntau dua lossis sib npaug li 60%.

Kub-resistant, acid-resistant ua npuas dej tus neeg sawv cev muaj ob hom kua thiab khoom rods, lub ntsiab nta ntawm nws cov khoom yog raws li nram no:

◆ Kub tiv taus 140 degree;

◆ pH 2 - 11;

◆ Foam drainage rate >80%.

Thaum lub Tsib Hlis 2019, cov roj- tiv thaiv ua npuas dej tau txhaj rau hauv Jiangsha Gas Field ntawm Sinopec Southwest Oil thiab Gas Tuam Txhab, cov ntsiab lus condensate yog 50-60 vol%, cov roj tes lub tes tsho siab sib txawv tau txo los ntawm 1.0MPa rau 0.28MPa tom qab siv, thiab cov kua accylinder 0.6% ntau lawm hauv lub hli. Kev poob qis yog txo los ntawm 13.2% mus rau 2.5%.

Nyob rau lub Peb Hlis 2020, qhov kub thiab kua qaub- tiv thaiv npuas dej tau txhaj rau hauv qhov dej ultra- qhov tob (6100 meters) nrog cov ntsiab lus hydrogen sulfide siab hauv Puguang Gas Field ntawm Sinopec, thiab cov pa roj thiab cov kua ua kua dej nyab los ntawm 0 txog 190 square metres / hnub.

Thaum lub Yim Hli 2020, lub tshav kub- tiv taus thiab kua qaub- tiv thaiv npuas dej tau raug txhaj rau hauv ultra- qhov tob (7,200 meters) uas muaj hydrogen sulfide hauv Sinopec Yuanba Gas Field, thiab cov kua ntau lawm tau nce ua ntej dej nyab 3.4 npaug, cov roj ntau lawm tau nce ntawm 9x3/10'm'm.
