Kugwiritsa ntchito CMC mu Petroleum

Mtundu wa CMC wamafuta amafuta: PAC- HV PAC- LV PAC-L PAC-R PAC-RECMC-HVMtengo wa CMC-LV

1. Ntchito za PAC ndi CMC m'munda wamafuta ndi izi:

1. Matope okhala ndi PAC ndi CMC amatha kupanga khoma lachitsime kukhala keke yopyapyala komanso yolimba yokhala ndi permeability yochepa, kuchepetsa kutaya kwa madzi;

2. Pambuyo powonjezera PAC ndi CMC kumatope, chobowola chikhoza kupeza mphamvu yochepetsetsa yoyambira, kotero kuti matope ndi osavuta kutulutsa mpweya wokulungidwa mmenemo, ndipo panthawi imodzimodziyo, zinyalala zimatayidwa mwamsanga mumatope. dzenje;

3. Kubowola matope, monga kuyimitsidwa kwina ndi kubalalitsidwa, kumakhala ndi nthawi yayitali. Kuwonjezera PAC ndi CMC kumatha kupangitsa kuti ikhale yokhazikika ndikutalikitsa moyo wa alumali.

2. PAC ndi CMC ali ndi zotsatirazi zabwino katundu ntchito oilfield ntchito:

1. Kulowetsedwa kwakukulu, kufanana kwabwino m'malo, kukhuthala kwakukulu, mlingo wochepa, kuwongolera bwino ntchito yamatope;

2. Kukana kwa chinyezi chabwino, kukana mchere ndi kukana kwa alkali, koyenera madzi abwino, madzi a m'nyanja ndi matope odzaza madzi amchere;

3. Ubwino wa keke yamatope opangidwa ndi yabwino komanso yokhazikika, yomwe imatha kukhazikika bwino nthaka yofewa komanso kuteteza khoma lachitsime kuti lisagwe;

4. Ndizoyenera dongosolo lamatope lomwe zolimba zake zimakhala zovuta kuzilamulira ndipo zimakhala ndi kusintha kwakukulu.

3. Kagwiritsidwe ntchito ka CMC ndi PAC pobowola mafuta:

1. Lili ndi mphamvu zowononga madzi, makamaka zochepetsera zowonongeka kwambiri, zomwe zimatha kuwononga madzi pamtunda wochepa kwambiri popanda kukhudza zinthu zina zamatope;

2. Kukana kutentha kwabwino komanso kukana kwambiri mchere. Pansi pa mchere wina, ukhoza kukhalabe ndi mphamvu yabwino yochepetsera kutaya kwa madzi ndi rheology inayake. Pambuyo pakusungunuka m'madzi amchere, kukhuthala kwake kumakhala kosasinthika, makamaka koyenera kugwiritsa ntchito m'mphepete mwa nyanja. Kubowola ndi zofunika chitsime chakuya;

3. Ikhoza kulamulira bwino rheology ya matope, imakhala ndi thixotropy yabwino, ndipo ili yoyenera matope aliwonse amadzi m'madzi abwino, madzi a m'nyanja, ndi madzi amchere odzaza;

4. Kuphatikiza apo, PAC imagwiritsidwa ntchito ngati simenti yamadzimadzi, yomwe ingalepheretse madzi kulowa pores ndi fractures;

5. Filtrate yokonzedwa ndi PAC imatha kupirira yankho la 2% KCL (iyenera kuwonjezeredwa pokonza fyuluta) ndipo imakhala ndi kusungunuka kwabwino, kosavuta kugwiritsa ntchito, ikhoza kukonzedwa pamalopo, ndipo imakhala ndi liwiro lothamanga la gelation komanso luso lamphamvu lonyamula mchenga. Amagwiritsidwa ntchito pakupanga mapangidwe, ndipo zotsatira zake zosefera zamphamvu ndizabwino kwambiri.
