Kukula kwa minda ya mafuta ndi gasi ndi ntchito yovuta komanso yowonjezereka yopangidwa ndi kufufuza, kubowola, ntchito pansi pa nthaka, kubwezeretsa mafuta, kusonkhanitsa ndi kunyamula.Kuchuluka kwa mankhwala kumafunika pa ntchito iliyonse.

Monga chinthu chofunikira chothandizira pakuwunika kwa geological, zowonjezera zobowola zaphunziridwa ndikugwiritsidwa ntchito kwa zaka zambiri kunyumba ndi kunja, ndipo mazana azinthu zofananira zapangidwa.

Kubowola madzimadzi kumadziwikanso kuti kubowola matope. Ntchito yake ndikuthyola pachimake, kunyamula zodula, kuthira mafuta oziziritsa, kuwongolera kuthamanga kwa mapangidwe ndi kuteteza chitsime.Kusunga matope abwino ndi njira yofunikira yopititsira patsogolo kuthamanga kwa kubowola ndikuwonetsetsa chitetezo chapansi. , ndi kuchitira wothandizira ndi chinsinsi kuonetsetsa matope kukhathamiritsa.Drilling madzimadzi ndi kutsiriza madzimadzi mankhwala mankhwala nkhani pafupifupi theka la oilfield mankhwala.

Chowonjezera simenti simenti

1. Fluid loss agent

Zida zomwe zimatha kuchepetsa kusefera kwa simenti slurry zimatchulidwa pamodzi kuti zochepetsera kutaya madzi kwa simenti slurry.Pakadali pano, omwe amagwiritsidwa ntchito kwambiri ochepetsa kutaya madzi ndi monga polyacrylamide, carboxymethyl cellulose ndi ma organic acid.

1. Kokani chochepetsera (diluent, dispersant, water reducer, turbulence regulator)

Kupopa kwamphamvu kwa grout nthawi zambiri kumatha kubweretsa zotsatira zokhutiritsa.Kokani zochepetsera zimatha kuwongolera kutuluka kwa grout ndikuyambitsa chipwirikiti pamlingo wochepa wa mpope.Sulfomethyl tannin, tannin lye ndi sulfomethyl lignite ali ndi zotsatira zabwino zochepetsera kukoka muzinthu zina.

1. Thickening time regulator

Chifukwa cha kuya kosiyanasiyana kwa simenti, slurry ya simenti imayenera kukhala ndi nthawi yoyenera yokulirapo kuti ikwaniritse zofunikira kuti zigwire bwino ntchito.

Olamulira a nthawi yowonjezereka akuphatikizapo coagulant ndi retarding spines.A coagulant ndi chowonjezera chomwe chingapangitse simenti kulimbitsa mwamsanga, yomwe imagwiritsidwa ntchito kwambiri ndi calcium chloride, sodium chloride.Ammonium chloride, etc.Ogulitsa ndi zowonjezera zomwe zingathe kutalikitsa nthawi yolimba kapena yowonjezereka ya slurry ya simenti.Zomwe zimagwiritsidwa ntchito nthawi zambiri zimaphatikizapo lignosulfonates ndi zotumphukira zake, mchere wa hydroxycarboxylic acid (monga citric tartaric acid) ndi zotumphukira zake.

1. Specific gravity regulator

Malingana ndi mitundu yosiyanasiyana ya kupanikizika kwa mapangidwe, kusiyana kosiyana kwa simenti slurry kumafunika.Zowonjezera zomwe zingasinthe kachulukidwe ka simenti ya slurry zimatchedwa olamulira enieni a mphamvu yokoka, kuphatikizapo zowunikira zowunikira ndi zolemetsa. Zowunikira ndi bentonite (zomwe zimadziwikanso kuti kuchotsa nthaka), asphalt yolimba, etc. Wothandizira kulemera ali ndi barite, hematite, mchenga, mchere. ndi zina zotero.
