Kuvandudzwa kweminda yemafuta uye gasi ipurojekiti yakaoma uye yakazara inoumbwa nekuongorora, kuchera, kushanda pasi pevhu, kupora mafuta, kuunganidza uye kutakura.Kuwanda kwemakemikari kunodiwa mukushanda kwega kwega.

Sechinhu chakakosha chekubatsira chekuongorora geological, zvekuchera zvinowedzera zvakadzidzwa uye kushandiswa kwemakore mazhinji kumba nekune dzimwe nyika, uye mazana ezvigadzirwa zvine hukama akagadzirwa.

Drilling fluid inozivikanwawo sekuti drilling mud.Basa rayo nderokupwanya musimboti, kutakura zvidimbu, kuisa mafuta ekutonhora, kuenzanisa kuumbwa kwemaitiro uye kuchengetedza tsime.Kuchengetedza kushanda kwakanaka kwevhu inzira inokosha yekuvandudza kuchera nekukurumidza uye kuve nechokwadi chekuchengetedzwa kwepasi. , uye mumiririri wekurapa ndiyo kiyi yekuita kuti madhaka awedzere.Kuchera mvura uye kupedzisa fluid kurapwa vamiririri vanoverengera inenge hafu yeoilfield makemikari.

Cementing simenti additive

1. Fluid kurasikirwa mumiririri

Zvishandiso zvinogona kudzikisa kufirwa kwesement slurry zvinosanganiswa kunzi kurasikirwa kwemvura kunoderedza vamiririri ve simenti slurry.Parizvino, anowanzo kushandiswa kurasikirwa kwemvura ekudzikisa maajenti anosanganisira polyacrylamide, carboxymethyl cellulose uye organic acid makomisheni.

1. Dhova chinodzikisira (diluent, dispersant, water reducer, turbulence regulator)

Kubvongodza kubvongodza kwegrout kazhinji kunogona kuburitsa zvinogutsa.Drag reducers inogona kudzora kuyerera kwegrout uye kukonzera mhirizhonga kuyerera pane yakaderera pombi rates.Sulfomethyl tannin, tannin lye uye sulfomethyl lignite vane migumisiro yakanaka yekukwevera kuderedza mune imwe yehuwandu hwehuwandu.

1. Thickening nguva regulator

Nekuda kwekudzika kwakasiyana kwesamende, simende slurry inodiwa kuve nenguva yakakodzera yekukora kuti isangane nezvinodiwa zvekushanda kwakachengeteka.

Thickening time regulators zvinosanganisira coagulant uye retarding spines.A coagulant is a additive iyo inogona kuita kuti simende igadzikane nokukurumidza, inowanzoshandiswa calcium chloride, sodium chloride.Ammonium chloride, etc.Vatengesi vanowedzera zvinogona kuwedzera nguva yekuoma kana kuwedzera nguva ye simenti slurry.Zvinowanzo shandiswa retarders zvinosanganisira lignosulfonates uye zvinobva kwavari, munyu wehydroxycarboxylic acids (senge citric tartaric acid) uye zvinobva kwavari.

1. Specific gravity regulator

Zvinoenderana neakasiyana maumbirwo ekumanikidza mamiriro, iyo yakasiyana density ye simenti slurry inodiwa.The additives inogona kushandura density ye simenti slurry inonzi yakananga giravhiti regulators, kusanganisira lightening agents uye weighting agents.Lightening agents are bentonite (inozivikanwawo sokubvisa ivhu), hard asphalt, etc.Weighting agent ane barite, hematite, jecha, munyu. zvichingoenda zvakadaro.
