Abavelisi bemibhobho yokugrumba amanzi anepneumatic bakuxelela ukuba ujongane njani nemigangatho eyahlukeneyo yomhlaba ekudityanwa nayo ngamaqula okomba amanzi.

Njengomenzi wemibhobho yokugrumba amanzi anepneumatic, siyaqonda ukuba izixhobo zokugrumba zamanzi anepneumatic kufuneka zamkele iindlela ezahlukeneyo xa zidibana neeleyile ezahlukeneyo zejoloji kwinkqubo yokomba ukufumana iziphumo ezilungileyo. Kufuneka kuhlangatyezwane nemigangatho eyahlukeneyo yejoloji, njengomaleko wesanti ekhawulezayo kunye nomaleko wegypsum. Nje ukuba i-gypsum intrusion yenzeke ngexesha lenkqubo yokwemba i-pneumatic water well drilling rig, i-calcium ions inokususwa ngokuya kuthuthu lwesoda, ukususwa kwe-calcium kunye nokunciphisa i-viscosity. Okwangoku, i-agent yokunciphisa i-viscosity ene-calcium resistance resistance ingasetyenziselwa ukulawula i-viscosity-ukunciphisa kunye nokwenza ukusilela kwe-filter-ilahleko yokunciphisa i-agent, i-anti-collapse agent kunye nezinye izinto.

I. Umaleko weGypsum

Ngaphambi kokugrumba umaleko we-gypsum, ulwelo lokomba lwe-rig lunyanzelwa ukuba lunciphise isigaba esiqinileyo kunye ne-viscosity, kunye ne-anti-gypsum yonyango ebandakanyekayo (umzekelo, i-soda ash, i-calcium remover, i-viscosity reducer, njl.). Kwaye ngokwezinto zokwakha zamaqula angabamelwane, i-arhente yonyango yokunyanga i-gypsum layer ilungiselelwe kwangaphambili. Ukuphucula ixabiso le-pH lolwelo lokugrumba lwesixhobo sokomba samanzi, kwaye emva koko uphucule isakhono samanzi amancinci wokomba oomatshini bokugrumba ukuxhathisa ungcoliseko lwegypsum.

Okwesibini, umaleko wentlabathi ekhawulezayo

Xa ubhobhoza kwi-quicksand ukubunjwa, kuyimfuneko ukuphucula i-viscosity ye-drilling fluid kunye nomxholo we-bentonite we-water well drilling rig rig drilling fluid, efunekayo ngokubanzi ukuba ibe ngaphezu kwe-10%. Ukuze kuphuculwe ukusebenza kodonga lwe-water well drilling rig drilling fluid, ukukhukuliseka kwe-quicksand layer kuyancitshiswa emva kokunciphisa ngokufanelekileyo ukufuduka kwiprojekthi. Phambi kokuba uqalise ukugrumba, icandelo kufuneka livalwe ngodaka olungqindilili kunye ne-viscosity enkulu kune-80 ukuze kuqinisekiswe ukuqala okugudileyo kunye nokuyeka ukugrumba, ukugawulwa kombane kunye ne-casing yomatshini omncinci wokugrumba wamanzi.

III. Ilitye lentlabathi yequartz

Ukuba ixesha lesandstone lilitye elilukhuni kakhulu, kwinkqubo yokomba isoloko ibonakala inkqubela ecothayo yokomba. Kusenokubakho iimitha ezimbini zesanti xa kusomba imitha enye, izixhobo zokugrumba zitsiba ngamandla, ukusika kwe-slag ngaphezulu kunye neziphene zokugrumba. Ngoko ke ulwazi oluneenkcukacha lomhlaba luyafuneka.

Amanzi acwengileyo awanawo amandla okuthambisa afana nodaka, yaye izixhobo zokomba kwilitye eliqinileyo zitsiba kangangokuba ilitye liyaqhekeka xa izixhobo zokomba zitsibela phezulu; amanzi acwengileyo anepropathi enkulu yokuhlela, kwaye ulwelo olugungxulwayo alukwazi ukuthwala iitshiphusi zamatye ezikhulayo ziphuma emngxunyeni. Amaqhekeza amatye afana nesanti ahlala edada kwaye etshona emngxunyeni. Ukuba kusetyenziswa ityhubhu yokukhupha umgubo, iimitha enye okanye ezimbini zesanti zinokugrunjwa. Ukungakhathali okuncinci kunokulingcwaba i-drill, kwaye isanti eninzi iya kubangela ingxaki enkulu ekucoceni umngxuma.

Ilitye lentlabathi ngexesha lokufakwa kwesicelo lenziwa ngokubekwa kwaye lilitye elinzima kakhulu. Isixhobo esincinci sokugrumba samanzi esinepneumatic xa kusomba umngxuma awunzulu kangako (303354200 m), ngoko ke ukusetyenziswa ngokubanzi kwedayimane yokomba amanzi acwengileyo, udaka oluzenzekelayo, oluhlala lubonakaliswa ngokucotha ukomba, imitha enye yokomba inokubonisa iimitha ezimbini. kwesanti, isixhobo sokugrumba ukutsiba ngokunzulu, i-slag, ilitye elichithiweyo ngakumbi, ukusilela kokugrumba kungcwatywe njalo njalo.

Isisombululo: Ukuba ukugrumba ngodaka akunamali, unokunciphisa ukwenzeka kwesanti ngokusika ubungakanani bamanzi amancinci okugrumba izixhobo zokutsiba, unokongeza i-nitro acid kunye nezongezo zealkali emanzini ukuze udlale indima ye-vibration damping lubrication, ngoko ke. ukuba unokunciphisa inani lee-rigs zokutsiba kunye nesanti, kwaye emva koko unamathele ekucoceni imingxuma yokugaya i-pneumatic water well drilling rigs, kwaye ekugqibeleni uyisombulule ingxaki!
