Vagadziri vemichina yekuboorera mvura vachishandisa mapneumatic vanokuudza maitiro ekugadzirisa ivhu rakasiyana-siyana rinosanganikwa nemichina yekuboorera mvura.

Semugadziri wemidziyo yekuboora mvura ine simba remhepo, tinonzwisisa kuti michina yekuboora mvura ine simba remhepo inofanira kushandisa nzira dzakasiyana painosangana nemidziyo yakasiyana-siyana yejiyoloji mukuita kwekuchera kuti iwane mhedzisiro yakanaka. Midziyo yakasiyana yejiyoloji inofanirawo kuwanikwa, senge quicksand layer ne gypsum layer. Kana gypsum yapinda panguva yekuboora michina yekuboora mvura ine simba remhepo, calcium ions inogona kubviswa nekushandisa soda ash, kubvisa calcium uye kuderedza viscosity. Panguva iyi, chinhu chinoderedza viscosity chine simba rekudzivirira calcium chinogona kushandiswa kudzora viscosity uye kutsiva kushomeka kwechinhu chinoderedza kurasikirwa nefirita, chinhu chinodzivirira kuputsika nezvimwe zvinhu.

I. Gypsum layer

Usati wachera gypsum layer, mvura inocherwa mu rig inogadziriswa kare kuti ideredze chikamu chakasimba uye viscosity, uye mishonga inorwisa gypsum inosanganisirwa (semuenzaniso, soda ash, calcium remover, viscosity reducer, nezvimwewo). Uye zvichienderana nezvinhu zvekuvaka zvematsime ari pedyo, mushonga wekurapa gypsum layer unogadzirwa pachine nguva. Wedzera pH yemvura inocherwa mu rig yekuchera mvura, uye wobva wavandudza kugona kwemichina midiki yekuchera mvura kuti isasvibiswe ne gypsum.

Chechipiri, rukoko rwejecha rinokasira

Pakuchera mujecha remvura, zvakakosha kuvandudza viscosity yemvura inochera uye huwandu hwebentonite hwemvura inochera madziro, iyo inowanzo fanirwa kuva pamusoro pe10%. Kuti madziro ashande zvakanaka, kudonha kwejecha remvura kunodzikira mushure mekuderedza kuchinjika kwepurojekiti. Usati watanga kuchera, chikamu chinofanira kuvharwa nevhu gobvu rine viscosity inopfuura 80 kuitira kuti kuchera, kutema nemagetsi uye kuvharwa kwemichina midiki inochera madziro emvura kuenderane zvakanaka.

III. Dombo rejecha reQuartz

Kana dombo rejecha rikava dombo rakaoma kwazvo, kuchera kunowanzoita kuti kuchera kunonoke. Panogona kunge paine mamita maviri ejecha pakuchera mita imwe, maturusi ekuchera achisvetuka-svetuka zvine simba, kucheka kwetsvina yakawanda uye zvikanganiso zvekuchera zvakavigwa. Saka kunzwisisa kwakadzama kwenzvimbo kunodiwa.

Mvura yakachena haina mafuta akafanana nedhaka, uye maturusi ekuboorera ari mudombo rakaoma anosvetuka zvekuti dombo rinopwanyika kana maturusi ekuboorera achikwira; mvura yakachena ine simba guru rekutsvagisa, uye mvura inosuka haigone kutakura matumbu ematombo ari kukura kubva mugomba. Matumbu ematombo akaita sejecha anoramba achiyangarara uye achinyura mugomba. Kana chubhu yekuburitsa hupfu ikashandiswa, mita imwe kana mbiri yejecha inogona kuboorwa. Kusangwarira zvishoma kunogona kuviga chiboorera, uye jecha rakawanda richakonzera matambudziko akawanda pakubvisa gomba.

Dombo rejecha panguva yekushandiswa rinoumbwa nekuiswa uye idombo rakaoma kwazvo. Chigadziko chidiki chekuboorera mvura mutsime rinopinda mukati kana uchiboorera gomba racho hachina kudzika (303354200 m), saka kushandiswa kwakajairika kweboorera redhaimani drill bit clear water, otomatiki slurry, inowanzoonekwa muboorera zvishoma nezvishoma, mita imwe yeboorera inogona kuratidza mamita maviri ejecha, drilling tool jumping serious, slag, matombo akachekwa zvakanyanya, drilling failure yakavigwa nezvimwewo.

Mhinduro: Kana kuchera nevhu kusina mari yakawanda, unogona kuderedza kuitika kwejecha nekucheka huwandu hwemarigi ekuchera mvura mutsime diki, unogona kuwedzera nitro acid uye alkali zvinowedzera mumvura kuti zviite basa rekuti zvideredze kunyorovesa, kuitira kuti ugone kuderedza huwandu hwerigi dzinosvetuka uye jecha, wobva wanamatira pakucheneswa kwemaburi ekuchera erigi dzekuchera mvura mutsime, uye pakupedzisira kugadzirisa dambudziko!
