Tsvagiridzo pamusoro peZvishandiso Zvinowedzera Kumhanya Kwekubhoboza

Parizvino, maturusi anowedzera kumhanya kwekuchera akakamurwa zvikuru muzvikamu zviviri: mhando yemakanika uye mhando yehydraulic. Maturusi emakanika anoshandisa Weight on Bit (WOB) kugadzira simba rekurova, izvo zvinovandudza kushanda zvakanaka kwekupwanya matombo muzvikamu zvakaoma, asi kune matambudziko akadai sekubvunda kwakasimba, kushandiswa kwesimba rakawanda, uye kukuvara kuri nyore kuneta. Maturusi ehydraulic anoshandisa mvura yekubhoboza kutyaira hammer dzekurova, kubatanidza kupwanya, kutenderera uye jet kupwanya matombo. Ane mabhenefiti makuru mukuwedzera Rate of Penetration (ROP), kudzora kutsauka kwetsime uye kuwedzera hupenyu hwezvidimbu, asi kazhinji ane matambudziko akadai sekuwanda kwekukuvara kamwe chete uye kuoma kwekugadzirisa zvinodiwa zvezvikamu zvakasiyana.

Tekinoroji yekuchera impact yakakamurwa zvikuru muzvikamu zvitatu zvichienderana nenzira yekushanda: tekinoroji yekurova impact, tekinoroji yekurova axial uye tekinoroji yekurova axial-torsional composite. Chinangwa chekuchera impact kuwedzera kumhanya ndechekushandura simba rekumanikidza regasi kana mvura kuita simba remagetsi rekurova axial kana torsional kuburikidza ne impactor, iyo inoshandiswa zvakananga kumucheto wekumashure kwe bit, zvichivandudza mamiriro ekucheka kwe bit uye kuwedzera kushanda zvakanaka kwe bit.

Tekinoroji yekuboorera ine torsional inyanzvi iri kubuda iri kuwedzera kumhanya kwekuboorera mumakore achangopfuura, inonyanya kushandiswa kugadzirisa vibration ye "stick-slip" inogadzirwa nemaPDC bits. Kana ichishandiswa, torsional impactor inoiswa kumashure kwe bit. Kuburikidza nekugadzirwa kwayo kwemukati, inogona kushandura simba re hydraulic remvura kuita simba re torsional impact mechanical. Bit iyi inopwanya dombo pasi pekushanda kwakabatana kwe steady-state torque ye drill string uye torque ye impact inogadzirwa ne impactor.

1. Chishandiso Chinowedzera Kumhanya Kwekudhirowa Chine Kuchinja Kwekukanganisa

Chishandiso chinokwidza kumhanya kwedhirairi chinogona kugadziriswa frequency chine chimiro chepakati cheimpact chakagadzirwa nemabheringi, muviri wepasi weshaft, mapiston pairs, impact hammer, throttle nozzle nezvimwe zvikamu.

Nheyo yekushanda:Inoshandisa musiyano wekumanikidzwa kwenguva nenguva unoumbwa nemvura yekuboorera mumakamuri epamusoro neapasi ehammer yekubaya kuti ifambise hammer yekubaya kuti idzorere nekukurumidza, zvichigadzira simba rekurova rinotumirwa zvakananga kubhiti kuti ribatsire pakupwanya dombo. Chinokosha ndechekuti chishandiso ichi chinogona kugadzirisa frequency yekubaya nekuchinja huwandu hwemaburi akaenzana mumuviri weshaft wepazasi, nokudaro chichigadzirisa zvinodiwa zvekuboorera zvemaumbirwo akasiyana.

Kushandiswa kweChishandiso Chinowedzera Kumhanya Kwekudhirowa Chine Kugadziriswa Kwekukanganisa Kunogona Kugadziriswa

Kuedza Mumunda muKuumbwa Kwepakati Nepakati: Zvichibva pahuwandu hwemhedzisiro (16 Hz) hwakasarudzwa nekushandisa nhamba, chishandiso ichi chakaedzwa muWell X1 yeXinjiang Oilfield. Muchikamu chekugadzirwa kwacho chine abrasiveness yakasimba uye Rate of Penetration yakaderera (ROP), kuenzanisa netsime riri pedyo uchishandisa screw drill tool kunoratidza kuti mushure mekushandisa chishandiso ichi, footage yekumhanya kamwe chete yakawedzera ne53%, mechanical ROP yakawedzera ne27.0%, zvichideredza huwandu hwekufamba uye kuchengetedza nguva yekuvaka.

Kuedza Mumunda Mukugadzirwa Kwakaoma: Zvichienderana nefrequency yemhedzisiro yakanaka (18 Hz) yakasarudzwa nekushandisa nhamba, chishandiso ichi chakaedzwa muCarboniferous Andesite neBasalt formations pasina kubhoorwa zvakanaka muWell X3 yeXinjiang Oilfield.

Mhedziso: Zvakabuda zvinoratidza kuti mushure mekushandisa chishandiso ichi, ROP yemuchina yakawedzerwa zvakanyanya ne103.2% kana tichienzanisa nematsime ari pedyo, izvo zvinoratidza kuti inogona kuvandudza zvakanyanya kushanda zvakanaka kwekuchera nekupfupisa kutenderera kwekuchera muzvikamu zvakasiyana.

2. Kugadzirwa kweComposite Impact Drilling Tool Inowedzera Kumhanya

Nzira ye hydraulic torsional impact mechanism yakagadzirwa, ine centre ine zvikamu zvitatu: nzira yekugovera kuyerera kwemvura, nzira yekudzosera shure, uye nzira yekukanganisa.

Maitiro Ekufamba: Pakutanga (taura a), mvura ine simba repamusoro inopinda mugomba rekuruboshwe rehammer ye hydraulic kuburikidza negwara rekuyerera rekuruboshwe revharuvhu rinodzokera shure, ichisunda hammer ye hydraulic nepakati pevharuvhu kuti zvitenderere pamwe chete kusvika hammer ye hydraulic yarova chigaro chehammer ye hydraulic (taura b). Mushure mekurovera, mvura ine simba repamusoro inobva yapinda mugomba rekurudyi rakaumbwa nehammer ye hydraulic nepakati pevharuvhu kuburikidza negwara rekurudyi rekudzora, ichisunda vharuvhu kuti irambe ichitenderera newachi kuenda kunzvimbo yekudzokera shure (taura c), kuitira kuti mvura ine simba repamusoro ishandukire kune mugwagwa wekurudyi wekuyerera uye ipinde mugomba rekurudyi rehammer ye hydraulic, ichisunda hammer ye hydraulic nepakati pevharuvhu kuti zvitenderere newachi (taura c). Kusvikira hammer ye hydraulic yarova chigaro chehammer ye hydraulic zvakare (taura d), mvura ine simba repamusoro inopinda mugomba rekuruboshwe kuburikidza negwara rekudzora rekurudyi rekudzora, ichisunda vharuvhu kuti itenderere newachi kuti idzokere shure uye idzokere kumamiriro ekutanga (taura a). Izvi zvinotenderera, zvichigadzira torsional impact inodzokororwa ne high-frequency kuburikidza nekudzokera shure nekubata kunotungamirwa nemvura.

Nheyo yekushanda:Mushure mekunge mvura (matope) yayerera ichipinda muchikamu chekugovera mafambiro emvura kuburikidza nepajoini repamusoro nepombi yekutungamira, inoendeswa kune chinodzosera kumashure uye kune chinobaya, uye nzira mbiri dzemvura dzinoparadzaniswa neplate yekugovera mafambiro. Zvadaro, mvura inopfuura nemumuromo uri mukati me mandrel, ichigadzira nzvimbo dzekumanikidza dzakakwirira nedzishoma pamberi payo uye mushure mayo. Musoro wevharuvhu inodzosera shure unotenderera pasi pemusiyano wekumanikidza, uchidzora maburi ekuruboshwe nerudyi ehammer ye hydraulic kuti ubatanidzwe kune nzvimbo dzekumanikidza dzakakwirira nedzishoma, zvichiita kuti hammer ye hydraulic idzoke zvakare kuti irove chigaro chehammer ye hydraulic pasi pemusiyano wekumanikidza, nokudaro ichigadzira torsional impact yepamusoro-soro.

Maitiro Ekufamba kweTorsional Impact Mechanism

Rudzi rwenzira yekukanganisa axial rwakagadzirwa. Hydraulic axial impactors dzakakamurwa kuita mhando mbiri: rudzi rwevharuvhu nerudzi rusina vharuvhu. Maumbirwo emukati me valve-type impactors akaomarara uye kuvimbika kwawo hakuna kunaka; vharuvhu mhando inonyanya kusanganisira jet type ne jet-suction type, pakati padzo jet type ine hupenyu hupfupi hwebasa. Jet-suction hydraulic impactor ine chimiro chakareruka, inoita impact inoenderana ne jet entrainment uye water hammer oscillation effect, ine zvikamu zvishoma zvinofamba mukati uye haina zvikamu zvisina kusimba, uye inogona kuchinjika zviri nani kune mamiriro akaomarara ekudzika.

Kuumbwa Kwemusiyano Wekutanga Wekuyerera uye Kumanikidzwa: Mvura ine kumanikidzwa kwakanyanya inogadzira jet inomhanya zvikuru ichipinda nemumuromo wepamusoro. Pasi pekushanda pamwe chete kwejet entrainment uye throttling effect, musiyano wekumanikidzwa unoumbwa mumakamuri epamusoro neepasi evharuvhu repamusoro, pamwe nepakati pekamuri rekunze rekumusoro rehammer impact nemucheto wepasi wehammer head.

Kufamba Kwezvikamu Uye Kuvhara Nzira Dzekuyerera: Zvichitungamirirwa nekusiyana kwesimba razvo, vharuvhu repamusoro rinokwira kumusoro, uye zvikamu zveimpact (muromo wechipiri, nyundo yeimpact, uye musoro wehammer) zvinofambawo kumusoro kusvika muromo wechipiri wabata vharuvhu repamusoro wovhara nzira yekuyerera.

Kugadzirwa kweNyundo yeMvura uye Kufamba kweMajoini Achidzika: Kuvharwa kwenzira yekuyerera kwemvura ipapo ipapo kunokonzera kutenderera kweNyundo yemvura, uye kumanikidzwa kuri mukamuri kunokwira zvakanyanya, zvichisunda vharuvhu repamusoro nezvikamu zvinokanganisa kuti zvikurumidze kudzika pamwe chete.

Kukanganiswa Kwesimba uye Kudzoreredzwa Kwesimba: Mushure mekunge vharuvhu repamusoro rafamba kuenda kunzvimbo yepasi, zvikamu zvekukanganiswa zvinoramba zvichidzika pasi pasi pekusagadzikana, uye pakupedzisira zvinorova chigaro chehammer kuti zvipedzise kukanganiswa kweaxial. Mushure mekukanganiswa, nzira yekuyerera inodzokera pakunaka, uye mashandiro anogadziriswazve pasi pechiito cheWeight on Bit (WOB), zvichitanga kutenderera kunotevera.
