Gyro Survey Tool Types MuOiri & Gasi Matsime

Conventional Gyro

Iyo yakajairika gyro kana yemahara gyro yanga iripo kubva kuma1930s. Iyo inowana iyo azimuth yetsime kubva kune inotenderera gyro. Inongotarisa kutungamira kwegomba uye haitarise kurerekera. Iyo inclination angle inowanzowanikwa ne accelerometers. Iyo firimu-based, single-shot gyro inoshandisa pendulum yakamiswa pamusoro pekambasi kadhi (yakasungirirwa kune yekunze gimbal axis) kuti iwane kurerekera. Gyro yakajairwa ine huremu hwekutenderera hunowanzo kutendeuka pa20,000 kusvika 40,000 rpm (vamwe vanotendeuka nekukurumidza). Iyo gyro icharamba yakagadzikana kana pasina masimba ekunze anoshanda pairi uye misa inotsigirwa panzvimbo yayo chaiyo yegiravhiti. Nehurombo, hazvigoneke kuchengetedza huwandu huri panzvimbo yayo chaiyo yegiravhiti, uye masimba ekunze anoita pane gyro. Naizvozvo, iyo gyro ichakukurwa nekufamba kwenguva.

Nechepfungwa, kana gyro ikatanga kutenderera uye inongedzerwa kune imwe nzira, haifanirwe kuchinja zvakanyanya nzira nekufamba kwenguva. Naizvozvo, inomhanyiswa mugomba, uye kunyangwe nyaya yacho ichitenderera, gyro yakasununguka kufamba, uye inoramba ichinongedza munzira imwechete. Sezvo nhungamiro iyo gyro inonongedza ichizivikanwa, kutungamira kwegomba kunogona kutariswa nemusiyano pakati pekutarisa kwegyro uye kutaridzika kwenyaya ine gyro. Mamiriro eiyo spin axis anofanirwa kuzivikanwa gyro isati yaitwa mugomba. Izvi zvinonzi referencing the gyro. Kana iyo gyro isina kutaurwa nemazvo, ongororo yese yakadzimwa, saka chishandiso chinofanirwa kutariswa nenzira kwayo chisati chapinzwa mugomba remafuta negasi.

Zvakaipa

Chimwe chinokanganisa cheyakajairika gyro ndechekuti inodonha nekufamba kwenguva, ichikonzera zvikanganiso mune yakayerwa azimuth. Iyo gyro ichakukurwa nekuda kwekukatyamadzwa kwehurongwa, kutakura kupfeka, uye kutenderera kwePasi. Iyo gyro inogona zvakare kukukurwa nekuda kwekusakwana mu gyro. Izvo zvinokanganisa zvinogona kukura panguva yekugadzira kana machining ye gyro, sezvo chaiyo nzvimbo yehuremu isiri pakati peiyo spin axis. Kukukurwa kushoma paEquator yepasi uye kumusoro panzvimbo dzakakwirira pedyo nematanda. Kazhinji, magirosi akajairwa haashandiswe pa latitudes kana kurerekera pamusoro pe70°. Chiyero chakajairwa chekudonha cheiyo gyro yechinyakare ndeye 0.5 ° paminiti. Iko kudonha kuri pachena kunokonzerwa nekutenderera kwePasi kunogadziriswa nekuisa simba rakakosha kune yemukati gimbal ring. Simba rinoshandiswa rinoenderana nelatitude ichashandiswa gyro.

Nekuda kwezvikonzero izvi, ese akajairwa gyros anokukurwa nemari chaiyo. Kudhiraivha kunotariswa pese panoitwa gyro yechinyakare, uye ongororo yacho inogadziridzwa kune iyo yekudonha. Kana iyo referensi kana kudhiraivha isina kubhadharwa zvakaringana, iyo yakaunganidzwa ongororo data ichave isiriyo.

Rate Kubatanidza Kana Kumaodzanyemba-Kutsvaga Gyro

Chiyero kana kuchamhembe-inotsvaga gyro yakagadzirwa kudzivirira kukanganisa kweiyo yakajairika gyro. A rate gyro uye kuchamhembe-inotsvaga gyro zvinhu zvakafanana. Iyo gyro ine dhigirii imwe chete yerusununguko. Muyero wekubatanidza gyro unoshandiswa kuona chokwadi Maodzanyemba. Iyo gyro inogadzirisa kutenderera kwePasi kuita zvikamu zvakati sandara uye zvakamira. Chikamu chakachinjika chinogara chichinongedzera kuChamhembe kwechokwadi. Kudiwa kwekutarisa gyro kunobviswa, izvo zvinowedzera kururamisa. Latitude yetsime inofanira kuzivikanwa nekuti Earth spin vector ichasiyana sezvo latitude inosiyana.

Panguva yekuseta, mwero wegyro unoyera kutenderera kweNyika kuti ibvise kudonha kunokonzerwa nekutenderera kweNyika. Ichi chimiro chekugadzira chinoita kuti isaite mukana wekuburitsa zvikanganiso zvichienzaniswa neyakajairwa gyro. Kusiyana neyechinyakare gyro, mwero wegyro haudi nzvimbo yereferensi kuti ionekwe mukati, nekudaro kubvisa imwe inogona kukanganisa kukanganisa. Masimba ari kushanda pagyro anoyerwa nawo, ukuwo simba regiravhiti richiyerwa neaccelerometers. Izvo zvakasanganiswa kuverenga kweaccelerometers uye gyro inobvumira kuverenga kwekuteterera uye azimuth yetsime.

A rate gyro inoyera iyo angular velocity kuburikidza neangular displacement. Muyero wekubatanidza gyro unoverengera kubatanidzwa kweangular velocity (angular displacement) kuburikidza nekubuda kweangular displacement.

Nyowani shanduro dzegyro dzinogona kuongororwa uchifamba, asi zvinogumira zviripo. Ivo havafanirwe kuramba vakamira kuti vawane ongororo. Yese nguva yekuongorora inogona kudzikiswa, zvichiita kuti chishandiso chiwedzere kudhura.

Ring Laser Gyro

Iyo ring laser gyro (RLG) inoshandisa rudzi rwakasiyana rwegyro kuona kwakananga kwetsime. Iyo sensor inosanganisira matatu-mhete laser gyros uye matatu inertial-giredhi accelerometers akaiswa kuyera X, Y, uye Z axes. Yakanyatsojeka kupfuura chiyero kana kuchamhembe-inotsvaga gyro. Chishandiso chekuongorora hachifanirwe kumiswa kuti utore ongororo, saka ongororo dzinokurumidza. Nekudaro, iyo dhayamita yekunze yemhete laser gyro ndeye 5 1/4 inches, zvinoreva kuti gyro iyi inogona kungomhanya mu7 ″ uye hombe casing (tarisa yeducasing designgwara). Haikwanise kufambiswa neadrill tambo, nepo chiyero kana kuchamhembe-inotsvaga gyro inogona kumhanya nepakati pechibhorani tambo kana diki dhayamita tubing tambo.

Zvikamu

Mune chimiro chayo chakareruka, iyo ring laser gyro ine triangular block yegirazi yakadhirowewa matatu helium-neon laser bores ane magirazi pa120-degree point - makona3. Counter-inotenderera laser matanda - imwe yakatarisana newachi uye imwe inopesana-wachi inopindirana mune ino resonator. Pane imwe nguva, photosensor inotarisisa matanda painopindirana. Iwo achapindira nenzira inovaka kana kuti inoparadza kune imwe neimwe, zvichienderana nechikamu chaicho chedanda rimwe nerimwe.

Kana iyo RLG yakamira (isina kutenderera) maererano nepakati axis, chikamu chehukama chematanda maviri chinogara chiripo, uye detector inobuda inowirirana. Kana iyo RLG ichitenderedzwa nezve axis yayo yepakati, iyo clockwise uye counter-clockwise matanda achasangana anopikisa Doppler shift; imwe ichawedzera muhuwandu, uye imwe ichaderera muhuwandu. Iyo detector inonzwa mutsauko frequency kubva kune chaiyo angular chinzvimbo uye velocity inogona kutsanangurwa. Izvi zvinozivikanwa seSagnac effect.

Chiri kuyerwa ndicho chikamu cheangular velocity kana kona yakatenderedzwa kubva pakatanga kuverenga. Iyo angular velocity ichave yakabva kune iyo frequency yebhiti. Iyo mbiri (quadrature) detector inogona kushandiswa kutora kutungamira kwekutenderera.

Inertial Giredhi Gyro

Chishandiso chakanyanya chekuongorora mumunda weoiri uye gasi ndiyo inertial giredhi gyro, inowanzonzi Ferranti chishandiso. Ndiyo yese navigation system seyakagadziriswa kubva kune aerospace tekinoroji. Nekuda kwekunyanya kurongeka kweiyi gyro, maturusi mazhinji ekuongorora anofananidzwa nawo kuti aone iwo echokwadi. Chishandiso chinoshandisa matatu chiyero gyros uye matatu accelerometer akaiswa papuratifomu yakagadzikana.

Iyo sisitimu inoyera shanduko munzira yepuratifomu (platform rigs) uye chinhambwe chainofamba. Iyo haingoyere kurerekera uye kwakananga kwetsime asiwo inotara kudzika. Haishandise kudzika kwewaya. Nekudaro, ine yakatokura chiyero che10⅝ inch OD. Nekuda kweizvozvo, inogona chete kumhanya mumakesi saizi e13 3/8 ″ uye yakakura.

Iyo gyroscope inclinometer kubva kuVigor inoedzwa nenzira iri nyore uye iri nyore kushandisa, uye mutengi anongoda chete kuisa nekuigadzirisa zvinoenderana nevhidhiyo yeVigor mushure mekugamuchira zvinhu. Kana iwe uchida rubatsiro rwedu, dhipatimendi reVigor mushure mekutengesa richapindurawo maawa makumi maviri nemana kuti ikubatsire kugadzirisa dambudziko racho nokukurumidza, kana iwe uchida Vigor's gyroscope inclinometer, tapota usazeza kutaurirana neboka rejinjiniya reVigor kuti uwane zvakanyanya. tekinoroji yehunyanzvi uye yakanakisa mhando yekushushikana-isina yemhando yepamusoro sevhisi.

Kuti uwane rumwe ruzivo, unogona kunyorera kubhokisi redu retsambainfo@vigorpetroleum.com&marketing@vigordrilling.com
