Wakanga uchiziva here kuti kubva Gumiguru 15 kusvika Zvita 15, imwe yemakwikwi makuru epasirese mukuongorora kwe data data, iyo Rosneft Seismic Challenge, iri kuitika nemari yemubairo we 1 miriyoni rubles uye yekupedzisira muna Zvita 21 muMoscow?
Zvinotendwa kuti kupinda muindasitiri yemafuta, uko mihoro isiri yakaderera kune IT indasitiri, zvakaoma. Pane chimwe chokwadi mune izvi, nekuti munda wakanyatsojeka uye haufarire vanhu "kunze kwechiuno." Ichi chiitiko chine chinangwa chekuita kuti zvive nyore kune vadiki uye vane tarenda zvikwata zvinoshanda mukuzivikanwa kwemifananidzo uye muchina kudzidza kupinda munyika ino yepasi pevhu.
Ndiri kutumira nyaya iyi muchikamu che "I PR" nokuti: a) Ndinoda kubatsira vamwe vangu vanogara muUfa; b) Ini ndinotenda mune zvakakwirira zvikwaniriso zvevabiki. Uye zvichave zvakanaka kana vamwe vakasangana nevamwe. Panguva imwecheteyo, ini ndichapedza nguva shoma semuturikiri kubva kune tekinoroji kuenda kumunhu.
Saka dambudziko nderei?
Iro basa rinonzwika seizvi: "Kuzivikanwa kweiyo seismic horizons mune amplitude cube - segmentation yedata uchishandisa kucherechedzwa kwemufananidzo." Championship paBoosters.pro papuratifomu. Murongi isangano remubatanidzwa BashNIPIneft LLC, mumwe wevatungamiriri (zvinoshamisa zvakakwana) mumunda webudiriro. . Muenzaniso wemufananidzo webasa ravo rakabudirira kusimudzira uye - proprietary industry software yemasvomhu modelling uye kuongorora maitiro ekugadzira makatsemuka panguva yehydraulic fracturing.
Kuturikira basa muchiRussian
Pasinei nezita rinotyisa, basa rinouya pasi kuongororo yemifananidzo uchishandisa muchina kudzidza. Asi, semazuva ese, kune akawanda nuances.
Kuongorora kweSeismic ndiyo nzira huru yekuwana mafuta uye gasi. Iyo nzira yakavakirwa pakunakidzwa kwe elastic vibrations uye kunotevera kurekodha kwemhinduro kubva kumatombo. Aya mavibrations anopararira kuburikidza nekukora kwenyika, achidzokororwa uye kuratidzwa pamiganhu ye geological layers ine akasiyana siyana. Mafungu anoratidzwa anodzokera kumusoro uye anonyorwa. Iyo inobuda ndeye inonzi seismic cube, iyo inochekwa kuita mitsara yakatwasuka uye yakachinjika. Isu tinowana aya marudzi ezvikamu (michinjikwa uye interlines), anoratidza matombo ane akasiyana zvivakwa.
Basa revatori vechikamu nderekunyatso kuona uye kumaka aya matinji ehorizon mukati mese seismic cube zvichibva pakudzidziswa kwekutanga pa10% yecube. Hazvina kuoma izvozvi, handiti?
Uye zvino mumashoko anogamuchirwa kazhinji:
"Kuwirirana mukutsvagisa seismic kunonzwisiswa senzira yekuziva uye kuronda maratidziro anoonekwa, akasiyana seismic facies complexes (reefs, nezvimwewo) munguva, kudzika uye nzvimbo, pane seismograms uye yakazara nguva uye kudzika kwe data yekudengenyeka kwenyika.
Mukuita kwekutevera kunoratidza horizons, seti ye kinematic uye ine simba seismic hunhu inoshandiswa. Mukuongorora kwavo kwakaoma, kuwirirana kweinotaridza miganhu yefungu remasaisai muchadenga kunoitwa nekuronda iyo inonyanya kutaurwa extrema (kana shanduko kuburikidza ne0) yenzvimbo yemasaisai, uku ichinyanya kufunga nezvekufanana kwevakidzani vekudengenyeka kwenyika.
Panguva imwecheteyo, kutsetseka kwekuchinja panguva yekunyora kwekuuya kwemafungu kunotorwa. Mutsara unobatanidza maitiro ehunhu (extrema) yesaisai imwechete munzira dzakasiyana inowanzonzi in-phase axis. Masaisai akaratidzirwa anowanzo wiriraniswa pamwe neakanyanya kupatsanurwa zvakanyanya (zvikamu). Muchiitiko ichi, vaturikiri vanowanzoomerera kune musimboti - kubva kune yakavimbika kusvika kune isingavimbike.
Chekutanga, isu tichatsvaga horizons kuti munzvimbo yekudzidza yebasa inogona kutevedzwa zvine chivimbo pamusoro penzvimbo yakakura uye kuve neyakakodzera geological referensi. Maonero anotarisisa akadaro anowanzonzi mareferensi kana kuti mareferensi. Iwo maregioni marker. Kutevera kwavo nekududzira kwavo kunogona kuwedzera zvakanyanya kunzwisiswa kwezvinhu zvese seismic, tectonic nhoroondo, uye sedimentary mamiriro. "

Unoda rumwe ruzivo?
Kune huwandu hukuru hweruzivo rwekureva nezvenyaya iyi muchiRussia munenge chero maitiro. Kusanganisira paYouTube. Semuenzaniso, unogona kutaura yakanakisa vhidhiyo yekuona nezve otomatiki kucherechedzwa kweseismic horizons, yakaitwa pachena neKazan Center for Continuing Education yeInstitute of Geological and Geographical Technologies yeKFU.
Zvinoratidzika kwandiri kuti mushure meizvi, basa riri mudambudziko rinofanirwa kuve rakajeka.
Ok, chii chinoda kuitwa?
Kubva pane yekutanga 10% yeiyo seismic cube, yakatomisikidzwa nemuturikiri ane hunyanzvi, iwe unofanirwa kumaka zvimedu zvasara mudhata rekuyedza pamwe nemiganhu yemakirasi akatarwa ane iyo yakanyanya metric kukosha.
Chii chokushanda nacho?
Iko kunobva dataset itatu-dimensional seismic data array (yakapfupikiswa seismic attribute nguva cube). Sezvambotaurwa pamusoro, cube inogona kumiririrwa muchimiro che 2D vertical zvimedu: mitsara uye inlines.
Chidimbu chega chega chinoumbwa ne-one-dimensional vectors - traces ine hurefu hwe2562 milliseconds ine nhanho ye2 ms. Nhamba ye crosslines: 1896. Nhamba yeinlines: 2812.
Hwerengedzo yenhamba yekutevera> 5 miriyoni
Nhamba yemakirasi ezvikamu (kureva kupatsanurwa kwemarudzi): 8.
Ndiani anotarisirwa paSeismic Challenge?
Vanoronga vari kutsvaga nyanzvi kubva kumunda wekuongorora data kuti vatore chikamu. Nguva yacho ishoma uye dambudziko rakakodzera kune avo "vanotoziva." Vese vanhu uye zvikwata zvevanhu vanosvika vashanu vanogona kutora chikamu mukusarudzwa kwemakwikwi.
Ini ndinopinda sei?
Vatori vechikamu vanozvinyoresa pachavo kuburikidza newebhusaiti. pane Boosters.pro saiti. Zvinoenderana nenhamba, kubva munaNovember 4, 402 zvikwata zvakanyoresa kutora chikamu mumakwikwi.
Mazuva:
15.10.19 - 15.12.19 - kubata makwikwi
24.11.19/XNUMX/XNUMX - kupera kwemukana wekubatanidza zvikwata
15.10.19 - 01.12.19 - chikamu chekutanga chemakwikwi
02.12.19 - 15.12.19 - chikamu chechipiri chemakwikwi ezvikwata makumi matatu zvakanakisa kubva munharaunda yekutanga
21.12.19/10/XNUMX - mu-munhu kupfupisa uye kupa zvikwata gumi kubva kumutambo wechipiri muMoscow.
Kurongeka kwekupedzisira kunonakidza: kanzuru yenyanzvi inoongorora mabasa ekupedzisira, asi haina kukanganisa kusarudzwa kwevanokunda. Kugovewa kwevanopedzisa kunotemerwa zvichibva pamhedzisiro yechikamu chemakwikwi chinoenderana neakanakisa segmentation mhando metrics (Dice Metrics). Panguva imwecheteyo, vatori vechikamu vanogona kugamuchira imwe bhonasi yekuratidzwa kwakanakisa kwemhinduro yavo muhuwandu hwe50 rubles.
PS
Ini handisi murongi weiyi dambudziko, saka ini handigone kukwanisa kupindura mibvunzo zvakadzama mumhinduro. Kana vanhu veHabra vane mibvunzo / kufarira, saka ndinogona kukoka mumiriri wevanoronga uye vakomana kubva kune boosters kuti vataure.
