Umlinganiselo Ngelixa Kugrunjwa i-MWD

Ukusetyenziswa komlinganiselo kunye nokugawulwa kwemithi ngelixa kusomba kukhule kakhulu kule minyaka ili-10 idlulileyo. Ukusetyenziswa kwezi zixhobo eziye zaphuhliswaiolikunye neshishini lerhasi elizakusetyenziswa kwindawo ezidityanisiweyo kwintlenga kufuneka iphandwe ngokweenjongo ezibekelwe iinkqubo zeEGS. Masiqale sichaze okuthethwa kweli candelo ngamabinzana, siqonda ukuba umgca phakathi kwezi ndawo zimbini uyaqhubeka nokufiphala.

• Umlinganiselo Ngexa Kugrunjwa (MWD):Izixhobo ezilinganisa iparameters zomngxuma wemingxuma yokudibana kwebit kunye nelitye sisixhobo se-MWD. Le milinganiselo ibandakanya ukungcangcazela kunye nokothuka, isantya sokuqukuqela kodaka, intsingiselo kunye ne-engile yebit, ubunzima kwibit, i-torque kwi-bit, kunye noxinzelelo lwe-downhole.
• Ukugawulwa Ngeemithi Ngexa Kugrunjwa (LWD):Izixhobo ezilinganisa iiparamitha zokubunjwa komngxuma osezantsi zizixhobo ze-LWD. Ezi ziquka i-gamma ray, i-porosity, i-resistivity kunye nezinye izinto ezininzi zokwakheka. Imilinganiselo iwela kwiindidi ezininzi ezixoxwe ngezantsi. Eyona milinganiso midala kwaye mhlawumbi isisiseko sesakhono sesakhono (SP) kunye ne-gamma ray (GR). Namhlanje enye okanye yomibini yale mikhondo isetyenziswa ikakhulu kunxulumano phakathi kweelog. Umbane okanye ukubunjwa kwe-resistivity logs yenye iklasi yeelogi ezisetyenziselwa ukugawulwa kweoli kunye negesi. Ngenxa yembali ende yezi zigodo, iindidi ezininzi ziye zavela. Isiseko sombane solu didi lwezigodo kukulinganisa i-conductivity okanye resistivity yezinto ezahlukeneyo ze-geologic kunye nolwelo kuzo. I-resistivity of shales vs leyo yesanti ecocekileyo ibeka imida yelog yombane efanelekileyo. Ulwelo ekubunjweni nalo lubonakaliswe kulo mlinganiso njengoko amanzi eqhuba xa efunyenwe kumaqula kwaye i-oyile ingekho. Ukusetyenziswa okusisiseko kweelogi zombane kukuchaza imida yeebhedi kunye nokudibanisa nezinye iilogi ukumisela uqhagamshelwano lwegesi / ioli / amanzi. Ukanti olunye udidi lweelog ziilogi zokuxinana. Ezi zigodo zibonisa ukuxinana kokwakheka kwezinto kwiqula lomthombo. Ezi zigodo zifuna i-neutron okanye umthombo we-gamma, kwaye ngokwenene ukulinganisa i-gamma ray flux umahluko. Izixhobo ze-Porosity lolunye udidi lwezixhobo eziqhelekileyo zokugawulwa kwemithi. Ezi zixhobo ziqhele ukusebenzisa imichiza okanye ngoku neutron eqhelekileyo eveliswa ngombane ukuqikelela ukubunjwa kweporosity. Ekubeni ezi zigodo ziqhele ukulinganiswa kwilitye lesanti, i-limestone okanye ukhathalelo lwe-dolomite kufuneka luthathwe xa imilinganiselo yenziwa kwiintlobo zamatye ahlukeneyo. Okokugqibela kule minyaka imbalwa idlulileyo izixhobo ezikhethekileyo ziye zavela, ezi zibandakanya izixhobo ezikhethekileyo zovavanyo loxinzelelo ezinokuthi ziqhutywe ngelixa kusonjwa, izixhobo zenyukliya zemagnetic resonance, kunye nepulsed neutron spectroscopy izixhobo zokudwelisa kuphela ezona zidumileyo.

Ingqiqo yokusetyenziswa

Kwiminyaka yakutshanje ixabiso le-oyile kunye nomngxuma wegesi liye landa kakhulu, inxalenye yokunyuka kweendleko iqhutywe yimfuneko yokulandela oovimba obunzulu kunye nobunzima. Oku kwandisa umngcipheko wokungaphumeleli kwemingxuma egrunjwayo kula magcino. Njengokusabela kwingozi eyongeziweyo, ukusetyenziswa kwe-LWD kunye ne-MWD ubuchwepheshe kunye nobuchule kuye kwanda. Kuhlalutyo lokugqibela, isigqibo sokusebenzisa izixhobo ze-LWD kunye ne-MWD sixhomekeke ekulawuleni umngcipheko. Inkqubo ye-EGS ihambisa ubugcisa bokugrumba i-geothermal kwindawo entsha yomngcipheko, uvavanyo lwe-LWD kunye nobuchwepheshe be-MDW kufuneka lwenziwe ukumisela ukusebenza kobu buchwepheshe kumngcipheko othile ojongene nawo kulo mzamo mtsha. Kubalulekile ukuqonda kumzekelo we-EGS, kwiimeko ezininzi asizukubeka umphezulu wecasing yethu ibe yi-igneous okanye i-metamorphic rock njengoko besenza ngaphambili. Le mingxuma enzulu inokujongeka ngakumbi njenge-oyile yakudala kunye nomngxuma werhasi kubunzulu obunzulu, ngoku engqondweni siqala ukuvavanya usetyenziso olunokwenzeka lwe-LWD kunye nobuchwepheshe be-MWD.

I-gyroscope inclinometer yokuzimela eveliswa yi-Vigor yenye yezona mveliso ezilungileyo kwihlabathi, ezikwazi ukulinganisa kunye nokurekhoda ixesha elide kwiindawo eziphakamileyo zokushisa kunye noxinzelelo oluphezulu. Okwangoku, iVigor's gyroscope inclinometer isetyenzisiwe kwiindawo zeoyile eYurophu, kuMntla Melika, eAfrika, kuMbindi Mpuma naseAsia nakweminye imimandla, kwaye iqela lenkonzo yobuchwephesha beVigor liye laya kwindawo yabathengi ngenkonzo yesayithi, kunye umthengi uye wancoma kakhulu iteknoloji kunye neemveliso zeqela Vigor, kwaye ujonge phambili intsebenziswano ngakumbi nathi. Ukuba unomdla kwi-gyroscope, i-inclinometer okanye iinkonzo zokugawulwa kwemithi, nceda unganqikazi ukudibanisa neqela le-Vigor ukuze ufumane inkxaso yezobuchwepheshe obuchwephesha kunye nenkonzo esemgangathweni.
