Ukulinganisa Ngenkathi Umba i-MWD

Ukusetshenziswa kokulinganisa nokugawulwa ngenkathi kubhowa sekukhule kakhulu eminyakeni eyi-10 edlule. Ukusetshenziswa kwalawa mathuluzi athuthukisiweamafuthakanye nemboni yegesi ukuze isetshenziswe ikakhulukazi endaweni ye-sedimentary depositional kumele kuphenywe kubhekwa izinjongo ezibekelwe izinhlelo ze-EGS. Ake siqale sichaze ukuthi yini eshiwo kulesi sigaba ngamagama, sibona ukuthi umugqa phakathi kwalezi zindawo ezimbili uyaqhubeka nokufiphala.

• Ukulinganisa Ngenkathi Umba (MWD):Amathuluzi akala imingcele ye-downhole yokusebenzisana kancane nedwala ayithuluzi le-MWD. Lezi zilinganiso ngokuvamile zihlanganisa ukudlidliza nokushaqeka, izinga lokugeleza kodaka, isiqondiso ne-engeli yebhithi, isisindo kubhithi, i-torque kubhithi, nokucindezela kwe-downhole.
• Ukugawula Ngenkathi Umba (LWD):Amathuluzi akala imingcele yokwakhiwa kwe-downhole angamathuluzi e-LWD. Lokhu kufaka i-gamma ray, i-porosity, i-resistivity nezinye izakhiwo eziningi zokwakheka. Izilinganiso ziwela ezigabeni ezimbalwa okuxoxwe ngazo ngezansi. Izilinganiso zokwakheka ezindala futhi mhlawumbe eziyisisekelo kakhulu amandla azenzekelayo (SP) kanye ne-gamma ray (GR). Namuhla okukodwa noma kokubili kwalokhu kulandelelwa kusetshenziselwa kakhulu ukuhlobana phakathi kwamalogi. Izingodo zikagesi noma zokubunjwa kwe-resistivity ingesinye isigaba sezingodo ezisetshenziswa ekugawulweni kukawoyela negesi. Ngenxa yomlando omude walezi zingodo, izinhlobo eziningana ziye zavela. Isisekelo sikagesi saleli klasi lamalogi ukukala ukuqhutshwa noma ukumelana kwezinto ezihlukahlukene ze-geologic kanye noketshezi olukuzo. Ukumelana namashali uma kuqhathaniswa nesihlabathi esihlanzekile kusetha imikhawulo yelogi efanelekile kagesi. Uketshezi ekubunjweni kwalo kuboniswa kulesi silinganiso njengoba amanzi ehambisa amanzi lapho etholakala kuma-boreholes kanti uwoyela awekho. Ukusetshenziswa okuyisisekelo kwamalogi kagesi ukucacisa imingcele yebhedi futhi kuhlanganiswe namanye amalogi ukuze kunqunywe ukuthintana kwegesi/uwoyela/amanzi. Nokho elinye isigaba samalogi amalogi okuminyana. Lezi zingodo ziyinkomba yokuminyana kokubunjwa kwempahla emgodini womthombo. Lawa malogi adinga i-neutron noma umthombo we-gamma, futhi empeleni akale umehluko we-gamma ray flux. Amathuluzi e-porosity angelinye ikilasi lamathuluzi okugawula ajwayelekile. Lawa mathuluzi ngokuvamile asebenzisa amakhemikhali noma manje i-neutron evame ukukhiqizwa ngogesi ukulinganisa ukwakheka kwe-porosity. Njengoba lezi zingodo zivame ukulinganiswa ku-sandstone, ukunakekelwa kwe-limestone noma i-dolomite kufanele kuthathwe lapho izilinganiso zenziwa ngezinhlobo ezahlukene zamadwala. Ekugcineni kule minyaka embalwa edlule kuye kwavela amathuluzi akhethekile amaningi, lokhu kufaka phakathi amathuluzi okuhlola ingcindezi yokwakheka okukhethekile angasetshenziswa ngenkathi kubholwa, amathuluzi enuzi kazibuthe ezwakalayo, namathuluzi e-pulsed neutron spectroscopy ukuze kufakwe ohlwini aziwa kakhulu kuphela.

Isizathu sokusebenzisa

Eminyakeni yamuva nje izindleko ze-avareji yembobo kawoyela negesi ziye zanda kakhulu, ingxenye yalokhu kukhuphuka kwezindleko kuqhutshwa isidingo sokulandela izindawo ezijulile neziyinkimbinkimbi kakhulu. Lokhu kwandisa ubungozi bokwehluleka kwezimbobo ezibhojwe kulezi zindawo zokulondoloza imvelo. Njengokusabela ezingozini ezikhulayo, ukusetshenziswa kobuchwepheshe be-LWD ne-MWD nezindlela kuye kwanda. Ekuhlaziyeni kokugcina, isinqumo sokusebenzisa amathuluzi e-LWD nawe-MWD sincike ekulawuleni ubungozi. Uhlelo lwe-EGS luhambisa ubuciko bokumba i-geothermal endaweni entsha yengozi, ukuhlolwa kobuchwepheshe be-LWD kanye ne-MDW kufanele kwenziwe ukuze kutholwe ukusebenza kwalezi zindlela zobuchwepheshe ezingozini ezithile ezibhekene nalo mzamo omusha. Kubalulekile ukuqaphela kumodeli ye-EGS, ezimweni eziningi ngeke sibeke uqweqwe lwethu olungaphezulu lube yi-igneous noma i-metamorphic rock njengoba senzile esikhathini esidlule. Lezi zimbobo ezijulile zingase zibukeke njengembobo yakudala kawoyela negesi ekujuleni okungashoni, sinalokhu emqondweni siqala ukuhlola ukusetshenziswa okungenzeka kobuchwepheshe be-LWD ne-MWD.

I-gyroscope inclinometer yokuzifunela ekhiqizwa yi-Vigor ingenye yemikhiqizo engcono kakhulu emhlabeni, ekwazi ukulinganisa nokurekhoda isikhathi eside endaweni yokushisa ephezulu kanye nengcindezi ephezulu. Njengamanje, i-gyroscope inclinometer ye-Vigor isetshenziswe ezindaweni ze-oilfield eYurophu, eNyakatho Melika, e-Afrika, eMpumalanga Ephakathi nase-Asia nakwezinye izifunda, kanti ithimba le-Vigor lochwepheshe bezobuchwepheshe liye lavakashela indawo yekhasimende ukuze lithole isevisi esizeni, futhi ikhasimende lincome kakhulu ubuchwepheshe nemikhiqizo yeqembu le-Vigor, futhi libheke phambili ekuqhubekeni nokusebenzisana nathi. Uma unentshisekelo nge-gyroscope, i-inclinometer noma izinsiza zokugawula, sicela ungangabazi ukuthintana neqembu le-Vigor ukuze uthole ukwesekwa kobuchwepheshe obuchwepheshile kanye nesevisi yekhwalithi engcono kakhulu.
