Kuyera Paunenge Uchichera MWD

Iko kushandiswa kwekuyera uye kutema matanda panguva yekuchera kwakura zvakanyanya mumakore gumi apfuura. Kushandiswa kwezvishandiso izvi zvakagadziridzwamafutauye indasitiri yegasi kuti ishandiswe munzvimbo dzakanyanya sedimentary depositional inofanira kuongororwa maererano nezvinangwa zvakagadzirirwa EGS masisitimu. Ngatitangei titsanangure zvinorehwa muchikamu chino nemashoko, tichiona kuti mutsetse uri pakati penzvimbo mbiri idzi unoramba usina kujeka.

• Kuyera Paunenge Uchichera (MWD):Zvishandiso zvinoyera downhole parameters ye bit interaction nedombo ndeye MWD tool. Zviyero izvi zvinowanzo sanganisira kuzununguka uye kuvhunduka, mwero wekuyerera kwemadhaka, kutungamira uye kona yebhiti, uremu pabhiti, torque pabit, uye downhole pressure.
• Kutema Paunenge Uchichera (LWD):Zvishandiso zvinoyera downhole maumbirwo parameters maLWD maturusi. Izvi zvinosanganisira gamma ray, porosity, resistivity uye zvimwe zvakawanda zvekuumba zvivakwa. Zviyero zvinowira mumapoka akati wandei anokurukurwa pazasi. Chiyero chekare uye pamwe chakanyanya kukosha maumbirwo anogona kungoitika (SP) uye gamma ray (GR). Nhasi imwe kana ese ari maviri emateki aya anoshandiswa zvakanyanya kuwirirana pakati pematanda. Magetsi kana kugadzirwa resistivity matanda ndeimwe kirasi yematanda anoshandiswa muoiri uye gasi kutema. Nekuda kwenhoroondo refu yematanda aya, marudzi akati wandei akashanduka. Nheyo yemagetsi yekirasi iyi yematanda ndeyekuyera conductivity kana resistivity yezvakasiyana geologic zvinhu uye zvinwiwa zviri mazviri. Iyo resistivity ye shales vs iyo yejecha rakachena inoisa miganhu yeyakanaka yemagetsi log. Mvura iri mukugadzirwa zvakare inoratidzwa muchiyero ichi sezvo mvura inofambisa kana yawanikwa muzvibhorani uye mafuta isiri. Iko kushandiswa kwemagetsi matanda ndeyekutsanangudza miganhu yemubhedha uye musanganiswa nemamwe matanda kuona gasi / mafuta / mvura mabatiro. Asi imwe kirasi yematanda ndeye density matanda. Aya matanda anoratidza kuumbwa kwehuwandu hwezvinhu zviri mugomba retsime. Aya matanda anoda ingave neutron kana gamma sosi, uye chaizvo kuyera gamma ray flux misiyano. Porosity maturusi imwe kirasi yezvakajairika matanda maturusi. Maturusi aya anowanzo shandisa kemikari kana ikozvino akajairika magetsi anogadzirwa neutron kufungidzira kuumbwa kweporosity. Sezvo matanda aya achiwanzo gadziriswa mujecha, limestone kana dolomite kutarisirwa kunofanirwa kutorwa kana kuyerwa kunoitwa mumhando dzakasiyana dzematombo. Chekupedzisira mumakore mashoma apfuura akati wandei maturusi ehunyanzvi akashanduka, aya anosanganisira akasarudzika ekugadzira kumanikidza ekuyedza maturusi ayo anogona kumhanya uchidhirowa, nyukireya magineti resonance maturusi, uye pulsed neutron spectroscopy maturusi kunyora chete anonyanya kufarirwa.

Chikonzero chekushandisa

Mumakore achangopfuura mutengo weavhareji oiri uye gasi gomba wakawedzera zvakanyanya, chikamu chekuwedzera kwemutengo uyu chave chichifambiswa nekudiwa kwekutevera zvakadzika uye zvakanyanya kuoma matura. Izvi zvinowedzera njodzi yekukundikana kwemakomba akacherwa mumatura aya. Sekuita kune njodzi yakawedzera, kushandiswa kweLWD uye MWD tekinoroji uye matekiniki akawedzera. Mukuongorora kwekupedzisira, sarudzo yekushandisa LWD neMWD zvishandiso zvinoenderana nekugadzirisa njodzi. Chirongwa cheEGS chinofambisa hunyanzvi hwekuchera geothermal munzvimbo itsva ine njodzi, kuongororwa kwehunyanzvi hweLWD neMDW kunofanirwa kuitwa kuona kushanda kwehunyanzvi uhu kune njodzi dzakatarisana nekuedza kutsva uku. Zvakakosha kuziva mumuenzaniso weEGS, muzviitiko zvakawanda hatisi kuzove tichiisa nzvimbo yedu yepamusoro mudombo regneous kana metamorphic sezvatakaita kare. Aya makomba akadzika anogona kutaridzika zvakanyanya seyechinyakare mafuta uye gasi gomba pakadzika pasi, tiine izvi mupfungwa tinotanga kuongorora mashandisirwo anogona kuitwa eLWD neMWD tekinoroji.

Iyo yekuzvitsvakira gyroscope inclinometer inogadzirwa neVigor ndechimwe chezvakanakisa zvigadzirwa munyika, inokwanisa kuyera uye kurekodha kwenguva yakareba yenguva-yepamusoro-tembiricha uye yakakwirira-kumanikidza nharaunda. Parizvino, Vigor's gyroscope inclinometer yakashandiswa munzvimbo dzemafuta muEurope, North America, Africa, Middle East neAsia nedzimwe matunhu, uye timu yeVigor yehunyanzvi hwehunyanzvi hwebasa yakaenda kunzvimbo yevatengi kuti iite sevhisi, uye mutengi akarumbidza zvikuru tekinoroji uye zvigadzirwa zveboka reVigor, uye anotarisira kuenderera mberi nekubatana nesu. Kana iwe uchifarira gyroscope, inclinometer kana masevhisi ekutema matanda, ndapota usazeza kubata neboka reVigor kuti uwane rubatsiro rwehunyanzvi hwehunyanzvi uye sevhisi yemhando yepamusoro.

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