Ikesi Lesicelo Sesikhungo Sokwelapha Igesi Yemvelo e-Changqing Oilfield

Umsebenzisi: Indawo Yokucubungula Igesi Yemvelo e-Changqing Oilfield

Njengeyunithi enkulu yokubuyisela igesi yemvelo e-China, indawo yokucubungula igesi yemvelo e-Changqing Oilfield iwumsebenzi obalulekile we-CNPC wokuthuthukisa ikhwalithi nokusebenza kahle. Ukufeza ukuhlinzekwa kwezinto zokusetshenziswa zenqubo yokukhiqiza i-ethylene kusuka ku-ethane ngokushesha ngangokunokwenzeka, iphrojekthi ayisebenzisi nje kuphela isiqandisi esiqandisini esithuthukile samazwe ngamazwe + isiqandisi sokunwetshwa + i-double gas overcooling + ukushisa okuphansi kwe-distillation "i-ethane ukutakula ubuchwepheshe obuyinhloko bomzimba, kodwa futhi yamukela ubuchwepheshe obuphambili ekuklanyweni kobunjiniyela kanye nokwakhiwa. isiteji sokuklama, "kanye nemodi ye-digital life cycledigital" imodi, ukuze kuzuzwe ukuphathwa kwedijithali nokukhalipha kwayo yonke inqubo yokuklama, ukuthenga, ukwakhiwa, ukusebenza nokugcinwa.

Ngemva kokuphothulwa kwesikhungo sokwelapha igesi yemvelo,ingakwazi ukucubungulwa minyaka yonke igesi yemvelo engama-cubic metres angu-20 billion, ukukhiqizwa konyaka kwe-ethane eyizigidi ezingu-1.05, amathani angu-450,000 kanye ne-hydrocarbon ekhanyayo ezinzile, okulingana nenani eliphumayo lensimu yasekhaya kawoyela ophakathi nendawo, kuphinde kuphawule ukuthi ukuthuthukiswa kwegesi yemvelo yaseChina akuqedanga nje ukuguqulwa kusukela ekuthuthukisweni okusekelwe esikalini kuya ekuthuthukisweni okusekelwe esikalini kuya ekuthuthukisweni okusekelwe esikalini kuya ekuthuthukisweni kwekhwalithi ephezulu. Uchungechunge lwezimboni lwe-CNPC eShaanxi.

Amanzi ajikelezayo avale isistimu yokupholisa yesikhungo sokucubungula igesi yemvelo isebenzisa ukupholisa komoya + ukupholisa amanzi ukupholisa amanzi ajikelezayo. Ngenxa yamanzi okupholisa amanzi ajikelezayo avaliwe ukupholisa umbhoshongo usebenzisa amanzi angaphansi komhlaba ngqo njengoba amanzi eyengeziwe, isistimu has ukuthambekela okusobala ukukala ngemva kokugxilisa ingqondo, futhi kulula ukufaka futhi banamathele ukupholisa umbhoshongo filler, idivayisi isifutho, namashubhu okushintshanisa ukushisa, okuthinta umphumela wokushintshana kokushisa, okuholela ekunciphiseni komehluko wangaphakathi wokujikeleza kwegazi kanye nomphumela olindelekile wokushintshanisa ukushisa awukwazi ukufezwa. Ngenxa yokunamathela kanye nokubekwa kwesikali kanye ne-biological slime, kulula ukubangela ukugqwala ngaphansi kwesikali. Ezimweni ezimbi kakhulu, kungase kubangele amaphuzu avuzayo kunqwaba yeshubhu yokushintshanisa ukushisa yombhoshongo wamanzi okupholisa. Ngemva kophenyo esizeni, kwatholakala ukuthi ukunwetshwa kwenzeka ohlelweni lwamanzi lwesifutho sokujikeleza kwangaphandle.

Ipharamitha yokuqapha: conductivity

Iconductivity of spray water replenishment is 2290μs/cm, futhi usawoti ophelele ngu-1705.08mg/L, omkhulu kuno-1000mg/L oklanyiwe. Lapho amanzi okufutha ehlala ehwamuka futhi amanzi ehlala egcwaliswa, ukuqhutshwa kwe-conductivity kuyanda kusuka ku-2290 μs/cm kuya ku-10140 μs/cm ngemva kwehora eli-1 lokusebenza, ukuhanjiswa kukhuphuke cishe izikhathi ezi-5, usawoti ophelele ukhuphuka usuka ku-1705.08mg/L uya ku-3880.07mg/L ingafinyelela ku-34900 μs / cm ngemva kwamahora angu-48 okusebenza, futhi isici sokuhlushwa sifinyelela izikhathi ezingaba ngu-30. Ngakho-ke, lapho izinga lokushisa lamanzi lesifutho lingekho ezingeni elijwayelekile kanye nokwelashwa kwekhwalithi yamanzi kungenziwanga, amanzi e-spray enza ukulinganisa okunzima kanye nosawoti ocwebezelayo emgqonyeni we-tube yokushintshanisa ukushisa kwamanzi, fafaza ipayipi eliyinhloko lamanzi, i-spray yokupholisa evaliwe kanye nomphumela wokushisa we-spray, i-spray encishisiwe yokupholisa kanye nomphumela wokushisa we-spray. i-filler ivinjiwe, okuholela ekungeneni kwevolumu yomoya onganele we-fan epholile emoyeni kanye nomphumela oncishisiwe wokupholisa umoya.

Ukuze kuxazululwe lezi zinkinga ezingenhla, inkampani ifake ithuluzi lokulinganisa i-inductive conductivity online embhoshongweni wayo wokupholisa ukuze iqaphe ukuqhutshwa kwamanzi okufuthwa ngesikhathi sangempela lapho ikhwalithi yamanzi yesifutho ingahlangabezani nezinga elijwayelekile kanye nokwelashwa kwekhwalithi yamanzi kungenziwanga, i-alamu icushiwe ukuze inikeze isisekelo esinembile sokwelashwa kwamanzi okulandelayo kanye nokufutha kabusha amanzi.

I-electrode conductivity inductive ekhiqizwa yi-Shanghai Boqu Instrument Co., Ltd., inebanga elikhulu lokulinganisa kanye nezici zokulwa nokungcoliswa, okuxazulula inkinga yokungcoliswa kwezinzwa okubangelwa usawoti omningi wamasampula amanzi esizeni, yehlisa umsebenzi wokusebenza endaweni kwabasebenzi abalungisayo, kanye nobubanzi bayo obukhulu kakhulu obungu-0-2000 odingekayo esizeni sesilinganiso/cm.
