Kubva pakuongorora kusvika pakusiiwa: iwo makuru matanho emafuta uye gasi munda wekusimudzira

Kugadzirira Phase

Usati watanga kuvandudzwa kwemunda wemafuta negasi, kunyatsoferefeta uye kuongorora kwakakosha.Nzira inowanzo shandiswa kutsvaga zviwanikwa zveoiri negasi, kuongorora kwekudengenyeka kwenyika kunosanganisira kutumira masaisai eruzha mumatombo, kazhinji uchishandisa seismic vibrator (yekuongorora onshore) kana pfuti yemhepo (yekuongorora kumahombekombe).Kana masaisai eruzha achipinda mumatombo, chikamu chesimba rawo chinoratidzwa nematombo akaomarara, asi simba rose rinoramba richidzika mune mamwe mativi.Simba rinoratidzwa rinoendeswa kumashure uye rinorekodhwa.Vashandi vekuongorora saka vanofungidzira nezvekugovewa kwemafuta epasi pevhu uye gasi rechisikigo, vanoona saizi uye matura eminda yeoiri negasi, uye kudzidza chimiro che geological.Pamusoro pezvo, nharaunda yepasi uye zvingangoitika zvengozi zvinofanirwa kuongororwa kuti ive nechokwadi chekuchengetedzwa kwemaitiro ekuvandudza.

Hupenyu hwenzvimbo yemafuta uye gasi inogona kukamurwa kuita zvikamu zvitatu:

Chikamu chekutanga (makore maviri kusvika matatu): Muchikamu chino, nzvimbo yemafuta negasi ichangotanga kugadzira, uye kugadzirwa kunowedzera zvishoma nezvishoma sezvo mari yekuchera uye nzvimbo dzekugadzira dzichivakwa.

Plateau period: Kana kugadzirwa kwadzikama, minda yeoiri negasi ichapinda munguva yedanga.Munguva iyi, kugadzirwa kunoramba kwakagadzikana, uye nhanho iyi ichagara makore maviri kusvika matatu, dzimwe nguva yakareba kana munda wemafuta negesi wakakura.

Decline phase: Munguva iyi, kugadzirwa kwemafuta negasi kunotanga kudzikira, kazhinji ne1% kusvika 10% pagore.Kana kugadzirwa kwapera, pachine mafuta akawanda uye gasi zvasara muvhu.Kuvandudza kudzoreredza, makambani emafuta uye gasi anoshandisa nzira dzekuvandudza dzekudzoreredza.Minda yemafuta inogona kuwana mitengo yekudzoreredza pakati pe5% ne50%, uye kuminda inongoburitsa gasi rechisikigo, chiyero ichi chinogona kunge chakakwira (60% kusvika 80%).
