  • Influenced by structures, reservoirs and accumulation conditions, the resistivity of the Paleogene condensate gas reservoir in the no.1 structure of the northern Luntai condensate gas reservoir was 1.3 Ω·m, which was lower than that of aquifers in gas reservoir of the Bashijiqike Formation in Cretaceous by 2.0 Ω·m. It led to the neglect of low-resistivity reservoirs in early exploration. The origin of low-resistivity oil and gas reservoirs in Paleogene in the Luntai area was studied. A new identification standard to distinguish low-resistivity reservoirs and aquifers was established, which led to a great discovery of condensate gas reservoir in Paleogene of well YL2.
