Oil and gas accumulation mode of anticline belt in compressional basin: take Qigequan area, Qaidam basin for example

doi:10.7523/j.issn.2095-6134.2012.2.007

Abstract

Abstract:

Based on core and thin section observation, physical property analysis, and seismic interpretation in Qigequan area in western Qaidam, a new hydrocarbon accumulation mode in the anticline structure is proposed. Hydrocarbon moves mainly along the parallel direction in the wing and the crack in the axes. Hydrocarbon fills first the deep strata and then the shallow formation in the axes.

Key words: anticline, Qaidam basin, Qigequan oilfield, hydrocarbon accumulation mode

CLC Number:

P618.130.2
