Abstract

Abstract:

The Shunbei No. 4 fault zone is located in the central part of the Shuntuoguole Low Uplift. The reservoir type in this zone is a condensate gas reservoir controlled by fracture zones. This type of reservoir is rare both domestically and internationally. The phase characteristics of the condensate gas reservoir exhibit a clear north-south differentiation. In-depth research on the phase characteristics and the main controlling factors of this differentiation can provide valuable insights for the exploration and development of similar condensate gas reservoirs. This study employed various technical methods, including PVT (pressure-volume-temperature) high-pressure physical property experiments, organic geochemical analysis, and fluid inclusion analysis and testing. The results showed that the crude oil in the Shunbei No. 4 fault zone was characterized by a low freezing point, low sulfur content, and medium-to-high wax content. Within the zone, natural gas exhibited differential distribution in terms of methane molar fraction, gas-oil ratio, gas dryness coefficient, and CO₂ molar fraction. PVT experiments indicated that the reservoir was a condensate gas reservoir with a large difference between formation pressure and dew-point pressure, classifying it as an unsaturated reservoir. The critical temperature and pressure in the northern section were significantly higher than in the middle and southern sections, showing a decreasing trend from north to south. From the perspective of hydrocarbon source rocks and reservoir formation, the differential enrichment of condensate gas reservoirs in the Shunbei No. 4 fault zone is primarily controlled by multiple sources of hydrocarbon supply and multiple phases of reservoir formation.

Key words: Shunbei oilfield, hydrocarbon accumulation, condensate gas reservoir, reservoir phase, hydrocarbon source rock
