摘要

西湖凹陷西部斜坡带油气藏整体呈现“小、断、贫、散”的特征，综合利用录井、测井、地震、生产等多种资料，分析总结西部斜坡带已发现油气的分布规律，提出西部斜坡带具有“南北分区、上下分层、近源富集”的油气分布特点。通过西部斜坡带典型油气藏解剖和失利井地质原因分析，认为圈闭和运移是油气成藏的主控因素。构造样式决定圈闭的类型和有效性，进而控制了不同区域的油气藏类型和差异富集；不同油气运移模式和两期充注、蒸发分馏作用控制了研究区近源成藏和“上油下气”的特征。通过成藏条件分析，指出平湖斜坡潜山、天台斜坡北段和杭州斜坡迎翠轩断裂带具有较好的圈闭和运移条件，是西湖凹陷西部斜坡带的勘探新领域。

Abstract

The western slope zone of Xihu Sag is characterized by "small, faulted, poor and scattered". A comprehensive utilization of various data such as geological logging, well logging, seismic and production has been conducted to summarize the distribution patterns of oil and gas discovered in the western slope zone. It is believed that the western slope zone has the characteristics of oil and gas distribution of "north-south zoning, upper-lower stratification, near source enrichment". By dissecting typical oil and gas reservoirs and analyzing the geological reasons of the failed wells in the western slope zone, it is believed that traps and migration are the main controlling factors for oil and gas accumulation. Structural styles determine the type and effectiveness of the trap, and control the types of oil-gas reservoir and differential enrichment in different zones. The different migration of oil and gas, as well as the two-stage filling and evaporation fractionation, control the characteristics of near source accumulation and upper oil and lower gas in the study area.By analysis of reservoir forming condition, it is pointed out that buried hill of Pinghu slope, north section of Tiantai slope and Yingcuixuan fault belt of Hangzhou slope have better trap and migration conditions, which are new exploration directions of the western slope zone in Xihu Sag.

Key words： hydrocarbon accumulation; trap type; main controlling factors; exploration field; western slope zone; Xihu Sag
