摘要

摘要: 近几年，在东地中海黎凡特盆地发现多个大型生物气田，成为常规油气资源新的接替领域。通过对黎凡特盆地生物气地球化学特征及成因类型判别，认为已发现的生物气主要为乙酸发酵成因的纯生物气。在对黎凡特大型生物气田成藏条件的系统性解剖和成藏规律总结的基础之上，提出大型生物气田的形成主要受4大地质因素控制，分别是充足的气源、广泛分布的优质砂岩储层提供的高效汇聚通道、继承性隆起带上发育的大型背斜圈闭和有利的储盖组合配置条件。继承性隆起带往往发育大型的同沉积背斜圈闭，广泛分布海底扇砂岩储层，是寻找大型生物气田的主要勘探方向。

Abstract: In recent years, a number of large biogas fields have been discovered in the Levantine Basin of the Eastern Mediterranean, becoming a new replacement for conventional oil and gas resources. The discovered biogas is mainly pure biogas produced by acetic acid fermentation based on the biochemical characteristics and biogenetic types of biogas. The summary of accumulation conditions and rules showed that the large biogas reservoirs in the study area were controlled by four geologic factors including sufficient gas source, extensive distribution of good sandstones providing efficient migration and charging pathways, constant uplift developing giant anticline traps and a favorable match between reservoir and seal. The belt of continuous uplift provides a favorable location for a giant trap and good reservoir.
