摘要/Abstract

摘要：

采用物理模拟实验对库车坳陷克拉2气田油气运聚进行了模拟,油气运聚的3个重要结论是:1)克拉2气田为深部生气-浮力驱动-逆冲断层、输导层运输-背斜或断背斜成藏,逆冲断层和输导层在克拉2气田成藏过程中起了重要的作用。2)克拉2构造不是一点供气,而是多源供气。3)多源天然气不断向上部的克拉2构造供气,从而造成气藏超压和高丰度的特性。下部与克拉2构造相似的两个由断层贯通的构造含气规模和丰度有限。

Abstract:

Physical simulation experiments have been performed for hydrocarbon migration and accumulation in Kela gas field in Kuqa depression, and the following 3 major understandings have been achieved:(1) In Kela 2 gas field, hydrocarbons have been generated in the deep source rocks, driven by buoyancy, migrated through thrust faults and carrier beds and accumulated in the anticlines or faulted anticlines. The thrust faults and carrier beds have played an important role in the reservoiring process of Kela 2 gas field. (2) The hydrocarbons in the Kela 2 structure have come from multiple sources rather than from a single source. (3) The gas from multiple sources have continuously accumulated in the Kela 2 structure above, resulting in the gas reservoir to be characterized by overpressure and high abundance. While the two deeper structures that are similar to Kela 2 structure and connected by faults have limited size and abundance of hydrocarbons.

Key words: physical simulation experiment, natural gas, reservoiring pattern, buoyancy, overthrust fault, Kela 2 gas field
