库车坳陷克拉2气田超压成因研究

物理实验模拟是研究油气运移和聚集的重要手段和方法。而天然气物理模拟实验则是一个研究相对不足而又非常重要的领域，它的操作和完善可以大大促进中国西部天然气勘探，直接影响着西气东输的国策。本文正是涉及这个领域，选取库车坳陷克拉2气田作为研究对象，模拟了其成藏模式，对其超压的特性进行了研究，认为构造挤压和充气增压是引起克拉2气田超压的主要原因，而充气增压的具体机制则是多级补给，也就是下部的冲起构造作为供源为上部的克拉2构造供气，促使其丰度和压力都升高。

A Study of the Overpressures of the Kela-2 Gas Field in Kuqa Depression

Physical modeling experimentation is an important method for studying the second migration and accumulation of oil and gas. In recent years, many experiments have been done to test some principles of the second migration and accumulation. Nevertheless, the level of gas simulation is by far lower than that of oil simulation. This paper focuses its attention on the gas reservoir closely related to the economic development and describes the experiment on the Kala-2 gas field reservoir. The overpressures of this reservoir is also studied. Many important conclusions have been drawn concerning the main reasons for the overpressures of the Kala-2 gas field. The mechanism of the overpressures seems to be multilevel supply.
