摘要/Abstract

摘要： 位于大庆长垣的喇、萨、杏油田气油比持续升高，且气油比、CH₄含量（干燥系数）呈现北高南低的分布，油田唯一的气顶并不位于构造的最高部位，天然气中CO₂碳同位素值显示为基底碳酸岩热解成因。这些现象表明长垣内部天然气处于非稳定状态，长垣天然气的变化与深部气有关。深部气首先进入长垣北端的喇嘛甸构造，再依次向南部的萨尔图、杏树岗构造推进，形成了长垣天然气北高南低的分布格局。研究结果表明，大庆长垣深部有一个巨大的气田，它不断地向长垣补充着天然气。

Abstract: The gas-oil ratio of Lamadian, Sartu and Xingshugang region in Daqing placanticline rose up continuously, and the higher saturation pressure, gas-oil ratio and the content of CH₄ in the north are higher than that of in the south, the only gas cap isn’t in the highest structure in placanticline and the carbon isotope values of CO₂ indicate the CO₂ is from pyrolysis of carbonate in the basement. These phenomenon indicate that the gas in placanticline is in a state of moving. The deep gas source enter into Lamadian structure firstly and goes to Sartu and Xingshugang structure gradually. The results shows that there is a giant gas field in the deep of Daqing Changyuan which continuously added natural gas fie.

Key words: Daqing placanticline, dissolved gas, gas-oil ratio, carbon isotope, dynamic mechanisms
