| 摘 要： | 从伊通盆地莫里青断陷地温和地压实测数据出发，应用地温一地压系统原理分析了莫里青断陷的地温场、地压场及温一压系统的特征，并结合构造分布格局分析了它们对油气分布的影响。研究表明：莫里青地区地温梯度总体较高，地温异常在平面上呈现西北低东南高的特征。地温场的分布对生油门限具有明显的控制作用，以2400m为界，深部发育弱异常高压，油气垂向运移力较弱，发育弱高压型复式温压系统。受温压系统和构造格局的影响，油气纵向上主要分布于下部弱高压型温压系统的中上部，横向上则主要集中在相对低能的温压分区内。 |

| Abstract: | Based on the measurements of ground temperature and pressure from Moliqing faulted sag in Yitong Basin,this paper analyzes the characters of ground temperature and geo-pressure field and T-P system of the sag by T-P system theory.Combined with the structure distribution pattern,their effects on hydrocarbon distribution have been also analyzed.The study demonstrates that the temperature gradient in the Moliqing area is high,and the temperature abnormity increases from NW to SE.Oil generation threshold is con... |
