摘要
唐河低凸起处于南阳和泌阳两个富含油气凹陷的交界部位,八十年代期间根据二维地震资料部署的6口探井均未钻遇油气显示,后一直未系统开展构造特征及储层展布规律研究。通过分析地层厚度、岩性组合、泥岩颜色等平面变化特点,认为核桃园组具备油气储、盖条件,沉积时期为一水下继承性隆起,是牛三门次凹油气运移长期有利指向区;根据相邻区块油气显示厚度平面变化特点,分析确定了油气向唐河低凸起方向运移路径的两个优势通道,对唐河低凸起部位的滚动勘探及井位优化部署具重要的指导意义。
Tanghe low uplift is located at the junction of Nanyang and Biyang depressions rich in oil and gas.In the 1980s,six exploration Wells deployed according to 2D seismic data did not find oil and gas.Since then,there has been no systematic research on structural characteristics and reservoir distribution law.Based on the analysis of the plane variation characteristics of strata thickness,lithologic combination and mudstone color,it is considered that the Hetaoyuan Formation has the conditions for oil and gas storage and capping,and the sedimentary period is an underwater inherited uplift,which is the favorable direction area for oil and gas migration in Niusanmen Depression for a long time.According to the variation characteristics of oil and gas thickness in adjacent blocks,two advantageous routes of oil and gas migration to the direction of the tanghe low uplift are analyzed and determined,which has important guiding significance for rolling exploration and well location optimization in the tanghe low uplift.
