摘要:
东非裂谷乌干达Albert湖盆北区不同油田的储层地温梯度存在较大差别,即使同一油田内部不同井区的地温梯度也存在很大差异。通过分析地温测试资料,总结归纳研究区现今地温梯度的分布规律及影响地温场差异分布的主控因素,并分析了区域原油物性差异分布特征及主要原因。结果表明:研究区地温是影响原油物性差异分布的主要因素,地温梯度由南往北整体呈逐渐减小趋势,影响地温梯度的主控因素是上覆盖层的泥岩厚度、泥质含量及断层分布模式。
Abstract:
The geothermal gradients of different oil fields in the northern region of Lake Albert Basin in the East African Rift Valley of Uganda are quite different,even the geothermal gradients in different well zones within the same oilfield are also very different. Based on the analysis of ground temperature test data,the distribution law of the current ground temperature gradient in the study area and the main controlling actors affecting the distribution of the differences in the ground temperature field are summarized,and the distribution characteristics and main reasons for the differences in the physical properties of crude oil in the region are also analyzed. The results show that the ground temperature in the study area is the main factor influencing the distribution of differences in crude oil physical properties,the geothermal gradient decreases gradually from south to north,and the main controlling factors affecting the geothermal gradient are the mudstone thickness,the shale content,and the distribution pattern of faults in the overlying layer.
