引言 钻水平井及高角度斜井在油气田开发中已经成为常规技术。水平井能以较大的面积接触储集层。因而,它们具有较高的产能。 高角度斜井及水平井似乎已成为油气田评价的工具,因为它们能够获取侧向特征及储层尺度等有价值的信息(Robertson等,1992)。根据垂向井间的关系不一定能取得这些信息,这在非均匀地层中尤为明显。
Introduction Drilling horizontal wells and high-angle inclined wells have become routine technologies in the development of oil and gas fields. Horizontal wells can contact reservoirs with larger areas. As a result, they have higher capacity. High-angle inclined wells and horizontal wells appear to have become tools for oil and gas field evaluation because of their ability to capture valuable information such as lateral features and reservoir dimensions (Robertson et al., 1992). Depending on the relationship between vertical wells, this information may not necessarily be available, especially in non-uniform formations.
