康梁区块处于鄂尔多斯伊陕斜坡与天环凹陷交界带,现有的勘探及开发现状表明,该区延8油层组不属于致密型油藏;虽然工区砂体广泛发育,但仅有小范围区域内的砂体含油。通过对油藏特征及分布规律进行研究,认为延8段发育常规物性储层,能够形成规油水分异界面,油藏分布于砂体相对海拔高值区。因此对于该区周围延8段油藏的勘探,应在预测砂体分布的基础上寻找发现背斜或隆起构造以及上倾岩性尖灭区。
The present situation of exploration and development in Kangliang block is located at the junction of Yi-Shan slope and Tianhuan depression in Ordos. The results show that the Yan 8 block in the area is not a tight reservoir. Although the sand body in the area is widely developed, only a small area The sand bodies in the area are oily. By studying the characteristics and distribution of reservoirs, it is considered that the development of conventional physical reservoirs in Yan 8 can form a profiled oil-water interface, and the reservoirs are distributed in the relatively high altitude area of sand body. Therefore, for exploration of 8 reservoirs around the area, the discovery of anticline or uplift structure and up-dip lithic pinch out area should be based on the prediction of sand body distribution.
