塔里木盆地东河砂岩垂向渗流研究

A Study of Vertical Flow Through the Donghe Sandstone in Tarim Basin

通过对塔里木盆地某井东河砂岩储层物性描述，发现主力产层东河砂岩存在明显的垂向渗流，并提出这类产层适合用水平井进行开采。同时研究了这类储层钻垂直井开采与钻水平井开采的产能比较，提出了水平井长度与提高产能的关系。水平井的开采结果证实了本文研究的结论。

Studying the physical properties of the Donghe sandstone penetrated by a well in the Tarim basin shows that there is an outstanding vertical flow in the Donghe sandstone,a main producing formation in the basin A suggestion is given to produce such reservoir by horizontal wells With a comparison of productivity of a vertical well and a horizontal well, a relationship between the length of horizontal well and its productivity is established The conclusion is verified by the production of a horizontal well
