水平井的广泛应用使水平井的问题日益受到重视.实际上在海上油气田开发中,总是尽可能多地采用水平井开采.考虑面积井网条件下水平井和直井联合开采的情形,假定中心一口直井作为注入井,而周围部署若干口水平井作为采油井.文中利用等值渗流阻力法导出多口水平井开发单元的产能方程,为水平井开发部署和产能预测提供了简捷有效的方法.

Horizontal wells are more and more valuable beginning from adopted to oil and gas development. In fact, horizontal wells are used as producers as more as possible in offshore fields. The case was studied when horizontal and vertical wells were simultaneously deployed as producers and injectors respectively. It assumed that a central vertical well was surrounded by several horizontal wells. The producibility equations of horizontal wells in areal well spacing were presented by the equivalent flowing resistance method. It was efficient to predict that how much output should be designed for the development units of horizontal wells.
