塔里木盆地哈得薄砂层油藏为双层、超深、超薄油藏,储量丰度特低,被评价为边际油藏。若采用常规方式开采,毫无经济效益,而利用双台水平井可大大增加泄油面积,可提高单井产量,实现“稀井高产”的开发效果。开发动态跟踪表明,双台阶水平井对全区稳定分布的深层双层层状边水油藏具有较好的适应性。

Tarim's HaDe thin-sand reservoir which is na med margin reservoir is a double-layer, super-deep, super-thin,particular-low-abundance reservoir. If we adopt normal methods to exploit, we  can not have any economic benefit, but if we adopt double-step horizontal wells , it can increase drainable area greatly,enhance individual well producing rate,  achieve the Tarim Oil fields exploiting rule of“wide spacing, high producti on”.According to the exploiting-dynamic-tracing research, double-step horiz ontal wells have good adaptability for the stable distributed deep zone double- layer banding margin reservoir of all the area, exploiting effect is very good,  economic benefit is obvious. According specialists appraise, the utilizing of  the double-step horizontal wells in exploiting Tarims HaDe thin-sand reservo ir attained the technique standard of “international leading, domestic classic ”.
