摘要
苏里格气田是典型的低渗、低压、低丰度岩性气藏,单井产量低,建井数量多,直井开发经济效益较差。为进一步提高开发效益,长庆油田转换开发方式,开展"三低"气田水平井开发技术攻关。2008-2009年,苏里格气田加大水平井开发试验力度,完钻10口水平井,投产8口,初步形成了水平井井位优选和随钻地质导向、钻井提速及储层改造等技术,取得了显著的效果为苏里格气田水平井规模开发提供了有利的借鉴和指导作用。
The Sulige gas field is belong to low permeability,low pressure and low abundance lithologic gas reservoir that has many wells and low well yield.Due to the inefficient vertical well development,the Changqing oil field company conversed development model to improve the effectiveness.From 2008 to 2009,the company carried a series of technology researches and tests that had drilled 10 horizontal wells in which 8 wells had produced.So it had formed a horizontal well location optimization and orientation while drilling,reservoir stimulation techniques and so on.These significant results provided a favorable reference and guidance for the horizontal scale in Sulige gas field.
