水平井酸洗堵漏一体化完井技术在胜利油田得到了广泛的推广应用。现河采油厂王家港油田王73区块为强酸敏和极强水敏储层,在酸洗清除泥饼时如采用常规酸液容易对地层造成二次伤害,针对这个问题我们研制出适应王73块储层特征且能高效清除钻井时泥浆污染的复合解堵体系。该体系既能满足预防水敏的需要,同时也要满足防酸敏的需要,能够满足解除泥浆及其滤液对地层造成的伤害的需求。 Horizontal well pickling plugging integrated well completion technology in Shengli Oilfield has been widely promoted. Wang River oil production plant Wangjiagang block Wang 73 block for the strong acid-sensitive and highly water-sensitive reservoir, remove the mud cake in the pickle if the use of conventional acid easily cause secondary damage to the formation, in response to this problem we developed to adapt to Wang 73 Block reservoir characteristics and can effectively remove mud pollution during drilling complex plugging system. The system can not only meet the need of preventing water sensitivity, but also meet the need of anti-acid sensitivity, which can meet the demand of relieving the formation damage caused by the mud and its filtrate.
