摘要
针对雄安新区基岩热储钻探中风化壳钻进、地层大量漏失封堵及基岩取心的钻探工程难点,通过对所处牛驼镇地热田、容城地热田和高阳地热田地热地质状况、岩性特点的分析,提出了基岩热储地热钻探有效解决方案,包括采用小径探孔施工工法、采用封隔器有效完成水泥浆堵漏、借鉴金刚石满眼取心钻具技术等.
Abstract
Aiming at the difficulties exist in thermal reservoir drilling in bedrock of Xiong'an New Area such as drilling in weathered crust,plugging severe formation lost and coring at bedrock,an effective solution for drilling in bedrock thermal reservoir is proposed including small diameter exploration wells,effectively mud plugging using packers and borrowed the principle of diamond full hole coring tool technology through the analysis of the geothermal geological conditions and lithological characteristics of Niutuozhen Geothermal Field,Rongcheng Geothermal Field and Gaoyang Geothermal Field.
