摘要
大牛地气田为典型低孔低渗砂岩气藏,不易形成自然产能,勘探开发中选择合适的钻井液体系保护储层显得格外重要,但目前该气田所使用的钻井液体系均没有取得令人满意的储层保护效果。近年来,针对低孔低渗砂岩储层保护的新型钻井液技术—Aphron钻井液技术得到了不断发展与完善,并在美国的Fusselman油田得到推广应用。本文据该钻井液技术的相关特性及大牛地气田储层特征分析,得出Aphron钻井液体系在大牛地气田具有相当广阔的应用前景。
DaNiuDi gas field is typical low permeability and pressure sandstone reservoir , it couldn't obtain nature productivity , so it is very important select suitable drilling fluid system in emploit process . But at present , the application of drilling fluids have been able to obtain little effect of reservoir protection In recent year , aphron- base drilling fluid have develop for protecting reservoir which is low permeability and pressure layer . The new type drilling fluid had been applied in Fusselman oil field , USA The paper analyses the reservoir characteristics of DaNiuDi gas field and the feature of drilling fluid technique , proves that aphron--base drilling fluid would have tremendous application prospect in DaNiuDi gas field.
