摘要
针对苏里格气田苏11区块地层特点和钻井施工要求,以苏11-25-56直井为落脚点,对该区块的直井分段钻井液技术进行剖析。该钻井液技术对各井段易出现的井下复杂情况分段进行解决,并指出了各井段钻井液的配置与维护方法。分段钻井液技术对井下复杂情况起到了很好的预防作用,同时保证了高效的钻进速度和降低了钻井液对气藏的伤害。
Based on the stratigraphic information characteristics and drilling construction requirements of Su 11 block of Sulige gas field, the paper analyzed the sublevel drilling fluid method of this area by taking Su 11-25-56 for instance. Sublevel drilling system deal complicated hole conditions with section technology, and also told how to make and maintain it, which have a favorable effect for complicated hole conditions, as well as guaranteed drilling rate and reduced the damage to reservoirs.
