-
摘要: 为降低钻井过程中的储层损害,解决微泡沫钻井液抗温抗盐性能不足、稳泡效果差的问题,合成了微泡沫发泡剂LF-2和稳泡剂HMC-1,优选了增黏剂和降滤失剂,配制了抗温抗盐无固相微泡沫钻井液。室内性能评价表明,该钻井液的岩屑回收率达88.7%,40/80目砂石漏层中30 min漏失量仅1.8 mL,岩心渗透率恢复率88.87%。抗温抗盐无固相微泡沫钻井液在茨120井欠平衡井段的应用结果表明,其性能稳定易调整,平均机械钻速达4.41 m/h,平均井径扩大率仅为3.97%,欠平衡钻进效果明显,全烃值最高100%,并多次点火成功。研究表明,抗温抗盐无固相微泡沫钻井液体系抗温、抗盐能力强,储层保护效果好,具有推广应用价值。Abstract: In order to reduce reservoir damage during drilling and to improve temperature resistance, salt tolerance and foam stabilization of micro-foam drilling fluid, a new type of solid-free micro-foam system with temperature resistance and salt tolerance was prepared by synthesizing the foaming agents LF-2 and foam stabilizer HMC-1 and optimizing viscosity increasing agents and fluid loss additives. Laboratory performance evaluations showed that the cutting recovery rate was 88.7%, the recovery rate of core permeability was 88.87% and the circulation lost was only 1.8 mL in 40/80 mesh sand thief zones within 30 min. Later, the new system was used in underbalanced intervals drilling of Well Ci120. Results indicated that this new system was stable and adjustable, and drilling improvements were remarkable with average ROP 4.41 m/h and average hole enlargement rate 3.97%, respectively. In addition, the maximum total hydrocarbon of the intervals was up to 100% with success ignitions. In summary, the solid-free micro-foam drilling fluid system is strong in terms of temperature and salt resistance, and it demonstrates good performance in reservoir protection is worthy of further large scale application.
