摘　　要：为了满足复杂地层高温条件下的钻井需求,需对现有的钻井液体系进行配方优化,以满足实际施工要求。本文对施工现场的HEM抗高温钻井液体系进行了性能测试,然后针对性地进行处理剂选择与加量优化,由此形成适用于现场工况的钻井液体系配方。原体系在150℃高温条件下不满足现场施工要求,经本文实验优化后,形成的HEM抗高温钻井液性能满足需求。优化后钻井液体系配方为:3%海水土浆+0.25%Na_(2)CO_(3)+0.15%NaOH+1.5%LSF+1.5%LPFH+2%UHIB+3%SMP+3%SPNH+1.4%FLOTROL+0.6%UCAP+0.3%XC+2%HLUB+0.8%HTFL+8%NaCl+6%KCl。In order to meet the drilling requirements under high-temperature conditions in complex formations,it is necessary to optimize the formulation of the existing drilling fluid system to meet the actual construction requirements.In this paper,the performance test of the HEM anti-high temperature drilling fluid system at the construction site was carried out,and then the selection of treatment agent and dosage optimization were carried out in a targeted manner,so as to form a drilling fluid system formula suitable for the on-site working conditions.The original system does not meet the requirements of on-site construction at a high temperature of 150℃.After optimization in this paper,the performance of HEM anti-high temperature drilling fluid can meet the requirements.The optimized drilling fluid system formula is:3%seawater mud+0.25%Na_(2)CO_(3)+0.15%NaOH+1.5%LSF+1.5%LPFH+2%UHIB+3%SMP+3%SPNH+1.4%FLOTROL+0.6%UCAP+0.3%XC+2%HLUB+0.8%HTFL+8%NaCl+6%KCl.
