摘　　要：主要介绍了密度为1.65g/cm^3的全有机低固相抗高温完井液体系的组成、单剂筛选过程和配套处理剂配伍性的评价。确定了体系中高密度有机盐基础溶液的配比,即m(甲酸盐):m(有机复合盐):m(盐结晶抑制剂):m(水)为286:44:40:100,以及配套的处理剂——抗高温储层保护剂YH-YB01的筛选和评价,该体系适用范围广泛,是一种良好的抗高温、低固相、高密度完井液体系。The system composition of the fully organic and low solid content well completion fluid, which density is 1.65g/cm3 , was introduced. The compatibility of supporting treatment agent was evaluated, and sin- gle agent screening process was introduced. Meanwhile, it determines the ratio of the basic solution with high- density organic salts in this system m （formate and organic compound salt） ： m （salt crystallization inhibitors） ： m （water） 286 ： 44 ： 40 ： 100, as well as the screening and the evaluation of ancillary treatment agent- anti high temperature reservoir protective agent YH-YB01. The system is widely used in many scope of applica tion and is a good temperature resistance, low solid, high-density completion fluid system.
