摘　　要：以HB气田典型井XX03井为研究对象,通过对堵塞物类型、堵塞位置、解堵药剂及合理配产的研究,认为XX03井为多堵塞物、多井段的复合堵塞,并形成了“放喷解堵+工作液配合连油通井”的两步走单井复合堵塞井筒解堵措施及“临界携液、低产控固”的合理生产制度,成功解除XX03井复合堵塞,为同类型井的解堵措施及生产优化提供了经验和借鉴。This paper takes the typical well XX03 of HB gas field as the research object,and studies blockage types,plugging locations,plugging agents and reasonable production allocation.It is concluded that well XX03 is a compound blockage with multiple blockages and multiple well segments.And blowing out the plug and using coiled tubing through the well with working fluid of single-well compound plugging measures and critical yield carrying liquid or low yield controlling solid impurities of production system are formed,which successfully apply to the compound plugging of well XX03.Above methods provide experience and reference for the plugging removal measures and production optimization of the same type of Wells.
