  • A thixotropic expandable high strength water shutoff agent and a technology of staged injection of the shutoff agent have been developed to satisfy the needs of water shutoff operation in horizontal wells. Laboratory evaluation showed that the water shutoff agent had good thixotropy and yield point of 10-15 kPa. It was suitable for use at temperatures between 30℃ and 120℃. The compressive strength of the water shutoff agent was greater than 13 MPa, and the thickening time was longer than 6 h. The volume of the water shutoff agent after solidification expanded by 1.0%-1.5%. As a high strength water shutoff agent, it increases the efficiency of water shutoff, prolongs the life of water shutoff, and overcomes the problems often encountered in horizontal section such as the mixing of cement water shutoff agent and kill mud, and poor application safety of other water shutoff agents commonly available. A self-degradable sol was developed to protect the water shutoff agent plug from being mixed with kill mud during injection. Tools for staged injection of water shutoff agent were selected for the staged shutoff of the water producing sections. This technology has been successfully applied on 5 wells in Dagang Oilfield and Qinghai Oilfield, with oil and gas production increased by 5 849 t and 1.4 ×104 m3 in total, respectively, demonstrating the reliability and long-term safety of the technology.
