摘　　要：方法　依据曙一区超稠油蒸汽吞吐特征 ,选用高温产液剖面测试仪 ,对放喷期产液剖面进行测试。目的　分析超稠油蒸汽吞吐开发油层纵向动用状况。结果　仪器耐温 35 0℃ ,耐压 2 0 MPa。杜 32块放喷期测产液剖面主力产液层占 45 % ,纵向动用程度 6 7.7% ;低产层投产初期弱吸汽不产油 ,油层纵向产液能力与渗透能力具有显著的一致性变化规律。结论　仪器耐高温、高压稳定性能好 ,分辨率高 ,可实现超稠油蒸汽吞吐高温环境下的产液剖面测试。其测试结果可作为分层注汽、调剖等措施的参考依据。Method From steam soaking characteristics of super heavy oil in Shu 1 area, fluid producing profiles during flowing is tested with high temperature profile tester. Purpose To analyze vertical Pro-ducing thickness over the overall layer (POR) in developing super heavy oil with steam soaking. Result This tester can resist 350 'C and 20 MPa. Main fluid producing interval takes up 45% of the whole profile in flowing and 67. 7% POR. I.ow productivity layer absorbs little steam but produces no oil during initial production period. The vertical fluid producing capability of oil bearing formation varies obviously and consistently with permeability. Conclusion Fluid producing profile testing under harsh conditions of super heavy oil steam soaking can be accomplished with this tester since it resists HTHP and possesses stable performance and high resolution.
