摘要:
为优选连续油管冲砂排量，以单个砂粒在冲砂液中的受力分析为基础，建立了砂粒沉降速度计算模型；对沉降速度中关键参数进行拟合，获取了沉降速度计算公式；研究连续油管冲砂排量的计算方法，获得了不同套（油）管、不同连续油管工况下最低排量的优选模板。大港油田官882井和官1801井的冲砂施工过程中，依据优选模板，选择合适的冲砂排量，使连续油管冲砂较常规修井作业提高工作效率24倍。连续油管冲砂排量的优选可为合适冲砂排量的选择提供理论支撑，保证冲砂施工高效、经济地进行，为连续油管冲砂方案的制定提供理论指导。
Abstract:
The sand settling velocity model was established after analyzing the force imposing on single sand particles in sand flushing fluid. Then key parameters related to the settling velocity were fitted to obtain a formula for calculating the settling velocity. And finally the optimal templates of the minimum sand flushing displacement under various casing (tubing) and coiled tubing working conditions were established. For Wells G882 and G1801 in Dagang Oilfield, the sand flushing displacement was estimated using the templates, as a result the coiled tubing sand flushing operation was more effective than a conventional workover by increasing 24 times. These templates provide theoretical support for determining appropriate sand flushing displacement. They can ensure efficient and economical sand flushing operation and are theoretical bases for designing coiled tubing sand flushing plan.
