          摘要:
          為解決水平井電纜泵送橋塞與分簇射孔管串泵送不到位或為避免上傾井射孔出現工程復雜,需要將管串上提至直井段進行重復泵送,造成了作業時效低、成本高。提出了水平井段靜止起動泵送技術。詳細分析了水平井段靜止起動泵送過程并劃分了“靜止”、“起動加速”、“穩定運行”、“減速”等4個階段,結合力學分析建立了泵送推力、加速度、加速時間理論計算模型。試驗表明該套模型計算精度高,設計的靜止起動泵送階段排量、極限速度、加速時間等參數能指導現場作業,現場應用提高了作業時效、節約了成本。
          Abstract:
          In order to solve the failure of pumping plug and multi-cluster perforating joint operation in horizontal well or to avoid the perforating complexity in upturned well, for example, the pipe string needs to be lifted up to the straight well section for repeated pumping. Which results in low time effect and poor economic performance. For this reason, the pumping technology of static start-up in horizontal well section is put forward. The process of static start-up pumping in horizontal well section is analyzed in detail and divided into four stages: “static”, “start-up acceleration”, “uniform motion” and “deceleration”. In addition, combined with mechanical analysis, this paper establishes a theoretical calculation model for pumping thrust, acceleration and acceleration time. The test shows that the model has high calculation accuracy, and the parameters such as displacement, limit speed and acceleration time of the designed static start-up pumping stage can guide the on-site operation. When the method is applied in the field, the work time is saved and the cost is saved.
