建南某气井井口压力恢复“尖峰”式波动情况分析

建南某气井在进行压力恢复试井时,井口压力恢复速度缓慢且压力呈现阶段“尖峰”式上升。经分析,压力恢复缓慢的原因主要受邻井生产干扰及自身能量低影响;压力呈现阶段“尖峰”式上升主要受环境温度的变化、压力计精度高、灵敏度强影响,并且根据压力波动标准,判断该井压力波动属正常范围。该结果为气井压力恢复缓慢及异常提供了分析思路,为压力恢复是否达到标准要求提供了依据,具有一定的参考价值。

Fluidization Characteristics of Silicon Particles with a Wide Size Distribution

Fluidization characteristics of silicon particle system are studied by the pressure fluctuation method.The existence of fine particles in the system can improve fluidization. Silicon particles with a wide size distribution,preferably with some fines, behave as Group A particles according to Geldart classification, although the system belongs to Group B actually. The system is also approved to be suitable for organochlorosilane monomer production using a fluidized bed reactor. Experimental data obtained in this work are important for the design and operation of commercial fluidized bed reactors for the production of organochlorosilane monomers.
