摘要:

在海上油田砾石充填作业中,由于设计、井眼不规则、地层等原因导致充填不完全或充填失败,严重影响油井产量。设计研发了一种新型多流道旁通筛管,在常规充填结束后,旁通通道继续对亏空段进行充填。通过自研的大型全尺寸水平井度砾石充填实验模拟系统,对所设计的多流道旁通筛管进行了性能评价。结果表明,在无砂桥旁通管砾石充填实验中,旁通段充填效率为100.0%,连接输送玻璃管时出口处返液流量与输送玻璃管返液流量比为0.68 1,相比清水实验,旁通通道内的液体流量大幅提高;与有砂桥旁通管砾石充填实验相比,常规筛管充填效率提高62.5%,出口处返液流量与输送玻璃管返液流量比为1.60 1。实验证明,新型筛管的旁通性能和输送性能良好,砾石充填效率高。

Abstract:

During gravel packing operations in offshore oilfields, incomplete packing or packing failure may occur due to design, irregular borehole, formation, and other reasons, which has a great impact on the production of oil wells. A new type of multi?channel bypass screen is designed and developed. After conventional packing is completed, the gap section continues to be packed through the bypass channel. The performance of the designed multi?channel bypass screen is evaluated with a self?developed large full?scale horizontal well gravel packing test simulation system, and the following conclusions were obtained through experiments. In the gravel packing experiment through the bypass pipe without a sand bridge, the packing efficiency of the bypass section measured is 100.0%. When the glass conveying pipe is connected, the ratio of the return flow rate at the outlet to that of the glass conveying pipe is 0.68 1. The liquid flow rate in the bypass channel is greatly improved compared to that in the unpacked clean water experiment.The packing efficiency of the gravel packing test through the bypass pipe with a sand bridge is 62.5% higher than that of the conventional screen. The ratio of the return flow rate at the outlet to that of the glass conveying pipe is 1.60 1.The experiments show that the new screen has favorable bypass performance and conveying performance and high gravel packing efficiency.

Key words: Multi channel bypass screen, Gravel packing, Gap section, Conveying capacity, Bypass performance
