水平裸眼井砾石充填防砂提前脱砂原因分析

Cause Analysis of Early Desanding of Gravel Filling in Horizontal Open-hole Well

在渤海油田某井进行水平裸眼井砾石充填过程中,相关作业参数严格按照施工前的模拟设计进行,但仍发生了提前脱砂的情况。本文对脱砂原因进行了分析,并对后续作业提出了建议。

In the gravel packing process of a horizontal open hole well in Bohai Oilfield,the relevant operation parameters are strictly in accordance with the pre-construction simulation design,but the sand out still occurs in advance.This paper analyzes the reasons for sand out and puts forward some suggestions for subsequent operations.
