稠油开采防砂技术及相关影响因素

Sand Control Technology and Related Influencing Factors in Heavy Oil Recovery

防砂是油藏开发过程中极为关键的工作内容之一,出砂问题将对油管、深井泵等相关设备造成严重磨损,极大地增加不必要的维修工作量,出砂严重时甚至可能造成油层坍塌和油井报废,进而在很大程度上增加生产成本,提升后续开采难度。为了提高油井周期产油、延长周期寿命,稠油开发单位以及工作人员需要根据出砂情况确定防砂类型和具体措施,探究有效防砂技术及方法成为相关工作者亟待解决的问题之一。本文从稠油开采防砂技术入手,探究稠油开采防砂相关影响因素,以期为提升防砂效果以及开采有效性提供资料参考。

Sand control is one of the most critical tasks in the development of reservoirs.The problem of sand production will cause serious wear and tear on related equipment and greatly increase the maintenance workload.If the sand production is severe,it may cause the oil layer to collapse and the oil well to be scrapped,which will greatly increase production costs and increase the difficulty of subsequent mining.In order to increase the production cycle of oil wells and extend the life of oil wells,relevant units and staff need to determine sand control types and specific measures based on sand production conditions,and explore effective sand control technologies and methods Become one of the urgent problems for related workers.This article starts with the sand control technology of heavy oil exploitation,then explores the relevant influencing factors,and hopes to provide a reference for improving the sand control effect and exploitation effectiveness.
