随着油田开发的深入,油水井套损问题已经成为油田开发过程中急需解决的问题。固井质量差,会导致注入水窜入泥岩,造成泥岩的膨胀,使套管受岩层作用力挤压产生套损。本文主要对固井质量差引发套损的原因进行分析,采取相应措施,提高固井质量,从而有效地减少油水井套损。 With the deepening of oilfield development, the problem of casing damage in oil and water wells has become an urgent problem to be solved in the process of oilfield development. Poor cementing results in the infiltration of water into the mudstone, resulting in the expansion of the mudstone, causing the casing to be crushed by the force of the rock formation. In this paper, we analyze the causes of casing damage caused by poor cementing quality, and take corresponding measures to improve the cementing quality so as to effectively reduce casing damage.
