水力锚是在井下指定位置用来对封隔器进行锚定的工具。由于常规水力锚结构设计的缺陷，井下液体杂质（地层砂、支撑剂）容易进入到锚爪内腔并在此沉积，导致锚爪解卡受阻，严重影响封隔器的封隔效果。提出了利用卷吸效应在水力锚内部形成高速射流，以此来控制液体杂质的运动轨迹，将进入到锚爪内腔的液体杂质在压力差的作用下从内腔中卷吸出来，同时防止外部杂质再次进入到锚爪内腔中。利用伯努利方程对此原理的可行性进行了分析。

Hydraulic anchor is a mechanism that packing packer in pre-assigned position of a well. Cruds (formation chunk & proppant)depositing in inner chamber of anchor in the bottom of the well have a bad impact on anchor’s releasing and packer’s performance.This paper introduce an i-deal to control cruds moving track which make use of the entrainment phenomenon to develop a high-speed jet in inner chamber so that cruds can be entrained form inner chamber while prevent cruds outside deposited in it again.Bernoulli's equation is also used to prove the ideal’s feasibility.
