全通径压裂滑套能实现整个压裂管柱的全通径，滑套的球座没有级差缩 径，整个压裂管柱使用同一种尺寸的压裂球来打开压裂滑套，实现压裂分段数 量不受限制。主要用于水平井裸眼分段压裂工艺，因其全通径特点，可实现无 限级压裂，并且能减少压裂摩阻，同时为后期的修井措施提供了便利性。

◎ 随压裂管柱下入，投球开启，操作方便； 

◎ 内部具有防砂卡结构，砂砾堆积不会对开启造成影响； 

◎ 具有相同的大内通径，不限级数； 

◎ 开启球尺寸相同，便于返排。

FULL BORE FRAC SLEEVE

The full bore fracturing sleeve can realize the full bore of the whole fracturing string, and the ball seat of  the sliding sleeve has no differential diameter reduction. The whole fracturing string uses the fracturing  ball of the same size to open the fracturing sleeve, so that the number of fracturing sections is not  limited. It is mainly used in the open hole staged fracturing process of horizontal wells. Due to its full  bore characteristics, it can realize infinite fracturing, reduce fracturing friction, and provide convenience  for later workover measures.

FEATURES

◎ With the fracturing string running in, the ball throwing is started, and the operation is convenient; 

◎ The interior has a structure to prevent sand from getting stuck, and the accumulation of gravel will  not affect the opening; 

◎ It has the same large inner diameter and unlimited series; 

◎ The opening ball has the same size for easy return and discharge.

Note: Other specification products are available.
