Rotary Casing Guide Shoe

Introduction

Rotatory casing guide shoe is effective in reducing running casing friction, borehole irregularity and horizontal section desilting problem. Special anti-drop design ensures roller not broken off from the body. The rotatory casing guide shoe was applied successfully in many oil and gas wells including the most critical shale has wells in Sichuan and Chongqing area China.

Rotatory casing guide shoe converts fluid flow energy into rotating power through self-rotating components, making shoe head rotational, that would help running casing and recondition the borehole wall efficiency.

Function & Working Principle

Features and Advantages

-      The design for rotation of the head makes the direction can be changed automatically when casing meets obstacles.

-      The head can rotate itself or using the fluid to drive it rotate when pumping.

-      Because of taking the design of fluid driving, it can circulate the fluid to drive the head rotated and scrape the cake, silt deposit and make the casing unrestricted.

-      Suit for vertical well, directional well, highly deviated well and horizontal well.

-      Wide flow area satisfies the requirement of cementing.

-      The material of the shoe is 40CrMnMo which has good mechanical property, meeting the requirement of impact resistance when casing.

-      Wheels are inserted on the shoe, greatly reducing the resistance when casing. And the head can finish the wall when passing the well.
