SLIDING SLEEVE

INTRODUCTION

Sliding Sleeve is a fluid control tool. The switch function can be controlled by slickline operation. Therefore, the payzones are communicated. Sliding sleeve can be in the state of full opening, equilibration or closing by three- position elastomeric clip lock groove. When sliding sleeve switch is in the state of full opening or full closing, the differential pressure between tubing and tubing and casing annulus can be balanced through the equilibrium orifice of inner sliding sleeve. It can be selectively switched for certain sliding sleeve depending on requirements.

The collapse strength, tensile strength and burst strength of circulation sleeve are equal to or greater than that of N80 tubing. Some model sliding sleeve is also available, which strength is equal to or greater than that of P110 tubing.

FEATURES

◎ Non-elastomeric seals;

◎ High polished seal surface;

◎ The flowing area of circulation sleeve / production is the same as that of tubing section.

◎ Circulation sleeve is in the state of stillness seal after opening / closing switch;

◎ Three-position elastomeric clip lock groove;

◎ High differential pressure can be balanced through the equilibration orifice of inner sleeve
