wireline BOP

Introduction

A BOP (Blow out Preventer) is connected with the top of either wellhead adapter or wellhead. Annular space around wireline or slickline will be sealed by closing lubricator valve when the wireline or slickline is still in the hole. Then the pressure in the well will be sealed to prevent blowout. Single ram BOP is usually used for slickline and double ram BOP is for wireline accordingly. Three ram BOP (with shear ram) is also available. Max. work pressure is up to 105MPa (15,000PSI). BOP for standard and H2S services are both available with manual or hydraulic control methods.
