API 16A Shaffer NL Oilfield BOP Manual and Hydraulic

Product Introduction

Hydraulic ram BOP is the important component of well drillig control equipment. It has the features: rapid open, labor-saving operation, easy maintenance, use for safe and so on. Ram BOP is mainly composed of housing, side gate, hydro-cylinder, cylinder cap, piston, piston rod, lock shaft, sealing parts, ram, etc. Oil well's sealing or opening is achieved by moving ram, which is driven by piston rod and piston with hydraulic force.

According to the different opening and closing method of bonnet, ram BOP can be divided into two forms: Rotating bonnet ram BOP and linear bonnet ram BOP. For the rotating bonnet ram BOP, when opening or closing bonnet, the bonnet rotates on the hinge sear fastened on the body, the ram cam cavity shape of such BOP is rectangle.

Operating requirements of TR Drilling BOP:

• It's feasible to control wellhead with annular preventer firstly when blowout occurs in a well where there are drilling tools, but try not to seal it for long, because rubber core is fragile and there is no locking device. Don't close empty well with it in non-special cases.
• It's necessary to use a drilling tool with an 18-degree slope when annular preventer is used for snubbing tripping operation. Tripping speed should be slow when passing through joints, and all the rubber sleeves of the drilling tool should be uninstalled.
• When annular preventer is in an off state and shut-in pressure is below 5Mpa, it's feasible to move the drilling tool up and down, but don't rotate it.
• It's necessary to check whether the well is opened completely after it is opened every time lest rubber core be scraped.
• It's necessary to wash the inner cavity out to keep the switch flexible after well cementation and leaking stoppage, etc.
• Be sure to pay special attention to sealing backing ring and steel ring groove when installing or uninstalling annular preventer, which cannot be cracked up or scratched.
• After entering the target layer, try to shut in the well with drilling tool after tripping each time, to check how well the rubber core seal the well. It should be replaced at once if not up to standard.
• Make regular pressure test on the annular preventer according to relevant standards.
