Ram BOP has four sealing parts in order to shut off the wellhead effectively.The ram top seal and body seal; the ram front seal and pipe column, body andsealing between the pipe and the ram front seal; sealing between the body and theside door; sealing between the ram shaft and the side door. Procedure of the ramsealing divided into two steps: First the ram shaft affected by hydraulic oil pushesthe ram front seal rubber to press the front part of sealing distorted. Over

 Main pressure-bearing assemblies such as the body and the side door are cast with alloy steel of high strength and high toughness and properly heat treated before leaving the factory, the BOP is water pressure tested to ensure safety during operating under working pressure. There are high supporting ribs and obligue plane for settling sand sloping to the well hole at the bottom of the ram cavity of the body, desanding autoly when opening and closing the ram, reducing friction of the ram. It is also helpful for well pressure assisting ram seal. Using floating ram sealing can reduce the resistance force of opening and closing the ram, wearing of the ram rubbers, prolonging the ram life and also preventing rustiness between the body and the ram, accessible for changing. Hydraulic pipe is used with buried structure to avoid damaging the pipe during installation, transporting and operating. Size of outer coupling conforms to API 16A specification.

13 5/8”-10000psi Shear ram can cut pipe in the well and completely shuts off thewell. And It can also be used as normal C.S.O. ram. Shear ram can be installedin the normal BOP.

Shear ram can be used to seal working pressure to Max. 10000psi.4.3.3 Caution to use shear ram ▲ ！The shear ram cannot resist H2S. If work in H2S environment, must be careful； ▲ ! Inspect BOP in time after cutting drill pipe, including seals on the ram inspection, fluid penetration inspection for shear blade and ram being squeezed or not to affect open & close performance. Seal tests must be done before this shear ram being used next time. ▲ ! To avoid cut tool joint on drill pipe during cutting drill pipe.

seam so as to achieve the seal remedy.Caution to use secondary seal system:To prevent the grease from being solidified after long time, we do not put grease inBOP in factory. And while the BOP is not used, it is also without this grease. Onlybefore the BOP is used in site, put in the grease. And after a well is completed andthe BOP is inspected and repaired, take out and clean the grease.Get special tool ready.During working should often notice the following notice hole plug (on it there is littlehole) if there is liquid flowing out.Don’t inject too much grease when seal ring is damaged. Proper inject quantity isthat there is no liquid flowing out. Because the secondary seal grease is morefrictional and with granule substance, it impairs the ram shaft when it returns.

The ram lock assembly of this type of BOP is manual-lock. Manual lock systemcloses and locks the ram by the manual wheel. It consists of locking shaft, ramshaft, manual operating rod and hand wheel, etc.. Its application is to seal the wellfor a long time, lock the rams in closing position after close the rams with hydraulic

Read this section first before BOP installation. Structure, function and caution havebeen introduced in above-mentioned chapters and this section for installation andoperation.

6.1 Preparing works before installation (1) Check weather gaskets of wellhead flange and BOP flange is well or not andsurface of wellhead flange. Protruding is not allowed to exist. (2) Check installed ram rubber sizes to see if it is compliance with drilling toolsizes. (3) Check weather pressure tests are qualified or not.

operation, to ensure its proper operation.1) Check BOP is installed rightly or not: lifting ring of body should be installed on the upside; manual locking device should be installed completely and well fastened, and hang a plate where the hand wheel is to indicate the open and close circles; everywhere the connecting bolt diagonal should be in turn tightened equably.2) Inspect oil pipes to see if they are in compliance with BOP switch direction, provide 286~429psi control pressure to test each ram twice (open and close), draining air from the pipes. If ram switch movement is not the same direction as the mark on the hand rod of control platform, reverse the connection pipes.3) Inspect manual-lock system to see if it is well connected, and if closing and opening with the hand rod is fixable or not record hand wheel circle number when closing well and mark it on hand-wheel. After finishing the tests, rotate hand wheel left and make it unlocked, open ram with hydraulic pressure.4) Wellhead equipments shall be pressure tested fully. Standards of test shall be according to related well control specifications. After tests, every connection bolt is fixed once again avoiding unbalanced distribution. See the tightening torque of flange bolt from list 15 or 16.

BOP operation must be charged by specialist and professional person. Operators shall be familiar with BOP working principle, specifications and process, and can also operate, repair, maintain and clear troubles. 1) When testing without string in hole, the max close pressure does not exceed 429psi to prevent rubber from damage. When there is string in the well pressure prohibit closing the blind ram. 2) Closing well for a long time, lock ram with locking system hand-control locking situations shall be marked on control platform to prevent wrong operation. 3) After reaching objective interval, the rams should be opened and closed one time every day to see if they are flexible lock in normal condition. After the drill string is pulled out of the well, blind ram open and close test is needed. When there is string in hole, do not close blind ram.

B. Put drill pipe inside BOP and make sure it connected with test platform reliableduring testing pipe ram to avoid being squeezed out from BOP. There is no drillpipe inside BOP during CSO & shear rams.

A. Install BOP on the test platform and connect open & closed hydraulic hoses withBOP. Connect lines from high-pressure tester to test platform or BOP outlets.

C. Lift a drill pipe G-105 4ft long on the right top of BOP and put inside wellhead.Buttress the drill pipe loosely under ram to avoid overly bending and cutting tooljoint during cutting drill pipe.

Not install ram or put bonnet on open position. Caution: Not to extend ram shaftcontacting body and fix BOP on the ground to avoid leaning as result of center ofgravity excursion due to two side outlets open at same time.

 Prohibit releasing pressure by opening ram to prevent rubber from damage. Before opening ram, check if the manual-lock system kept in unlocking position each time. And after that, check if the ram remaining fully opened to prevent ram from drilling tool bumping.  Keep hydraulic oil clean.  After usage of BOP ram opened fully for easy repair.  Discharge water from BOP after pressure test and before storage. Put ram in full open position and do rust-resisting treatment.

BOP shall be cleared completely after every testing at site. Replace damaged partsin time, anoint so as to prevent rust after cleaned ram chamber and ram of body,(suggest to oil them by synthetic complex aluminium grease), and oil connectingthread part by thread grease.

7.1 REPLACEMENT OF RAM AND RAM RUBBER Ram rubber is the key part in a BOP. If damaged, BOP is useless in sealingwell. So it is very important to keep it well, and replace it in time if there is damagein sealing surface. Procedures of ram rubber replacement:▲！Note: manual locking device should be unlocked. 1) Open the ram completely with hydraulic oil. 2) Remove bolts that retain the bonnet. Open bonnet and flatly pull ram assembly out of the ram shaft tail. While taking out ram assembly, note to protect the bonnet seal surface, ram and ram shaft from being knocked and scratched. 3) While replacing ram rubber, first upwards prize top seal, then forward dismount face seal, last replace new rubber. Assembling order is contrary to disassembling.
