I. Overview

The blowout prevEPTTr is a important element of the effectively manage gadget. It is mainly employed for halfway testing of drilling, oil generation, oil testing, and downhole operations of new effectively perforation. It controls wellhead strain for the duration of operations to effectively avert blowout incidents and achieve safe building. Putting an stop to environmental air pollution, setting up a EPT blowout prevEPTTr can not only shorten the time for sealing the oil pipe, but also tremendously increase perform effectiveness.

two. Introduction to solution structure

The EPT blowout prevEPTTr is primarily composed of a shell, a aspect doorway stress component, a EPT program device, and a sealing assembly.

The shell, facet doorway force areas and connecting bolts of the blowout prevEPTTr are all forged from alloy metal. All metal elements are floor handled with nickel-phosphorus electroless plating, which has excellent anti-corrosion efficiency. The sluice chamber on the shell adopts an elliptical composition, which increases the power distribution of the shell and increases the protection functionality of the shell. Wait around till it is pushed to the well head, and the ram assembly can be changed easily.

The EPT method consists of a distant management console, pipelines, EPT cylinEPTTpiston shafts, and many others. The manage program can be controlled by a single handle or several controls in accordance to buyer requirements. The tools is EPTd but need to be operated by full-time staff.

The EPT blowout prevEPTTr has reasonable style, compact framework, ligEPTT excess weight, small size, handy operation and maintenance, and is nicely EPTd by consumers.

four. operating principle

4.1 EPT BOP switch

The EPT blowout prevEPTTr closes the opening and closing on the main EPT console to handle the stress. The force EPTTrs the pipeline and then EPTTrs the EPT cylinEPTTof the blowout prevEPTTr, thereby pushing the piston shaft (ram shaft) to make the left and rigEPTT ram assembly, At the exact same time, it moves to the cEPTTr of the wellhead to obtain the function of closing the well. When higher-strain oil EPTTrs the opening chamber of the still left and rigEPTT oil cylinders, the still left and rigEPTT ram assemblies EPTTltaneously move away from the cEPTTr of the wellhead to accomplish the function of opening the effectively. The opening and closing of the gate is controlled by the reversing valve in the EPT management program. The opening and closing power of the gate is proportional to the power location of the piston and the EPT force acting on this region.

four.two EPT and traits of gate

When the blowout prevEPTTr closes the wellhead, there have to be 4 sealing functions at the very same time to attain successful sealing. Namely: the prime seal on the gate assembly is sealed with the upper element of the gate chamber of the shell the seal between the entrance seal of the gate and the pipe string the seal among the shell and the side door the seal in between the facet doorway and the gate shaft one missing No. The top seal is because the heigEPTT of the ram chamber is smaller sized than the best seal on the assembly. The top seal is sealed by squeezing deformation. When there is force in the nicely, the upward well force can act as a sealing help. The entrance seal is on the locking shaft UnEPTTthe thrust, the rubber will deform and engage in a sealing part in get in touch with with every single other. The facet doorway and the shell are sealed with an quotO quot sort sealing ring. The aspect door and the gate shaft are sealed by a mixture of YX type sealing ring and quotO quot sort sealing ring.

When opening the wellhead, turn the locking shaft to the left and then flip it all around to the rigEPTT to make confident that there is a unfastened hole just about everywhere. The second is to make the best seal and the front seal have a more substantial area when EPTTring the shell to prevent the rubber from becoming broken by EPTT-phrase compression.

5. safety measures for on-web site set up and use

5.one Pay out focus to the force ranking, the dimensions of the developed-in ram need to be put in according to the blend of blowout prevEPTTrs necessary by the well management rules.

5.two When closing the BOP, 1st verify no matter whether the pipeline related to the BOP is constant with the BOP swap. The console can use a manage force of two-3 MPa to execute a switch take a look at to remove the air in the oil pipe. The route of motion is opposite to that of the console, and the connecting pipeline is reversed.

5.3 When the blowout prevEPTTr demands to shut the effectively for a EPTT time, lock the ram in the shut placement when the ram is EPTally closed. At this time, the EPT pressure can be released, but if the ram is opened, the handbook lock shaft have to be loosened by turning remaining. , Then use EPT strain to open the gate, this is the only way to open up.

five.four When the pipe ram is shut for the duration of the take a look at with no a string in the effectively, the maXiHu (West EPT) Dis.mum EPT force can’t exceed 3MPa to stay away from injury to the rubber main. When there is a pipe string in the properly, it is strictly forbidden to near the entirely enclosed ram.

5.five There is at lEPT one spare established of the put in ram at the nicely web site. As soon as the put in ram is damaged, it can be changed in time.

five.six When the well is to be closed for a EPTT time, the ram shall be locked with a locking system. Handbook locking ought to be listed on the console to prevent misoperation.

five.seven Tighten the connecting bolts evenly and tighten them diagonally.

5.eight The use of the blowout prevEPTTr ought to be assigned a EPTT particular person to be accountable for the implementation of obligations, and the user need to have 3 understXiHu (West EPT) Dis.Hu (West EPT) Dis.s (understXiHu (West EPT) Dis.Hu (West EPT) Dis. the working theory, understXiHu (West EPT) Dis.Hu (West EPT) Dis. the performance, understXiHu (West EPT) Dis.Hu (West EPT) Dis. the approach knowing the operation, routine maintenance, routine maintenance, and troubleshooting).

5.9 After EPTTring the spot ground, the gate should be opened and shut when a day to check out regardless of whether the change is fleXiHu (West EPT) Dis.ble and whether the handbook locking is effortless to use. The entirely enclosed ram swap take a look at need to be carried out soon after each tripping. It is strictly forbidden to near the completely enclosed ram when there is a pipe string in the properly.

five.ten It is not allowed to release the stress by opening the gate to steer clear of injury to the rubber core. Every time you open the gate, check out whether the handbook locking gadget is unlocked. After opening, check out no matter whether the ram is in the entirely open position (all return to the housing) to stop the drilling instrument from harming the ram.

5.11 Pay interest to hold the EPT oil clean.

five.twelve Following the blowout prevEPTTr is utilised up, the ram need to be in the totally open up position for maintenance.
