What is the bridge plug?
The bridge plug is a tool used in applications in fluctuations in the oil drilling industry. Downhole means that the bridge plug is used in a subsurface manner, which means it is applied to Wellbor or underground to prevent the use of a well. The Bridge Plug has permanent and temporary applications, which means that it can be applied in a way that permanently ceases to produce oil that occurs from the well to which it is applied or can be produced in a way that makes it beneficial from the well, allowing production from the well to restore. They can also be temporarily used in the wellBort to prevent oil oil from reaching the top zone of the well while it is located or treated.
Bridge plugs are usually made of a number of materials, each with its own appropriate advantages and disadvantages. For example, bridge plugs made of composite materials are often used in high-pressure applications because they are capable of withstand pressures 18 000-20 000 PSI (124-137 MPa). On the other hand, their lasting use tends to slip over time due to lack of connection between composite materials and materials inside the well. Bridge plugs made of cast iron or other metal can be ideal for long -term or even permanent applications, but in high -pressure situations they are not very well followed.
The bridge plugs are not only placed in Wellbor and allow the end to be attached. In fact, the location of the bridge plug in Wellbor is either permanently or temporarily stopping the flow of oil or gas is an intense process that must be carried out tactically and skillfully. It must be made when using the tool for the bridge plug, which is specially designed for the effective placement of the bridge plugs.
The tool used to place the plug usually has a tapering and threaded Mandrelded in the center of the bridge plug and has compression sleeves placed behind each other so that the tool is plugged into the plug, rThey compress the plug around the plug and rotate the tool through the plug into the well. When the bridge plug is at the desired depth, the tool is released from the axial center of the plug and from the cylinder without a flow. The instrument is removed from the wellBore with leaving the plug in place, because the sleeves have been decompressed as soon as the tool is no longer connected.
