Abstract:
1. A high pressure oil pipe bullet plug for a high pressure oil pipe hole plugging apparatus that cuts through gushing oil and inflates with oil to facilitate a permanent plugging of an oil well pipe, comprising: a mechanical connection with a high pressure shipboard oil hose through a coupler to give an output port and nozzle a high pressure oil output to fight and lower the pressure of incoming oil gushing from well; a bladder in the static or reduced size state by a shipboard vacuum pump for inserting a plugging device into oil well riser, a bidirectional valve for switching to expand a bladder with the oil or liquids at a safe pounds per square inch (psi) to plug or shutoff the well from the gushing oil while oil stream from an output port and nozzle of the bullet plug continuing to fight the flow from the well; a mechanical coupler connection with a low pressure shipboard vacuum and oil hose for the bladder in the static state or reduced size by the shipboard vacuum pump during its insertion and descending of the plugging device into oil well riser then providing the same connection with the bidirectional valve for expansion of the bladder with oil at a safe amount of pounds per square inch (psi) to plug or shutoff the well from gushing while oil stream from the output port and nozzle continues fighting a flow from the well; a secure connection with the high pressure shipboard oil hose; a secure connection with the low pressure shipboard oil and vacuum pump; an oil well bypass with a bullet plug deflated and blocking or shutting off gushing oil well with bullet plug inflated tight by oil to the inside diameter of oil well pipe; a restraining bladder on one end and assisting with the maximum penetration an inside oil well pipe on other end with shape of nosecone and has a center opening for output port and nozzle attachment; a output port and settable spray pattern for shipboard oil that fights incoming gushing oil from well; a oil well bypass with the bladder deflated with the bladder inflated tight by oil to the inside diameter of oil well pipe shutting off gushing oil well bypass; a nosecone and bladder restraint secured from screw threads on output port pipe and a nut; a strut used by undersea robot for bullet-shaped plugging device installation into oil well and a pin with the bullet plug at the proper depth; a strut secured to riser pipe; an oil well pressure bypass around bullet shaped plugging device; a connection for a sensor on gushing oil well end of bullet-shaped plugging device; a hole for input port and vacuum pump port, and containing and securing a bladder at one end not to expand beyond a ports containment holder and bladder restraint thus concentrating the expansion to up against the inside of the oil well pipe as tight as possible; shipboard oil to fight the oil pressure from a deep water oil well; a cement mixture dispensed on top of bullet-shaped plugger to cure in smaller batches for maximum hardening while bullet plugger is expanded and blocking the oil from the gushing oil well; a high pressure shipboard oil pump that pumps recycled oil from the well back to the well based on affect of pressure from the oil well to instrumentation of pump two; a pumping of low pressure recycled oil into bladder to expand and plug gushing oil well maintaining oil pressure based on pump one instrumentation and with a bidirectional valve switched to pump one and not vacuum pump; a same oil from the well and oil pressure to the output port and nozzle of bullet-shaped plugging device to fight incoming oil from oil well; a vacuum from shipboard vacuum pump or recycled oil from shipboard oil pump to the bladder; a bladder is at its minimum size possible for insertion into oil well pipe; a valve turn on and cutoff of high pressure recycled oil from a shipboard pump two, rigidly connected for providing high pressure shipboard oil pump that pumps recycled oil from the well back to the well based on affect of pressure from the oil well to instrumentation of pump two; a valve turn on and turn off near a oil well riser for high pressure recycled oil from shipboard pump two, rigidly connected to said means for providing turn on and cutoff of high pressure recycled oil from shipboard pump two, and rigidly connected to said means for providing holes for input ports and vacuum pump port, and containing and securing a bladder at one end not to expand beyond the ports containment holder and bladder restraint thus concentrating the expansion to the sides up against the inside of the oil well pipe as tight as possible; a bidirectional switching from shipboard low pressure recycled oil to the bladder of the bullet plug or a vacuum to the bladder of the bullet plug, rigidly connected to the bladder to allow it to shrink to a minimum size possible for insertion into oil well pipe, and rigidly connected to a pumping of low pressure recycled oil into the bladder and plug gushing oil well maintaining oil pressure based on pump one instrumentation and with a bidirectional valve switched to pump one and not vacuum pump; a valve turn on and turn off near oil well riser for low pressure recycled oil from shipboard pump one or from shipboard vacuum pump, rigidly connected to bladder to shrink it to minimum size possible for insertion into oil well pipe, and rigidly connected to provide holes for input port and vacuum pump port, and containing and securing bladder at one end not to expand beyond the ports containment holder and bladder restraint thus concentrating the expansion to the sides up against the inside of the oil well pipe as tight as possible; recycled oil from well to the bullet plugging device and to the high pressure input port of the bullet plugging device for fighting the gushing oil from the well, rigidly connected to said means for pumping of low pressure recycled oil into bladder to plug gushing oil well maintaining oil pressure based on pump one instrumentation and with bidirectional valve switched to pump one and not vacuum pump, and rigidly connected to said means for providing high pressure shipboard oil pump that pumps recycled oil from the well back to the well based on affect of pressure from the oil well to the instrumentation of pump two; a strut to be mounted to ports containment holder and bladder restraint part; an opening for high pressure oil to fight oil gusher and preventing the bladder from closing off center hole of bullet plugging device, rigidly connected for providing holes for input port and vacuum pump port, and containing and securing bladder at one end not to expand beyond the ports containment holder and bladder restraint thus concentrating the expansion to the sides up against the inside of the oil well pipe as tight as possible, and rigidly connected for providing oil well bypass with bladder deflated and blocking or shutting off gushing oil well with bladder inflated tight by oil to the inside diameter of oil well pipe; an input output port pipe goes through center of bullet-shaped plugger; a shipboard low pressure oil or vacuum pump from input output hose two; a sealing of the oil well and supplemental to valve two near the top of the riser; and a cement mixture pumped into plugged oil well pipe in portions for maximum hardening, rigidly connected to said means for providing holes for input ports and vacuum pump port, and containing and securing bladder at one end not to expand beyond the ports containment holder and bladder restraint thus concentrating the expansion to the sides up against the inside of the oil well pipe as tight as possible.
