Description

[Detailed description of the invention] Diversion equipment TECHNICAL FIELD This invention relates generally to oil well flow diverters and systems, and more particularly to wellbore flow diverters and systems. body, i.e., the drilling mud and the floor of the rig where the well pressure is uneven during the first hole. A device that redirects the flow of chips that would otherwise be blown upwards. Regarding the system. In general, devices and systems according to the present invention may be used on any The present invention has particular application in floating drilling equipment.

When drilling an oil or gas well, a large diameter hole is first drilled to a shallow depth. Ru. A protective implant conduit or guiding path typically 60 inches (76.2 cm) in diameter. A pipe is fixed in said shallow hole through which it is to be drilled. A ship at sea For the hole, an underwater upstream pipe runs from the seabed to the subsea drilling platform. Ru. Flow diversion devices typically blow air from the top of the guide conduit, creating a risk of injury to personnel or equipment. An imbalance that can create an upward flow of drilling fluid in a conduit with sufficient momentum to below the rig floor and in the guide tube and borehole to safely release the same well pressure. between the rotary table and the rotary table. Typically, gas builds up in the fluid in the conduit. A blowout called a “kick” may be experienced when drilling the top hole. In many cases, especially when used at sea, a blow-out prevention device is installed before the drilling equipment is connected. A flow diverter is essential for this purpose. Diversion devices typically extend to a depth of several hundred feet below the ocean floor. A floating ship that installs a blowout prevention device on the seabed only after the casing is set. It is considered necessary for safe work in hole rigs.

There are two main types of prior art flow diverters. The first format is various Requires backing inserts of various diameters to accommodate tubing members of various diameters. including a flow diverter assembly. In such a flow diverter, it is not possible to completely close the open hole. I can not do such a thing. The second type responds to a kick in the annular portion of the hole by An annular blowout preventer is closed around a perforated pipe or other object. For the first time, the annular blow-out prevention device located above the vent pipe is located in the open position. The hole bottom drilling assembly can be changed by changing the packing element for pipes of various sizes. It is necessary to remove it while moving. Such work requires the rig operator to It's harsh. Flow diverters and equipment cannot close open holes, so there is no need to Without the object, the wellbore generally remains unprotected.

The second type of flow divider includes an annular blow-out preventer and a lower part of the preventer. height in combination with the side exit of the vent pipe requires excessive headroom below the rig floor. 5.

For both types of flow dividers that have been offered in the past, the outer valve of the vent pipe must be opened. , and close the valves that typically lead to the sieve in the drilling rig's fluid system. This necessity has created significant safety problems.

In the past, the valves were closed by rig personnel while inspecting the diverter. However, after the flow diverter was activated during drilling, the outer valve could be closed accidentally. It has been kept in chains. If an element of the control system is accidentally connected incorrectly, the shunt device In some cases, all the valves and flow diverters themselves would close at the same time. Conventional technique Technical flow diversion devices are closed around the borehole pipe or other objects in the wellbore. If the flow diverter is Flow diverters could explode, resulting in loss of life and property.

It is generally desirable to provide a definitely safe flow diversion device. That is, , a kick occurs while drilling a shallow wellbore before installing a blowout preventer. and kick, even if the control device is connected incorrectly or malfunctions. Even if the flow dividing device itself does not generate pressure or cause an explosion, it must be regulated to prevent it from generating pressure or causing an explosion. I can't.

Therefore, the present invention is installed below the rotary table of the drilling rig, and the an upwardly connected flow diversion device having at least one outlet passageway in its wall; a flow dividing device including a housing with a backing element disposed within the housing; element and an annular piston arrangement for movement from a first position to a second position. , in a first position the wall of the piston device is connected to the outlet passageway of the wall of the housing. and internal fluid communication, and in the second position the walls of the piston device are the annular backing element without preventing the internal fluid from communicating with the outlet passageway. Provides a flow diverter that presses closed around an object extending through the housing do.

One of the features of the present invention is that the insert path can be used within the flow diverter for pipes of various sizes. There is no need to change the drilling time, tedious work and work on the rig floor. The work setup can be omitted, and even if there is no object in the hole where the flow diverter is inserted, It is a good idea to safely divert the flow at any time.

Another advantageous feature of the present invention is the ability to seal objects extending through wellbore holes of varying diameters. or provide a device that completely closes the oil well hole, even if there is no object in the hole, and It also eliminates the need to install ventilation piping below the flow divider.
