Quick Answer: What Is Choke Bean?

What does full choke mean?

Full Choke has the tightest constriction.

For distances beyond 40 yards.

The full choke will give a shotgun user the most accuracy out of any other choke.

The reason for this is because it constricts the shots very tightly when they come out of the barrel..

What is a kill line on a drilling rig?

1. n. [Drilling] A high-pressure pipe leading from an outlet on the BOP stack to the high-pressure rig pumps.

What is a choke in oil and gas?

Most oil and gas production facilities use a device known as a choke to control the flow of fluids produced from wells. … The choke is designed to handle an erosive service in the form of sand particles in the fluids.

What is a wellhead choke used for?

Wellhead chokes are used to limit production rates for regulations, protect surface equipment from slugging, avoid sand problems due to high drawdown, and control flow rate to avoid water or gas coning. Two types of wellhead chokes are used. They are (1) positive (fixed) chokes and (2) adjustable chokes.

What is choke size?

A choke is simply a tapered constriction of the gun barrel’s bore at the muzzle end. The exit end of the choke is smaller by some dimension than the actual bore of the barrel. … As a general rule for standard chokes the total range will be between . 000 and . 045 thousandths of an inch under bore diameter.

What is a positive choke?

A choke in which the orifice size must be changed to change the rate of flow through the choke. See choke and orifice. Back to Glossary.

What is a choke and kill manifold?

Cameron’s choke and kill manifold provides control of flowback or treatment fluids. The choke and kill manifold system consists of high-pressure valves, chokes, pressure sensors, connecting blocks, spool spacers, buffer tanks, flanges, and instrumentation configured together.

Should the choke be open or closed?

The choke is a plate in the carburetor that opens and closes to allow more or less air into the engine. … When doing a cold start, the choke should be closed to limit the amount of air going in. This increases the amount of fuel in the cylinder and helps to keep the engine running, while it is trying to warm up.

Is it bad to run an engine with the choke on?

Leaving the choke on while operating will result in excessive fuel consumption, irregular engine power performance and eventually may even damage the engine. … Some engines utilize a manual fuel primer bulb to enrich the ratio of fuel in the fuel air mixture for initial engine starting.

How do you kill a well?

Well kills during drilling operations Allowing formation fluid to enter into the well-bore. This influx of formation fluid is called kick and then it becomes necessary to kill the well. This is done by pumping kill mud down the drill pipe, where it circulates out the bottom and into the well bore.

What is the function of choke valve?

A choke valve is sometimes installed in the carburetor of internal combustion engines. Its purpose is to restrict the flow of air, thereby enriching the fuel-air mixture while starting the engine.

What is choke control?

A choke control is a fuel and air mixture control system found on many carbureted engines. Engines with fuel-injection systems do not have carburetors, so they won’t have choke controls. … The expression; “choke the engine ” refers to placing the carburetor manual choke control into the engaged (starting) position.

What happens if choke is left on?

What happens if you leave the choke on too long? Leaving the choke on for too long will cause unnecessary engine wear and waste fuel. This is also bad for the environment. One a cold day, the engine can need more fuel than usual to get running – this makes the mixture ‘rich’, and this is what the choke does.

What is kill mud?

A kill weight mud is a mud with a density high enough to produce a hydrostatic pressure at the point of influx, or where the kick is entering the wellbore, that will be sufficient enough to shut in the well and thus killing the well.
