A blowout in futures refers to a continuous burst of rising prices or a huge increase in trading volume or a huge increase in the number of investors. This blowout in futures is mainly understood in terms of the magnitude of the change.

Blowout is a phenomenon in which formation fluids (oil, gas and water) continuously and uncontrollably pour into the wellbore, erupting out of the ground or invading other low-pressure layers. Nowadays, it is also often used to describe events or other uncontrolled continuous occurrences with great changes.

Blowout is a phenomenon in which fluid in the formation erupts out of the ground or flows into other formations in the well. It mostly occurs at sites where oil and natural gas are exploited. There are many reasons for blowout: inaccurate control of formation pressure, low mud density, reduced height of mud column in the well, drilling and pumping, and other improper measures. Some blowouts are normal, but in the event of a blowout accident, if the natural gas encounters sparks after being ejected, it will burn, so it is very dangerous. A common rescue method is to pour dense barite mud into the well to increase the pressure and prevent the blowout from continuing.

Blowout is a very taboo accident in oil or petroleum gas extraction. During drilling, mud must be injected into the wellbore to balance the pressure in the underground formation. However, when the underground pressure test is inaccurate during the survey, the density of the injected mud is too low, or the formation pressure suddenly increases, the oil or gas in the formation flows into the wellbore and spurts out of the ground uncontrollably, resulting in a blowout. A blowout occurs. It is often accompanied by toxic gases, causing greater harm to the environment and people. The method of controlling a well blowout after it occurs is called well killing. The main methods of killing a well include the driller killing method and the engineer killing method. The driller killing method is to discharge the gas or oil from the well first, and then replace the original too much oil with heavy mud. For light mud, this method takes longer and is often used when weighting equipment is insufficient. The engineer killing method is a method of driving the well pipe into the well pipe at one time after calculating the required amount of mud. This method is faster, but the materials must be guaranteed.
