油田裏為甚麼總有一根管道在噴火，日夜不息，不怕引起危險嗎？

Oil is known as the "blood" of industrial development. It is also the blood of the Earth It is often hidden a few dry meters underground We need to use every means to get it out If you've been following the news I'm sure you'll find a strange phenomenon like this That's right next to the oil well There's usually a tube This pipe is not spouting oil It's a blazing fire Is day and night What is the point of this Do it on an oil field Aren't you afraid of an explosion from an open flame Welcome to the Science of Revelation I'm Jack Sparrow You want to drill for oil You first need to find where is the oil But the oil is buried in the ground What technology are we going to use to find out That's where 3D seismic detection comes in You heard me right You need to artificially trigger an earthquake And then using seismic waves Velocity of propagation in different media Different propagation paths Distinguish between different substances It is like a B ultrasound, color ultrasound or CT for the earth High resolution of 3D seismic imaging It's a good representation of the underworld Subterranean ancient river The ancient lakes The ancient mountains Ancient karst landforms The faults and so on are in plain view Three dimensional seismic detection technology The most widely used is the field of resource and energy exploration It's global oil right now Coal etc. Main exploration techniques for underground natural minerals Nanpu Oilfield of Bohai Bay discovered in China at present Pueverbright Gas field, Sichuan Province Tazhong "large gas field in Tarim Basin It's all thanks to high-precision 3-D seismic detection Discovery of oil You need a rig and As the drill progresses It's going down the pipe To keep the walls from collapsing When the drill breaks through layers of rock In the case of calculation can not be wrong We should be able to reach the reservoir Under ordinary circumstances Deep underground there is pressure from the Earth's inner workings The oil There's a good chance it's going to pressure right out of the well It would have been easier Saved from the depths of the earth The cost of getting the oil to the surface So here's what you're most concerned about What about the "fire-breathing" pipe in the oil field First we need to make sure What's burning in this pipe Is the oil? Must be testing the quality of the oil Let's see if it burns But it's not actually oil that's burning here It's natural gas How do oil fields produce gas Explain the problem Start with the different types of oil fields Oilfield is a rather general term Because of the area where the oil was found In the formation of oil Often with some natural gas The official name for this gas is associated gas If there's more oil in the mine It's called an oil field Otherwise it's called a gas field If the oil and gas contents are similar Then this kind of mining area is called oil and gas field Oil fields are mostly oil But there's also some natural gas These flames burn It's the natural gas that forms with the oil fields Isn't natural gas a resource just like oil If only we could mine together It can also bring in some extra income This is not the case We talked about that before The burning of associated natural gas It's mostly found in oil fields Especially offshore fields If it's a gas field or oil and gas The natural gas will not go unpunished But because oil fields are produced primarily from oil It's not the associated gas inside To capture natural gas You need an extra set of equipment and Oil fields are mostly oil Associated natural gas is only a small part of this So for this small fraction of natural gas You need a whole set of facilities But also the supporting technical staff and so on The associated gas is not unrecoverable It just costs too much Technically no problem Lose money on the economy No one wants to do this business But even if it's not cost-effective to recover the gas Well, that can be left alone It just burns up Won't it be dangerous Just the opposite is true Burning off the gas is not dangerous It's all about safety Natural gas and air are mixed in a certain proportion An open flame will explode directly During construction A spark of friction from a drill I might be able to ignite the gas Even the surrounding oil will be ignited From the economic benefits and safety Instead of letting it accidentally explode It's better to burn it off It was a last resort Due to the exploitation of oil fields Inevitably, some associated gas will be produced and Some of this natural gas It's also mixed with some sulfur-containing gases Like hydrogen sulfide Hydrogen sulfide is a colorless gas with irritant and compartment properties Low concentration contact Only the local irritation of respiratory tract and eye The systemic effect was more obvious at high concentration The symptoms are central nervous system symptoms and ventricular symptoms Hydrogen sulfide has a rotten egg smell But very high concentrations quickly cause fatigue And don't notice the smell Let's have a look Hydrogen sulfide poisoning occurred in China On April 17 of this year, just after 8 a.m Yuyao Linshan Town There was an incident of hydrogen sulfide poisoning Three people were killed The tragedy of three people being injured It started when a worker was adding sodium sulfide to an exhaust tower Due to operation error Cause himself to fall to the ground poisoned Then the workers noticed something was wrong And tried to pull him Immediately he fell down with poison Finally, four more people rushed to the rescue Only one of them came out Later that These workers are supposed to be in The core environment of the gas leak The concentration of hydrogen sulfide is very high It's about as close to a blow as you can get to death Otherwise, there shouldn't be six people in a row A situation where only one person ends up getting out For such a terrible gas It's better to burn it in a straight fire Compared to that paltry profit Or is life more important Burning off minimal amounts of associated natural gas in oil fields It's kind of a common practice However, With the development of science and technology and technological progress In recent years, Sinopec Northwest Oil Field V A new set was built for gas harvesting And transport processing of the recovery device The amount of gas Tahe can recover in a day Three million cubic meters from five years ago Increase it to 8400,000 cubic meters The pattern of Adopt "self-use plus power generation plus export" This part of energy will be fully recycled The recovered gas can then be used to generate electricity Meet the heating of the nearby area Food and beverage Lighting requirements In 2010, Associated gas for power generation in Tahe Oilfield That's 123 million cubic meters It generates 297 million kilowatt hours of electricity Basically meet the electricity demand of oil field At the same time Gas gathering and transmission stations have also been built in the field It can act as a hub to manage the flow of natural gas The Northwest oil field is also tapping into oil and gas potential Newly built Area 12 and 10 in Tahe Oilfield Implement fire extinguishing moment engineering About 150,000 cubic meters of associated gas per day in both zones It will all be recycled More associated natural gas can be recovered every year More than 50 million cubic meters so With the gradual spread of these technologies Our future I might not see the pipe that shoots the flames Instead, it is the rational use of resources Of course, Jack Bauer still wants to make good use of fossil fuels We can continue to develop wind energy Solar energy and other green energy After all, protect the environment, protect resources Is to protect ourselves How else do you think associated gas can be used Let us know in the comments We'll see you next time
