Being unable to drive after drinking is already a rule that every driver must follow. However, many people do not know that some drugs cannot be eaten before driving. The following list of 10 types of drugs is not suitable for driving after the use, and I hope to remind the majority of riders.
1. Gastric motor drugs: such as metoclopramide, dizziness, lethargy and other side effects.
2. Hypoglycemic agents: hypoglycemic agents can cause hypoglycemia and appear hunger, palpitation, hand shake, dizziness, sweating, irritability, anxiety, general weakness and other symptoms, the degree of serious central nervous system memory loss occurs, the spirit is not Concentrate and so on.
3. Antimicrobial drugs: For example, metronidazole can cause headaches and dizziness.
4. Antiarrhythmic drugs: Such as quinidine, mexiletine and propranolol, etc., often accompanied by headache, vertigo, tinnitus and hypotension and other adverse reactions. If the dose is too large, it can even cause hypotension fainting.
5. Hypnotic drugs: such as barbiturates, chloral hydrate, etc., will appear after taking dizziness, fatigue drowsiness and unresponsive.
6. Anti-Cold Drugs: Most cold medicines contain antihistamines and have side effects such as drowsiness.
7. Antihistamines: Promethazine (phenagen), chlorpheniramine, etc., have a significant inhibitory effect on the central nervous system and can often cause side effects such as dizziness, headache, fatigue, trembling, tinnitus, and hallucinations.
8. Anti-angina drugs: such as nitroglycerin, propranolol, isosorbide and antihypertensive drugs. May cause pulsatile headache, blurred vision, dizziness and fatigue.
9. Anti-anxiety drugs: such as imipramine, doxepin and phenelzine, etc., often accompanied by fatigue sleepiness, unclear vision, muscle tremor, unresponsiveness and postural hypotension.
10. Antispasmodic analgesics: atropine alkaloids and post-matropine, etc. Common side effects are side effects such as blurred vision and palpitations.
To wake up before driving, drivers know that they can't drink before driving, but when they need to take medicine, it's impossible to stop the medicine for driving. It is recommended to stagger time and avoid danger. It is not recommended to drive within 4 to 6 hours after taking cold medicine containing anti-allergic ingredients. Anti-allergic drugs should be taken at the doctor's bedside to reduce the effects of side effects such as drowsiness. It is best not to drive while you are starting to take antihypertensive drugs, hypoglycemic drugs, and adjusting dosages.
Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells or wellbore.
It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow
drilling fluid to circulate and extraction to take place
The oil casing is a steel pipe used to support the well wall of oil and gas wells to ensure the normal operation of the whole well during drilling and after well completion. Several layers of casing shall be used for each well according to different drilling depth and geological conditions. Cement shall be used for cementing after casing is put into the well. It is different from TUBING and drill pipe and cannot be reused. It is a disposable consumable material. Therefore, casing consumption accounts for more than 70% of all oil well pipes.
Casing is a large-diameter pipe that serves as the structural retainer for the walls of oil and gas wells, or wellbore. It is inserted into a well bore and cemented in place to protect both subsurface formations and the wellbore from collapsing and to allow drilling fluid to circulate and extraction to take place.
Surface casing
- Protects the well from contamination in shallow water and gas layers.
- Supports the wellhead equipment and sustains the weight of the other layers of casing.
Intermediate casing
- Isolates different layers of pressure to facilitate normal circulation of drilling fluid and protect the production casing.
- Intermediate casing facilitates the installation of blow-out preventers, anti-leakage devices and tailpipes in the well.
Production casing (oil string)
- It is the conduit through which oil and gas pass from a below surface reservoir.
- It protects the well and separates fluids into various layers.
First, green pipes are threaded on each end. The threading is then inspected and, if necessary, rethreaded to ensure that the thread accurately connects to the coupling. The threading type includes STC/BTC/LTC. The casing pipes are strengthened by surface treatment and are subject to various inspections, including drifting and hydrostatic tests before they are coated and packaged into casing.
Casing pipes are ordinarily produced with outside diameter sizes of 114.3 mm to 508.0 mm.
