I. How Do Petroleum Machines Work in the Oil Extraction Process?
The drilling team starts drilling using drilling machines. The drilling team will first drill one or two wells at the destination, which are called exploration wells. The purposes are as follows:
(1) To determine the geological stratification of this block. Professional terms include geological stratifications such as the Yan'an Formation, the Yanchang Formation, the Majiagou Formation, the Taiyuan Formation, etc.
(2) To find out whether the block contains oil/natural gas. If it does, what are its abundance, permeability, etc.
If the exploration wells in this block indicate that the block contains oil and gas, then this block will soon enter the large-scale oil and gas extraction stage. The most obvious feature is that a large number of wells will be drilled. Regarding drilling, in fact, many people think that oilfield exploration and development are all about drilling. In reality, drilling is just a small part of the oilfield development process.
Logging machines are used for logging. Logging can be divided into several aspects, including completion logging, triple-combination logging, perforation, production logging, etc. As mentioned above, once the drilling team has completed drilling the well, it's time for the logging operation. The purposes of logging are:
(1) To check whether the well drilled by the drilling team meets the design requirements, such as the well deviation, the horizontal section, etc.
(2) To evaluate whether there is crude oil/gas in the formation.
(3) If it exists, what are the horizons, depths, and which horizons are of mining value.
Fracturing machines operate to fracture the formation, expanding the cracks opened by the perforations, so that the oil can flow into the casing more quickly.
Oil production machines extract oil. After the fracturing is completed, it's time for the oil production team to install the oil production machines, commonly known as the nodding donkey or pumping unit. At this time, the oil is extracted, and you can see the real oil.
II. Why Can't Petroleum Machines Be Stopped?
Many people have heard that petroleum machines cannot be stopped during operation, but they don't know why. So, why can't petroleum machines be stopped?
In fact, in oil extraction, petroleum machines can be stopped, but they cannot be stopped easily. If they are stopped, the cost of restarting the machines will increase, and the maintenance cost of the machines will also rise. Therefore, generally, during oil extraction, petroleum machines will not be stopped easily.
