Home Furnishing Feng Shui is like a complicated and huge machine. It can be controlled by interlocking and constantly changing. Some of the materials collected today are based on a simple and practical perspective, to give you an introduction to Feng Shui.
Room Feng Shui: room orientation
A good room feng shui is nothing more than having a spacious, airy, sunny room, and the room orientation plays a decisive role for this. Generally, the northern hemisphere houses are facing south, which can make the sunshine time the longest and the room air light is the best.
Room Feng Shui: House configuration
House configuration: door
The gate is the total import and export of a house, and the door of each room is also a small entrance and exit. The door is suffocating, and the importance is self-evident. All good and bad are determined by it. The shape of the door should not be skewed and the height is different. The stairs should not be straight to the door, and the door should coordinate with the room.
House configuration: stove
The stove is an important financial position for the family. When you enter the gate, you can't see the stove at a glance, otherwise the fortune can't be hidden. The stove can't be opposite to the toilet, and it is easy to get sick. The stove symbolizes the fire. If it is in a straight line with the sink, it will be a taboo for water and fire, which will lead to family misfortune.
House configuration: master bedroom
The master bedroom is where the owner rests and sleeps, affecting the health of the owner, career, emotional aspects, and relationship between husband and wife. The main bedroom door should be avoided to face the other doors, and excessive air circulation will reduce the comfort of the master bedroom. More attention should be paid to the bed. There is no contraindication to the mirror, the door can not be relied on, and the beam cannot be pressed.
House configuration: decorations
A good home feng shui, there are always some unavoidable shortcomings, but the feng shui masters will not let their existence harm the owner, but will set up some feng shui decorations in a certain position to dispel. Common feng shui decorations include Feng Shui fish, Feng Shui plants, scorpion, Guanyin, Buddha, tiger, jade and so on.
The layout of the room is more complicated. How to meet the favorite decoration effect at the same time, while sitting in the room feng shui of a prosperous house, it is necessary to coordinate each part of the whole house, which is also a test of the design level.
With the continuous development of drilling production, the use conditions of drilling rigs have become more and more diversified, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling method, drilling depth, borehole size and drilling tool size, and drilling area conditions (such as electricity or fuel, transportation, and meteorological conditions).
1. According to drilling method
(1) Impact drilling rigs, such as wire rope impact drilling rigs (drilling rigs), vibration drilling rigs, etc.
(2) Rotary drilling rigs, such as those used in rotary drilling.
(3) Downhole power drilling tools, such as rotary drilling tools, turbo drilling tools, screw drilling tools, electric drilling tools, etc.
2. Divided by drilling depth
(1) Ultra-deep well drilling rig. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of more than 7000 meters, and a maximum hook load of more than 4,500 kN.
(2) Deep well drilling rig. The drill rod is 114 mm in diameter, the nominal drilling depth is 4000-7000 meters or more, and the maximum hook load is 2250-4500 kN or more.
(3) Drilling rigs for medium and deep wells. It adopts a drilling rig with a diameter of 114 mm drill pipe, a nominal drilling depth range of 1500-4000 meters or more, and a maximum hook load of 900-2250 kN or more.
Three, according to power equipment
(1) Diesel Engine-driven drilling rigs, which use diesel engines as power through mechanical transmission or hydraulic transmission.
(2) AC driven drilling rig, suitable for use in oil fields with industrial power grids.
(3) The drilling rig is driven by direct current, and the working unit is driven by a direct current motor.
Fourth, according to the driving mode
(1) Drive alone. Each working machine is driven by generators of different sizes, which are mostly used for electric drive. The transmission is simple and easy to install, but the power utilization rate is low and the total equipment mass is large.
(2) Unified drive. The three working units of drawworks, drilling Pump and turntable are driven by the same power unit. Most drilling rigs use this scheme. The unified drive can also include only one drilling pump, and the other drilling pump is driven separately. The unified drive drilling rig has high power utilization and can be adjusted mutually when the engine fails, but the transmission is complicated, installation and adjustment are troublesome, and the transmission efficiency is low.
(3) Group drive. The combination of power is between individual drive and unified drive. There are two options for three working machines. The power utilization rate of this kind of drilling rig is higher than that of a single drive, and the transmission ratio is simple to drive in a unified manner. Two sets of working machines can also be installed on different heights and scattered sites.
