Living in the north compared to living in the south
I was born in the north, in the south of the university. When I was in college, I was living in a typical South and a typical north.
The South was not talking directly to the people, the university has tried to bend and people talk, found that really tired, brain cells are not enough to say.
So the South after a long period of time to hone first, the brain in some ways than the north. For example fine, eat a small mouth, a Minzui, especially in public, to see this, let I the northerners niwai shortage. My own careless in the bedroom, to the public, or will you pay little attention to the.
The northerners speak with me, this is lacking, I spoke with a cross taste, sometimes make the rivalry. This may be the shyness of the south.
Whether the South or north of the most important or look at the character we all have more than their own.
As I see not pleasing to the eye are direct, the south of what is not pleasing to the eye would politely, South North, listen euphemism strength, the more understand me more confused loaded, encounter less southerners do it in a hurry. I want to stay is not suppress the uncomfortable. The most important point, southerners say don't like talking to someone not directly, he is clearly a Tuotuo fresh examples, and bend sometimes too far.
In short, the south, the living environment and lifestyle in the north, created a different character of the South and the north.
Directional drilling: purpose and operation
The wellbore along the pre designed inclination and azimuth drilling method to the horizon. Mainly used for: 1, restricted by terrain, such as oil and gas buried in towns, mountains, lakes, or farmland; 2, offshore cluster well drilling; 3, because of its special geological structure (such as faults, cracks, or dip too large), drilling directional well is conducive to the exploration and development of oil and gas reservoir; 4, processing downhole accidents, such as sidetracking, drilled in order to stop the blowout fire rescue wells.
Directional drilling method is generally used for directional drilling in the bottom hole, and it can be used in the construction of a rotary steering wheel.
With the development of the petroleum, the occupied land also continued to expand, in order to save land resources, reduce land costs, on a site or a drilling platform, a planned drilled several or dozens of mouth vertical wells and directional wells, they are referred to as cluster wells.
The cluster wells to develop oil field has obvious economic benefits, cluster wells in developing offshore oil field is used in the offshore platform, artificial island, saves a great deal of infrastructure investment, improve the drilling speed of oilfield development efforts.
The cluster wells of each single well is a directional wells were essentially the same in general site arrangement well number of cluster wells and general directional well design. In order to optimize the overall development of an oil field or area, the overall optimization design of the cluster wells should be carried out.
A: if the ground conditions allow more uniform set of cluster well pattern arrangement, often using radiation.
B: if the ground is strictly limited, only the site layout cluster to the outer cone drill targets when the dispersion type.
But in recent years with the continuous improvement of horizontal drilling, petroleum industry and vigorously implement the horizontal wells, horizontal branch well, horizontal well can in the reservoir to avoid bottom water and gas cap, the output of single well average 3 - 5 times; development of low pressure, low permeability, thin, heavy, and shale fracture, small sea reserves marginal oil and gas reservoir economic efficiency improved significantly, the oil recovery rate is high; water vapour cone into slow, fracturing effect is good.
Generally put into the oil layer well section of the slope more than 85 degrees to become - Horizontal wells.
