The special problems associated with the production of oil and gas directly result from water being present in the fluids which the wells produce; and these waters are almost always salty or acidic, or both, so that they tend to rust or corrode

The idea of drilling wells was born in the middle of the last century. In Russia it |
|||||||||||||||
|
was suggested by the engineer F.A. Semenov, and it was he, who started drilling oil |
||||||||||||||||
|
wells on the Apsheron peninsula. |
|
|
|

|
|
|
НИ |

|
|
In the USA the first wells for oil production were drilled approximately at the |
|||||||||||||||
|
same time by E. Drake. The drilling of oil wells was also started at the same time in |
||||||||||||||||
|
Canada, Germany, Romania and Italy. |

|
|
|
|
|
|
In the early days of oil industry all wells were drilled by the percussion system, |
|||||||||||||||
|
in which a chisel shaped bit travelled up and down at the end of the rope making the |
||||||||||||||||
|
hole deeper. |
|
|
|
|
|
|
|
|
|
|
|
|
|
|||
|
|
At the beginning of the 20th century this method was replaced by rotary system, |

|
|
|
|

in which different sorts of bits rotate at the end of a pipe crushing rock at the bottom |

fluid |
brings the |
cuttings to the surface. When drilling by this |

|
method the bit is |

power required to rotate the turbine is provided by theи |
drilling fluid circulation. |

turbo-drill is particularly valuable is drilling theлdirectional and offshore wells. |

The Black Pearl of Tatarstan |
|
|
|
|||||
As a result of the rapid development of the famous Romashkinskoye oil-field |
the autonomous republic in the very centre of the country became an oil-producing |
||
|
к |
|
region of international significance, just like it was predicted by academician Ivan |
||
Gubkin. |
|
тр |
Oil production became the national profession of persistent and hard-working |
people of Tatarstan. When the proletarian writer Maxim Gorky visited the Apsheron |
|
peninsulaе |
at the beginning of the 20th century he saw the dark oil hell (ад) and |
described the inferno (пекло) of Apsheron oil-fields with their primitive inefficient |
|
л |
26 |
|
|
drilling methods, slow production techniques and polluted environment. |
|||||||||||||||||
|
Romashkino is nothing like the images of Maxim Gorky descriptions; this oil-field |
|||||||||||||||||
|
stands out with clear streams of natural springs and with the bright green of |
|||||||||||||||||
|
preserved birch groves. The first wells of Romashkino took half a year to drill and |
|||||||||||||||||
|
even longer. But special technical schools and institutes were being established in |

All oil wells are drilled by means of a bit. A bit is a tool which drills the |
|||||||||||||
ground and progressivelyн |
deepens the well. |
|
|
|
|
|
|
|
|
The properties of the rock to be drilled determine the type of a drilling bit to be used. Depending on how they operate on the rock drilling bits are classified as drag
|
к |
|
or cutting bits, and as roller bits. |
||
|
Drag bits shear or cut the rock. Roller bits have a crushing action. Two and |
|
three wing bitsтрare used for drilling in soft clays, clay shales and other rocks which |
||
are not particularly hard. |
||
л |
Roller bits are designed with two, three and more rolling cones, each of them |
|
can rotateе |
independently. Three-roller bits are mostly used for drilling hard rocks. |
|
|
Diamond bits are widely used for boring wells. Their advantage as compared |
|
|
|
28 |
Э
with ordinary bits lies in their longer service due to hardness of the diamonds sat in their surface. Diamond bits do not require frequent replacement, and their drilling speed, especially in sinking deep wells, is much higher than that of bits without diamonds. Not many years ago a rock bit would last for only 6 to 12 hours before wore out. Now rock bits last for two or three days on normal depth wells.
