DRILLING

There are many ways of discovering the underground oil, but the only way to get it is to make a deep hole called a borehole, or a well, through the rock, earth and sand. The steel framework over the well is called a derrick. From this the machinery that drills the hole is raised and lowered.

The technique of well drilling goes far back into history. It is first mentioned in ancient Chinese manuscripts, which describe wells drilled as early as the third century A.D. to tap underground strata for brine. The wells were drilled with a heavy bit, which hung from a rope and was raised up and down by several of men jumping on a spring board.

The petroleum industry is traditionally considered to have been born in 1859 near Titusville, Pennsylvania where Drake drilled the first well. In Russia the first oil well was drilled in 1856 by a Russian engineer A.F. Semenov. At around the same time oil wells were also being drilled in other places, notably at Oil Springs, Ontario, Canada and Wietze near Hanover, Germany and there is some doubt as to which country should be credited with having drilled the first commercial oil well. All these wells were drilled by the cable tool methods.

The cable tool system was essentially a method of making a hole by repeated blows with a bit attached to a Уdrill stemФ, a heavy length of steel suspended from a wire rope. The hole was kept empty except for a little water at the bottom. After drilling a few feet, the bit was pulled out and the cutting removed with a УbailerФ, an open tube with a valve at the bottom. Steel pipes known as casing, of progressively smaller diameter, were run from time to time to prevent the hole from caving and to keep back any water flow.

Cable tool drilling was cheap, simple and effective for shallow wells, but progress was slow and no means was provided for stemming the flow of oil and gas when encountered under pressure. In such cases the wells blew out and spewed quantities of oil and gas over the countryside. The УgushersФ of these early days were spectacular but wasted a lot of oil and gas, and were a serious fire hazard.

The present-day method of drilling, known as the Уrotary methodФ was introduced at around the turn of the century. With this method, the bit, instead of moving up and down, is attached to the bottom of a string of steel pipes and rotated by means of a rotary table which turns the uppermost pipe or УkellyФ. УDrilling fluidФ or Уdrilling mudФ is continuously circulated down through the hollow drilling string, through the bit and back up to the surface through the annular space between drilling string and borehole wall. The drilling fluid flushes the cuttings out of the hole and, by the weight of its column, holds the fluids under pressure in formations penetrated by the bit, thus greatly reducing the risk of blowout.

A variant of rotary drilling is known as Уturbo-drillingФ. With this method the pipe is not rotated but is kept stationary and the bit is rotated on bottom by means of a fluid motor or turbine powered by the mud stream. Although the rate of penetration of the bit can be faster with this method than with conventional rotary drilling the bit wears out much faster, so that the overall efficiency is lower. However, the method has some application where high-grade steel is difficult to obtain, and where rapid bit wear is unimportant.

Superdeep Drilling

Our drillers have completed the stage of sinking a superdeep well. The drilling of a superdeep drilling well is of tremendous scientific interest because the majority of problems that interest researchers are still at the stage of hypothesis. It is very important to know the composition and physical state of interior spheres of the Earth, what physical and chemical transformations of matter are taking place there, or how these rocks move to cause the drift of continents and especially Ц the origin of the Earth.

Superdeep drilling is a very labour-consuming process. And all the more in arctic conditions. Each pipe coming to the drillers from the factory is subjected to electroscopic testing.

To reach the planned depth is a job so serious and so complex that the drillers must calculate literally every step. The geologists working on the superdeep well are using the latest methods of geological and geophysical research. They have obtained data which tend to change our concepts of the Уlower storeysФ of the EarthТs crust.
