| 摘要 |
The invention is directed at a method and apparatus for producing liquids, namely hydrocarbons, from a subterranean formation using a well having a collecting wellbore located at least partially within the formation. The apparatus is comprised of: a first downward wellbore having a proximal end communicating with the surface and a distal end extending beneath the surface; a second downward wellbore having a proximal end communicating with the surface and a distal end extending beneath the surface; a collecting wellbore for collecting liquids from the formation, located at least partially within the formation and communicating with the formation and the downward wellbores such that a continuous wellbore is formed from the proximal end of the first downward wellbore to the proximal end of the second downward wellbore; means for displacing the volume of liquids from the collecting wellbore into the second downward wellbore in order to develop a column of liquids within the second downward wellbore; and means for producing the column of liquids within the second downward wellbore to the surface. The method for producing the hydrocarbons is performed by using the apparatus. The invention is further directed at a method for drilling the well to be used in performing the method.
