Abstract

The invention relates to a process for oil field developing in various developing stages using subsurface drains. The process for oil field developing using subsurface drains ensures the onflow of the deposit fluids towards the production well by selecting a production well (2) bored in the most productive and accessible zone of the deposit (1) around which an array of wells (4 and 5) is made, said wells being placed in concentric successive rows and being bored vertically at one or more levels. After reaching the deposit (1), the wells (4 and 5) are bored in a convergent and guided manner towards the production well (2), across the deposit (1), along a curved path in a draining zone (3) of the production well (2). The wells (4 and 5) are cased along the entire deposit (1) and are cemented or not up to the surface along the segment (b') located above the deposit (1), thereby making some subsurface open drains (5') and some subsurface closed drains (4') wherethrough the fluids flow in and towards the production well (2), both under the action of the deposit energy and under the gravity.
