Well pattern structure

The utility model discloses a well pattern structure, it includes: a plurality of straight wells, every straight well has predetermined drainage radius, be located directional well between a plurality of straight wells, with the drainage radius of two straight wells that the directional well is adjacent is underlaped, the directional well include from the decurrent first well section in ground and with first well section is linked together and is located the second well section of target zone, the hole deviation of second well section is 45 degrees to 85 degrees. Well pattern structure arranges the directional well through the on the basis of of the straight well well pattern current, and surplus oil between the well of can taping the latent power improves the oil reservoir producing degree between the well, especially can effectively employ transversely discontinuous, the vertical superpose or even the oil reservoir of superpose that vertically staggers. 本实用新型公开了种井网结构，其包括：多个直井，所述每个直井具有预定的泄油半径；位于所述多个直井之间的定向井，
