Aiming at problems in development of clastic rock reservoirs in No.1 and No.9 blocks of Tahe oilfield, systematic research and demonstration were carried out. It's pointed out that, at first single well stimulation in the clastic rock reservoir should be carried out to reserve technology foundation, then development scale should be gradually enlarged to realize gas flooding between the wells, at last nitrogen foam huff and puff should be carried out. Nitrogen has low density, is not miscible… CONTINUE READING
