At the early stage of development, on the basis of the recognition of the pore spaces being pores, the development plan was schemed according to the development model of common sandstone and conglomerate reservoirs, but, after two years development and under the condition of less than 5% recovery, the productivity declined from 150 t/d at beginning down to 20 t/d, comprehensive water cut was as high as 80%. Under the condition of no core data and the logging series being not suitable for fracture study, started from analyzing the contradiction exposed in development, by means of wall coring , pressure build-up testing, the reservoir lithology difference and accumulation relations between the types, as well as the application of the indentification of accumulation types on the development of Yan 107 conglomerate reservoirs, are discussed in detail.Read More
