Hujianshan oilfield of An 201 block fractured reservoir development technology

Hujianshan oilfield of 201 block of Chang 61 reservoir is a typical fractured reservoir, since 2009 put into development, exposed part of the regional high water saturation, the wells in fractured water, lateral wells with low efficiency, high proportion of low yield wells, reasonable production pressure difference uncertainty, water driving degree is low, the production decline some problems, restrict the development of oilfield. This paper aiming at the problems exposed in the development of an 201 block, through the development mode, well pattern, injection production pressure system, injection parameters, comprehensive analysis and research, the development of technology policy in fractured reservoir is reasonable, has guiding significance for the development of similar reservoirs in the late.
