Abstract
The SDN block of the Sulige gas field belongs to the largest demonstration area for tight sandstone gas reservoirs in China, horizontal well production number of blocks in about 40% of the total number of production Wells, horizontal Wells produce block total annual output of more than 75%, but the tight sandstone gas reservoir horizontal well production decline rate is fast, cause the horizontal continuous shorten production period, natural gas well management difficulty is big, Seriously affect the stable production of the block. In this paper, the numerical simulation method, the formation pressure, effective thickness, reservoir permeability, water saturation, horizontal section length, horizontal segment section number, pressure fracture length, influenced by the mode of production of horizontal well production decline, and the influence factors sensitivity analysis, based on the basis of analyzing many factors influence, The sensitivity study of controllable factors such as production system, fracture half-length and number of fracturing stages is mainly carried out to quantitatively analyze the influence degree of controllable factors on the decline, so as to provide important technical support for the optimization of block control decline strategy and fine management of horizontal Wells.
