Abstract


Low permeability gas reservoirs horizontal wells capacity analysis theory , combined with gas the Zang geological and gas well production and gas field horizontal wells inflow and outflow of the dynamics and impact of factors to determine a reasonable working system of horizontal gas , the main research results obtained are as follows : ( 1 ) the establishment of low permeability gas reservoir horizontal well productivity analysis of mathematical models based on access to the low permeability gas reservoir horizontal well production formula , consider the effect of formation damage and non - Darcy the established horizontal wells binomial deliverability analysis equation for horizontal wells can analysis provides a theoretical basis . (2 ) the use of established binomial deliverability equation of low permeability gas reservoirs horizontal wells , horizontal wells for Jingbian Gas Field , analysis of the gas layer thickness , the length of the horizontal section , anisotropy , formation damage and starting pressure gradient on the inflow the dynamic effects . ( 3 ) to establish the theoretical formula of low permeability gas reservoirs horizontal wells and vertical wells productivity index ratio to the Yongpyong well as an example , the pressure gradient from the gas layer thickness , the length of the horizontal section , anisotropy , formation damage , start the aspects compared the productivity index of horizontal wells and vertical wells . ( 4 ) the establishment of a horizontal well production system analysis theory and method . Made Jingbian gas field production systems analysis curve of the horizontal wells , formation pressure and diameter of the production system analysis curve , provides a means and method for horizontal wells with production . (5) establish the theories and methods of liquid carrying capacity of horizontal wells . Make the liquid carrying capacity of the gas field horizontal wells in Jingbian inflow dynamic coupling curve , formation pressure and diameter of the coupling curve . (6) using the empirical method , production system node analysis method , considering the critical production method and gas production curve method for carrying liquid analysis reasonable system of horizontal wells with reasonable production yields obtained under different methods of horizontal wells . The results of this study on the use of horizontal wells to develop low permeability gas reservoir has a positive significance .
