Well Test Interpretation And Deflation Radius Of Xishanyao Formation Gas Reservoir In X1 Well Area

Well test interpretation method and discouraged radius calculation method for the study of the main objectives of this paper are suitable geological characteristics Xishanyao actual gas reservoirs X1 well area for gas reservoir development adjustment of dynamic analysis and provides the basis for low permeability gas reservoir. Development plays a certain role in promoting.On the basis of low-Darcy flow, the study established a finite conductivity vertical fracture bilinear flow model, finite conductivity vertical fracture wells with finite conductivity vertical fracture wells with three linear low-speed non-Darcy flow model and shed three linear flow model. And drawing a sample version of the curve, the curve sensitivity analyzes, combined with the actual geological characteristics and wellbore construction and testing process, selected homogeneous finite conductivity vertical fracture bilinear flow model, the boundary conditions for the infinite boundary, and well test data for the calendar year were re-interpreted, the interpretation of the results and interpretation of results were compared.On the basis of traditional computing discouraged radius formula based on the calculation method of the new study discouraged radius consider traffic and traditional calculation methods, software intended result of legitimate and well test interpretation method of calculation were compared. Gas reservoir recovery from the low levels of the reasons well spacing, four development approach, producing water and retrograde condensate phenomenon analysis carried out, and ultimately the blame XI well area Xishanyao gas reservoir recovery low level. The reason is well away from the larger and retrograde condensate phenomenon.
