Block geological modeling, low permeability reservoir fracturing seepage modeling research.
Geological model and fracturing seepage model of low permeability reservoir are established to describe fine geology, including permeability distribution, formation pressure distribution and dynamic change of fracture scale.
Based on the analysis of production data and pressure recovery test, the comprehensive evaluation method is studied.
The mathematical model of pressure and production after low permeability reservoir reconstruction is established.
Considering the factors of homogeneous infinite reservoir, fractured well and boundary type, the expressions of production and pressure derivative are established.
A well test interpretation chart for production test analysis of fracturing fluid is established.
The drainage data is used to calculate the parameters, and compared with the formation parameters obtained from the inversion of shut in pressure recovery test.
Combined with geological modeling, fracturing modeling, drainage analysis and pressure recovery test analysis.
The evaluation method suitable for low permeability reservoir after reconstruction is established.
