Embodiment 1
[0041] Example 1 Correlation Analysis of Test Gas Output, Gas Content and Each Index
[0042] The work area is located in the Changning-Weiyuan Shale Gas National Demonstration Area in the south of the Sichuan Basin. The horizon is the Longmaxi Formation rich in organic matter shale. The shale gas content is the sum of the free gas content and the adsorbed gas content, wherein the free gas content is obtained by an experimental method; the adsorbed gas content is measured by an on-site desorption method.
[0043] In this example, a correlation analysis is carried out between the test gas output and seven other indicators: total organic carbon content, organic matter maturity, shale gas content, fracturing index Fi, formation pressure coefficient α, burial depth and shale thickness, and extract The combination of total organic carbon content (TOC), fracturing index, formation coefficient and shale thickness is obtained.
[0044] Depend on Figure 1 ~ Figure 4 It can be seen t...
Embodiment 2
[0050] The work area is located in the Changning-Weiyuan Shale Gas National Demonstration Area in the south of the Sichuan Basin. The layer is the Longmaxi Formation rich in organic matter shale, and its cumulative development area totals 7,936.7 square kilometers. As of July 2013, there are 26 wells in the study area, including 6 wells in Changning block and 20 wells in Weiyuan block.
[0051] For technical routes and steps, see Figure 5 with Image 6 . The specific process is:
[0052] 1) Collect the index data required for the identification of favorable areas for production construction in the work area, the index data are total organic carbon content (TOC), organic matter maturity (Ro), shale gas content, shale thickness (H), Formation pressure coefficient, Young's modulus, Poisson's ratio, and burial depth. The above indicators are measured by conventional technical means.
[0053] 2) Combining the three indicators of total organic carbon content (TOC), organic mat...
