Abstract:

The second member of Xujiahe Formation in Penglai area of central Sichuan Basin is of great potential for gas exploration, but on the other hand, the reservoir is also characterized by lowporosity and lowpermeability, complicated pore structure and well logging response characteristics, so the exploration and development effect is influenced by these existing problems. In order to improve the oil and gas exploration degree and to find more high-quality reservoirs and favorable gas bearing zones, this paper studied the generation, storage, capping, migration, trapping and preservation of the second member ofXujiahe Formation together with their matching relationship with each other, and predicted the favorable gas bearing zones bymaking full use of drilling, logging, cores and slices data based on the previous research
results. The research results showthat:①the source rocks are of great potential for hydrocarbon-generating, and Penglai area is located in the superior place for gas accumulation with effective trap; ② the mudstone of the third member of Xujiahe Formation can be effective cap rocks;③ source-reservoir-cap rock assemblage is in a good form, the relatively stable hydrodynamics are in good conditions for gas accumulation. The reservoirs of the second member of Xujiahe Formation are generally in the favorable tectonic and sedimentary facies belt. Sedimentation is the foundation for reservoir forming, diagenesis is the key points for reservoir quality, while the fracture development determines the productivity of reservoirs. The prediction of the favorable gas bearing zones can provide certain references for next exploration deployment in the study area, and it is favorable for the petroleumexploration in some areas with similar reservoir characteristics
