Abstract

Based on the distribution of underground fracture and faults in Lunnan area, the distribution of underground liquid was investigated. According to the well data of petroleum exploration in Lunnan area, the influencing factors of fracture distribution was analyzed. Model preferences were studied and all influencing factors were considered, such as depth, temperature, confining pressure, reconstruction in tectonic movement, and randomicity. Fracture probability was obtained through numerical simulation of stress field, and the relationship between fracture distribution and liquid distribution was analyzed. According to the calculating results, liquid distribution was predicted, and liquid movement was analyzed through geological analysis. By comparing liquid distribution with the results of liquid test in wells, it is found that liquid moves through faults and accumulates to fracture areas. Faults are channel-ways of liquid movement and high fracture probability areas near faults are favorite areas for liquid accumulation. Because Lunnan area is a typical area for liquid movement research in carbonate rock areas with complicated influencing factors and four fracture types, this method can be applied to other carbonate rock areas, especially, those with violent faults activity and complicated fracture distribution. Finally, some advice is proposed for liquid movement investigation in carbonate rock area.
