Research On Three-dimensional Geological Model In Kulong Area ,qingxi Sag,china

Deterministic modeling method, three dimensional geological model, sequential indicator modeling method, combination, Qingxi Sag.

Taking Xiagou Formation, Lower Crataceous Kulongshan area in Qingxi Sag, Jiuquan Basin as the research object, this paper constructed reservoir three-dimensional geological model using the deterministic modeling method and stochastic modeling method . First, distribution of fan delta plain, front and shallow lake mudstones are set up by the deterministic modeling method; then the space distribution of the rock type is built up based on sequential indicator stochastic modeling method； finally, high precision of rock model has been created with the combination of the deterministic model and the stochastic model. With the rock model as constraints，the three-dimensional distribution models of porosity and permeability are established using the Gaussian sequential modeling method, the model provides a solid geological foundation for the subsequent reservoir research and reservoir numerical simulation.
