Antlers Farm - Plum Dam Construction Jialing Gas Reservoir Geological Modeling And Its Application

Reservoir Geologic Model is the core of Geologic Model. During evaluate and exploit the reservoir, establish 3-dimensional quantitative geologic quantificational model is the goal of reservoir study. Stochastic Simulation has been applied widely to reservoir simulation and prediction, for its inimitable superiority on expressing reservoir heterogeneity, evaluating incertitude, analyzing venture, choosing project and etc, and it has become outstanding development direction of geologic modeling technique.On account of the little reservoir thickness, the low porosity, penetrability , and well-output of Lujiaochang-Liziba formation Jialingjiang reservoir, we establish the Parameter Distributing Model of reservoir, to enhancing the geologic cognition, analyzing advantageous reservoir, and offering geologic warrant to Reservoir Numerical Simulation.By the numbers study, this paper acquired results as follow:(1) According to the study results of modeling methods and reservoir character of Lujiaochang-Liziba formation Jialingjiang reservoir, we adopt stochastic Simulation method "Multi-parameter Coordinated Sequential Gaussian Simulation" to build a geologic model. The model expressed factual characters of reservoir, and insured the high precision of later Reservoir Numerical Simulation.(2) Based the geologic model we built, this paper analyzed parameter's distributing characters and predicted the advantageous reservoir. Parameter distributing figures show us that porosity, penetrability and saturation in Lujiaochang-Liziba formation Jialingjiang reservoir, are related less to formation, but under the control of the lithology. The advantageous reservoirs mostly distribute hereabout high of the Lujiaochang-Liziba formation.(3) In virtue of the geologic model, this paper verified gas reserve, established reserve distributing model, and make the reserve distributing figures. These figures show us distributing characters of gas reserve.(4) By analyzing dynamic and static characters of reservoir, we consider that, on the well-output, the key is fissures' develop degree, and the base is porosity and saturation.(5)By analysis of dynamic characters of gas reserve, Reservoir Numerical Simulation, and fissures' develop characters, ascertain distributing of remainder gas.
