Abstract:
Based on the random function theory, three-dimensional geological model of the condensate gas reservoir in AT1 Block of Tahe Oilfield was built by the phase control and multi-parameter cooperative stochastic modeling method, and three-dimensional quantitative characterization of the gas reservoir was realized. Firstly, structure model of reservoir was built based on the data of drilling and core; secondly, structural model of reservoir was built under the control condition of substratum interface; thirdly, skeleton pattern of sandbody was built by sequential indicator simulation method under the sedimentary facies and geological condition; fourthly, phase preference was calculated with the skeleton pattern of sandbody, and then the final pattern was built; finally, physical parametric model of reservoir was built by sequential Gaussian simulation method under the control of effective skeleton pattern of sandbody. There are effective geological modeling methods that combined physical parameters with micro facies distribution, sequential Gaussian simulation method built the distribution model of physical parameters porosity, and optimization model was selected by geological analysis, analogy and statistics. The geological model built showed the tectonic framework, reservoir, fluid three-dimensional distribution of condensate gas reservoir in Block AT1 of Tahe Oilfield accurately and meticulously, and indicated that braided stream was complex and connected, physicality of reservoir was controlled significantly by facies, the direction of distribution was northeast, and the inhomogeneity was strong.
