The Sensitivity Study Of Formation Parameter In Horizontal Fractures

Along with oil field development, oil producing wells were entered the high water cutstage with complex oil/water distribution during the later period. In view of the complicatedfield problem which occurs in Daqing Oil Field, this article establishes the model of five andnine-spot well pattern by use of Eclipse to forecast cumulative production in the follow-up5years after the well fractured. Meanwhile, this article sets the cumulative production asoptimized goal in optimizing the fracture conductivity and fracture ratio. By means of classifythe diverse formation parameter and put up the numerical simulation separately, afterextensive calculation and result analysis, the optimum fracture ratio and fracture conductivityis obtained under the different formation parameter condition in five and nine-spot wellpattern. The optimized results have definite significance as to the fracture construction workwithin different formation conditions.
