Abstract
In order to improve the recovery rate of tight glutenite horizontal wells in the Baikouquan Formation in Mahu Sag, geological models were constructed through three aspects: structural modeling, lithofacies modeling, and attribute modeling; through rock mechanics parameters, in-situ stress direction, and vertical direction. Stress, pore fluid pressure, maximum horizontal principal stress, minimum horizontal principal stress to construct a one-dimensional in-situ stress model, combined with imaging logging wellbore wall caving and induced fractures to determine the in-situ stress direction to simulate the three-dimensional stress direction in the study area, using finite element method to simulate and The objective function fits and inverses the distribution of the three-dimensional in-situ stress field. Finally, comprehensive reservoir parameter characteristics and engineering parameter characteristics are used to predict the “sweet spot” of the study area. The results show that there are three types of sweet spots in the glutenite in the Mahu Depression: Type I sweet spots are good reservoirs with good oil content, high oil well production, and good reservoir engineering compressibility; Type II sweet spots are followed by oiliness and oil well production; Type III The sweet reservoirs have just reached the lower limit of the oil layer standard, mainly poor oil layers. The research results provide a reference for the development of Baikouquan tight glutenite in Mahu Sag.
