A Systematic Approach to Fracture Propagation Simulation with the Integrated Natural Fracture and Geomechanical Model

OnePetroMay, 2023

Abstract In recent years, tight sandstone gas as one of the important types of unconventional resources, has been rapid explored and developed. There are large-scale tight sandstone gas production in Sichuan Basin, Ordos Basin, Bohai Bay Basin, Songliao Basin and other basins, and it has become a key part in the area of increasing gas reserves and production in China. Due to the influence of the reservoir characteristics, tight gas reservoirs have low porosity and permeability, and the tight gas can only be effectively developed by improving the conductivity around the wellbore. Therefore, it is required to perform hydraulic fracturing after the completion of horizontal well drilling to improve the permeability of reservoir. It can be seen that hydraulic fracturing is the core technology for efficient development of tight gas resources. The implementation of hydraulic fracturing scheme directly determines the horizontal well production and EUR. This paper describes the workflow of 3D geomechanical modeling, technical application for Well YQ 3-3-H4 reservoir stimulation treatment, and carries out hydraulic fracture propagation simulation research based on 3D geomechanical model. This paper also compares the micro-seismic data with the simulation results, and the comparison results show that the propagation model is consistent with the micro-seismic monitoring data, which verifies the accuracy of the model. This paper clarifies the distribution law of hydraulic fractures in the three-dimensional space of horizontal wells in YQ 3 block, and the research results can be used to provide guidance and suggestions for the optimization of fracturing design of horizontal wells in tight gas of Sichuan Basin.

Abstract How to realize the efficient development of tight oil reservoir is a key and difficult problem for the unconventional resources of China. To realize the effective development of tight oil reservoir, it is necessary to the reservoir stimulation technology to improve the seepage capacity of low permeability reservoirs and increase the productivity of wells. Reservoir geomechanics is one of the main factors affecting hydraulic fracturing effect. Domestic and foreign experts have conducted a large number of studies on the characteristics of reservoir geomechanics. However, most of them studied the regional geomechanical characteristics based on logging data, lithology characteristics and three-dimensional seismic. Such static geomechanics studies can better reflect the in-situ stress characteristics of reservoirs before hydraulic fracutring but also have limitations and uncertainties in the understanding of regional geomechanical characteristics. Based on the one-dimensional geomechanical study, this paper uses structural characteristics and seismic attributes to study the three-dimensional mechanics spatial distribution characteristics of reservoirs. On this basis, this paper performs dynamic (4D) stress field simulation combined with real-time fracturing treatment and microseismic monitoring data. The research results can be used to guide the design of horizontal wells fracturing design and provide strong technical support for the production capacity construction. This paper studies the static and dynamic geomechanics of Baikou Quan Formation in Da 13 block, Junggar Basin and describes the research methods and processes and applies them to the design and optimization of reservoir stimulation schemes. The research results can help reduce operational costs and improve the efficiency of measures and serves as technical support for the efficient development of tight reservoirs in China.
