Abstract Geology-engineering integration is an effective way for efficient development of sandy conglome-rate reservoirs, with geomechanical parameters as a bridge. With the sandy conglomerate reservoir of the Upper Urho Formation in the Zhongguai-Ma’nan area of Junggar Basin as an example, key geo-mechanical factors affecting the fracturing effect of the reservoir were analyzed. First, the relationships of rock mechanical parameters of the Urho Formation with the acoustic wave and volume density were studied, which was aimed at revealing the response mechanism of the rock mechanical parameters and building a logging calculation model of the rock mechanical parameters. Based on fracturing and well logging data, a multi-parameter prediction method for formation pore pressure and a calculation model for in-situ stress were develo-ped. Then, the grey correlation method was used to study the correlation degree of geomechanical parameters with the fluid productivity index per meter. It is concluded that the main geomechanical factors affecting the fracturing effect are the horizontal stress difference, brittleness index, elastic modulus, tensile strength, and uniaxial compressive strength in order. Finally, an evaluation model for reservoir fracturing engineering in comprehensive consideration of main geomechanical factors was constructed via the analytic hierarchy process. This research provides a basis for the optimization design of reservoir fracturing in the study area.

Key words： Urho Formation sandy conglomerate reservoir fracturing geomechanical factor
