Abstract

Abstract

The distribution of longitudinal continuous geostress is of great guiding significance for fracture construction design. Take putaohua reservoir in weixing oil-field as the research object, combined with the actual fracturing data of the reservoirs, the mathematical model of the minimum geostress which is calculated by the continuous logging data is optimized to establish, offering the reasonable continuous geostress profile along the well shaft. Based on the layers of the spontaneous potential curve, getting a value of curves of stress profile and natural gamma according to certain rules, parameters of interlayer thickness, interlayer stress difference and interlayer quality between the to-be fractured layers and on (under) interlayers layers are calculate. the actual fracture design data of the study area are used to avoid the channeling during the fracturing process. This study provides the constraint conditions of the construction parameters of rock formations, such as fracturing displacement, sand filling intensity, liquid quantity per unit thickness and fracturing way. The application of actual experience shows that the conditions can effectively guarantee the success rate of the fracturing technology of mineral exploration and development.
