[0053] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0054] Step 1: For a certain well area, the seismic data of the well block are collected and processed with high resolution to obtain the characteristics of formation fractures, including fracture distribution information and fracture scale information, and divide the fractures into different grades according to the fracture scale information; 10 meters belong to class I cracks; 1 to 10 meters belong to class II cracks; less than 1 meter belongs to class III cracks;
[0055] Step 2: According to the real drilling data of the block, analyze the vertical depth intervals that are prone to complex situations, and now focus on one of the intervals [1000,1100], specifically as follows figure 2 The risk range and risk space shown;
[0056] Step three: image 3 It is a schematic diagram of the objects to be optimized, different types of comparison...
