    Abstract
  • The frequent leakage and large loss of drilling fluid during drilling in Bozi area of Tarim Oilfield have caused huge economic losses, which is a major difficulty in exploration and development in this area at present. The existing traditional fracture plugging simulation method is difficult to simulate the downhole fracture conditions, resulting in a large difference between the indoor experimental results and the field application. Taking the Bozi area as an example, through the analysis of its reservoir characteristics, it is clear that the reservoir leakage is caused by natural fracture leakage and weak formation fracture; Based on 3D scanning and printing technology, a simulation fracture plate with real fracture characteristics of the reservoir is made, and a new method of fracture plugging simulation is established with this as the core. The evaluation experiment of plugging formula under different fracture widths is carried out using self-developed plugging instrument. The experimental results show that the new method of fracture plugging simulation is applicable to the simulation and evaluation of the plugging formula in multi-scale fractured formations, and can provide strong support for the on-site testing of the plugging formula for fracture loss.
