Based on our company's major science and technology ceramic proppant projects "oil recovery and downhole operation of new technology, new equipment research and field test" task "efficient pulse fracturing technology integration and test," Igawa Downhole drilling company continued research, with self-developed pulse fracturing Indoor engineering simulation evaluation test system as a platform for the continuous support not fracture conductivity, fracture proppant pulsincap flow stability, fiber hanging sand and separate effects a study.
The test results show that the non-continuous manner sanding artificial fractures can result in more support continuous support crack about two orders of magnitude higher fracture conductivity. At the same time, the adoption of effective partition proppant sand under pulsed conditions of stability and slug plug between the fibers suspended sand can carry out. Combining theoretical models and field tests, the researchers also explored the pulse time, proppant sand column stability control, optimization of the ratio ceramic proppant manufacturers of the concentration of fibers and sand fracturing and other key technologies, initially formed a pulsed sand fracturing technology, liquid and material systems, integrated package of special equipment, basically a pulsed sand fracturing technology of autonomy.
