Abstract
At present, the mainstream technology for the stimulation of tight reservoir which exists a large number of interlayer is "perforation concentrated & large-scale fracturing". But the fracture simulation and monitoring result indicates that the vertical zone of the reservoir actually isn't stimulated fully. To increase the degree of the reservoir stimulated, the stimulation mechanism of dynamic multistage temporary plugging fracturing, temporary plugging agent and technological parameter have been studied. By optimizing the combination of temporary plugging materials, dosage, construction parameters and adding speed, the temporary plugging material has stable performance, has played a good role in temporary plugging and boosting pressure in field tests. The critical technique which is characterized by "multi-cluster perforation, temporary plugging near wellbore and multistage fracturing" is developed, and the design concept of dynamic multi-stage temporary plugging fracturing pump injection is defined. The production of the test well is twice as the neighboring well, in addition, it can realize multistage fracturing in single operation to decrease the fracturing cost, which makes the technique a promising future.
