Abstract
The oil reservoirs in the Changqing Oilfield consist of stacked sand/shale deposits, and the majority of the target zones have a<br>permeability of 0.05-0.3mD. All oil wells completed in tight reservoirs from the Changqing Oilfield require fracture<br>stimulation to achieve commercial production and to improve well productivity. Fracture stimulation is also very common for<br>water injection wells to enhance injectivity.
