Research And Application Of The Stimulation With Fracturing In Xinzhan-Puxi, Daqing Oil Field

Xinzhan---Puxi of Daqing Oil field is a kind of low permeability and fracture development oil field .Using overall fracturing reformation technique on the block is an efficiency measure. With existing well space, the important thing is to research how to use overall fracture to develop the low permeability oil field with high-efficiency. Through it, we may enhance the oil /water well's ability of stimulation and stimulate injection, enhance the rate of oil production and economic benefits.Based on the further researching of the geological characteristic of reservoir, and according to the reservoir sensitivity and the fracture development status, we ascertain fracture fluid system and prop pant through core testing and on-the-spot testing, and set up a model of the reservoir numerical modeling with fracture, and calculate the influence of the injection and production wells'joint length and conductivity on production index on the condition of existing well pattern and fracture azimuth , and decide rational fracture parameters and the implementation of the plans through comprehensive optimization. We achieved good results by thirty well's formation parameter testing and seventy-nines fracture wells'contrast test. You can use this for reference when taking different fracture designs and techniques on overall fracturing reformation in different blocks and different types of wells in low permeability oil field. It provided scientific basis for efficient production of the low permeability oil field.
