From the developping experience of the low permeability reservoir with preliminary injection in the past two years, we got a very positive results。First, on 下载后可任意编辑the base of the study to the charactors of the reservoir, choose a suitable well pattern, and take a overall fracturing to the oil zones in order to get a good oil producing rate at the beginning. Then, inspect the changing of the parameters to reflect the situation of the reservoir and analyse the productin changing ,to adjust the injection program accordingly ,to keep the balance between the producing and injection. After 18 months’developping, Compare to the blocks that was injected after a period of producing, the producing rate for a single well on average in the block that was injected before the p...
