流场重整提高采收率技术研究
RESEARCHES ON THE EOR TECHNIQUE BY FLOW FIELD REARRANGEMENT
摘要
Abstract
After entering into the high water-cut stage of an oil fields, the reservoir parameters will change, and more seriously the domain channels will be formed between producers and injectors, thus the used ratio of the injected water will be lowered, so the understandings evaluation and flow field rearrangement and the domain field determination can enhance the oil recovery. The pore radius, water flooded PV, water cut and fluid velocity are chosen as evaluating indexes and furthermore by means of AHP (analytical hierarchy process) and fuzzy comprehensive e-valuation method, the evaluating system for the oil reservoir are established. At the meantime, the system is applied in Chengdong Block, the domain flow fields of the main series of strata ( Ng251 , Ng252, Ng331 , Ng332, Ng3 ) are found larger. According to the principles of flow field rearrangement, the following adjustments such as well pattern, series of the strata and production system are implemented. The numerical simulaLion of the streamline show that after the rearrangement of the flow fields the total field strength can be lowered, the usage ratio of the injected water has been enhanced, thus the effectiveness of the system is proven and furthermore the achievements a-bove can provide decision-making evidences for high water-cut oilfield adjustment.关键词
