【摘要】：大庆杏树岗油田杏六区开发已经进入了特高含水期,目前油田面临剩余可采储量有限、剩余油分布高度分散、地质情况复杂、开发难度加大、产量递减迅速等世界级开发难题,历经数年的水驱后,油田层系间三大矛盾凸显、注采关系复杂、挖潜效果很差,因此,如何有效的平衡上述矛盾,解决上述问题,为油田持续增产稳产、制定科学合理可持续的发展策略,已经成为现在高含水后期油田面临的普遍问题。本文以大庆杏树岗油田杏六区为研究对象,对该区块的地质特征,储层特征,开发现状,剩余油潜力,区块存在的主要问题及矛盾进行了分析评价。首先整理分析了杏六区不同增产措施后的油水井数据,从油水井压裂、油井补孔、油井堵水、水井酸化等方面进行具体的增产措施效果分析评价,为了知道增产各影响因素与日增油量之间的关联程度,本论文采用单因素分析法、灰色关联法以及人工神经网络法以压裂井例,对各因素进行了关联性评价。对杏六区油田开发评价具有一定指导意义。
[Abstract]:The development of Xingshugang Oilfield in Daqing Xingshugang Oilfield has entered an extremely high water-cut period. At present, the oilfield is faced with world-class development problems such as limited remaining recoverable reserves, highly dispersed remaining oil distribution, complex geological conditions, increased difficulty in development and rapid decline in production. After several years of water flooding, the three major contradictions between layers in oil fields are prominent, the relationship between injection and production is complex, and the effect of tapping potential is very poor. Therefore, how to effectively balance the above contradictions and solve the above problems in order to increase production and stabilize production continuously, Making scientific, reasonable and sustainable development strategy has become a common problem in the later stage of high water cut oilfield. This paper takes Xingshugang oilfield as the research object, and gives the geological characteristics, reservoir characteristics and development status of the block. The remaining oil potential, the main problems and contradictions existing in the block are analyzed and evaluated. Firstly, the data of oil and water wells after different measures of increasing production are analyzed and analyzed, including fracturing of oil and water wells, filling holes in oil wells, water shutoff in wells, etc. In order to know the correlation between the influence factors of increasing production and daily oil production, the single factor analysis method is used in this paper. The grey correlation method and artificial neural network method are used to evaluate the correlation of various factors with the example of fracturing wells, which has a certain guiding significance for the development evaluation of Xingliu Oilfield.
