【摘要】 油水井酸化是油气藏常用的增产增注措施之一。酸化措施是否有效取决于多方面的因素,而选井选层是其中一个重要环节。本文采用模糊物元分析方法,用油水井代表事物,评价因素代表特征,建立了复合模糊物元矩阵,对油田整个区块需要酸化作业的井位和对应层位进行了综合决策,排列出需要进行酸化的井位和层位的先后顺序,为进一步施工奠定了理论基础。该方法排除了人为因素的影响,达到了科学决策的目的。文中选用某油田六口井的实际资料进行了计算,其结果与实际情况一致。更多还原

【Abstract】 Acidification of an oil and water well is one of the measures to increase production and injection. One of its working principles is that. it is an important link for selecting a well or a layer of oil and water. Based on the fuzziness unit method, oil and water well deputy item and the factor evaluating all kinds of deputy characters, a complex fuzziness unit matrix is set up, a comprehensive decision-making is carried out when selecting a well or a layer in an entire block of oil field and the order of well and layer acidification is ranked. It provides a theoretic basis for acidification construction. The method removes any artificial effect on the decision-making concerning acidification and thus can ensure a scientific decision-making process.更多还原
