【摘要】：在油田注水开发过程中,吸水指数是衡量注水井注入效果好坏的重要指标之一。从渗流理论出发,根据油藏工程原理,以五点法井网为例,建立了无因次吸水指数的理论计算公式,并结合矿场实际,确定了喇萨杏油田不同含水阶段理论吸水指数和实际吸水指数的变化规律,其理论计算结果与应用小井距实际资料计算的吸水指数结果一致,表明该方法具有一定的适用性,可以为油田的合理配产、开发调整提供理论依据。
[Abstract]:In the process of oilfield water injection development, the water absorption index is one of the important indexes to evaluate the injection effect of water injection wells. Based on the seepage theory and reservoir engineering principle, the five-point well pattern is taken as an example. The theoretical calculation formula of dimensionless water absorption index is established, and the variation law of theoretical water absorption index and actual water absorption index in different water cut stages of Lasaxing oilfield are determined by combining with the field practice. The result of theoretical calculation is consistent with that of the water absorption index calculated by using the actual data of small well spacing, which indicates that this method has certain applicability and can provide theoretical basis for rational production allocation and development adjustment of oil fields.

【正文快照】： 对于注水开发的油田,注水是油田开发的基础工作。搞好注水工作,不断改善注水效果是扩大注入水在油层中波及体积的关键[1-11]。因此要充分发挥油田在注水开发中的有利因素,改善注水效果,提高油田注水能力,延长油田稳产期,提高油田采收率。吸水指数是在油田注水开发过程中衡量注
