Description

棋盘格式可视化水力裂缝模拟装置
技术领域
本发明属于油气田开发研究技术领域,具体涉及一种棋盘格式可视化水力裂缝模拟装置。
背景技术
在水力压裂中,支撑剂在裂缝中铺置的情况对作业的成功起着至关重要的作用。在压裂过程中,混砂液经泵的输送进入裂缝中,支撑剂在重力、浮力、水平方向液体携带力、粘滞阻力的影响下,在裂缝的垂直剖面上存在浓度差别,自上而下可分为无砂区、悬浮区、颗粒滚流区、砂堤。现场施工时,支撑剂可能会全部沉降至裂缝底部,导致裂缝上部无支撑剂充填,从而形成无效的裂缝支撑,这样严重影响了裂缝的导流能力和压裂的增产效果。因此对支撑剂运移及铺置情况的准确预测是设计和评价水力压裂措施的关键所在。
现有技术中,只能模拟单一直缝,无法有效反映支撑剂在壁面摩擦、曲折裂缝及缝网的运移及铺置规律。
发明内容
本发明的目的之一在于克服现有技术的缺陷,针对现有技术中只能模拟单一直缝无法模拟曲折裂缝、缝网的情况而设计,公开一种棋盘格式可视化水力裂缝模拟装置,该装置可以模拟多种裂缝的走向、角度,以及模拟体积压裂形成的裂缝、缝网,并有效反映支撑剂在曲折裂缝及缝网的运移及铺置规律。
本发明提供一种棋盘格式可视化水力裂缝模拟装置,包括九宫格型底盘和平板,所述九宫格型底盘带有卡槽,所述平板为透明玻璃平板,卡槽轨迹交汇处的节点上均配备八通连通器,卡槽上安置平板。
所述节点外有卡槽,用于固定平板并密封。
所述平板具有渗流孔。
本发明的有益效果在于,本发明可通过平板安插在九宫格型底盘卡槽或者节点处的八通连通器上的不同组合,模拟多种裂缝走向、角度,以及模拟体积压裂形成的裂缝、缝网,并有效反映支撑剂在曲折裂缝及缝网的运移及铺置规律。
下面结合附图和实施例对本发明作进一步说明。
