The case calculation indicates that the radial flow model can reflect the behavior of cold production and sand inflow , be consistent with real situations quantitatively , and prove its reliable property 此外,实例计算还表明,连续出砂确实是出砂冷采提高产量的重要机理之一。
The cold heavy oil production ( chop ) technology can be applied to form in - situ high permeable channels by mass sand inflow and allow the heavy oil to be produced by means of foam - oil effects 而稠油出砂冷采技术通过大量出砂形成高渗流通道,并借助于泡沫油的作用等机理来开采稠油油藏,可以较好地解决热采中遇到的问题。
The study also shows that continuous sand inflow is indeed one of the most key mechanisms by chop for ior , such as forming highly flowing channels , removing skin effect and improving fluid flowing performance in have oil reservoir 地层连续出砂使得井筒附近形成高渗流通道,解除了表皮污染,改善了油藏中流体的流动特性。
