高温吞吐或高温蒸汽地层,在高温蒸汽的冲刷和热膨胀的作用下,地层胶结物被破坏,这样砂粒就会和油一起流出来,而随着油田的含水量、采油量不断增加,油层结构被破坏的越来越严重,这一问题越来越明显。砂粒不断增加,这样不仅影响了产油的质量,更影响了出油的速度,导致油井无法正常生产,所以不得不采取可靠的防砂技术措施。本文对现在研制的六种蒸汽吞吐井地层稳定封窜剂进行分析,力求寻找到一种具备抗压强、耐高温、成本低等优点的蒸汽吞吐井地层稳定封窜剂,从而提高我国稠油的出油率。 High-temperature huff or high-temperature steam formation, under the action of high-temperature steam erosion and thermal expansion, the formation cement is destroyed, so sand will flow out with the oil, and with the oil field water content, oil production continues to increase, the oil layer structure is The problem of getting worse and worsened becomes more and more obvious. Grit continues to increase, this not only affects the quality of oil production, but also affect the speed of oil, resulting in normal production wells, so had to take reliable sand control technology and measures. In this paper, six kinds of steam huff and puff wells are developed to analyze the stability of the sealing agent, and aiming to find a stable sealing agent for the steam stimulation well with the advantages of high pressure resistance, high temperature resistance and low cost, The oil rate.
