在调研分析国内外堵水调剖的经验教训的基础上，按照系统工程认真地组织了这个研究试验项目。首先，从油藏描述搞清沉积相和剩余油分布入手，经过油藏数值模拟、历史拟合、注示踪剂等技术的应用，加深了对油藏分层静动态的认识，经过系统室内试验，研究筛选出廉价的粘土颗粒堵剂，建立了优化设计方法，得出最佳方案，确定了适应大剂量封堵大孔道的多段塞双液法施工程序，因地制宜地配套了立式电泵堵水工艺，进行了科学的效果综合评价，形成了封堵大孔道控水稳油的配套技术。该技术研究了粘土的各项性能，封堵机理，与其配套的技术结合起来，经现场341口井试验，效果明显，增油36×104余t，为石油企业提供了一条改善高渗透油田开发效果的新途径，将对油田控水稳油起到重要的作用。本文主要介绍了胜坨油田二区沙二3整体封堵大孔道控水稳油技术。
Based on the investigation and analysis of the experiences and lessons of plugging and profile control at home and abroad, this research project was carefully organized according to the system engineering. First of all, starting from the description of the reservoir, it starts with the distribution of sedimentary facies and residual oil. After the application of reservoir numerical simulation, historical fitting and tracer technology, the understanding of stratified static and dynamic state of reservoir is deepened. After the system indoor Test, research screening of cheap clay particle plugging agent, the establishment of optimal design methods, come to the best solution to determine the large plug to block the large multistage plug two-liquid construction method, according to local conditions to support a vertical electric pump Water blocking technology, a comprehensive evaluation of the effect of science, blocking the formation of a large hole water control oil stable technology. The technology of the clay properties, sealing mechanism, combined with its supporting technology, the field test of 341 wells, the effect is obvious, oil more than 36 × 104 Yu t, for the oil companies to provide an improved high permeability oilfield development The new way of effect will play an important role in stabilizing the water in the oilfield. This paper mainly introduces the overall plugging of macropore channel water-stabilizing oil technology in Sha 2 oil field in Shengtuo Oilfield.
