摘要/Abstract

摘要： 为了提高单井产量、简化流程、降低成本，对S 地区致密砂岩油藏的地质情况进行分析，并借鉴国外致密油成功开发的经验，认为该地区具有储层物性差、裂缝发育及脆性指数高等特征，适合于大排量、大液量及低砂比的体积压裂改造工艺技术。采用的稠化水压裂液体系具有携砂性能高、井筒摩阻低、配液环节简化及综合成本低等特点，经过对22 口井进行现场试验，取得了较好的效果，形成了一种适合鄂尔多斯盆地致密砂岩油藏压裂的配套工艺技术。该技术有效地提高了产量，具有很好的推广应用价值。

Abstract: In order to improve single-well production, simplify workflow and reduce costs, through the analysis of the geological conditions of the tight sandstone reservoir in S area,combined with the foreign experience of successful development of tight oil, it is considered that the reservoir has the characteristics of poor reservoir properties, well developed fractures and high brittleness index, and volume fracturing reconstruction with large displacement, large volume and low sand ratio is suitable for the study area. The thickened water fracturing fluid system has the characteristics of high sand carrying capacity, low wellbore friction, simple liquid preparation and low comprehensive cost. The thickened water fracturing fluid system was used in 22 wells, and good results have been achieved. A set of matching technology was formed for tight sandstone reservoir fracturing in Ordos Basin, which could effectively increase the production and has a good value of application.
