【摘要】：随着油田勘探开发的深入,发现的油层类型和储层结构越来越复杂,如何解决复杂油层勘探开发的增产问题就成为油田成功勘探开发的关键技术瓶颈,特别是近年来勘探开发遇到的底水油帽油层、薄互层以及低丰度巨厚砂体油层,如何有效的进行增产改造，有效解放油层使其最大限度的释放储层产能,取得较大的勘探开发效果,通过广泛调研和论证认为引进目前较为前沿的水力喷射压裂新工艺进行先导性试验和研究、是切实可行最新增产压裂工艺技术。本论文通过对水力喷射压裂工艺的发展状况、适用条件做了详细的论述,同时对其技术基本机理、裂技术特点及施工工艺等做了系统研究和分析,并根据鄂尔多斯盆地富黄探区油层条件对压裂液配方进行调整和优化。针对富黄探区实际情况,选择了10口井进行水力喷射压裂工艺现场试验,通过现场试验取得了比较理想的效果。
[Abstract]:With the development of oilfield exploration and development, the types of reservoir and reservoir structure are becoming more and more complex. How to solve the problem of increasing production of oil exploration and development in complex reservoir becomes the key technical bottleneck of successful exploration and development of oil field. Especially, in recent years, the bottom water cap reservoir, thin interbed layer and low abundance and huge thick sand body reservoir encountered in the exploration and development, how to effectively increase production and transform, effectively liberate the reservoir to maximize the release of reservoir productivity, Through extensive investigation and argumentation, it is considered that it is the latest practical and feasible fracturing technology to introduce the new hydraulic jet fracturing technology, which is currently in the forefront, for pilot test and research. In this paper, the development of hydraulic jet fracturing technology and its applicable conditions are discussed in detail. At the same time, the basic mechanism of the technology, the characteristics of fracture technology and the construction technology are systematically studied and analyzed. The formula of fracturing fluid was adjusted and optimized according to the reservoir conditions in the Huang-rich exploration area of Ordos Basin. In view of the actual situation in the Yellow River rich exploration area, 10 wells were selected for field test of hydraulic jet fracturing process, and satisfactory results were obtained through the field test.
