深水重力流沉积水槽实验研究进展

Flume Experiment Research Progress of Deep Water Gravity Flow

深水重力流沉积一种重要的沉积类型,目前已在全球发现多个深水油气田,可采储量占全球油气新发现储量已达55%,深水重力流沉积已成为油气增储上产的关键目标。目前深水重力流沉积研究主要是基于露头、岩心、测井及地震资料得到的宏观定性认识,缺乏对沉积过程的定量化研究,而水槽实验是深水重力流沉积过程有效的定量化研究手段,为此本文系统总结了深水重力流水槽实验的试验装置,实验流程,以及在深水重力流沉积过程、沉积特征及主控因素方面的应用进展,在此基础上指出水槽实验研究要进一步完善实验参数及限制条件设定,同时要加强多种技术手段的交叉融合,形成各种技术手段优势互补的系统研究方法,有效指导深水油气勘探及开发。

Deep water gravity flow is an important depositional type. At present, lots of deep water oil/gas fields have been discovered all over the world and their recoverable reserves account for 55 percent of the newly discovered oil and gas reserves. So oilfields with deep water gravity flow became key objectives for increasing reserves and production. However, the study of deep water gravity flow is mainly based on outcrop, core, logging and seismic data, so the research results are more qualitative and macroscopic, lack of quantitative cognition. Flume experiment is an effective quantitative method for the study of sedimentary process of deep water gravity flow. So flume experiment equipment and process, sedimentary process, characteristics and the main controlling factors were summarized in the paper, and the paper also pointed out the setting of experimental parameters and limiting conditions should be further improved. In additional, the paper suggested it is necessary to strengthen the integration of various technical means and form a systematic research method with complementary advantages of various technical means, which will effectively guide for deep water oil and gas exploration and development.
