随着近海油气不断开发,其后续发展能力明显不足,因此深水含油气盆地的开发将成为必然的发展趋势。深水油气田的井场调查是深水油气田开发过程中的一个主要环节,其勘探技术越来越被人们所关注。本文通过深水井场调查的技术要求分析,结合多次组织和参加井场调查的工作经验,指出深水油气田井场调查的技术难点在于探索海底表面障碍物分布情况、勘测海底地形地貌特征、了解中浅地层结构等这类勘探技术上。由于这些勘探技术受声呐技术特点的限制,国外已经采用了DEEPTOW、ROV或者AUV技术,将一些关键调查设备与海底保持一定的高度来实现勘探技术目标,并已经取得成功的尝试,因此,研究、发展和不断地完善这类“贴底”调查技术十分重要。
With the continuous development of offshore oil and gas, its follow-up development capability is obviously insufficient. Therefore, the development of deep-water petroliferous basins will become an inevitable development trend. Well-site survey in Sham Shui oil and gas fields is a major part of the development process of deep-water oil and gas fields and its exploration technology has drawn more and more attention. Based on the analysis of the technical requirements of the deepwater wellsite survey and the experience of many times of organizing and participating in wellsite surveys, the paper points out that the technical difficulties in the field investigation of deepwater oil and gas fields lie in exploring the distribution of surface obstructions on the seafloor, surveying the topographic features of the seafloor, Shallow formation and other such exploration technology. As these exploration technologies are limited by the characteristics of sonar technology, DEEPTOW, ROV or AUV technology has been adopted abroad to achieve the exploration technology goal by maintaining some key survey equipment and the seafloor height. At the same time, successful attempts have been made to study, It is important to develop and continually refine such “touchdown” research techniques.
