海洋钻探钻井液循环技术

Offshore drilling fluid circulation technology

摘要:

在海洋钻探过程中，钻井液循环方式一直备受关注，在海洋环境保护法和HSE的要求下合理选择钻井液循环技术方法是钻探工程师必须要考虑的问题。本文介绍了浅水钻探、深水钻探钻井液循环技术的发展历史和技术现状，其中包括石油套管循环、双层套管循环、隔水导管循环、隔水管循环、无隔水管循环（RMR）、反循环（RDM）、水力反循环（HRC）以及气举反循环技术，分析了钻井液循环技术的装备结构、施工工艺以及工作原理，提出了海岸工程、近海工程以及深水油气、矿产资源的勘查开发对不同钻井液循环技术的市场和技术需求，以及该类技术在大洋科学钻探中应用的可能性。

Abstract:

The drilling fluid circulation mode has always been concerned in offshore drilling. Under the requirements of the marine environmental protection law and HSE, the reasonable selection of drilling fluid circulation technology must be considered by drilling engineers. This paper introduces the development history and present status of drillingfluid circulation technology in shallow and deep ocean drilling including Oil Casing Circulation, Double CasingCirculation, Conductor Circulation, Riser Circulation, Riserless Mud Recovery System, ReelWell Drilling Method, Hydraulic Reverse Circulation and Gas Reverse Circulation technology. Analysis is made of the equipment structure, construction process and working principle of drilling fluid circulation technology. The market and technicalrequirements of coastal engineering, offshore engineering and exploration and development of deep-water oil, gas and mineral resources on different drilling fluid circulation technologies are put forward with the possibility of application of such technologies in ocean scientific drilling.
