摘要
水深超过500m的深水海域所蕴藏的油气资源是非常诱人的,进一步开发利用深水油气资源大势所趋。但深水所带来的低温、地层破裂压力低、浅层流体流动和高昂的深水钻井装置费用等问题又提出了严峻的挑战。通过对深水注水泥温度确定、低密度水泥浆稳定性、流变性、胶凝强度、候凝时间、水泥石具有的机械力学性能等一系列的特殊要求分析,提出了以准确预测深水注水泥温度为前提,以深水固井材料体系研究为基础,以新型钻井液固井液一体化技术为方向,以深水固井时可能存在的风险为指导,有针对性地优化深水固井水泥浆的性能和注水泥工艺,以有效解决深水固井中所面临的困难。
The hydrocarbon resources in deepwater areas, where water depths in excess of 500 m, are attractive. The trend of developing and utilizing the hydrocarbon resources is necessary. Unfortunately, the factors of influencing deepwater cementing, for example, low temperature, low fracturing pressure, shallow water and gas flow and highly day rate for deepwater rigs, make us lots of critical challenges. In order to efficiently resolve these problems, it is suggested to aim to optimize the properties of deepwater cement slurry and the technology of deepwater cementing by analyzing the special requirements such as temperatures for deepwater cementing, stability of low density cement slurry, rheology, static gel strength, curing time and mechanical properties of the cement. The prerequisite is the prediction temperature for deepwater cementing. The base is a material system researches for deepwater cementing. The research direction is the integrated technology of drilling fluid and cement slurry.
