分析高温高压井中温度和地层孔隙压力对钻井液密度的影响

Analysis on the Influence of Temperature and Formation Pore Pressure on the Density of Drilling Fluid in High Temperature and High Pressure Wells

随着我国钻井行业的快速发展,钻井的范围不断扩大,钻井过程经常需要在高温高压环境中进行作业,这就增加了作业难度和作业风险。从大量的施工经验可以看出,在高温高压井中,温度和地层孔隙压力两者都会对钻井液密度造成一定影响,为了确保钻井作业的顺利进行,应当做好相应的分析工作。

With the rapid development of the drilling industry in China, the range of drilling is expanding, and the drilling process often needs to be carried out in high temperature and high pressure environment, which increases the difficulty and risk of operation. From a large number of construction experience, it can be seen that both temperature and formation pore pressure will have a certain influence on the density of drilling fluid in high temperature and high pressure wells. In order to ensure the smooth progress of drilling operation, the corresponding analysis work should be done.
