摘要
随着石油钻井作业自动化技术的发展,钻井液性能自动化测量技术日趋成熟。南海区块储层多为油气共存,储层物性较好,但水层较发育,地层流体侵入钻井液易造成钻井液性能波动较大,导致井下溢流征兆发现不及时。钻井液性能在线监测技术可以实时监控钻井液性能变化情况,结合工程、地质和综合录井信息对井下溢流、地层流体性质进行预判,降低井下事故发生的风险;同时还可以实时监测、全方位采集存储钻井液性能参数数据,便于完井后的查验和对比分析,解决了人工测量不连续、数据记录零散、人为干扰误差、测量数据单一等问题。钻井液性能在线监测技术加快了钻井工程自动化进程,推动了钻井自动化、信息化、智能化的快速发展。
The automatic measurement of drilling fluid properties increasingly mature with the development of automatic drilling technology.The reservoirs in Nanhai Sea block are mostly composed of oil and gas.On the one hand,the reservoir has good physical properties.On the other hand,the water layer is relatively developed,which makes the formation fluid intrude into drilling fluid causing great fluctuation in drilling fluid performance,and cannot find downhole overflow signs in time.The on-line monitoring of drilling fluid performance can monitor the changes of drilling fluid performance in real-time,and predict downhole overflow and formation fluid properties based on engineering,geological and comprehensive logging information,which can reduce the risk of downhole accidents.Meanwhile,the parameters data of drilling fluid performance can be monitored in real-time and comprehensively collected and stored so as to be convenient for the inspection and comparative analysis after well completion.It solves the problems like discontinuous manpower measurement,scattered data records,human interference error,single measurement data and so on.On-line monitoring of drilling fluid performance speeds up the process of drilling automation and promotes the rapid development of drilling automation,intellectualization and informatization.
