钻进过程中地层压力跟踪监测与评价
FOLLOW-UP MONITORING AND EVALUATION OF THE FORMATION PRESSURE IN THE PRO CESS OF DRILLING
摘要
Abstract
In Sichuan basin, especially in East Sichuan region, the multiple pay beds and multiple pressure systems are common longitudinally and the high pressure and low one are al ternative, which generally causes the complexity in borehole, prolongs the drilling cycle and increases the drilling cost. For this reason, utlizing the function of logging while drilling with combination logging tool to conduct the follow-up monitoring and evaluation of the carbonate formation pressure in the process of drilling to evaluate thus the main target zone and the reser voirs above the target zone is of a very important practical sig nificance for the drilling engineering decision (making drill stem test or not, selecting the density of the drilling fluid and drilling measures for following drilling and adopting casing off or not to change casing program, etc. ) and completing the drilling with safety and high quality and effidency.关键词
