摘要
Abstract
Since the process of drilling mud filtrate invading formation changes with time, the correlative invasion profile parameters also change with invasion time. So, the responses of high definition induction log (HDIL) change with time too. The dynamic invasion formula based on two-phase percolation theory can calculate formation resistivity profile variations in invasion process, and then, obtained are the variations of apparent resistivity with invasion time of HDIL. Dynamic HDIL responses can provide information both in coordinate and time simultaneously. The coordinate information provides radial responses for six radial depths, and the time information gives the HDIL responses at various time stages. The formation calculation and analysis model shows that the six apparent resistivity responses of HDIL tool arrange with some rules for different invasion time and various reservoirs. When fresh water mud filtrate is used, the apparent resistivity arranges from deeper detective responses to shallower detective responses for oil reservoir, and vice versa for water zone. Whereas the HDIL responses become disorder for both bearing oil and water reservoir because a low resistivity annular in the front of invasion zone effects on the logging data seriously. The present results not only provide the physical understand of invasion characters of new HDIL tool for log analysts, but also are helpful for reservoirs evaluation, determination of the true formation resistivity and initial hydrocarbon saturation.关键词
