摘要
为了准确计算断层岩的成岩程度,在考虑了断层岩在上覆地层断面压力作用和成岩作用对断层岩成岩程度影响的基础上,结合断层填充物自身具有的与围岩相似的成岩程度,改进了断层岩成岩程度的计算方法,在对断层岩成岩程度的求取时考虑了断层岩的初始成岩程度,并将其应用在断层侧向古封闭性评价的研究中。
To estimate diagenetic grade of fault rocks more accurately,we,on the basis of considering the sectional pressure of fault rocks in overlying strata and influence of diagenesis on diagenetic grade of fault rocks,are combining diagenetic grade of fault filler that is similar to surrounding rock. We try to improve the calculation method of diagenetic grade of fault rocks on the basis of taking pre-exist Initial diagenetic grade of fault rocks into account,by applying it to fault lateral palaeo sealing.
