摘要
测井方法是非均质生油岩精细评价的常用方法,但现有的评价方法对生油岩成熟度及密度等因素考虑不全。文中提出了综合考虑生油岩成熟度和各种测井响应的"反推ΔlogR"法,并以Kar7井为例,应用该方法计算了2285～2985m内生油岩的有机碳含量,计算结果与实测值较为吻合,证明了该方法的正确性和可行性。
Logging method is the common method for fine evaluation of heterogeneous source rock. However, a number of factors such as the maturity and density of source rock are not considered completely by existing methods. The ＂Inverse ΔlogR＂ method which considered both the maturity of source rocks and different log responses is proposed, and took Kar 7 well as an example to calculate the organic carbon content of source rocks from 2 285 m to 2 985 m by using this method. The fact that the results are relatively consistent with the measured results proved the exactness and feasibility of this method.
