王宣龙等：利用声波和自然伽马能谱分析泥岩裂缝储层，测井技术，１９９６（６）２０，４３２～４３５。测井资料评价中，由于对泥岩裂缝储层认识不足，常常漏掉这类储层。通过声波时差和自然伽马能谱资料分析泥岩裂缝的储存能力，并利用纯泥岩地层的深度与声波时差的关系，建立相对正常压实趋势线，判断泥岩超压层。利用声波时差定性判断低角度裂缝，从而评价泥岩储层。
Wang Xuanlong et al .: Analysis of mudstone fractured reservoirs using acoustic and gamma ray spectroscopy, Logging Techniques, 1996 (6) 20,432-435. Log data evaluation, due to lack of understanding of shale fractured reservoirs, often miss such reservoirs. The storage capacity of mudstone fractures was analyzed by using acoustic jet lag and gamma ray energy spectrum data. Based on the relationship between the depth of mudstone strata and acoustic jet lag, a relative normal compaction trend line was established to judge mudstone overpressure zone. The low-angle fractures were qualitatively identified by acoustic jet lag to evaluate mudstone reservoirs.
