摘要
亲子互动对油气页岩生产商构成了严峻挑战(Roussel et al., 2013;Yaich et al., 2014;Rimedio等,2015;Miller et al., 2016;King et al., 2017;Dhuldhoya and Dusterhoft, 2017;Cipolla等人,2018;Whitfield et al., 2018;Rainbolt and Esco, 2018;Lindsay等人,2018;Gale et al., 2018;Scherz等人,2019;郭等人,2019;Jin and Zoback, 2019;Kumar et al., 2020;郑等,2020;Gupta et al., 2020)。该行业在了解原因和缓解措施方面取得了重大进展。然而,重要的不确定性依然存在。裂缝驱动的相互作用,或者更常见的“裂缝冲击”,在不同的盆地表现出不同的行为。在大多数盆地中,母井在压裂后会出现产量损失。我们研究并对比了Bakken地区的一个案例研究,该地区的产量上升与俄克拉荷马州STACK案例研究中对产量损失的观察结果。在Bakken的案例研究中,我们发现产能的提高是由支撑剂运输和裂缝导流能力的扩大所驱动的,没有明显的表皮或导流能力受损。这表明,在没有特定破坏机制的情况下,压裂冲击可以通过加压和增加支撑面积来提高产能。在STACK案例研究中,为了匹配历史数据,必须引入裂缝导电性损伤反应。这表明,在STACK,也许还有其他盆地,在压裂击中后,地下正在发生其他过程,以阻碍油井的产能。我们假设不同盆地的矿物学、岩石物理和储层条件的差异导致裂缝驱动相互作用的影响不同。
Modeling Frac Hits: Mechanisms for Damage Versus Uplift
Parent/child interactions pose a critical challenge for oil and gas shale producers (Roussel et al., 2013; Yaich et al., 2014; Rimedio et al., 2015; Miller et al., 2016; King et al., 2017; Dhuldhoya and Dusterhoft, 2017; Cipolla et al., 2018; Whitfield et al., 2018; Rainbolt and Esco, 2018; Lindsay et al., 2018; Gale et al., 2018; Scherz et al., 2019; Guo et al., 2019; Jin and Zoback, 2019; Kumar et al., 2020; Zheng et al., 2020; Gupta et al., 2020). The industry has progressed significantly in its understanding of causes and mitigation. However, important uncertainties remain. Fracture driven interactions or more commonly, "frac hits", exhibit varied behaviors in different basins. In the majority of basins, parent wells exhibit production loses after a frac hit. We examine and contrast a case study in the Bakken where production uplift occurs to observations of production loss in a STACK case study in Oklahoma. We show the productivity enhancement in the Bakken case study is driven by proppant transport and fracture conductivity amplification, with no apparent skin or conductivity damage. This suggests that absent specific damage mechanisms, frac hits alone can improve productivity via repressurization and increased propped area. In the STACK case study, fracture conductivity damage reactions must be introduced in order to match the historical data. This suggests that in the STACK, and perhaps other basins, additional processes are occurring in the subsurface to hinder the productivity of wells after frac hits. We postulate that minerology, petrophysics, and reservoir condition differences between basins causes differences in impacts of the fracture driven interactions.
