“…Massive efforts have been devoted to karst research of Ordovician carbonate rocks in Tahe oilfield for a long time, the achievements are rich, including: (a) the research of Tarim Basin and a wider range, such as stratigraphy (Wang 1999), sedimentology (Sun 2001), structural geology and geotectonic (Lee 1955), oil and gas exploration area (Dai et al;Jin et al 2017;Jia et al 2013), structural system oil-control model (Yuzhu 2018), structure and hydrocarbon distribution (Sun et al 2002) and reservoir characteristics (Sun et al 2020); (b) the academic contributions of Akekule uplift, such as structural characteristics (Li 2006), fault characteristics (Ji et al 2008), paleo-tectonic restoration (He et al 2011), reservoir tectonic stress field (Ding et al 2009;Liu et al 2020), tectonic evolution (Ren et al 2008;Feng 2012;Wu 2013), the influence of tectonic movement on carbonate rocks (Yu and Fu 2006), etc. In addition, there are related studies on some areas or structural belts in Tarim Basin (Sun et al 2019a;Luo et al 2012;Wu et al 2012); (c) the field investigation of karst phenomena in outcrop area of northern Tarim basin, involving of characteristics of paleo-karst (Liu et al 2013a;Gao et al 2014), karst cave system (Shi et al 2014), controlling factors of paleo-karst cave (Li et al 2013), characteristics of karst collapse body (Liu and Cai 2010), karst zonation (Feng et al 2010), development model of paleo-karst (Zhang et al 2013), outcrop characterization of paleo-karst reservoir , vertical fracture-controlled development model (Liu et al 2011), etc.…”
