“…In the northern Tarim Basin, south to southeasward directed palaeocurrents, as well as detrital zircon U/Pb dating, indicate a sediment source in the Central Tian Shan block and along the southern margin of the South Tian Shan block Peng, 2010). This, associated with the occurrence of Lower Triassic conglomerates in the Early Triassic Ehuobulake Formation of the Kuqa sub-basin (the names of the various sedimentary formations can be found for example in Hendrix et al, 1992, Shao et al, 1999Jin et al, 2008 andQiu et al, 2008), is consistent with the compression-related exhumation phase recognized by the low temperature thermochronology data within the range (Dumitru et al, 2001;Li et al, 2004;. Detrital zircon U/Pb dating in the Middle to Late Triassic along the southern edge of the Junggar Basin (Xiaoquangou Group) indicate a strong widening of the drainage system towards the Central Tian Shan block associated to the progressive erosion of the Permian -Early Triassic topography (Yang et al, 2012).…”

Abstract. The topographic evolution of continents and especially the growth and dismembering of mountain ranges plays a major role in the tectonic evolution of orogenic systems, as well as in regional or global climate changes. A large number of studies have concentrated on the description, quantification and dating of relief building in active mountain ranges. However, deciphering the topographic evolution of a continental area submitted to recurrent tectonic deformation over several hundred millions of years remains a challenge. Here we present a synthesis of the tectonic, geochronological and sedimentological data available on the intracontinental Tian Shan Range to describe its general topographic evolution from Late Palaeozoic to Early Tertiary. We show that this evolution has occurred in two very distinct geodynamic settings, initiating during the Carboniferous in an ocean subduction -continent collision tectonic context before becoming, from Early Permian, purely intra-continental. We show that during most of the Mesozoic, the topography is mostly characterized by a progressive general decrease of the relief. Nonetheless localized, recurrent deformation induced the formation of small-scale reliefs during that period. These deformations were driven by far field effects of possibly several geodynamic processes in a way that still remains to be fully understood.

“…The lithological data of individual strata are derived from wells and published data (Liang et al, 2004;Jin et al, 2008) and are summarised in Table 2. The Lower Jurassic Ahe Formation (J 1 a), Lower Cretaceous (K 1 ) and Lower Paleogene Kumugeliemu Formation (E 1e2 k) are considered as major reservoir rocks in the region with predominant sandstones, formed under braided fluvial, deltaic and lacustrine environments.…”

“…The Lower Cretaceous Bashijiqike sandstones, together with the Paleocene Kumugeliemu Formation evaporates, constitute a well-developed reservoir-cap rock assemblage in the Kuqa depression (Jin et al, 2008). Anticlines related to faults are the main structural traps in the petroleum systems.…”

Depositional and Diagenetic Controls on Pore Structure of Tight Gas Sandstone Reservoirs: Evidence from Lower Cretaceous Bashijiqike Formation in Kelasu Thrust Belts, Kuqa Depression in Tarim Basin of West China

Deeply buried Lower Cretaceous Bashijiqike sandstones are important gas exploration targets in the Kelasu thrust belt, Kuqa Depression of Tarim Basin in China. The sandstones are characterized by low porosity, low permeability and strong microscopic heterogeneity due to diagenesis during their geologic history. Mineralogical, petrographic, and geochemical analyses combined with high-pressure mercury injection analysis have been used to investigate the diagenesis, diagenetic minerals, and their impact on reservoir quality. This article addresses the controls exerted by depositional parameters and diagenetic modifications on pore-network characteristics (porosity, pore types, sizes, shapes, and distribution), with the aim to unravel the formation mechanisms of this complex pore structures, and to improve the characterization and classification evaluation for the Bashijiqike sandstone reservoirs. The Bashijiqike sandstones are dominated by lithic arkoses and feldspathic litharenite. The pore system consists of intergranular macropores, intergranular micropores, and intragranular pores. Framework grains are generally heavily compacted. Authigenic quartz, authigenic feldspar, clay minerals and carbonates are the major pore-filling constituents. The pore structure is characterized by small pore radius and poor interconnectivity. Entry pressure reflects the microscopic pore network and macroscopic reservoir property characteristics. Pore structure characteristics are linked to the depositional parameters, type and degree of diagenesis. Clays do not control reservoir pore networks alone, and pores and pore throats are wider in coarser grained sandstones. Entry pressure decreases with the content of the rigid quartz. Compaction and cementation continue to decrease the pore-throat size, while dissolution enlarges pores and pore-throats radius. Considerable amounts of microporosity associated with clay minerals and altered grains contribute to the high entry pressure. Comprehensive Coefficient of Diagenesis (CCD), which considers the integrative effect of diagenesis, shows strong statistical correlations with entry pressure. CCD is an integrative modulus of diagenesis and physical property, and generally the higher the values are, the better the pore structure. It is suitable for quantitatively characterizing pore structure in tight gas sandstones. The results of this work can help assess pore-network characteristics like the Bashijiqike sandstones which had experienced strong diagenetic modifications during their geological history.
