The Strike-Slip Fault Effects on Tight Ordovician Reef-Shoal Reservoirs in the Central Tarim Basin (NW China)

The largest carbonate condensate field in China has been found the central Tarim Basin. Ordovician reservoirs are generally attributed to reef-shoal microfacies along a platform margin. However, recent production success achieved NE-trending strike-slip fault zones that intersect at For this contribution, we analyzed effects on by using new geological, geophysical, and data. Seismic data shows some faults intersected NW-trending margin multiple segments. research indicated development of affected prepositional landforms subsequent segmentation varied In addition, compartmentalized into segments extent We show fractured complexes favorable for dissolution porosity damage zones. tight matrix (porosity < 6%, permeability 0.5 mD), could be increased more than 2–5 times 1–2 orders magnitude zone, respectively. This suggests high wells correlated with “sweet spots” zones, proximity activity might major target commercial exploitation deep carbonates.
