摘要：
Strike-slip faults play an important role in controlling hydrocarbon accumulation. In order to investigate the effect of strike-slip faults on the Sinian-Cambrian hydrocarbon accumulation in the Gaoshiti-Moxi area of Sichuan basin, seismic interpretation of strike-slip faults and systematic fluid inclusion analysis of diagenetic minerals filled in solution vugs were carried out, and the active stages of strike-slip faults and the hydrocarbon accumulation orders were determined. Moreover, the coupling relationship between strike-slip fault active stages and the hydrocarbon accumulation orders were discussed, and established a “floor type”hydrocarbon accumulation model controlled by strike-slip fault. Under this model, there are multiple sets of high-quality reservoirs developed vertically, which are shown as multi-layer systems containing oil and gas, and the oil and gas accumulation characteristics of each layer system are highly similar. For the areas where there is a“floor type”oil and gas accumulation mode, attention should be paid to three-dimensional exploration. © 2023 China University of Geosciences. All rights reserved.
