Abstract

Abstract:

The Mesozoic reservoir in the Jiyang Depression， Bohai Bay Basin， is taken to solve the following problems faced by petroleum exploration， including lithology， diagenetic types， reservoir space， quality-controlling factors of weathering crust reservoirs， through core and thin section observation， as well as other means of lab analysis. Eventually， a multivariate reserve-controlling model is established to provide geological evidence for weathering crust reservoir exploration and development in the Jiyang Depression together with other continental basins in China. The results show that there are 12 types of rock in 5 categories in the Mesozoic weathering crust reservoir in the Jiyang Depression， including terrigenous clastic rock， pyroclastic rock， volcanic lava， subvolcanic rock and plutonic intrusive rock， among which the clastic rock reservoir is of the best with higher initial porosity. The dissolution of meteoric fresh water and organic acids serves to significantly improve the clastic reservoir quality. Gas spillage， condensation shrinkage， high-temperature and acid water dissolution are of constructive value to igneous reservoir quality. Clastic reservoirs are largely affected by compositional maturity， compaction strength， early calcite cementation and organic acid reformation during secondary burial. Secondary dissolution pores serve as the main reservoir space. The quality of weathering crust reservoir in the study area is comprehensively affected by many factors， such as lithology and lithofacies， diagenetic fluid， tectonic evolution， and present burial depth， etc.； therefore a five-element reservoir-controlling model is proposed. The development model of the Mesozoic reservoir sweet spots is established， by which the favorable reservoirs can be grouped into five types， that is， fault and unconformity window dissolution zone， residual leaching zone after cementation， residual leaching zone following denudation， mixed dissolution zone and favorable lithofacies juxtaposition zone.

Key words: diagenesis, reservoir quality, sweet spot model, weathering crust reservoir, Mesozoic, Jiyang Depression, Bohai Bay Basin
