Abstract:

The reservoir petrology and sedimentology of lower Minghuazhen Formation(N1m) and Guantao Formation (N1g) were comprehensively studied by detailed core observation, lab experiment data and geophysical data of 3 coring wells in L oilfield in Bohai Bay. The reservoirs are mainly composed of feldspar sandstone. The sandstone of lower N1m is mainly of medium sorting and subangular-subround roundness, while the sandstone of N1g is mainly of poor sorting and subangular roundness. The sandstone developed various sedimentary structures that can reflect river deposition, including low angle cross bedding, trough cross bedding, erosional surfaces and plant roots. Meanwhile, the variegated mudstone deposited also reflects a kind of shallow weak oxidation-reduction and oxidation environment. Accorded to grain size probability cumulative curves, C-M plot and logging characteristics, the lower N1m mainly developed meandering river deposits that can be divided into point bar, channel, abandoned channel, crevasse splay and floodplain microfacies; whereas, the N1g developed braided river deposits that can be divided into channel bar, braided channel, channel margin and interchannel microfacies.
