Abstract:

Based on observation of cores and thin section and property analysis of typical samples, the sedimentary facies of the lower Urho Formation in Ma 2 well block was recognized again, and the development rule and distribution characteristics of favorable reservoirs were studied. The results show that the sedimentary facies of the lower Urho Formation is fan delta which formed as a set of alluvial fan prograded into a lake, not underwater fan deposition, and the sediments generally show an alternate deposition process of tractive current and gravity flow. The sedimentary facies can be divided into 3 subfacies of fan delta plain, fan delta front and predelta, and 10 microfacies of debris flow, sheetflood, stream channel, underwater distributary channel, clastic flow, interdistributay bay, mouth bar, distal bar, prodelta mud and slump, among which debris flow and underwater distributary channel deposition developed very well. The sedimentary microfacies have obvious controlling effect on the reservoir properties and oiliness. The glutenite reservoir developed in the stream channel and underwater distributary channel microfacies is favorable reservoir because of the low content of argillaceous matrix and good reservoir properties. So the glutenite of distributary channel and underwater distributary channel microfacies in each sedimentary period are the first target of oil and gas evaluation and development in the study area in the future.
