Correlation between Core, Logging, and Seismic Data at Site 1149 in the Nadezhda Basin

Using a large number of core, logging and seismic data, on the basis of sequence stratigraphy, reservoir geology, sedimentology, such as theory, the San Zhao peripheral zone were studied. FuYu reservoir is studied and Yang DaChengZi reservoir structure of reservoir. Based on coring well cores observation and rock thin section, casting thin sections and scanning electron microscopy (sem) analysis techniques, such as the SQ3–Y1 a sedimentary period main sedimentary, main lithological types, and different oil reservoir is studied.

Sand Bodies

The oil and gas reserves of Gu83 block in Gulong oilfield is very abundant, but the development is very difficult because the sand bodies are thin, scattered and lack of horizontal continuity. Guided by the theory of sequence stratigraphy and reservoir sedimentology, using drilling core, logging and seismic data, the researcher found that the interest area belongs to delta front subfacies deposition, which can be mainly classified by four miscrofacies types including underwater distributary channel, mouth, sheet sand and bay between distributary. The plane distribution of sedimentary microfacies are mainly controlled by the west and north provenance, the two source collected in the middle east of the work area.

Accumulation Characteristics

Based on the sequence stratigraphy principle, reservoir forming elements has been detailed analysis in Cretaceous system of Hailaer basin, by using core, logging and 3-D seismic data. The study shows that the thick mudstone layer in the transgressive systems tract of the super-sequence is good regional source rock .and regional caprock, meanwhile the sandbody developed in transgressive systems tract and highstand systems of the super-sequence become the regional reservoir of depression. The main hydrocarbon migration pathway is uncomformable surface, fault, frame-sandstone, or that the hydrocarbon born in source rock went into the sandstone of sublacustrine fan directly, and then, lithologic reservoirs was formed.

Depositional Systems

Based on the theory of sequence stratigraphy, sequence stratigraphy framework of is established in this paper by comprehensively search of core, logging and 3-D seismic data. Zhalainuoer group in Cano Depression is divided into 5 3rd-order sequences: Sq1、Sq2、Sq3、Sq4、Sq5 from down to up. Based on the division and comparison of sequence formation, the sedimentary facies and the depositional system are proposed to study in the paper, and the main depositional systems are detailed explained. The distribution of these depositional systems is controlled by the sequence framework.
