    I. Geophysical exploration technology

    1. Seismic data interpretation technology

    Implement horizon calibration, horizon interpretation, velocity determination and validity analysis of mapping and trap through using seismic data interpretation system. Besides, put structural and fracture characteristics of study area into practice, divide tectonic units, look for structural traps and describe complex fault block and fault development condition.

    2. Inverting reservoir prediction technology

    Carry out multi-attribute inversion, post-stack stochastic inversion and pre-stack inversion and predict space distribution characteristics of the reservoir through using seismic data, combining geological law of the region and taking drilling and logging data as constraint. 

    3. Fluid detection technology

    Implement recognition study of reservoir fluid in two-phase medium, identify true and false bright spot and detect reservoir fluid property through analysis of dynamic characteristics of seismic record.

    4. Fracture prediction technology

    Calculate dependent variable of the formation caused by tectonic movement through implementing inversion and forward of structural history of the formation. Besides, predict main development direction and development concentration area of the fracture through combining parameters such as formation thickness, lithology and development direction of the fracture.

    II. Geological study technology of oil and gas field

    1. Logging interpretation technology

    Primary logging interpretation: Create logging interpretation template, divide reservoir and non-reservoir, interpret reservoir physical property and oil-bearing properties and provide basis for testing and optimizing commissioning horizon according to the data such as the core and the test.

    Secondary logging interpretation: Re-recognize physical property and fluid property of the reservoir, define the relation among oil, gas and water in oil and gas reservoir and implement all parameters required for reserve verification according to the data such as the core, the test and production. 

    Use rock mechanics parameters to calculate stress direction, poisson ratio and young modulus and provide basis to fracturing design and construction.

    2. Reserves evaluation technology

    Carry out reserves calculation for the basin, the zone and the trap according to the data obtained in different exploration stages. Besides, submit results of reserves calculation at different levels according to division standard of different reserves.

    3. Oil (Gas) reservoir description and geological modeling technology

    Implement stratigraphic correlation and subdivision and basic characteristics study of oil and gas reservoir including structural characteristics, reservoir distribution characteristics, sedimentary (micro) facies, fluid distribution law and temperature-pressure system; carry out (fine) description of oil reservoir and geological modeling study for data obtained in different development stages and production requirement.

    III. Oil and gas field development technology

    1. Reservoir dynamic analysis technology

    Know fluid seepage law and production characteristics in oil reservoir, propose modification measures for oil reservoir and improve productivity of single well/oilfield through analysis of well testing and early production test, static and production and monitoring data. 

    2. Reservoir numerical simulation technology

    Reproduce production process of oil and gas reservoir through reservoir numerical simulation. Besides, analyze principal contradiction existing in development, study remaining oil distribution law and provide basis for formulating adjustment scheme and predict and optimize all development technical limits and indicators.
