Binnan Sheet Sand Geological Features And Reservoir Prediction Technology Research

Binnan area sand reservoir development of type 2 are mainly structural and lithologic oil reservoir in order to construct the main reservoir, with the exploration of oil increased in recent years on the sand of the reservoir lithology 2 Exploration has also made a number of successful experiences, such as Bin 671, Bin 672 and foreshore sand 242 2 exploration and development. By pinch Dump on sand control with the formation of the reservoir rock, as well as by dumping sand on pinch faults and plugging common control structures - under Reservoir lithology still further with greater exploration potential, is expected to be Binnan Area under the very important step by one of the reservoir on the middle position. However, due to dumping sand on the stage near the reservoir with pinch single-thickness thin, the limited resolution of seismic data, the reservoir is extremely difficult to describe the urgent need for research studies.The study area sand core paragraph 2 lithology and palaeontological data analysis, combined with sand and the direction of extension of the geological context of the region, identified as 2 sand delta system. At the same time, combined with characteristics of the earthquake, the sand body in the region to determine the major types of sediment dumped on pinch, I like sand, the former plot imbricate, as well as sand lenses. Bin Yugoslavia sheet sand reservoir, the reservoir thickness of the single-thin, horizontal changes in the fast-resolution seismic data is limited, the reservoir is extremely difficult to describe. Therefore, this paper, logging data with high vertical resolution advantage in the earthquake binding on the premise of making full use of logging and rock, and so on single well cycle data and small-division, on the basis of which the completion of the single-phase . Well then, through the establishment of joint profile to identify and phase analysis of the section of the main reservoir in the horizontal changes in order to study the reservoir with sediment distribution.Use of the foreshore area south of the 2 sand case of drilling 300 exploration wells drilled in recent information on the implementation of the statistical analysis Planar sand sandstone distribution characteristics; Seismic technology to optimize the use of property on the foreshore area south of Shahejie the sand flat sandstone reservoirs predicted to be bin Yugoslavia 2 sand reservoir optimization of seismic attributes reservoir prediction map, the more truly reflects the reservoir of the plane distribution Circumstances; use of logging constrained seismic inversion technology, a breakthrough seismic band restrictions, in order to have a wealth of information and a complete high-frequency low-frequency components of the logging data added the limited bandwidth of less than an earthquake, known by the earthquake information and data logging as a constraint , Anti-high-resolution performance of the formation impedance, clear the reservoir of development of vertical and horizontal distribution, forming a reservoir for such a rolling exploration of the technical approach.
