Reservior Character Study Of Xing'anling Group About Beil4 Block In Sudeerte

According to geological,seismic and logging well data of Beier hollow in Hailaer basin,this thesis takes sequence stratigraphy, sedimentlogy, petroleum geology etc theories as itsinstrument and take three dimensional seismic explanation technology, high resolution seismicinversion technology, the sedimentary facies analysis technology, depositional facies analysistechnology, oil-gas layer comprehensive evaluation technology as its Support. The study ofreservoir characteristic research has been carried out in six aspects, including the structure faultcharacteristic research, the structural history research, the high resolution sequencestratigraphy research, the sedimentary facies characteristic research, the reservoir inversion andthe natural characteristic research and the oil-gas pool synthesis, suitable methods ofcharacteristic description for this area have been summarized. Main achievement includes: (1) take the sequence stratigraphy theory as the instruction divided and compared to stratain entire area, the high resolution sequence stratigraphy frame and three series of tertiarysequence have been established by the numbers, MSC1 in the region is set of complete tertiarysequence, MSC2 is only grows the HST, MSC3 is only grows the TST. (2)the distribution of each oil layer top is a fault nose structure to NNE direction ,which iscomplicated by drape and fault, and rupture is complex. The whole pattern is that the middle ishigh and the entourage is low. (3)Bei14 fault blocks trap formed the time after Xing'anling Group deposition beforeNantun formation deposition, and the B184 number fault in south controled sediment of thisarea. (4) Xing'anling Group oil in Bei 14 areas is carried on the reservoir inversion using thesimulation anneal method, from that, it can identify three sets of reservoirs from the inversionsection plane, the result is that III oil layers is best, and the connectivity is good, sand bodygradually attenuates along the south or eastsouth direction of source to northwest. (5) Used core, well logging and seismic data to determine this area is fan delta depositionsystem which the fault of controlling sediment in eastsouth has an effect on, and the sourcedirection is eastsouth. (6)In reservoir aspect, the oil source is sufficient in the study region, which betweeneastern side of main hydrocarbon hollow trough in the northwest of Beier and deep big faultcrossing segment;the reservoir mainly develops sandstone and the gritstone sub-faciesdeposition of the front fan delta. Petrophisical is bad, the reservoir bearing oil type mainly isfault anticline oil pool and the lithological character-structural oil pool. (7)In the oil-water distribution rule aspect, the liquid is no water but oil, so it has nouniform water-oil interface.Sandstone is more expedite, and oil is better in good reservoir. Atlast we bring forward avail target on study of synthesis analyse.Key words: Bei14 block reservoir character Xing'anling Group sequence stratum...
