The Exhibition Of Sand Body And The Top Management Factors In West Hollow Of Liaohe Oil-Field

The western sag lie in the northeast of Bohai bay. Residuary fields are almost more concealment lithology oil-gas store.In view of this area lothological oil gas pool recognition is a big technology difficult problem, according to geological, the earthquake, the log information synthetic study, applied the new theory, the new technology and the new method of the high resolution sequence stratigraphy, established the high resolution sequence stratum rack, proposed Eocene two sets of sequences, three individuals are the territory, six accurate sequences groups and two biggest flood surface, established three kind of sequences and the system tract depositional mode, applied different system tract deposition evolution pattern forecast the reservoir advantageous brings, and pointed out the different depositions of the sand substance body and the advantageous accumulation brings which are the system tract of sub-area lake and the lake draws back. In this foundation, used the reservoir synthesis inversion the method, namely many elements geologic information unifies on the identical model, realizes each kind of information in the model space organic fusion, enhanced the inversion information amount of use, the information match precision and the inversion result confidence level, the effective forecasts sand substance body distribution and the natural characteristic, clarified the sand substance body space and time to mop with the match relations, studied the high quality reservoir growth host to control the factor, has solved well in the high mature exploration stage, was urgent needs to seek the hiding lothological oil gas pool the difficult problem.
