| titleOfInvention | Deep river sand body oil gas detection method based on de-compaction effect |
| abstract | The invention provides an oil-gas detection method of deep riverway sand bodies based on de-compaction, which comprises the steps of ① well logging curve editing and correction, ② acoustic wave time difference of a quasi-mudstone stratum and a sandstone stratum from shallow to deep is obtained, normal compaction trend lines of the mudstone and the sandstone are respectively established, ③ the compaction trend is subtracted from a speed curve on the well, so that a well speed curve with the de-compaction trend removed is obtained, ④ parameters such as longitudinal wave impedance, transverse wave impedance and Poisson ratio based on de-compaction are calculated, further inverse proportion Poisson ratio parameters are calculated, a threshold value of oil-gas containing exploration of a reservoir is determined through intersection analysis, ⑤ is used for carrying out pre-stack simultaneous inversion based on a Zoeppritz equation, a plurality of elastic parameter bodies are obtained, further inverse proportion Poisson ratio parameter bodies are calculated, and oil-gas containing performance of the reservoir is predicted. |
