Study on the influencing factors of high frequency collected in summer in the Shunbei desert area
Shunbei area is located in the hinterland of the Tarim Basin desert.The surface is entirely covered by deserts,with ridges of tall dunes,dramatic elevation changes,and poor excitation and reception conditions.However,the area is rich in oil and gas resources;most are buried deep.The target layer is generally located in the Ordovician system below 7000m under-ground,which has high requirements for the quality of seismic data acquisition.Correct selection of construction time and exci-tation and reception conditions are the primary links of seismic exploration,directly affecting the quality of seismic data acquisi-tion,It is the foundation of underground geological imaging.This article introduces the changes in the quality of collected data encountered during the summer construction of collecting data in the SHUB4 area.Through experiments such as the buried temperature,humidity,depth,and shot point recollection of the detector points,it is determined that the collection of data in the desert area in summer is affected by high-temperature evaporation and wind sand movement,resulting in loose surface sand,poor coupling of the detector points,and further aggravating the high frequency collected noise.
