Abstract
Shengli Oilfield 3D seismic technology has gone through 40 years. In 2015, on the basis of years of technical research and test experiment, the land piezoelectric single point detector developed independently by Shengli oilfield finally finalizes and realizes industrial production. Compared to the moving coil detector, Land piezoelectric single point geophone has the characteristics of wide frequency band, large dynamic range, high sensitivity, good compatibility and strong environmental adaptability, the main technical indexes have reached the level of DSU (MEMS) digital geophone. In 2017, high-density seismic were deployed in the Luojia region and received by land piezoelectric single point detectors. This 3D seismic used small bin, wide azimuth, and high coverage observations, with a density of 3,571,000 traces/km2. Single point seismic data has the characteristics of high fidelity, rich wave field information, wide frequency range and wide azimuth. For the single point high density seismic data characteristics, According to the characteristics of single-point high-density seismic data, the vertical and horizontal resolution and fidelity of the imaging seismic section have been greatly improved by using the wide-bandwidth azimuth processing technology of relative fidelity, which has positive effect on the third 3D seismic in the eastern oil field in China.
