Development of sandy field and application of research in Ningxia

Study on evolution characteristics of sandy-field in arid region

Study on sandy-field ecosystem effection was carried in Zhongwei Xiangshan aera of Ningxia in 2007.

A technology to tap potential and stabilize production for offshore sandstone oilfields of lowamplitude anticline;

The characteristics of sweep efficiency and oil-displacement efficiency during the polymer flooding in the heterogeneous sandstone oilfield were studied by oil-displacement experiments on three-dimensional physical models.

Field logging tests were made in Daqing Oilfield in order to verify their applicability in the sandstone oilfield, especially in the well the formation series is consist of thin and across shaly-sandstone.

Diagenetic reservoir facies and pore space evolution of low permeability reservoir in Shaxi oilfield;

Taking first member of lower Ganchaigou formation of Paleogene(E13) at Shaxi Oilfield as an example,the diagenesis,diagenetic sequences and stages were studied based on the analytic data of casting thin section,image analysis,scanning electron microscope,electron probe energy spectrometry,cathodoluminescence microscope,X-ray diffraction of clay minerals,vitrinite reflectivity of well core samples.
