Abstract:

HZ25–3 Field is the first marginal oilfield on production independently developed by platform in eastern Peal River
Mouth Basin. According to the characteristic of very thin oil column,serious heterogeneity and discontinuity of the two major
reservoirs,the trajectorys of two horizontal wells were designed accurately. The log curves from LWD tool close to the bit are
quite important to land the well succesfully,and the information of formation boundary guided the lateral placement and well
trajectory adjustment. The geosteering drilling technique was successfully applied in two horizontal wells of HZ25–3 Field,
which brought the good productivity.

Key words: marginal oilfield, geosteeling, density imaging, formation boundary detecting, 3D geologic model
