Abstract

Abstract:

The first member of Xishanyao formation(J₂x₁) in Wellblock LU9 is a reservoir with bottom water, which is mainly controlled by structure and affected by lithology in local areas. The results of formation test, production test and development test have proved that the reservoir has liquid producing capability, the lateral water cut is very different and the vertical OWC is complicated. In order to determine favorable development areas, it is urgent to conduct a research on fine 3D geological modeling. Based on the data of core, well logging, formation and production test and using Petrel modeling software, a 3D fine geological model was established to determine the oil layers and the spatial distribution of reservoir parameters in the study area. And according to the prediction of the model, favorable reservoirs with good lithology and physical properties were selected to allocate development wells. The fine geological model has been confirmed consistent with the real data, which provides a reliable basis for reservoir development and well allocation.

Key words: Luliang oilfield, Xishanyao formation, bottom-water reservoir, geological model, favorable reservoir, well allocation
