Abstract

At present, the management of natural gas exploration and development, production and sales in China’s oilfields are being strengthened simultaneously, and the purpose is to better realize the commodity rate of natural gas. The natural gas potential evaluation and target sifting will be entrusted to professional institutions. This paper focuses on the natural gas potential evaluation and target sifting of ban 18 well area in Dagang Oilfield involved in the comprehensive research project undertaken by Dagang Oilfield Geophysical Research Institute. Through the combination of 248 km2 seismic data processed by splicing and 380km2 seismic data of Banqiao, this paper studies fine structure interpretation, reservoir prediction and distribution of oil and gas reservoirs in oil-gas rich area in Banqiao, sifts the target areas of pre-exploration and evaluation, and puts forward recommended well locations to realize the increase of natural gas reserves.
