Abstract

Based on the previous theories for the evaluation of oil exploration efficiency, this paper analyzed the factors influencing oil exploration, and comprehensively evaluated the exploration efficiencies of four projects of SLOF from 2004 to 2009 by building a two-phase DEA model, to verify the validity of the four exploration projects under DEA.

Keywords

Abstract

Based on the theory of petroleum geology, the author systematically analyzed the oil and gas accumulation conditions of Liaodongdong exploration area of Shengli oilfield. Application of effective hydrocarbon source rock analysis, reservoir prediction and evaluation, basin analysis, basin simulation technology and method of hydrocarbon accumulation model is established. The research results show that Liaodongdong exploration area develops many sets of source rocks which buried depth below 2500 m. Hydrocarbon source rocks with high abundance of organic matter and excellent conditions for mineralization. This area develops Guanxia group and Dongying group of two sets of effective reservoir-cap combination, and develops variety of drainage system and various trap types. Different structural belt have different drainage system and trap types, formation of multiple trap types. Liaodongdong exploration area of Shengli oilfield mainly formed four types of reservoirs, which include lithologic-structural reservoir, stratigraphic overlap reservoir, stratigraphic erosion unconformity reservoirs, lithologic reservoirs.

Keywords
