摘 要：The Huanxiling oilfield is located in the southern part of the western slope of the western sag in Liaohe *** west side of this oilfield is connected with two sets of high-quality source rocks of Member 3 and Member 4 of Shahejie Formation in Qingshui *** oilfield has fan delta,turbidite fan and other types of reservoirs,it also has cap rock of thick mudstone in Member 3 and Member 4 of Shahejie *** background of the warped basement,the warped fault-block draped compound trap zone are developed,which includes nine types of *** perspective of hydrocarbon accumulation,the slope of this area has always been the target area for hydrocarbon migration and *** analysis shows that there are multiple stages of hydrocarbon charging in this area,and the main reservoir forming period is the sedimentary period of Member 3 of Shahejie Formation and the sedimentary period of Dongying ***-quality source-reservoir-cap conditions ensure large-scale hydrocarbon accumulation in this *** on the theory of compound hydrocarbon accumulation,many types of oil and gas reservoirs,including light oil reservoir and heavy oil reservoir,have been found in this area,with total reserves of 500 million *** view of the oilfield characterized by large reservoir burial span,multiple oil-bearing strata,strong heterogeneity and various types of oils,multi-batch seismic data processing&interpretation technology and thin reservoir inversion technology based on geological model are established in the preliminary exploration period,steam-flooding physical simulation technology of heavy oil,oil-reservoir fine description technology of thermal recovery heavy oil,steam huff and puff technology of ordinary heavy oil and steam-flooding technology of mid-deep buried heavy oil are developed in the development period,and technologies such as separate-layer injection,selective injection,sand control and lifting of heavy oil are matched and
