大庆长垣浅层气形成条件与分布规律
FORMING CONDITIONS AND DSITRIBUTION LAWS OF THE SHALLOW GAS IN DAQING PLACANTICLINE
摘要
Abstract
In recent years,the shallow gas has become the new area of Daqing Oilfield exploration.In order to improve the fast development of the shallow gas exploration,on the basis of the previous studies,with the help of the relative data 1.e.mud logging,well logging,oil test,geochemical,geophysical informations and so on,the systematical analysis was conducted for the accumulating conditions,distribution laws,main controlling element of the accumulation.The research achievements show that there are biogas and associated gas in the shallow gas of Heidimiao oil layers in the Placanticline;the sedimentary sandbodies of the delta front phase including the distributary channel,mouth bar,far sand bar,sheet sand etc.provide the acccumulating space for the enrichment of the shallow gas;the source accumulation faults penetrating Reflecting Horizon T1-T06 are the principal migrating channels for the shallow gas;the shallow gas in Placanticline Heidimiao oil layers is mainly distributed in Oil Group H2 and H3 vertically,while on the horizon,the gas is generally distributed in the top position of the structures in Punan,Aonan,Xingshugang,Saertu and Lamadian areas;the main controlling elements of the shallow gas accumulation =are the gas sources,source accumulation faults and effective structural traps.关键词
