Evaluations of oil and gas lateral migration across faults: A case study of Shigezhuang nose structure of Wen'an slope in Baxian sag,Jizhong depression, Bohai Bay Basin, China
摘要
Abstract
To quantitatively study the possibility and location of lateral migration of oil and gas across faults,a quantitative evaluation method for lateral migration of oil and gas across faults was established using the Shuangjing Knipe graphic method to identify the juxtaposition site and juxtaposition patterns of sand and sand in the upper and lower walls of the reverse faults and the consequent faults,combined with the oil and gas limit method of fault lateral seal in the test oil area.The quantitative evaluation method was applied to the first and two members of the Paleogene Shahejie strata (referred to as Es1 and Es2) of Shigezhuang nose structure of Wen'an slope in Baxian sag,Jizhong depression,Bohai Bay Basin,to determine the juxtaposition site of sand and sand in the upper and lower walls of the fault,and the shale gouge ratio (SGR) lower values are 26％ and 29％ respectively in the strata Esl and Es2.Thus,the location of lateral migration of oil and gas across faults was determined.Based on the oil and gas distribution characteristics of the strata Es 1 and Es2,and variation trend of nitrogen compounds in 4 wells in the strata Esl,the results were consistent with the quantitative evaluation of the location of lateral migration of oil and gas across faults,the feasibility of the evaluation method was preliminarily verified.关键词
