| 摘要: |
| 雅克拉构造位于中国新疆塔里木盆地东北部,沙雅隆起的中段,为一高断块,地处南北侧两个生油拗陷油气运移指向的聚集地带。布于构造上的沙参2井于奥陶系获高产工业油气流。在油气化探工作中,土壤气体测量法属多指标找矿法。,在数学地质领域内,因子分析(R型或Q型)是一种多元统计方法,是用以进行系统分类和成因分类的重要手段。 |

| Abstract: |
| Geochemical survey was made in Yakela structure area in 1987. 195 soil samples were taken for measurement and 13 gaseous geochemical indicators were made for R-type, factor analysis. According to the characteristics of factor loading, the author divided the 13 indicators into 4 types and Predicated 4 oil and gas potential zones with 12. high geochemical anomalies. Three producing wells (Shaean-2, Sha-4 and Sha-7) are located within the two geochemical anoma-lies. 10 prospective oil land have been predicated by this method. 8 anomalous zones from these favorable areas have higher factor score than that from well Shacan-2 area. Note that there is a single and circular geochemical anomaly with the coverage about 6km2 at the well Shacan-2 area. This is not shown from other geochemical map in the same area, In order to comparing the distribution eharacter of the surface geochemical anomalies determined, the author repro-cessed the diagram data in 1993 by computer mapping procedure and solved rationally the prob-lem of the origin for several higher factor scores resulting in the correction of originakl geo-chemical anomalous zones in the studied area, |
