| 摘 要： | 大井矿区一井田的测井任务是确定B1煤层厚度及分叉合并规律,正确划分煤层层位。依据该井田三个明显的标志层位,确认了该区的含煤层段,并将其西山窑中段B1煤层划分为B1、B11、B12、B11-1、B11-2、B12-1、B12-2等七个煤层编号。为提高层位对比的可靠性,将15条勘探线与十二条联络线进行测井曲线对比,确保两个方向对比结果一致。此次煤层对比可靠程度分为可靠（A）、基本可靠（B）、可靠性差（C）三级。从测井曲线对比结果看,井田的西北部和南部,煤层厚度大,分层小;井田的东北部和东部,煤层分叉多,煤层薄。

| Abstract: | The target of well logging in No.1 minefield,Dajing mining area is to determine thickness and splitting and merging regular pattern of the coal seam B1,and dividing coal seam horizon correctly.Based on three marker beds in the minefield,affirmed coal-bearing sector in the area,and divided B1 coal seam in the middle member of the Xishanyao Formation into B1,B11,B12,B11-1,B11-2,B12-1 and B12-2 seven coal seams.To improve reliability of coal seam correlation carried out logging trace correlation for 15 exploration lines and 12 supplementary lines,ensured consistency of correlated results of two directions.Three levels of reliability are divided: reliable(A),basically reliable(B) and poorly reliable(C).From logging traces correlation has found that in northwestern part and southern part of the minefield,coal seams thick and less sliced,while in northeastern part and east part,coal seams thin and splitting. |
