摘要
松辽盆地西部斜坡区勘探潜力大,但因勘探程度低,研究难度较大。根据钻井资料,从地质上分析沉积环境,预测储层发育区,采用地层厚度梯度法分析地层尖灭的位置,综合分析地层超覆圈闭的规模及位置。研究认为,套保以西具备良好的储、盖条件和上倾方向的遮挡条件,可形成大型地层超覆圈闭,有利区面积150 km2,前景资源量5 000×104t。
Western slope of Songliao basin has large prospecting potential but with great research difficulty because of low exploration degree. This paper analyzes the sedimentary environment based on geology and drilling data,predicting oil layer development region.It determines strata pitchout location using gradient method of strata thickness,adopting integrated analysis for overlap trap size and location.Study shows the west of Taobao area has nice reservoir-seal and screening condition in the up dip direction,where an extremely large stratigraphic overlap hydrocarbon reservoir formed,with favorable area of 150 km^2 and potential resources of 5000×10~4t.
