摘要
油砂矿埋藏浅、黏度极高,其勘探评价方法与常规油气有较大区别。准噶尔盆地风城地区油砂矿采用小孔距钻孔、全孔段取心识别油砂,依据原油质量分数确定油砂层有效厚度及储量,对油砂矿进行勘探评价。选择同一断块,采用钻孔和钻井2种方法勘探,通过对比发现,2种勘探方法确定的油砂层有效厚度基本一致,储量计算结果接近。
As oil sands are characterized by shallow burial and high viscosity, its exploration and evaluation methods are different from those of conventional oil and gas. Technologies of small spacing hole drilling and full hole-section coring are used to recognize oil sands, and the effective thickness and reserves are determined on the basis of crude oil mass percentage of oil sands, based on which the exploration and evaluation are carried out for oil sand ores in Fengcheng area of Junggar basin. Selecting a fault block and using 2 exploration methods of hole drilling and well drilling, the comparison analysis shows that the effective thicknesses determined by the 2 methods are congruent and the reserves calculation results are close to each other.
