| 目前中国致密砂岩油气开采通常选用水平井压裂的开发生产方式,这对地下储层砂体特征认识提出了更高的要求。针对直井距离远,地震资料品质差的地区,合理应用已有的水平井信息进行平面单砂体识别及边界厘定,可以有效提高储层内部单砂体分布特征描述的精度。该研究以松辽盆地南部长岭凹陷乾安地区X水平井开发区扶余油层为例,建立直井及水平井联动的单砂体识别方法,对该地区储层单砂体分布特征进行精细研究。研究结果表明:乾安地区扶余油层存在两种单砂体分布模式,其一是早期三角洲平原沉积的“河控带状体”,其二为晚期三角洲前缘的“河控面状体”。该研究成果对同类型油田储层砂体分布预测和油田开发方案编制均具有指导意义。 |
| 英文摘要: |
| At present, the development and production mode of horizontal well fracturing is usually used in tight sandstone oil and gas production in China, which puts forward higher requirements for the understanding of the characteristics of the sand body of the underground reservoir. In the area where the vertical well is far away and the seismic data quality is poor, the reasonable application of the existing horizontal well information for plane sand body identification and boundary determination can effectively improve the accuracy of the description of single sand body distribution characteristics in the reservoir. Taking Fuyu reservoir of X horizontal well development zone in Qian’an area as an example, the method of identifying single sand body of vertical well and horizontal well linkage is established, and the distribution characteristics of single sand body of reservoir in this area are studied carefully. The results show that there are two kinds of single sand body distribution patterns in Fuyu oil layer of Qian’an area, one is the “river controlled zonal body” of the early delta plain deposition, the other is the river controlled plane body of the late delta front. The research results have guiding significance for the sand body distribution prediction of the same type of oil field and the formulation of oil field development plan. |
