【摘要】：塔木察格油田N区块Z油层组段断层复杂,含油断块小且零散,无全区统一的油水界面,油水层识别难度大;油田投入开发后,未开展全区动用、未动用储量复查工作。在目前油价降低的形势下,需要加强区块经济评价研究,对未动用储量进行分类优选。本论文通过“分区块、分岩性”建立油水层解释图版,较好地识别了油层与油水同层;研究全区油水分布规律认为整体为上油下水的分布形式,各井区油水系统相对独立,没有统一的油水界面;油藏类型以岩性、构造-岩性油藏为主;采用“容积法”计算出研究区13个储量区块动用、未动用储量;采用“权重法”对研究区进行储量分类评价工作;应用“盈亏平衡分析法”对未动用储量进行经济评估;优选出未动用区块进行试验开发,取得较好效果。
[Abstract]:The formation of Z reservoir in Block N of Tamchage Oilfield has complex faults, small and scattered oil-bearing fault blocks, no unified oil-water interface in the whole area, and it is difficult to identify oil-water layers, and after the oilfield is put into development, it has not been developed in the whole area and the work of rechecking the unproduced reserves has not been carried out. Under the situation of lower oil price, it is necessary to strengthen the research of block economic evaluation and to classify and select unproduced reserves. In this paper, the interpretation plate of oil and water layers is established by "dividing blocks and lithology", and the oil and water layers are well identified, and the distribution of oil and water in the whole area is considered as the distribution form of oil and water in the whole area, and the oil-water system of each well area is relatively independent. There is no uniform oil-water interface, the reservoir type is lithology, structure-lithologic reservoir is the main type, and the "volume method" is used to calculate the unproduced reserves in 13 blocks in the study area. The paper adopts "weight method" to classify and evaluate reserves in the study area, applies "break-even analysis" to carry out economic evaluation of unproduced reserves, and optimizes unproduced blocks for experimental development, and obtains good results.
