俄罗斯卡多夫油田维宪层系储层综合评价
|
摘要
油气储层综合评价是近年来发展起来的油气储层地质学研究的主要内容。储层性质的好坏直接影响到油层的产能、注水效果及最终采收率,因此储层研究是油藏描述的核心内容之一。储层综合评价是油藏描述中很重要的内容。为了适应油气勘探开发的需要,储层综合分类评价的研究已日趋多学科性和综合性。卡多夫油田构造简单,储层特征是控制高产油层分布的主要因素,为此需要对油田储层特征进行深入研究。本论文通过对储层评价参数的统计汇总,利用模糊聚类分析方法,对储层分类评价,研究各类储层的质量分布,分析储层特征对生产动态的控制,然后对高产区进行预测。
主要取得了如下认识:
1、卡多夫油田维宪层系储层主要由砂岩和粉砂岩构成,并夹少量的杂砂岩和碳酸盐岩。砂岩储层高孔高渗,而粉砂岩中孔低渗。纵向上,下部高孔高渗,上部中高孔中高渗。
2、利用模糊聚类分析把储层分为四类,高产区都集中在I、II类储层。
3、储层的质量明显受控于沉积微相,卡多夫油田好的储层主要分布于砂坪、砂脊、潮坪中,差储层则发育于泥坪中。
4、本油田高产井基本都钻遇了高孔高渗层段,并且这些层段砂厚大,有效厚度也大,泥质含量小。
5、利用多种信息叠合法,将卡多夫油田储层孔隙度、渗透率等值线图和有效厚度图同构造图、沉积微相图等叠合,得出高产区分布特征。在C-III-1层和C-V层,高产区呈席状分布;其它各层,高产区零星分布。
本论文的研究成果,对今后整个卡多夫油田的储层综合评价起到参考作用,从而对卡多夫油田的油气勘探开发与布井起到实际的指导意义和应用价值,为改善油田的开发效果提供可靠的地质依据。
Reservoir synergistic evaluation is the main content of research on reservoir geology developing recently. And the quanlity of the reservoir has effects directly on the production of oil layers, waterflood response and the final recovery efficiency. So the synergistic evaluation of reservoir takes an important part in reservoir description. In order to meet the needs of oil/gas exploratory development, the study on synergistic evaluation of reservoir is more and more interdisciplinary and comprehensive. Kotovskoye oil field has simple structure, and the reservoir characteristic is the key factor of controlling the distribution of productive oil reservoir. So the reservoir characteristic in the oil field needs deeply studying. This paper classifies and evaluates the reservoir, studies the distribution of every sub reservoir, analyzes how the reservoir characteristic controls the production performance, and predicts the productive parts of the oil field using the method of systematical cluster analysis in fuzzy mathematics by statisticing and integrating the evaluation parameters.
The main conclusions of the paper can be declared as follows:
1. The reservoir of Weixian layer system in Kotovskoye oil field is made up of sandstone and silt sandstone, with slight greywacke and carbonate rock. The sandstone has high porosity and permeability while the silt sandstone has moderate porosity and low permeability. On vertical level, the bottom has high porosity and high permeability and the upper part has moderate-to-high porosity and moderate-to-high permeability.
2. The reservoir of this system layer is classified to four parts using the method of fuzzy cluster analysis, and the productive parts are concentrated in the classes of I and II.
3. The quality of the reservoir is controlled by the sedimentary process. So the reservoir with high quality in the oil field mainly distributes in the sand flat, sand crest and tidal flat. But the reservoir with low quality grows in the mud flat.
4. Almost all productive wells meet the interval with high porosity and high permeability, which has thick sandstone, long effective thickness, small quantity of clay.
5、The distribution characteristic of productive parts are contained by overlapping the counter maps of the porosity and the maps of the permeability and the maps of the effective thickness with the structure maps and micro-sedimentary facies maps using the method of versatile information superimpose. In other words, the productive parts are mainly located in the layers of C-III-1 and C-V, which sheet-like distribute and other layers has odd distribution which has small areas.
The achievements of this paper will be a reference for the reservoir synergistic evaluation of the whole oil-field. Then this will be guide and applicability for the exploratory development and deploying wells in the oil-field. Meanwhile, this will play an important role as replenishment for the reservoir evaluation in other oil basins of the oil region.
