摘要
油藏描述是20世纪70年代末由斯伦贝谢公司首先提出的以测井为主体的油藏描述技术,它以测井资料为中心,较广泛地反映油藏的特征。研究工区地处辽宁省锦州市锦县境内西南地区；区域构造位置属辽河断陷西部凹陷西部斜坡南段；工区范围北起锦2-19-7井,南至锦93井,西至锦94井,东至锦45-11-20井,面积约25km2。
采用的研究方法主要有：三维地震结合动静态资料的精细构造解释技术；全区小层划分对比统层；细分沉积微相和微构造研究技术；以测井资料为基础的多井储层评价技术；储层三维模型建立技术；测井二次评价技术；剩余油潜力综合评价技术；地质、油藏、数模一体化研究剩余油分布技术。技术关键包括微构造研究技术；精细储层描述与建模技术；储层非均质性研究；水淹层的识别技术与水淹程度的量化；剩余油分布研究技术；滚动探井井位的确定。
本文取得了如下成果：发现并落实了新的圈闭5个,圈闭面积1.5km2,其中有利于油气成藏的圈闭3个,面积0.8km2,部署滚动井井位3口。基本搞清了工区内主要的断裂系统及平面展布关系。通过对主要含油气目的层的三维地震资料精细解释,基本落实了区内断裂系统的平面展布及空间的叠置关系。搞清了本区沙三段油气藏分布特点和成藏控制因素。通过沉积相研究,确定了本区早第三纪特殊沉积环境下发育的二种沉积相类型及平面展布特点。对于沙三段大凌河油层的储层进行了精细的描述和评价。
The description of reservoir is firstly proposed by Schlumberger in the late 1970s, which is based on logging. It takes doghouse dope as the center and reflects the character of the reservoir. The work area which used to be researched is located in southwest of Jin county of Jinzhou municipality in Liaoning province. The area structure's position belongs to the west of the fault depression, the west of the sunken and the south of the slope in Liaohe. The work area is from the well of Jin 2-19-7 in the north to the well of Jin 93 in the south, from Jin 94 in the west to Jin 45-11-20 in the east, it covers about 25000 square meters.
The main methods to be adopted as follow:The 3D seismic combining dynamic and static data of fine structure interpret technique, the researching technique of subdivided depositing microfacies and microtectonics, the evaluating technique of multi-well reservoir stratum, which is based on doghouse dopes, the technique of establishing 3D modeling of the reservoir, the technique of second evaluation to the logging, the comprehensive evaluation technique of lateen capacity of oil remaining, the researching technique of geology, reservoir, digital integration to the oil remaining, the technique of description and model building to the fine reservoir, the research of reservoir heterogeneity, the technique of identifying swept layer and quantifying the degree of flooding, the researching technique of the distribution of oil remaining, the certain of the well location of rolling prospecting wells.
The outcomes acquired by this passage as follows:discovering and ascertaining 5 new traps, the area of the traps are 1500 square meters. In these traps, there are 3 of them are in favor of becoming reservoir stratum the area is 800 square meters. And 3 rolling wells are also deployed. We also basically know the relationship between rift system and plane distribution in the work area. The relationship between system and plan distribution is mainly ascertained by expounding the fine 3D seismic data of the main oiliness bed of interest. The passage also tells the character and control factor of the reservoir. By researching the precipitation facie, confirming the type and the character of the plan distribution of two kinds of precipitation facie which develop in the special situation of paleogene. The reservoir of Shasan of Daling River is alertly depicted and evaluated.
