【摘要】：油田目前已进入高含水后期开发阶段,每年新增产能及可采储量逐渐减少,寻找新增可采储量缓解储采失衡矛盾是一项很紧迫的任务,而窿15区块储层是油田高含水开发后期接替潜力资源。因此需要准确的计窿15区块储量,为合理开发窿15区块油层提供重要依据。本文研究了窿15区块油层的构造特征、储层特征、油藏特征。根据沉积特征和电测曲线把窿15区块油层划分为三个计算单元。通过岩心、测井曲线及各种分析化验资料对油层的沉积相进行了详细描述。对窿15区块油层的油藏类型、压力与温度、流体性质、油层产能情况进行了研究。本文对地质储量的计算参数进行了确定。依据油藏剖面图和有效厚度发育情况圈定了含气、含油面积。通过对储层四性关系、有效厚度物性标准、有效厚度电性标准的研究,确定了有效厚度解释标准。利用密闭取心资料、高压物性资料、原油分析资料确定了有效孔隙度、原始含油(气)饱和度、体积系数、原始气油比、原油密度等参数。采用容积法计算了窿15区块天然气地质储量和石油地质储量。
[Abstract]:At present, the oilfield has entered the stage of high water cut, and the new production capacity and recoverable reserves are gradually decreasing every year. It is an urgent task to find new recoverable reserves to alleviate the imbalance between storage and production.The reservoir in Block No. 15 is a potential resource in the later stage of high water cut development.Therefore, it is necessary to provide an important basis for the rational development of reservoir in Block No. 15.In this paper, the structural characteristics, reservoir characteristics and reservoir characteristics of reservoir in Block No. 15 are studied.According to the sedimentary characteristics and the electric survey curve, the reservoir of Block 15 is divided into three calculation units.The sedimentary facies of the reservoir are described in detail by means of core, log curves and various analytical and laboratory data.The reservoir type, pressure and temperature, fluid properties and productivity of reservoir are studied.The calculation parameters of geological reserves are determined in this paper.The gas-bearing and oil-bearing areas are delineated according to the reservoir profile and the development of effective thickness.The effective thickness interpretation criteria are determined through the study of the four properties of reservoir, the physical property standard of effective thickness and the standard of electrical property of effective thickness.Using closed coring data, high pressure physical property data and crude oil analysis data, the effective porosity, original oil (gas) saturation, volume coefficient, original gas-oil ratio, crude oil density and other parameters are determined.The geological reserves of natural gas and petroleum geology in Block No. 15 are calculated by volume method.
