下寺湾油田泉63井区长2段储层特征与储层四性关系研究

下寺湾油田泉63井区三叠系长2储层为三角洲平原亚相沉积,主要储集砂体为分流河道和天然堤,油层含水较高,油水关系复杂。根据该地区长2油层区域地质背景,通过对该区数300多口井的录井、测井、试油和岩心等资料的收集、整理、校正、分析,结合岩心分析化验资料,解释制作出相关图件,对研究区低渗储层的特征及四性关系作了较为详细的剖析。通过研究,明确了该区储层的岩性、物性、含油性和电性特征及其相互关系,解决储层参数解释和油水层划分的问题,为泉63井区长2油藏进一步开发评价提供了重要的技术支撑。

The Reservoir Characteristics and Reservoir Four Property Relationship of Chang 2 in Quan 63 Well Area,Xiasiwan Oilfield

The Triassic Chang 2 reservoir of 0uan 63 main reservoir sand body is distributary channel and well area in Xiasiwan oilfield is delta plain natural levee, with the characteristics of hi water cut, complex oil-water relationship. According to the regional geological background of Chang fa gh 2r cies, the reservoir eservolr by collation, analysis, correction of the logging, wire logging, oil testing and core data collection of 300 wells, combined with core analysis data, explained and produced relevant maps of the the characteristics and four property relationship of this low permeability reservo Qu ir an 63 well area, studied Through the research the lithology, physical property, the reservoir oiliness and electrical characteristics and their mutual relations are definited, reservoir parameter interpretation and oil-water partition problem are solved, witch provides important support for further development and evaluation of Chang 2 reservoir in the Quan 63 well area .
