大民屯凹陷西部低潜山带储层特征
|
摘要
本研究项目利用岩心观察,薄片鉴定、扫描电镜分析、x-衍射分析、岩石化学分析、包裹体温度测定、毛管压力测定、晶格位错分析、古地磁测定等手段,结合测井资料,对辽河断陷大民屯凹陷西部低潜山带基岩储层进行了研究和探讨。
将西部低潜山带中晚元古代和太古宙基岩岩石类型划分为变质岩、沉积岩和火成岩脉三大类。认为变质岩中混合花岗岩、混合岩化变质岩、变粒岩、浅粒岩、黑云斜长片麻岩等为本区的主要变质岩类型;沉积岩以云岩、硅质岩和石英砂岩为主;火成岩脉主要为辉绿岩、煌斑岩和闪长玢岩。指出了混合花岗岩、浅粒岩、云岩、硅质岩和石英砂岩是主要的储集岩。利用岩石化学分析法并结合岩相学等特点将太古宙变质岩进行了原岩建造恢复,认为太古宙原岩为一套中、基性火山岩、火山碎屑岩和沉积岩,局部夹酸性火山岩建造。
将储层的成岩演化划分为四个阶段:即早期区域变质作用和混合岩化作用、中晚元古代和古生代沉积成岩作用、中生代地壳抬升阶段潜山地层的改造作用和新生代断裂对潜山的改造作用。利用包裹体温度测定对裂缝充填物的来源和充填时期进行了探讨。储集空间类型包括两大类九种类型,从储层演化角度对基岩储集空间发育的受控因素进行了分析,指出构造作用、充填作用、风化剥蚀、溶蚀淋滤、岩石矿物类型是影响本区储层发育的主要因素。
对西部低潜山带8口重点井进行了单井储层特征的详细描述和综合评价。通过区域应力场分析,对研究区进行了古构造应力场模拟和裂缝发育程度预测,结果认为最大主应力值在110～80Mpa,为压应力,太古宇基底高值区主要分布在胜23井以北和沈166井以南;中元古代盖层高值区在沈229井附近及沈169井以南,应力值在-90Mpa以上,裂缝发育区与最大主应力分布一致。
This research item makes use of core observation,the thin slice authentication,scanning electricity mirror analysis,X-diffraction analysis,petrochemical analysis,pakage body temperature degree measurement,hair tube logging data in order to make a study and discussion on bedrock reservoir bed of Liao River low DaMin village sunken western low burial hill zone.
We divide bedrock rock types in the middle and late Proterozonic Era as well as the Archaean Era into three types ,which are metamorphic rock ,deposition rock and the igneous dike.We think main metamorphic rock types of this area include mited granite ,mixed metamorphic rock,leptite,etc.The main types of deposition rock are silicatite and quartz sandstone.Making use of petrochemical analysis and petrography,Werecover ancient rock’s construction on the Archaean Era,Through the practice,We find bedrock consists of a set of neutrality and basis volcanic rock ,volcanoclastic rock ,deposition rock and partial volcanic rock with acidity.
We divide the evolution of becoming rocks into four periods: early region’s metamorphic process and mixed lithifaction,sedimentation and becoming rocks process in middle and late Proterozonic Era and in the Paleozonic Era,trasformation process of burial hill layers in earth shell’uplift period in the Mesozonic Era, and transformation process to burial hill in the Cenozonic Era.Through package body temperature degree measurement, we make a study on the source and packing period of fissure packings. Reservoir space types include two categories and nine types. From the point of reservoir bed’evolution, We analyze factors of bedrock reservoir space’s development. The thesis points out the main factors which affect the reservoir bed development of this area. These main factors include tectonic action, packing action, weathering, corrosion, as well as rock and minerals types.
We have analysed eight important oil wells of this area, and have made detailed description and comprehensive evaluation on single well’s reservoir bed characteristics. According to the analyses on region stress field, We simulate ancient tectonic stress field and predict fissure development degree on research district. We get the results that maximum main stress value is 110~80 Mpa, mainly distributes in the North of oil well of sheng23 and in the South of oil well 166 of shen. The high value zone in middle Proterozonic Era is near well 229 and in the South of well 169 of shen, and stress value is above-90Mpa. The fissure development region accords to maximum main press.
