M油田浅层油藏描述
|
摘要
M油田浅层为边底水驱构造油藏,油藏规模小,没有统一的油水界面,大部分油藏沿断鼻高位富集,油砂体往往有互相尖灭的现象。2007年以来大规模推广应用水平井技术,含水上升快,同时又缺乏后续接替层,稳产难度大。为此2009年浅层重新开展新一轮精细油藏描述,指导油田下步开发工作,夯实稳产基础。
本论文集成运用高精度等时地层对比、沉积相研究等技术,进行小层精细对比,划分单砂体,开展主力断块的小层微构造及储层研究。开展研究区小层精细对比与闭合工作,对小层分层界线进行了调整,对部分断块局部构造、含油面积、油水边界进行调整；从单井相入手,选择典型小层对区内沉积微相进行了进一步研究,对地区沉积特征进行再认识；对构造对油气聚集的控制作用、断裂活动对油气的运聚成藏作用进行分析。分析认为受西南庄断裂的活动的控制,M油田浅层为滚动背斜构造的主体,研究区内断层遮挡鼻状构造油藏油气较富集；储集层岩性、物性的不稳定性形成对油气遮挡,多数单个油藏体油水边界线为岩性(或物性)界面。在此基础上,重新复算了研究区的地质储量并进行了评价,形成了一套适合复杂断块油藏精细描述的技术思路和方法,为油田后续开发调整奠定了基础,提供了依据。
Shallow layer inM Oilfield is a structural reservoir that drived by edge and bottom water, the scale reservoir is small and there is no uniform oil-water interface.Most of the reservoirs are high enriched along the broken nose,oil sand is often pinch each other.Since 2007, the horizontal well technology has been large-scale applied, but the containing water rose muickly, lack of layer that follow-up to take over at the same time, the difficulty of steady produce is great. To do this from 2009, a new round of reservoir description has been developed in shallow layer,it can guide the further development and it can reinforce steady foundation in oilfield.
In this thesis,it integrate to exert the technimue of high-precision emual-time stratigraphic correlation technimues and sedimentary facies investigation and so on. It contrast layer accurately and plot out single sand body and carry out research on microstructure and reservoir of a small layer in the main block, work on small layer compared with the closed accurately, adjust small stratified boundary layer and local structures,oil-bearing area, oil-water boundary on the part of the block. Thesis start from the core facies, further study microfacies of a small layer selected of typical of the region and understand sedimentary characteristics of shallow layer in M Oilfield, analysis the role of structural control action in the process of hydrocarbon accumulation and the role of fault activity in the process the oil and gas migration and accumulation. After analysis, we believe that controlled by fault activity of Southwest village, shallow layer in M Oilfield is the main subject of anticline rolling, the oil reservoirs of nose structures blocked by faults are more enriched,the instability of reservoir lithology, physical properties is the block in the formation of hydrocarbon ccumulation, most of the boundary line of a single reservoir is the rock body of water (or physical) interface.In the basis, we recalculate geological reserve in the study area and evaluate the geological reserve. After the study, a set of technical ideas and methods suitable for complex fault block reservoir description is formed. These studies have laid the foundation and provide the basis for the subsemuent development of oil fields
