州201区块扶杨低渗透储层地应力场模拟
|
摘要
地应力场模拟技术主要是测井、地震、地质、油藏工程、计算机等多学科高度紧密结合的一项研究,介于地质与工程之间的交叉学科。目前,国内外地应力场模拟技术研究主要集中在井筒附近,而对于井间应力场模型研究的较少。
本文分析和研究了大庆油田扶杨低渗透储层岩石力学特征,利用三维地震资料和测井资料结合建立了州201区块扶杨低渗透储层的地应力场,利用多元回归计算方法,建立了泊松比、杨氏模量、岩石破裂压力、岩石闭合压力等岩石力学参数常规测井曲线计算模型,清楚地反映出井间纵向上和横向上岩石力学性质的变化,尤其是应力大小和应力夹层的变化,为压裂参数设计提供了依据。
同时,研究利用物质守恒原理,通过三维平衡剖面,进行构造演化模拟,得到了相对应变量、绝对应变量、构造曲率数据体,为压裂人工裂缝预测的提供了重要基础。
通过可视化技术实现了沿任意井轨迹地应力场三维数据体灵活展示,能够输出并加载到GOFER等压裂设计软件上,实现压裂优化设计。
The simulation technique of the In-situ stress field, which is the combination of logging, seismological, geology, reservoir engineering and calculator technique, is an interdisciplinary between geology and engineering knowledge. Now,the Simulation technique of the In-situ Stress Field is more of focusing on the region of well neighbor at home and abroad, and there are few studies on stress field model among wells.
The rock mechanics characteristic of low permeability reservoirs of Fuyang formation in Daqing field is analyzed and investigated in this paper. The In-situ stress field of low permeability reservoirs of Fuyang formation in Zhou201 Block is established by combining of 3D seismic and logging data. A conventional log curve computation module, which is established by using multiple regression calculation procedure, can calculate Poisson ratio, Young's modulus, fracture pressure and shut-in pressure of rock, and other rock mechanics parameter. The change of rock mechanics property in both longitudinal and transverse direction among wells is reflected by this module clearly. Especially, the change of both stress intensity and stress barrier can provide evidences of fracturing parameter design.
Meanwhile, base on conservation of matter theory, the relative strain capacity, absoluteness strain capacity and structure curvature data, which provides the importance foundation for prediction of man-made fracture, is gotten by structural evolution simulation of 3D equilibrium profile.
The three-dimensional data of in-situ stress field along whatever tracks of well-bore,which is realized by using visualization technology, is outputted and loaded in GOFER to implement fracturing optimization design.
