Based on the observation on the core and crop fracture development characteristic and the statistics and combining with the oilfield development performance,this paper studies the earth stress field and fracture development charateristis of Fuyang reservoir in Chaoyanggou Oilfield using hydraulic fracturing data. The result shows that,Fuyang reservoir develops EW multi-directional structural fractures. The nearly EW fractures in the initial period of the oil field development has the strongest conductive capability,being the most effective fractures group.With the pressure field change in the oilfield,the effectiveness of fractures also change,appearing multi-directional water breakthrough and water swept.The limit of water injection for low permeable oilfields is to control the open degree of the fracture groups in different directions.

在岩心和露头裂缝发育特征观察和统计工作基础上, 结合油田开发动态, 应用岩心古地磁定向等室内实验方法, 利用水力压裂等现场资料对朝阳沟油田扶杨油层古今地应力场及裂缝发育特征进行了系统的研究。结果认为, 扶杨油层发育以东西向为主的多向性构造裂缝, 油田开发初期近东西向显裂缝导流能力最强, 为最有效裂缝组系。随油田压力场变化, 裂缝有效性也随之改变, 出现多方向见水及水淹现象。低渗透油田开发注水压力界限是控制不同方向裂缝组系的张开度。

; Ordovician reservoir in Lunnan Oil Field is a fractured reservoir. Its formation is controlled by fracture development. The fractures are buried deeper than 5000m, formed from multistage structural movement, and controlled by several factors in the process of evolution. The development is typical and complicated. Through observing and describing the fracture development characteristics of cores, this paper analyzes the effect of environmental change including depth, temperature and confined pressure and later movement including denudation and fracture filling on mechanic characteristics of subsurface rock body, so as to determine the controlling factors and numerical simulation parameters of Ordovician fractures. Using numerical simulation, it calculates the probabilistic distribution and development azimuth of fractures. According to calculation, it discusses the development mechanism of Ordovician fractures in Lunnan area. Combiningwith inner-well testing, it analyzes the controlling effect of fracture distribution on fluid and reservoir formation pattern.

轮南油田奥陶系油气藏为裂缝油气藏,油气藏形成受裂缝发育控制。裂缝埋深在5000m以下,由多期构造运动产生,发育机理非常典型、复杂。通过观察、描述岩心的裂缝发育特征,分析在发育过程中深度、温度、围压等环境条件的变化以及后期发生的剥蚀、裂缝充填等改造作用对地下岩体力学性质的影响,确定裂缝发育的控制因素和数值模拟参数。进而通过数值模拟,计算了裂缝发育概率分布和发育方位。根据计算结果,探讨了轮南地区奥陶系裂缝的发育机理,结合井内流体测试结果,分析了裂缝分布对流体的控制和油气藏形成模式。因此认为,综合分析裂缝形成过程及各种控制因素,定量分析其影响程度,求取经验公式,应用于应力场计算和裂缝预测模型,可以对裂缝发育区分布和裂缝发育特点做出较为准确的定量预测;综合分析各种影响因素,逐期计算各期裂缝的发育情况和应用数理统计技术求取回归关系式,是预测现今裂缝分布的关键;结合实验结果,建立确定模型参数的多元统计回归方程,是模拟最重要的基础工作。

Based on core observation and image logging data analysis,this paper described fracture development characteristics of Budatequn Buried hill in Beier Depression.Fractures are mainly extension and shear with linear density of 5-15/m,dip of 50°-60°,width of 0.1-5m,micro fractures being dominant ones,and medium fractures the second,56% fractures have been filled and 44% is half-unfilled or opened,where fracture for 3 periods are mainly developed.Integrate research on fracture development,distribution characteristic and effects etc.,have indicated that Budatequn development and distribution are controlled by long inherited fault with strong activity,lithology and single bed thickness.Using distribution density of fault,this paper predicts favorable area in Budatequn Buried hill.It also concludes that central west area is favorable for Budatequn Buried hill,among which central part and its north area of Sudernter Buried hill as well as border between south area of Huhenuoren faulted nose structural and south of Beixi depression and trough both are the most favorable area for fault development of Budaterqun Buried hill.

在岩心观察和成像测井资料分析的基础上,对贝尔凹陷布达特群潜山裂缝发育特征进行描述,得到贝尔凹陷布达特群潜山裂缝以张性和剪切缝为主,线密度主要为5~15条/m,倾角以50°~60°为主,宽度为0.1~5 m,以小缝为主,中缝次之。56%的裂缝被充填,44%的裂缝半充填和开启。主要发育3期裂缝。通过裂缝发育及分布特征与其影响因素叠合研究,得到贝尔凹陷布达特群潜山裂缝发育和分布主要受活动强度大的长期继承性断裂、岩性和单层厚度的控制。利用活动强度大的长期继承性断裂分布密度对贝尔凹陷布达特群潜山裂缝有利区进行了预测,得到凹陷中西部地区是布达特群潜山裂缝发育的有利地区,其中苏德尔特潜山构造带中部及其以北地区、呼和诺仁断鼻构造带南部和贝西洼槽南部交界处是布达特群潜山断裂发育的最有利地区。
