The research in this paper provides new methods for the detection of fractured reservoir detection, oil field exploration and exploitation and abundant experience of research on fractured reservoir.
3 Through analysis to tectonic stress field, pre-stack and post stack seismic attributes, thecomprehensive prediction method to fractured reservoir is studied.
The geometry and density of fractures are the main parameters used to describe fractured reservoirs, and they are also the main factors controlling the oil & gas production of fractured reservoirs.
Considering characteristics of fractured reservoirs in buried hill in Budate Group of Beier Sag in Hailaer Basin, and starting from structural characteristics, this paper characterizes fracture distribution rules quantitatively using top surface structure curvature method based on qualitative analysis on relation between reservoir fractures development degree and overlapping formation thickness and contact relation between reservoir and overlapping formation.
Taking the whole feature of fracture zone as studied target,the results of numeric simulation obtained by the method are more consistent with reality,which provides a new idea and method for study of wavefield feature in fractured reservoirs.
5, Evaluation of the fracture reservoir with gray system network: Identifying the fracture with gray system theory is explored in this study, the gray theory analysis model of fracture , fracture occurrence and fracture extent identify and growing evaluation is built using the gray connect identified method and combining with the conventional log data in T3x2 of Xiaoquan-Xinchang area in west Sichuan.
The farther study list as follows:1,All kinds conventional log data are synthetically used to study the fracture reservoir: The response characteristic of all kinds conventional log data of Tax2 in this area is summarized to make the manual interpretation.
In this paper, with the help of advanced geology, geological statistics, random and fractal geometry, fractal simulation has been applied to establish a precise geological model of fractured sandstone reservoir.
5 The research indicates that the development of basement crust from disintergration inSudert area of Hailaer basin is controlled by formation lithology and tectonics.
Experimental and industrial observations indicate a strong nonlinear dependence of the parameters of the flow processes in a fractured reservoir on its state of stress.
High oil production from the Proterozoic formation of Shen 229 block in Damingtun Depression, Liaohe Basin, China, indicates the presence of natural fractured reservoir whose production potential is dominated by the structural fracture.
This paper examines the two-phase flow for a horizontal well penetrating a naturally fractured reservoir with edge water injection by means of a fixed streamline model.
They not only reveal the essential characteristics of fractured reservoirs but also generalize and develop the existing primal results of homogeneous and porous media.
