十屋油田营城组储层裂缝类型与构造运动的关系及裂缝预澳

Relationship Between Reservoir Fractures Type and Tectonic Movement and Fracture Prediction of Yingcheng Formation, Shiwu Oilfield

以野外地质调查和岩心观察以及测井解释结果为基础，分析了十屋地区的裂缝类型和产状特征，结合十屋地区的主要构造形成期次以及相对应的应力场特征，较为全面地研究了裂缝发育与构造运动的关系，并通过古构造应力场的模拟对营城组储层裂缝进行了预测。研究认为：十屋地区的构造运动主要有5期：裂缝主要受构造运动以及构造的影响，不同期的构造运动形成不同的裂缝，根据构造应力，把该区裂缝划分为4种类型，储层在两期构造应力场作用下共形成了2期4组裂缝；裂缝主要发育方位为北东向和近南北向。

The fieht investigation and observation of cores and well log interpretation resuhs based on analysis of l0 types of housing areas and occun＇ence of fracture characteristics, combined with 10 housing areas form the main structure of time and stress field co,＇responding to the more comprehensive study of the fracture development and the relationship between tectonic movement, and through the ancient tectonic stress field in the reservoir simulation of the business c, ity crack is predicted. Research that： 10 House area of tectonic movements are mainly 5; crack hy tectonic movement, and the structure of different tectonic movement of the formation of different cracks, according to tee.tonic stress, the cracks in this area is divided into four types, reservoir In the two tectonic stress field of 4 groups formed two cracks; crack growth direction is mainly north-east and near north-south.
