| 摘 要： | 水力压裂裂缝形态是油层压裂设计首先要考虑的问题针对中原油田富县探区中生界油藏储层埋藏深度浅,跨度大(300～1100 m),储层三向地应力变化大,压裂裂缝形态复杂的情况,通过对区域构造特征、岩芯地应力、岩石抗张强度、瞬时停泵压力、压裂时缝内净压力、岩石横向非均质性等综合分析,得出该区人工裂缝以水平缝为主,垂直缝及高角度斜交缝也有可能存在,而且人工裂缝在延伸过程中还可能发生转向。 |
| 关 键 词： | 人工裂缝 地应力 瞬时停泵压力 净压力 |

| Abstract: | The characteristic of the hydraulic fractures is the first question of fracturing design. The buried depth of Mesozoic reservoir of Fuxian block is easy,strech is wide(300- 1100 metres),three-dimensional stress of the reservoir alters much and the characteristic of the hydraulic fractures is complex.Through comprehensive analysis on the regional tectonic characteristics,geostress,tensile strength of rock,instantaneous shut -in pressure,net pressure within seam and rock lateral heterogeneity,it is found that the hydraulic fractures are mostly horizon,vertica and high angle oblique fracture are also availability,and fracture in the extension process also can change direction. |
| Keywords: | hydraulic fractures crustal stress instantaneous shut-in pressure net pressure |
