岩心定向与储层裂缝探测技术研究进展

Research progress in core orientation and reservoir fracture detection technology

储层裂缝对油气勘探和开发具有重要意义,虽然研究裂缝的手段和方法有很多,但是还缺乏有效且成本较低的技术手段。裂缝研究首先要解决的是岩心定向的问题,文中归纳总结了目前各种岩心定向的方法和技术,综合评价各种技术方法,认为古地磁岩心定向技术是最直接、有效且应用广泛的定向技术。在此基础上,总结了目前裂缝探测的各种方法和技术,并对其分别进行了评述,提出综合各个学科和技术,发挥各技术和资料的优点,对储层裂缝进行综合研究,开展点、面、体3个层次全方位的裂缝研究,从而指导油气田的勘探和开发。

Reservoir fracture is very important for oil and gas exploration and development.Although there are many methods of detecting fractures,no one can clearly identify the fracture with high efficiency and low cost.As we all know,if we want to know the information of fracture in core,the first problem is core orientation.This paper sums up and evaluates some kinds of means and techniques for core orientation.It is considered that the paleomagnetic core orientation is the direct,effective and widely used technique.Based on this,it also summarizes and evaluates some kinds of fracture detection methods and techniques.It suggests to make full use of the advantages of various disciplines and techniques and comprehensively study the reservoir fractures from the three levels of point,layer and space in order to guide the exploration and development of oil and gas field.
