秘鲁塔拉拉油区是一个已有120多年勘探开发历史的老油区。已有探井3321口,开发密度已达到每平方公里24口井。目前油田开发已到了产量递减的后期。本区过去除了作过1∶10万重力普查,部分地区作过1∶5万重力详查,地震属空白区。曾通过补钻来稳定产量,但未获成功。为此,决定进行三维地震。1995年石油地球物理勘探公司承接该项目的三维采集、处理和解释的全部工程。通过三维地震搞清了油田的整体地质状况,含油气储集层分布规律,井与井之间地层和储集层的横向变化等,找到了有利断块和其它类型构造,调整了油田开发部署,提高了钻探成功率。
Peru Talala oil region is an old oil region that has more than 120 years of exploration and development history. There have been 3321 exploration wells, development density has reached 24 wells per square kilometer. At present, oilfield development has reached the late stage of declining production. Except for the 1: 100,000 gravimetric census conducted in this area in the past, 1: 50000 gravity surveys were conducted in some areas and the earthquake was a blank area. We have stabilized the production through make-up but have not been successful. To this end, the decision to carry out 3D seismic. 1995 Geophysical Prospecting Company to undertake the project’s three-dimensional collection, processing and interpretation of all the works. Through the 3D seismic survey, the overall geological conditions of the oilfield, the distribution pattern of oil and gas reservoirs, the horizontal variation of strata and reservoirs between wells and wells, etc. have been found, favorable fault blocks and other types of structures have been found, and the oilfield development and deployment has been adjusted , Increased drilling success rate.
