从四川石油管理局地质调查处于1996年1月下旬召开的勘探成果汇报会上获悉,1995年,四川探区共对13口井的地震成果资料进行了钻探符合率检验,符合率为76.92%。至此,“八五”期间四川探区共对262口井进行了钻探符合率检验,平均符合率为83.97%,超过了考核指标(75%)。以山地地震勘探为主的四川探区钻探符合率一直保持在较高的水平,借助的是现代数字地震技术。勘探人员克服了四川地区地形恶劣、地质情况复杂等多种困难,充分发挥数字地震仪等先进装备的技术优势,以提高质量、确保勘探精度为中心,坚持取全取准第一手资料,对所获资料进行精细处理解释,形成了独具特色的山地地震勘探技术系列。钻探单位依据提供的
It was learned from the report of exploration results held by the Geological Survey Office of Sichuan Petroleum Administration in late January 1996 that in 1995, a total of 76.92% of the drilling wells were matched with the seismic data of 13 wells in the Sichuan Exploration Area. At this point, during the “85” period, a total of 262 wells were drilled in the Sichuan Exploration Area for drilling coincidence rate test, with an average coincidence rate of 83.97%, exceeding the assessment target (75%). The coincidence rate of drilling in Sichuan exploration area mainly based on mountainous seismic exploration has been kept at a high level with the help of modern digital seismic technology. The exploration personnel overcame many difficulties in the terrain and complex geological conditions in Sichuan and gave full play to the technical superiority of advanced equipment such as digital seismographs. With the focus on improving the quality and ensuring exploration accuracy, The data obtained for fine processing and interpretation, forming a unique series of mountain seismic exploration technology. Drilling unit based on provided
