On Locating the Rectangular Seismic Working Area and Determining Well Positions
Dan Shi · Journal of Jianghan Petroleum University of Staff and Workers · 2011
When locating the seismic work area,the rectangular vertexes on the computer screen showed only the approximate coordinates from which the accurate figures had to be deduced.This paper had come up with a formula to determine the minimum envelope based on three approximate vertex figures.This formula can be used to accurately locate the rectangular working area and then easily decided whether the well coordinates are within its range.With this formula,Liaohe Oil Field drilling data base can crack the complex coding in searching program of SQL data base during the development of well positioning and mapping program
