Research On The Deployment Of Interspaced Horizontal Wells Of The Chao503Block

Based on detailed geological information and Seismic horizon interpretation datacollection, taking full use of three-dimensional accurate structure interpretation technology tofinish accurate structure interpretation work, applying of petrel geological modeling software,combining phased technology and the seismic sand body model for accurate and detailedreservoir prediction, we can detailed describe the sand body space distribution pattern. Underthe guidance of sand body model, combining with attribute model, we can carry on horizontalwell trajectory design. In the coarsening process we ensure certain accuracy.Using reservoir numerical simulation software, combining the reality of oilfield dynamicdata, we carry on history matching. Based on the matching result which satisfy a certainaccuracy, we design and predict a variety of solutions for horizontal well position, length, theproposed multiple fracturing design and so on. Then ultimately the most appropriateoptimization design is given. In this paper, a total of five horizontal wells are designed, whichcan offer a powerful technical basis for guiding the design of oilfield development encryptionwell and fracturing design at the later stage of development.
