Abstract: The main developing problems in Wenxi No.6 block in Shanshan Oilfield have been analyzed by the studies of reservoir description, geology, digital model as well as logging, according to the research achievements of the reservoir description and geology studied with the deposition micro-faces achievements. The necessity and possibility have been proved with restudying the geology, dynamic production data, various monitoring information, and combining static and dynamic data in current well pattern. How to carry out the total project and adjust object and target have been confirmed. Three sets of the well pattern thickening adjustment schemes have been worked out and development index has been predicted. The good de-velopment effect in site has been achieved by the selected plan through the balance and optimization both in technical and economic index.
