Technical Economic Evaluation On Developing The Untabulated Reservoirs In Lamadian-Saertu-Xingshugang Oil Field

At present, many inland oil fields come into later period of producing, most major productive zone be in the state of output declining. In order to produce proven oil resources fully, some oil fields set emphasis on the development of untabulated reservoirs. Developing untabulated reservoirs have some investment risk, compared with tabulated reservoirs, so technical economic evaluation on developing untabulated reservoirs meets with much recognition increasingly.This paper aim to development of untabulated reservoirs, studied Tertiary Infill Adjusting, apply the lasted economic evaluation theory and methods to the oil development, studied the application in Lamadian-Saertu-Xingshugang Oil Field, present the evaluation conclusion of typical region. Allow for the high value of startup pressure grads of untabulated reservoirs, if the distance between wells is bigger, it's inadvisable to procedure, however if the distance small than normal will be a investment waste, so the ultimate distance is the most significant factor in Tertiary Infill Adjusting project. And then analysis the lower limit of the available reserves in different prices, in order to provide the producing decision making.Based on the economical evaluation, COM, OOP, and COM Automation theory, We developed the software of Economic Evaluation System About Tertiary Infill Adjusting, developed a COM object to provide the service of creating and viewing report table. Realized a series interface, other application can call the COM object through the interface, fulfilled reuse of the software.
