Study on Adjustment Well Planning Method of Offshore Oilfields

摘要

In oil fields of western South China Sea, adjustment well planning is normally based on geology and reservoir analysis of each oil field, then combined with production performance and potential tapping plan, propose recent planning specifically. It has difficulty in medium and long-term planning, so that adjustment well number and production planning is difficult and inefficient. Aiming at difficult prediction in medium and long-term planning of adjustment well, this paper proposed a new prediction method of adjustment well planning which applies to oil fields of western South China Sea. According to study on oil increasing law of 74 successful adjustment wells in 17 oil fields of western South China Sea, finally gets water rising law and oil decline law of different types of adjustment wells. It can guide adjustment well number planning and production planning.
