PRODUCTIVITY STUDY OF HORIZONTAL WELLS PATTERN

With the development of horizontal well technology, the fashion of exploiting pattern has been gradually changed to horizontal well pattern from single horizontal well, so it’s very important to forecast the product condition of the horizontal well pattern exactly. In this paper, the analytical productivity of single horizontal well network in the boundless oil field is discussed, and with theory analyzing, the method is found to forecast productivity of the horizontal well network union. By comparing with the experimental productivity, the method has been also modified and the precision of the new semi-analytical and semi-experimental method is much better than before.
