[Abstract]:Sidetracking horizontal well technology, as an important technical means to greatly improve oil and gas recovery, reduce the comprehensive cost of oil and gas production, improve the degree of reserve production and increase production by tapping potential, is used to prolong the service life of oil and gas wells. Reducing production cost, improving well pattern and improving the development effect of old oil area have played an important role, and more attention has been paid to it in the later development process of oil fields at home and abroad. After more than 30 years of development, the oil field production is facing the severe situation of high water cut (average 66%) and low single well production (average 6 t). Therefore, the sidetracking horizontal well technology is introduced and popularized in Gedeba Oilfield. Taking advantage of sidetracking horizontal wells to restrain water cut, reduce production pressure difference, improve oil well productivity, fully tap the potential of closed wells, casing damaged wells, low production wells, high water cut wells, improve the utilization rate of old wells, reserve production degree and production speed, Improve the effect of oil field development. After analyzing and studying the geological characteristics, injection-production performance and production status of the reservoir in Gedeba Oilfield, this paper implements the main production layer of the oil field, combined with the analysis of the development performance of each layer of the oil field and the remaining recoverable situation of each layer. The target horizon of sidetracking is screened out, and the remaining oil is analyzed, so as to select the sidetracking target well. According to the specific situation of the target well, the altitude depth and horizontal section length of A, B target are designed. The implementation of contralateral drilling shows that sidetracking horizontal well technology is of practical significance to improve the production capacity of Gedebye and reduce the development cost of old oilfields. This technology can become one of the most effective measures to increase production. It is further popularized in other oil fields of MMG.
