Abstract

In the early stage of M Development Zone, the dense well pattern data were used to carry out three-dimensional structural modeling. Because the breakpoints encountered by some wells could not be combined, the spatial distribution of faults was not accurate enough, and the well location deployment should hide faults, which affected the remaining oil potential exploitation near the faults. Since 2008, the study of well-seismic combined with fine structure description has been carried out, and the accurate characterization of faults with a fault spacing of more than 3m has been realized. The research results will be used to guide the remaining oil tapping potential in time, and the risk area has changed into potential area near the fault. Through the study of technical boundaries such as fault optimization, well location optimization, well trajectory optimization and well completion optimization, the potential tapping technology of directional wells with large inclination at fault edge is established, and the idea of tapping potential by “sticking faults and cutting corners” is put forward, that is, drilling directional wells on parallel fault surface to tap remaining oil. The average daily oil production of single well with high inclination has been implemented, and the comprehensive water cut is 75.4%. The remaining oil at fault edge has been realized. Effectively tap of residual oil.
