- W2357019914 abstract "The H3+4+5 6reservoir of Pinghu oil and gas field is a structural one with bettom water, which has good oil property and reservoir quality, however whose oil pay is not very thick. The optimization of perforation plan is the key process for decreasing bottom water coning and increasing recovery efficiency. The paper began with working on the reservoir character, and then, from various aspects, optimized the perforting completion plan for H3+4+5 6. The raservoir charcterization study showed that H3+4+5 6 is a structural reservoir with bottom water under normal pressure and temperature condition, which is of good fluid property and reservoir quality, and the reservoir rocks are well consolidated. The sensitivity study result showed that perforation should be made at the top of the reservoir, the perforating percentage should be controlled at about 30%, tubing conveyed underbalanced perforating technology and high quality perforation devices should be used. The proper azimuth of perforating gun should be 120°, and mediate shot density should be selected. On the base of detailed study the decision was made that shot be made at the top of H3+4+5 6 at Wells A1, A2 and A4 and perforation plan was made. Afer the implementation of the perforation plan two wells' (A1, A2) production performance went well. Though the wells were put into production in high speed, therate and tubing pressure was kept stable, the water cut and GOR increased slowly, and no sanding was found." @default.
