NEB Basement-2井潜山地层压力低（钻井液设计施工密度0.9

The buried hill formation pressure of Well NEB Basement-2 is low (design and construction density of the drilling fluid is 0.94-0.98g/cm³), and the temperature is high (185℃). The GW-AMO gas-to-liquid synthetic base drilling fluid technology is used to drill under low-density conditions. The liquid has good high temperature resistance and anti-collapse and plugging performance, which meets the requirements for safe drilling of underbalanced directional wells. At the same time, the compatibility of the system is good, and the remaining old pulp stored by Party A for nearly a year from other operating parties is reused, which provides strong support for Party A to reduce costs and increase efficiency.

NEB Basement-2 well submersible mountain layer pressure is low (drilling fluid design and construction density 0.94-0.98g/cm3), high temperature (185 degrees C), the application of GW-AMO gas oil synthesis base drilling fluid technology, drilling fluid under low density conditions against high temperature and anti-collapse sealing performance is good, to meet the needs of non-balanced well safety drilling. At the same time, the system compatibility is good, the reuse of Party A storage for nearly a year of other operators of the remaining old pulp, for Party A to reduce the efficiency provides a strong support.

The buried hill formation pressure of NEB basement-2 well is low (the design and operation density of drilling fluid is 0.94-0.98g/cm3) and the temperature is high (185 ℃). The application of gw-amo gas to oil synthetic base drilling fluid technology has good high temperature resistance and anti collapse plugging performance under low density conditions, which meets the safety drilling requirements of underbalanced directional wells. At the same time, the system has good compatibility and reuses the residual old pulp stored by Party A for nearly a year, which provides strong support for Party A to reduce cost and increase efficiency.
