大５２块是一个油层深且薄、低渗透、天然能量不足的油田，原油具有凝固点高和含蜡量高的特点。自１９９３年以来，为改善油藏的整体开发效果，先后采取了水力泵深抽工艺，柱塞泵高压注水工艺，油藏整体压裂改造工艺和油藏监测技术。通过四项配套技术的应用，提高了油井的产能，使该块的开井时率达９６％，累计生产原油３０３５７１ｔ；使该油田的平均日产油水平由６５ｔ／ｄ上升到２１２ｔ／ｄ，为同类油藏的开发提供了参考模式
Large 52 is a deep and thin reservoir, low permeability, natural energy shortage of oil, crude oil has a high freezing point and high wax content. Since 1993, in order to improve the overall development effect of reservoirs, deep-pumping of hydraulic pumps, high-pressure water injection of plunger pumps, integral fracturing of reservoirs and reservoir monitoring technology have been successively adopted. Through the application of four supporting technologies, the production capacity of the oil well was increased so that the opening rate of the block reached 96% and the total production of crude oil was 303571t. The average daily oil production of this oilfield rose from 65t / d to 212t / d, which was The development of similar reservoirs provides a reference model
