技术领域 Technical field
本发明涉及油气勘探开发自动控制， 特别涉及油气井钻井节流压力精细自 动控制系统。 背景技术 说 在油气勘探开发工程中， 随着油气勘探领域的拓宽和技术的进步， 油气钻 井过程中对井口回压的控制技术的要求有了极大的提高。 一方面， 采用近平衡 The invention relates to automatic control of oil and gas exploration and development, and particularly relates to a fine automatic control system for oil and gas well drilling throttling pressure. BACKGROUND OF THE INVENTION In the oil and gas exploration and development project, with the expansion of the oil and gas exploration field and the advancement of technology, the requirements for the control technology of the wellhead back pressure in the oil and gas drilling process have been greatly improved. On the one hand, using near balance
书 Book
或欠平衡钻井方式， 以更好地保护油气层， 有效地减少钻井液对油气层的损害、 减少或克服压差对钻速的影响， 有效地降低油气井开发综合成本， 大幅度提高 机械钻速并提高油气井钻探的成功率； 另一方面， 当对泥浆密度窗口非常窄甚 至接近于零的地层进行钻井时， 就必须要求在钻井全过程中维持井筒环空当量 密度恒定， 以保证钻井施工顺利进行。 这样就必须保证在钻井过程中， 无论是 正钻进， 还是接单根、 起下钻等过程中， 都能够及时调整井口回压平稳快速达 到施工要求， 并维持稳定。 Or underbalanced drilling method to better protect the oil and gas layer, effectively reduce the damage of the drilling fluid to the oil and gas layer, reduce or overcome the impact of the pressure difference on the drilling rate, effectively reduce the comprehensive cost of oil and gas well development, and greatly improve the mechanical drill Speed up and improve the success rate of oil and gas well drilling; on the other hand, when drilling a formation with a very narrow or even close mud density window, it is necessary to maintain a constant wellbore annulus density throughout the drilling process to ensure drilling. The construction went smoothly. In this way, it is necessary to ensure that during the drilling process, whether it is drilling, or taking a single root, or drilling down, the wellhead back pressure can be adjusted in a timely manner to reach the construction requirements and maintain stability.
然而， 目前使用的压井节流管汇系统都是采用多个阔件串联的结构形式。 这种结构形式在进行节流控制时， 必须要求钻井液返出时的流量全部通过各个 阀件， 并且通过控制节流阀开度来控制节流压力的大小。 但是， 由于节流阀在 相对开度范围 （0〜100%) 内调节精度和调节强度呈严重的非线性， 线性调节区 域非常窄， 在大流量条件下， 节流阀的调节精度控制难度大， 并且大流量对节 流阔的冲蚀比较严重， 容易出现节流阀失效的情况。 发明内容
本发明的目的是提供一种节流控制系统， 其在控压钻井过程中， 能够使井 口回压在不同压力控制等级范围内精确调节， 并且能够对不同压力等级间进行 无扰动切换， 从而在钻井全过程各种施工工况下， 保证井筒环空中钻井液当量 密度恒定， 使得进行压力窄窗口地层条件下安全钻井成为可能。 However, the currently used killing throttle manifold system is a multi-piece series structure. In the case of the throttle control, the flow rate of the drilling fluid must be required to pass through the respective valve members, and the throttle pressure can be controlled by controlling the opening of the throttle valve. However, due to the fact that the throttle valve has a serious nonlinearity in the adjustment accuracy and adjustment intensity in the relative opening range (0~100%), the linear adjustment area is very narrow, and the adjustment precision of the throttle valve is difficult to control under large flow conditions. And the large flow rate is more serious for the erosion of the throttling, and the throttle valve is prone to failure. Summary of the invention It is an object of the present invention to provide a throttling control system that enables the wellhead back pressure to be accurately adjusted within different pressure control levels during pressure controlled drilling, and capable of bumpless switching between different pressure levels, thereby Under various construction conditions in the whole process of drilling, it is ensured that the drilling fluid equivalent density in the wellbore is constant, which makes it possible to carry out safe drilling under the conditions of narrow pressure window formation.

第三控制压力等级： 由点② J45逐渐关闭节流阔， 使节流管汇节流压降上 升到点③ J4， 此时节流压降可以达到 3ΔΡ; 这一阶段压降的调节大小是 ΔΡ， 节 流产生的回压由 Ρ0+2ΔΡ增至 Ρ0+3ΔΡ; The third control pressure level: gradually close the throttle width from point 2 J45, so that the throttle pressure drop of the throttle tube rises to point 3 J4, and the throttle pressure drop can reach 3 ΔΡ; the adjustment of the pressure drop at this stage is ΔΡ, The back pressure generated by throttling is increased from Ρ0+2ΔΡ to Ρ0+3ΔΡ;
第四控制压力等级： 由点③ J4 逐渐关闭节流阀， 使节流管汇节流压降上 升到点④ 此时节流压降可以达到 4ΔΡ; 这一阶段压降的调节大小是 ΔΡ， 节 流产生的回压由 Ρ0+3ΔΡ增至 Ρ0+4ΔΡ; The fourth control pressure level: gradually close the throttle valve from point 3 J4, so that the throttle pressure drop of the throttle tube rises to point 4, the throttle pressure drop can reach 4 ΔΡ; the adjustment of the pressure drop at this stage is ΔΡ, throttling The generated back pressure is increased from Ρ0+3ΔΡ to Ρ0+4ΔΡ;
第五控制压力等级： 由点④ J逐渐关闭节流阀， 使节流管汇节流压降上升 到点⑤关井套压。 The fifth control pressure level: gradually close the throttle valve from point 4 J, so that the throttle pressure drop of the throttle tube rises to the point 5 to close the casing pressure.
5.如权利要求 4的方法， 其特征在于： P0设为节流管汇下游出口的真实压 The method of claim 4, wherein: P0 is set to the true pressure of the downstream outlet of the throttle manifold
