摘要

冀东油田大斜度井分注中,常规偏心配水器存在投捞困难、测调成功率低的问题,普通同心配水器则存在小注水量配注合格率低、注水量难恒定、测调扭矩大等问题。为此,研制了一种新型直读测调偏心恒流配水器。该配水器设计了V形水嘴、小直径陶瓷柱塞和偏心调节阀,采用齿轮传动方式调节水嘴开度,降低了漏失流量,提高了注水量调节精度;设计了恒流控制机构,可消除注水压力波动影响,实现恒流注水;设计了桥式通道,可在不同工况下持续提供水流通道。该配水器具有小流量精准配注、连续测调、测调效率高、注水量恒定等特点。在冀东油田大斜度井成功应用25井次,测调成功率为97.6%,配注合格率为92.7%,实现了高效精确测调和恒流注水。该技术可满足大斜度井多级分注及高效测调的需要,提高注水效果。

Abstract

In the separate injection of highly-inclined wells in Jidong Oilfield, the conventional eccentric water distributor has the problems of dropping-fishing difficulty and low measurement-adjustment success rate, while the ordinary concentric water distributor has the problems such as low qualified rate of water distribution when injection volume is small, difficult to keep water injection volume constant, and large measurement-adjustment torque. For this reason, a new type of direct-reading measurement-adjustment eccentric constant-flow water distributor was developed. The water distributor was designed with a V-shaped faucet, a small diameter ceramic plunger and an eccentric regulating valve. The opening of the faucet was adjusted by a gear transmission method, which reduced the leakage flow and improved the adjustment accuracy of water injection. A constant-flow control mechanism was designed to eliminate the influence of water injection pressure fluctuations and realize constant water injection. Bridge channels were designed to continuously provide water flow channels under different working conditions. The water distributor has the advantages such as precise distribution with small injection volume, constant measurement and adjustment, high measurement-adjustment efficiency, and constant water injection volume. The water distributor was applied to 25 highly-inclined wells in Jidong Oilfield, with a measurement-adjustment success rate of 97.6%, and distribution qualified rate of 92.7%, which realized efficient and accurate measurement, adjustment and constant-flow water injection. This technology can meet the needs of highly-inclined wells for multi-stage injection and high-efficiency measurement and adjustment, and can improve the water injection effect.

Key words： water distribution; water distributor; eccentric; constant flow; measurement and adjustment; Jidong Oilfield
