摘要

摘要: 为了克服传统油井找水工艺中施工复杂、生产周期长、费用高、准确性低等缺点,提高油井找水效率和准确性,研制了油井找堵水声控压差平衡式开关控制器。该开关控制器采用自适应动态压力平衡系统,其活塞阀开启和关闭时可承受20 MPa压力差;采用油管传输声波信号的声波遥控技术,从地面遥控井下开关控制器开启、关闭,根据工艺要求进行分层开采或分段开采。室内静压试验表明,开关控制器在125℃、50 MPa高温高压条件下,稳压30 min,整体设备无渗漏无变形;耐压差试验表明,活塞在承受25 MPa压差的情况下,压力平衡装置可以承受压差,电机驱动活塞做上下往复运动,动密封不渗不漏。现场试验表明,声波接收器接收地面指令后,可以控制电机驱动装置打开或关闭开关阀。试验结果表明,该开关控制器可为油井提高开采效率提供技术支持。

Abstract: Conventional techniques for detecting in oil wells have been disadvantageous due to their complex process, long production period, high cost and low accuracy. In order to enhance the efficiency and accuracy of the techniques used for water detection and plugging, an acoustic controlled pressure-balance switch has been developed.With an adaptive dynamic pressure balance system, piston valves in the switch can endure differential pressure up to 20 MPa during opening and closing processes.By means of remote acoustic controlled technique that transmits acoustic signals through tubing, the down-hole switch can be controlled remotely on the ground to facilitate production in different layers (in vertical wells) or in different intervals (in horizontal wells) according to operational requirements. Laboratory static pressure testing shows that the switch can withstand high temperature up to 125℃ and high pressure up to 50 MPa for 30 min with no leak or deformation.Differential pressure tests show that pressure balancing device can resist the differential pressure up to 25 MPa on the piston. Moreover, the electric motor can drive the piston to move reciprocally with no leak or seepage in dynamic sealing. Field tests show that valves can be opened or closed by the electric driving mechanism upon reception of instructions transmitted by acoustic waves from the ground by the receiver. It is considered that the switch can provide reliable technical support for enhancing recovery in the oil well.
