Abstract

According to the characteristics of static pressure and dynamic pressure in oil and gas wells, this paper designs and develops a pressure pulse coding control technology, which outputs control signals after the preset pressure signal is consistent with the impulse code pressure formed after pressurization. At the same time, the bidirectional ignition technology is designed by using electronic switch and positive and negative electric technology. With the combination of two technologies. the application of pressure pulse coding control technology form two kinds of pressure codes, positive and negative electric output, as the judgment standard of control output. The two groups of codes correspond to the positive and negative output of bidirectional ignition technology, which can realize clustering ignition and hierarchical control of oil and gas wells. The technology provides a new set of safe and reliable technology for intelligent ignition of oil and gas field, intelligent control of downhole tools, clustering perforation and other professional fields.

输油管压力脉冲编码控制双向点火技术

根据油气井静压力和动压力的特点，设计开发了一种压力脉冲编码控制技术，在预置压力信号与加压后形成的脉冲编码压力一致后输出控制信号。同时，利用电子开关和正负电技术设计了双向点火技术。两种技术的结合。应用压力脉冲编码控制技术，形成正、负两种压力码的电输出，作为控制输出的判断标准。这两组代码分别对应双向点火技术的正、负输出，可实现油气井的聚类点火和分层控制。该技术为油气田智能点火、井下工具智能控制、集束射孔等专业领域提供了一套安全可靠的新技术。
