摘要:
 为了解决长时间油管下井过程中压力测试功耗过大问题,提出了一种用于油管传输射孔方式下射孔压力的测试系统。系统采用“单片机+CPLD”的控制模式,其中CPLD控制模拟电路、A/D转换器以及静态存储器以实现射孔时数据采集功能,而单片机主要用于定时功能,控制使测试系统进入自动休眠状态。相比以往的油井压力测试系统,能够在射孔枪下井时间内处于自动休眠状态,在保证能采集到下井过程中静压的同时消除功耗过大的问题。
Abstract:
 To hash out the problem of big power loss during down-hole process in long time tubing conveyed perforation,the paper proposed the design of tubing conveyed perforation pressure test system.This test system controller is equipped with"single-chip plus CPLD".To realize data acquisition,the control analogue circuit,A/D converter,and static random access memory was controlled by CPLD.Single-chip is mainly used in time control and put the test system into state of auto dormancy.Compared with traditional oil-well pressure testing and measuring system,the system operation in auto dormancy state during perforation down-hole process and the problem of power consumption during down-hole process is hashed out while the static pressure is acquired.
