摘要
随着电缆地层测试技术的不断发展,一种新的电缆地层测试仪(RDT)把新型的数控技术与地层流体取样及压力测试技术结合在一起。它的主要特点是提高了储层流体采样质量。采用数控反馈系统的泵排设计可使测试仪能连续监控被采样流体,从而能精确控制从地层流出并注入采样室流体的速度与压力。分别就仪器的组成、功能以及其用途作了简单介绍。测井实例证明采用这种新的地层测试技术是先进可靠的。
With the wire-line formation-testing technology further development, a new wire-line formation tester has come into use, which incorporates new digital control technology to significantly improve formation fluid sampling and pressure testing. The new tester has improved the quality of reservoir fluid samples. The tester can continuously monitor the sampled fluid and make precise adjustments to the rate and pressure of the fluid flowing from the formation and injected into a sample chamber because of an innovative pump-out design used digital control feedback system. This paper describes the compositions, application and function of the new tool. Field log examples demonstrate advancement and reliability of the new tool.
