TCP+DST+JET三联作测试工艺技术

TCP+DST+JET Combined Testing Technology

TCP＋DST＋JET射流泵学升三联作测试工艺，适用于低压低渗油层的测试。逆向可取式射流泵的工作原理是正向使泵芯入座就位；反向泵动力液使射流泵工作。从油管内返出的混合液进流程分离、计量、取样分析。逆向可取式射流系学升对地层降压效果良好，排举能力较强。通过2口井的试验，证明该联作工艺简单、操作方便、施工工期短，具有良好的经济、社会效益。

TCP+DST+JET pumping testing technology is applicable to testing of low pressure and low permeabilityforimtions. The working principle of retrievable reverse pumping jet pump is that right circulation pushes pumpvalve to sit into its position,while reverse pumping power fluid makes jet pumP work,the mixed fluid flowing outof tubing goes into wellhead process for separation,measurement,sampling and analysis. The retrievable reversepumping jet pump has strong lifting capacity and has good results for formation pressure relief. Throughexperiment on two wells,it proved that this combined technology. with simple design, easy operation arid shortworking period,would have excellent economic and social benefits.
