塔河油田超深井试井工艺技术

Well Test Technology for the Supper Deep Well in Tahe Oilfield.

针对塔河油田埋藏深、高温、高压、油稠、产量大 ,常规试井工艺无法满足试油要求的情况 ,配备了能容纳直径 2 .4mm ,长度 75 0 0m钢丝的液压传动试井车、电子加机械式计深装置、罐铅加重杆、EMP S6 2 0高精度存储式电子压力计、耐压 4 5MPa防喷管等先进的试井设备 ,在已完钻的 75口井获得了 6 10 0t/d的高产油流。

According to the special characteristics such as deep bury,high t em perature,high pressure,high viscosity and large production rate in the Tahe rese rvoir,the normal well test technology is unable to fit the special test require. We developed a new test system with 2.4 mm diameter,7500 m long cables,electro a nd mechanics verify equipment,weighted role,EMP S620 electro gauge and 45 MPa well head equipment.75 wells have been test by using this test system.
