塔河油田十区及十二区奥陶系油藏具有超深、超稠、高温、高压、高黏、高矿化度、高含硫化氢的特性,给动态监测带来极大挑战.为了解决塔河油田超深、超稠井压力监测的难题,引进了毛细管测压工艺.该工艺将各种测试元器件全部转移至地面,使整套技术的耐温、耐压及适应井斜的能力较常规压力测试方法得到大幅度提高,且全部实现了压力数据的实时显示和存储,满足了各种生产压力测试的要求.该工艺已在塔河油田TH10315X井成功应用,取得了较好的效果.

Due to the features of super deep, super thick, high temperature, high pressure, high viscosity, high salinity and high content of hydrogen sulfide in the districts ten and twelve of the Ordovician reservoirs in the Tahe Oilfield, it has brought great challenges to dynamic monitoring. In order to solve the problems of pressure monitoring of super deep and thick wells in the Tahe Oilfield, pressure testing technology with capillary is utilized, which transfers all the test components to the ground. Compared to regular pressure testing methods, this technology improves the ability to resist temperature, pressure and adapt inclination greatly, which meets the real-time display and storage of pressure data, and satisfies various kinds of production testing requirement. This technology has been applied successfully in the well TH10315X in the Tahe Oilfield, and has achieved good results.
