吐玉克油田深层稠油油藏构造复杂，储层物性差，单井产量低，以常规的开采方式和井筒工艺无法 实现经济有效开发。通过对吐玉克油田深层稠油进行天然气溶解与降黏室内实验，以及利用GEM 进行 天然气吞吐开采方式的数值模拟与相平衡研究，最终优化了吞吐参数。对3 口井进行了天然气吞吐现场 试验，结果表明：通过采用天然气吞吐技术，吐玉克油田深层稠油单井产量提高了2～7 倍。

The deep heavy oil reservoirs in the Tuyuke Oilfield are characterized by complicated structure, poor physical properties and low single well production, so it is difficult to achieve economical and effective development by using conventional mining methods and well-bore technology. The natural gas dissolution and viscosity reducing indoor experiments were tested on the deep heavy oil reservoirs in the Tuyuke Oilfield. The parameters of the design throughput were optimized by the use of numerical simulation and phase equilibrium studies in CEMway of exploitation on natural gas throughput. The gas throughput field tests were carried out on three wells. The results show that with the using of natural gas throughput technology, the daily production of a single well was increased 2～7 times.
