川东北清溪场构造飞三段气藏录井特征及解释评价

Mud Logging Characteristics and Interpretation Evaluation of Section Fei 3 Gas Reservoir in Qingxichang Structure of Northeast Sichuan

川东北碳酸盐岩天然气储层所赋存的层位众多,其中上组合海相地层中三叠系飞仙关组储层由于埋深适中,是重要的勘探目标。江汉录井在川东北清溪场构造XQX1井飞仙关组飞三段发现高产、高压、裂缝型气层,测试产量达106.8×104m3/d,控制储量超过30×108m3,是在川东北及鄂西渝东地区继河坝2井后又一口单层测试产量超百万方,且不含硫化氢的碳酸盐岩气井。

There are multiple stratigraphic horizons in the gas carbonate reservoirs in Northeast Sichuan, in which Triassic Feixianguan Group reservoir in the upper marine formations is the important exploration target due to its proper buried depth. A Jianghan mud logging team has discovered the fractured gas reservoirs with high production and pressure in Section Fei3 of Feixianguan Group in Well XQX 1 in Qingxichang structure of Northeast Sichuan, in which the test production rate is 106. 8 × 10^4m^3/d the controlled reserve is over 30× 10^8m^3, and it is another carbonate gas well whose single interval test production rate exceeds million cubic meters per day following Well Heba 2 in Northeast Sichuan, West Hubei and East Chongqing, without hydrogen sulfide.
