The main gas bearing formations at Yulin region(well Shaan 141 area)of Changqing gas field in Eerduosi Basin are the high impedance sandstone reservoirs in Shanxi Formation,Lower Permian,Upper Paleozoic.The seismic works were beforehand involved in the natural gas exploration and well location disposition at the region in 1996.On the basis of the high resolution acquisition of seismic data,a set of techniques of effectively interpreting the thickness of the sandstone reservoirs in Shanxi Formation and detecting the natural gas in them are founded through emphatically adopting 6 items of characteristic techniques as the interactive refraction wave static correction and frequency division processing,etc.,and applying 9 items of reservoir lateral prediction techniques as the logging constrained seismic high resolution inversion and high impedance sandstone reservoir AVO analysis,etc.14 locations of exploration wells were provided for the sandstone reservoir of the second member of Shanxi Formation and the prediction success ratio was up to 85.7%.Because of this,some important discoveries and significant advances have been obtained in natural gas exploration in Upper Paleozoic in the basin and the proved and controlled gas reserves of near 1 000×10 8m 3 were found at Yulin region in 1997.

Drilling fluid viscosity has greatly affected gas detection logging. The experimental analyses of gas detection of various viscosity under different drilling fluid systems are made. Comparative relation of gas detection total hydrocarbon monitoring of different systems is worked out according to the experimental results. By optimization of the viscosity application scope of the different systems, the optimum viscosity value is deter mined. Logging gas detection interpretation standards of different drilling fluid systems are established, taken an example of the gas dectection interpretation standards. In fact it is necessary and feasible that the gas detection logging material is calibrated under different drilling fluid systems.

In view of the characteristics of shallow-layer gas, such as shallow burial depth, complex genesis, small reserves, low abundance, many types and wide distribution, an improved AVO identification method is presented to predict the range of distribution of shallow-layer gas. This method is to determine the scope of angles in a gather through scanning and select an angle gather that can effectively reflect the nature of the shallow layers on the basis of conventional AVO identification technologies. The scopes of amplitudes with different angles are not the same due to the impacts of whether containing gas or not. Energy envelope differential profiles at different angles are generated to indicate favorable gas-bearing areas. The advantages of this method include: the angle gathers are selected aiming at shallow layers, thus can better reflect the nature of the shallow layers; ② the application of energy envelope difference can reflect the small changes of seismic energy at different angles, resulting in a higher resolution; ③ the systematic error is lowered. It is successfully applied to detect gas in Heidimiao reservoir of Punan oilfield in the southern Changyuan, Daqing.

针对浅层气具有埋藏浅、成因复杂、储量小、丰度低、类型多和分布广的特点,提出了一种改进的AVO识别方法来预测浅层气的分布范围。该方法是在常规AVO识别技术的基础上,用扫描的方法来确定一个道集内的角度范围,优选出能有效反映浅层信息的角度道集。由于受到是否含气的影响,不同角度下地震振幅幅度不同。据此计算不同角度下的能量包络差剖面,进而找出有利的含气区。该方法的优点是:①由于是优选的针对浅层的角度道集,所以更能反映浅层的信息;②采用的是能量包络差的方式,可以反映出不同角度下的地震能量细微的变化,使识别的分辨率更高;③减小了系统误差。应用该方法在大庆长垣南部葡南油田黑帝庙油层进行了天然气检测,取得了令人满意的成果。
