Application of discovery process models in estimating petroleum resources at the play level in China

Discovery process modeling has gained wide acceptance in the Chinese exploration community. In recent years, a variety of discovery process models have been applied to the prediction of undiscovered petroleum resources at the play level in sedimentary basins in China. However, challenging problems have been encountered, particularly when one method alone has been applied to small plays in nonmarine sedimentary basins or in plays with an unusual order of discovery wells. This paper presents results gotten by using the lognormal discovery process model of the Geological Survey of Canada and the geoanchored method for three petroleum plays in basins with different geologic settings. Although the predicted shapes of the parentsize distributions which use these two models, were not always similar, the expected values of the total resources and the number of fields (pools) to be discovered are comparable. The combined use of two discovery process models in the same play compensates for the weaknesses in one method compared with the other and vice versa. Thus, more reliable estimates are the result.

The Natural Probability Distribution of Load and Unload Response Ratio

In this paper,the Gutenberg-Richter model is used to generate seismic events.The events that satisfy the random distribution are also generated.With those events,the natural probability distribution of Load and Unload Response Ratio(LURR),which measures quantitatively the degree of instability of a nonlinear system,is discussed.The study is based on stress energy release,which is chosen as the response of nonlinear system F3.The comparative results from the observation catalogue and generating data are also studied.It is revealed that the natural probability of LURR is mostly stable when the sample number is sufficient.The lower the natural probability of LURR,the more the precursory is information it may contain.The influence of Y3 resulting from the sample number and the magnitude range of events is also discussed.     

三维地震勘探恢复性放炮法变通问题的讨论

受地物影响，炮点的理论变观方法(恢复性放炮法)只能是三维地震数据采集过程中的一种补救措施而已，它只保证了设计覆盖次数不变的目的，而不能保证道集内炮检距和方位角不变的目的。一方面，变观后要求所有的炮检距均满足最大炮检距的限定条件显得过于苛刻；另一方面，对地层倾角较大或煤层埋藏较浅的勘探区，一个区的最大炮检距允许值也不一定是一个确定的值，通常的做法是取平均值。据此，提出了三维变观80原则，即在变观炮点不多或不集中时，只要变观炮点记录中有80％的炮检距或不低于80％的道满足最大炮检距要求，就可认为变观是成功的。这种实用的变观方法，对三维地震勘探野外数据采集工作有较明确的指导意义。
